After reading several posts to find a cure for my HTC HD2 unresponsive touch screen,( Slider wont slide to open applications), I decided to verify a theory. Software... Digitalizer screen, or power button.
Ok, first I Instelled about six different android versions, and the screen slide still failed. I reverted the cell back to original t-mobile windows software, and still locked screen.
Conclussion: The sofware is not the problem.
After several attempts pressing the red power button, I got the slider to open. Briefly, it locked again. Pressed the red button hard and tried to work the slide on the touch screen. Again briefly worked. After several more attempts I got it to slide and while the phone was awake, everything worked perfect. I played games, oppened applications, texted, made phone calls, and the touch screen worked flawless.
Conclussion: The digitalizer (Thin top glass screen on top of the display that responds to touch) is not the problem.
This led me to belibe that the power button was at fault. I called T-mobile and after explaining the problem, they decided to send me a different type of windows cell. I want my htc. So I declined the offer and decided to void the warranty and take matters in my own hands. Yes, I opened my HTC HD2. This is what I found: After about an hour I had carefully taken my htc apart without braking or scratching the phone or screen. When I finaly got to the buttons on the bottom, I noticed how cheap they where made. A thin copper circle on top of two contacts held in place by tape. Yes you heard right, tape. After a while, beating on the red end key for maybe a year or two, the tape brakes and the metal piece slides to the side, and makes the button to malfunction, that's why the hard pressing to make it work. I tried A bottle of comppressed power air to clean them before disassembling the phone but the way they are installed It's not possible to clean them like that.
Conclussion: The red end key is faulty.
I decided to keep the cell alive so I went on e-bay and ordered the buttons, and just in case I also got a new digitalizer for testing purpose.
The buttons panel was about 4 dollars and some change, and the digitalizer (touch screen) was about 14 dollars for a total of less than 20 bucks. (Worth it)
So here are some pics of my cell buttons, and what it should look like. After I get the parts and assemble it I will conclude and let you know the final and official veredict. As of now, it all leads to the button.
Please do let us know how you got on. I have a HD2 which I'd like to get up and running again so I can play with custom roms and leave my other mobile alone...lol. Any chance you could link to the places you got parts/tape from, and what tools we would need?
Cheers! :good:
Did it worked ??? i am also in the same situation...please share the details,

listening in as well
sheesh! my wife's HD2 also stop responding yesterday, seems like clockwork that a lot are having the same problem
first have to find "how to open your HD2" w/o breaking anything in the process :silly:
Damn. The second time I'm hearing about the red button giving problems.... Will be waiting results from you dude!!! +1
still wayting for the parts
Well, I am still wayting for the parts, they are on the way. The parts I found on E-bay. The buttons panel was about five or 6 dollars, I also got the digitalizer which was about 15 dollars. As soon as I get the parts, I will assemble my hd2 with the original digytalizer (the thin top screen) and test to make sure the buttons were the problem. If all goes well, I will post a complete test result with links to how to get the parts, a link on how to dissassemble the hd2 and all info I can to help on this issue. I did a step back in life, and pulled out my trusty 7 years old motorola razr v3 and stuck my sim card so i can talk and text 5 words in 7 minutes. No internet... I need my HD2... Well, I will report back as soon as I can. Thanks for the wait...
@dragonsuicida
will be waiting for your findings & ways to dis-assemble the HD2 :fingers-crossed:
You were lucky to find the buttons' panel for 4bucks. I just checked out Ebay india, and the panel is 40bucks!!! What a robbery!
Wow. Me too!
I have been running Win6.5 still on my HD2, and have found in the last few days, my screen locks and I can't unlock it.
I came here deciding it was a software issue and was going to look into putting Android on my HD2.
I was slowly coming to the conclusion that it was the power button.
If I make an effort to NOT touch it - my phone seems happy.
It's amazing that we're all having the same problem about 2 and a bit years down the track since the HD2 was released - almost a built in expiry!!
And yeah - lots of details on how to fix it would be great.
The HD2 is too good-a-piece of hardware to allow a ****ty hardware button to be the cause of it's death.
New Keypad Button Flex Cable Ribbon For HTC HD2
Copy this:
New Keypad Button Flex Cable Ribbon For HTC HD2 T8585 and paste it on ebay, it will bring the buttons for the htc hd2. I belive they all come from china, but after I test them I will let you all know if they work and if they are worth it.
Copy this: REPLACEMENT DIGITIZER TOUCH SCREEN LENS for HTC HD2 T8585 and paste it on e-bay and it will bring you the digitizer for the hd2.
copy this: http://www.youtube.com/watch?v=YdOC3Xxo_k0 and paste it on your web browser, and it will lead you to a video on How To Replace Repair Disassemble Screen Digitizer. When it gets to a part that say that you have to put the phone in a oven, is just to melt the tape or glue holding the screen to the phone. I just used a hair dryer to war the screen enough to carefully remove the screen and the digitizer from the phone without breaking them, It works. I will be back soon with more info. I believe my digitizer screen is on the mail box now. Will report back...
I have same problem. Today I bought a flex cable ribbon and waiting for the dispatch (estimated in 2 days). I will also report back..
Same problem here!
Hope to hear soon that this is the way to go to fix it
You have to stick back the tape in the housing. The tape is electrically conductive. It connects the ground of the keyboard flex cable with the ground of the housing.

Be careful! There are two types of digitizer:
- Solder version http://www.parts4repair.com/htc-touch-hd2-touch-screen-with-digitizer-solder-version/
- Socket version http://www.parts4repair.com/htc-touch-hd2-touch-screen-with-digitizer-socket-version/
Be very careful when ordering parts, specially the digitizer they have several kinds, solder and socket, and different socket sizes. Compare parts with the ones in your cell to make sure, don't just believe the advertisements.
Hi, any updates on this? I'm also having this issue, but in my case, even pressing end call really really hard doesn't solve the problem... snif..
+1 on that
i pressed all the keys even the lower part of the LCD & flashed new roms but no joy :crying:
will bring to shop instead I'm afraid to open it up, it might end up even worse
Just be extremely careful when you try this. That flex cable is so incredible fragile and easy to tear. My roommate tore the volume rocker section right off of his HD2.
Hi dragonsuicida
Were you able to get your touchscreen to work?

Ok so I have the fabled white screen issue on an 8525. When it first occurred I searched and read all the write ups, decided I had the ribbon cable issue. Took it apart and simply unplugged and replugged the ribbon cable with great results, no more white screen.
I repeated once when it came back after being bumped around, again with positive results...but this last(3rd)time instead of it working I now get white screen 95% of the time. I re-notched the sliders the first time, and last time.
During the 5% it works I noticed the charge light would correspond to it going white.This never happened before...
Example:
When OFF - Connect charger, Red light for 1 second, then nothing=White screen from power on
When OFF - Connect charger, Red light for 1 second, then orange charge indicator = normal startup
When ON and Working - Connect charger, no light, no charge - reboots to white screen
When ON and Working - Connect charger, orange charge indicator, reboots normally.
There is no heat or noticeable pressure on any parts, everything seems to fit normally.
It does boot normally with screen white.
Any ideas? I really don't want to give up on this thing, is there any hope? or just ebay it for parts?
Thanks
-Nick
same problems here, if someone could just tell me what parts to order, cause I have no warranty (ordered over ebay). I tried both the instruction that has chinese fonts on the page , and other from R&R, no luck, white screen all the way..
I had the WSOD and took it apart and reassembled a few time. The 3rd or 4th time the screem came back, but now it is shifter to the right around 1/4" or so. I mean there is just white along the left edge, then the normal screen/color starts and is cut off on the right.
Does anyone know how to correct that, is it related to the same flex cable or is there something else I disturbed?
mine will fade to white.. then i just push the power to put it in standby, then push power again to wake it back up and back to normal.. it rarely does it but still annoying...
If You Ordered From At&t
I had this problem about 2 weeks ago!!!!
I thought it was a fluke!
Anyway, walked over to 43rd and Lexington (NYC FOR THOSE WHO DON'T KNOW THAT MANHATTAN IS THE CENTER OF THE WORLD)
and they gave me the EXCHANGE HOTLINE for at&t.
I called them up, told them my screen is fading to WHITE and the lady sent me a new or referbished phone.. i dont even know.
Just so you know, i ordered my phone on AMAZON with a new activation. its covered under the MANUFACTURERS warentee for a full year from the date of purchase... so is the REPLACEMENT PHONE... but not from the date of replacement, just the date of purchase.
did anyone get deeper into this yet? I got a 8500 (need those without camera) from ebay USA, already with white screen. After reading here, that this is mostly an issue with connectors, I bought it, disassembled it and reassembled it, though still white. Should I give the contacts a treatment with contact-spray? (there's a tuner spray that doesn't leave residues) Or is there something broken within the ribbon cables? Seller said it has been dropped (but he also said, he didn't want to open it, while it clearly has been opened, one screw missing and warranty seal gone). It ssems to boot up normal otherwise, I hear a sound after the boot process, so probably this isn't a software issue?
Edit: another thing I noticed: When I run it without any keyboard connected at all, it's also white. I then connected the dpad again, and I could see a hint of the at&t logo in the lower part of the screen. When I pressed around on the back of the dpad a bit, all LEDs would go on/off... Sound to me like the dpad has gone bad, possible?
Edit II: Got it. Using a 20x eyeloupe I found that the PCB of the DPad is broken under the little chip on it. Now I just gotta find a dpad here in germany, but I assume those Hermes' are all equal...
hello
where can I get manual (if there is one) for disassembling hermes. link in wiki does not work.
thanks
this worked good for me
http://inuchanbt.blog54.fc2.com/blog-entry-100.html
Anyone know if this applies to the 8125 as well? I've got a flickering white screen. I had dropped my phone a few weeks back and cracked the LCD. Replaced it with an OEM LCD - it worked fine for about 2 weeks and then just suddenly went all white. Phone still works, I can still get calls - just can't see who is calling.
I don't recall that the wizard had the same problem... Though from a logical point, it seems that there is an issue behind white screens and the thumbpad being responsible for it, so it may well be the same thing. Perhaps just disassemble the wizard (there should be a howto too) and check if theres a similar connection from mainboard to thumbpad circuit.
Is there a disassembling manual for a imate k-jam that anyone knows about?
Here's a website with a video manual i found useful...
http://viralelectronics.com/category/howto/page/2/
Figured out the problem...
The only reason I figured out the screen goes blank is because the motherboard loses connection with the screen when you slide the keyboard out...try this out and see if the screen comes back...
put the screen on sleep mode (no white screen)...then slide out the keyboard and tilt it a little hard after pressing on the screen and put the power on. if it doesnt work try again it might take some pressure and power to make it work...be careful not to put too much power but as far as I went, it's a very sturdy cell.
alternately, slide out the keyboard in sleep mode, and press all the buttons really hard and then try to press the power button (press more towards the space bar because that helps)...if any of this works and the screen comes back on even just for a second...follow the following
Go back to the person who gave the link to the site with opening the HTC instructions and follow through and clean the whole phone up from dirt around the screen and such...you dont need to put those rubber things or whatever it says to put on the screen...then when you are putting it back together, press hard on the wire connecting the touch screen to the motherboard. I suggest sealing it with a good tape...and then you are good to go! I did it but it had a few glitches...the screens contrast sometimes goes awry but it is still visible and responds to touch. Also, the physical buttons work as well!!
Good Luck and do it at your on risk.

fixed my wsod
I noticed a few days ago my 8525 screen went white, rebooted and it went away. Today it came back, but would only go away for a few seconds and then back to white. After reading some forums I decided to check the connector. I took the phone apart following this site as a guide. I removed the connector on the board side and cleaned the contacts with a qtip and denatured alcohol. Phone has been perfect for the last few hours, no more white screen of death. I didn't mess with the connector on the LCD side, just the board side. I'm a computer tech and I found it quite annoying to disassemble, but I managed without causing any damage, however, I'd rate the job at about a 8/10 as far as technical ability.

i agree that this is one of the first things to try in curing the white screen issue. Others may find their problem runs a little deeper and the contacts on the d/pad chip are broken. An improvised cure which may not be very permanent is to place a little padding on the surface of the chip as described here:
http://forum.xda-developers.com/showthread.php?t=321163
If you have appropriate heat gun equipment you can re-flow the solder on the d/pad daughter board - but remember to remove the sticky key pad layer or you'll cook it!!
I regret that I'm closing this thread because we have several "White Screen" threads and the questions and answers are being spread all over the place.

hi everybody.
some weeks ago i bought a new casing for my trinity on ebay. as I had to open my trinity while on a long trip far away from home and htc tech support (the "hang up" button broke), i had already broken my guarantee. so i decided to change the casing myself. i managed to do that (it was not easy!!) and closed the casing and everything was alright, but some days later trinity started to have graphics issues. sometimes it hangs and the display gets kind of scrambled, when i reset it it posssibly doesn't show anything on the screen or it hangs during the boot, sometimes it helps simply shutting the device down and restarting, sometimes it helps pressing the left side of the casing (front and back casing elements) together.
what can that be? at the moment it works alright, but this is not ok for me. somebody with hardware know-how can tell me which part can be the "bad one" and what i can do to fix that? i don't want to pay the repair fee at htc tech partner, and i want to wait till the htc touch cruise is available to buy a new one!
thanks

Hi, I did similar thing...I assembled my trinity to change case to white. After the LCD did not work at all.
Of course service said, I broked garantee, and there is some problem with LCD cable plug.
what did the repair cost?
did you go to HTC? did they change the display plug?
it's a very subtle error in my case...
How To Disassemble HTC P3600
I also want to change my casing.
From what I hear ... this may be not such a good idea.
Hoever ... all I can help with is this disassemble manual for HTC P3600 (http://rapidshare.com/files/82751326/How_To_Disassemble_HTC_P3600__Trinity_.pdf.html).
Maybe disassembling, cleaning all the plugs and assembling it again can help (sounds stupid ... but who knows).
thanks ..
one of the problems with the casing i bought was that the metal counterparts of the screws were not(!) present in the new one. so i had to cut them out of the old one, heat them and press them into the new case. luckily, i had ordered two new casings (to change it again after some months when the grey/silver paint would have fell off till total aesthetic destruction - of this otherwise really slick phone - again), because trying to press that counterpart (don't know the word) without heating resulted in total damage
then I had hoped that not only the keypad, but also the electronics plate under the keypad (my "hang up" button still isn't perfect i have no "klicky" feel any more) would be included. no luck here.
so everybody please stay away from trying to change casings or any other hardware issue with your htc phones. i am opening my htc/qtek (before: s100, three units) phones for a longer time now and must say i will stop doing that and return to being a "normal" user. it all gets worse
thanks
I just remembered ... take a look at this site: http://cnn.cn/shop/p3600-trinity-c-277_278.html
All the stuff looks genuine ... maybe this casing will fit you better and there are spare touch screens also.
P.S. White casing DOES NOT peel.

I went to E-care, the HTC support in Hungary. I was lucky, the expert repaired it free, but in the future there is no garantee
Lucky you ... there is HTC support where you live
my LCD screen broke.
I have replaced my LCD screen because it was cracked, the new screen does not even power up. I can hear wm6 running in the background but the digitizer nor the screen seem to be responding at all. If use the old screen it seems to work fine.
Any ideas or comments on how to get this new screen working?
btw, I have a gen1 htc p3600.

hi,
since yesterday, my niki doesn´t response to touchscreen tapping if the slider is opened. i hear a very quiet metallic clicking sound if i open it up... if i try tapping the touchscreen before this little click appears, the touch works... but with slider open completely, it doesn´t. i guess this is hardware specific. i´ve tried a hardreset now, but still doesnt work any advice?
EDIT: i didnt flash any other radio...
EDIT2: sometimes it does work.
Sounds like a ribbon cable has come loose to the touch screen - send it back if it is under warranty, if not, Mike Channon has collected links to the service manuals somewhere on here which should show you how to correctly take it apart, fix it and put it back together again
Cheers,
Smiffy
I had the same problem. In my device it was: cable that goes to touch screen contacted metal on back panel.
I've solve it by finding manual to take my niki apart (http://www.pdacenter.ru/razborka/razbor_htc_touch_dual/ - but it is in russian). I've done everything till 6 point. Then I put my v-card between this cable and metal. Now it's ok
I've got extra service on mine.
6 euro's a month.
handed in the phone today (same issue), and got given an new one! ;D

You ROCK! I had this exact same problem happen on my NIKI100 after I put Tom's Niki Project ROM on & immediately blamed it but after flashin back to stock the problem still occured & I was really bummin! I found this thread, tore my NIKI apart to step 6 as you described & I could see the spots on the metal of the inside back of the back cover where the cable was rubbing along with the protective plastic worn off on the cable a little bit so I suspect it was touching the metal & shorting out causing the problem (heck I'm surprised it didn't do some real damage!) so I cut about a 1" length of electrical tape & taped it to the area of the metal that it was rubbing on (I didn't see any legit reason for anything to make contact to that area for a ground so I figured it was OK. I started at the edge & ended just before the gaps where you would be able to see the tape from the other side in the battery cavity) and VOILA! it fixed it! To me it looks like a nasty design flaw on HTC's part but not expecting a recall any time soon. I suspect this fix will out last the phone & hopefully this thread will help others. I am 1/2 tempted to tear apart my NEON to see if the same design exists or if they put a piece of tape in that area.

Hm, same problem here. Thought first that it was an error of the ROM that I used..
Btw: isolated every contat that I could find (nearly ) but no result -> still my touchscreen doesn't work when my slide is open..
EDIT: has anyone PHOTO'S of their disassembly and isolation work? I the problem is different on my device 'cuz the cable hasn't worn off...
Ok,
Now I took my device apart to the last piece, took the display cable apart, taped it in completely and my touchscreen WORKS once again :-D.
Woot! Thumbs up for XDA-developers!
EDIT: Now my touchscreen doesn't work when slide's closed... Any suggestion?

ive brought my dual to a vodafone shop and they have fixed my dual. Replaced a part and software update, got windows 6.1 now, legal and my screen is working like a champ!
I have had the same problem with my touch screen except mine stopped working completely, it didn't matter if it was slide out or not. I could get the phone replaced on warranty though.
Just posting so people know this isn't just isolated case.
mine slowly stopped working.. im gonna disassemble later and try this. im glad im not alone
edit: worked a treat. some insulation tape on the metal shielding worked great.
That did't work for me! Can it be something else or is it the flex cable for shure? I'm considering buying a new flex cable on ebay! Will that fix the problem with touchscreen dos'nt work when slide is open?
theres a 99% chance that its the flex cable.. did you check it for any damage? mine had tiny tiny little dots with wire exposed. barely noticable but it was enough. try taping the cable. i dont know. if not, i'd get a new cable for sure.
It's worth a try. I've just bought a new cable. Hopefully it will make my
Dual working again. Now I just have to wait a week for it.
The cable arrived today and my dual now works perfect. Now the question is which phone i'll use, my dual or my new Diamond.. =)
hey, where did you get yours from? and how much did it cost?
i have seen ebay, but they are over 30$US including shipping.

Hi, I come on here quite a lot for information as it's an amazing resource! This time however, I'm attempting to give something back!
I experienced the "black screen on slide out" on Monday. Phone completely screwed. I've also had a few droppages and had it apart once before so there's no way warranty is gonna help!
I stripped it down and soon discovered what it is that actually fails on the ribbon. The coating had worn through due to rubbing on something during the slide out / in process. it had been playing up for a while, probably due to shorting out on the metal case, but now the tracks (aluminium?) had worn right down.....
In pic 1 i've circled the worn area. The shiny section is where i'd tried taping over it to prevent shorting, before i realised the tracks were gone.
Got an almost new one off ebay for 15 quid and, realising it was going to happen again, came up with a solution that, so far, looks like it will work....
A while back I bought some "anti rattle felt" for my car's dashboard - really thin and strong self adhesive felt to prevent squeaking joins between dash sections. I cut a piece of this and stuck it to the new ribbon. Once this stuff is on it's well stuck, by the way!
See pic 2 for the modded ribbon cable.
On reassembly everything is working just fine so far! Here's hoping that it lasts longer than 6 months this time!
Just need a new casing now as mine is decidedly second hand!
Hope this turns out to be of use to someone!
cool story bro
when i took apart my xperia to replace the housing this seemed like a really weak point in the device. glad to see someone who has had the problem has been able to fix it
Why does the screen go black?
Hi,
When the coating wears off the ribbon cable it exposes the tracks in it. when you slide the keyboard out the exposed tracks short out on the metal casing and the screen loses it's input signal.
thats whats happened on mine at least and i presume quite a few others?
HTH!
Update:
That's interesting: My phone was also losing signal with the keyboard out, and occasionally while closed up as well. It would just randomly drop to "no signal" for a few seconds.
It hasn't done it since replacing the ribbon cable.....could be coincidental of course.
I'm having the same problem
It just started a week ago and I got the phone in January off of ebay. I'm new to opening up the phone so could anyone help me find the correct tools or have a link to a site with pictured instructions?
I noticed that the sliding mechanism started to go loose about 4-5 months ago but didn't expect the screen not respond in landscape mode. I have yet to see the other symptoms you all are referring to. I would like to fix this before it get worse.
In mine case it went totaly black after one week of this problem... You have all the instruction on youtube, there is where i looked. For tools you can be inovative, but the exactly right ones come with housings from ebay, it is only 15EUR, and i bet you have some cracks so it wouldn't hurt replacing. That is what i did, along with ordering new sliding mechanizm, and new ribbon cable.
I am open for ideas to prevent my ribbon cable from being cut at it weakest point again.
I'm assuming my flex ribbon went bad yesterday, since sliding the keypad out causes my screen to shut off.
Already ordered a cable off ebay and will attempt to replace it myself :O
Replaced my flex ribbon cable with one I bought on eBay. The screen doesn't turn on at all now, which leads me to believe the cable I was sent is defective. Put the old one back in and it works okay, less landscape mode. ughhh what a pain.
great tips! my input is I bought a case off of ebay that was ~60$ and everything actually fit fine for me...so I wouldn't discount every seller but you do get what you pay for, the 15$ cases are probablly the ones that will give you problems
I working in a mobilephone repair center if anyone need help drop me a priv... i able to get 2nd hand or even brand new components
Replaced the flex ribbon cable -
I got my flex ribbon cable a few weeks ago and took it to my local repair shop. They replaced it but the LCD screen/optical joystick receives no power. The touchscreen and everything else on the phone works just fine now. I thought it was a defective item so it was exchanged with a new one.
Got the repair shop to replace it again and the outcome still remains the same as the first.
Theres no light coming from the screen nor the side illumination.
I just told the repair shop to just place the original back in for the mean time.
Before the repairs, there would be a flicker of white light and random illuminations. Now there's no lights at all except the power botton.
Could it be defective a batch that the seller was sending out? or the repair shop's mistake and is playing dumb so they do not have to admint fault?
Hopefully there's an easy fix to this problem.
-Also I did inspect the ribbon before and after the repair. looks new as the OEm
Can anybody help me out with this new problem after replacing the cable -
perhaps you should try a hard reset. Ive had problems in the past where the optical joystick and the illuminators did not work, and that worked for me.
On the other hand, the top illuminators are on the same piece of hardware as the flex cable that was replaced, so a faulty flex cable is possible. The bottom illuminators are on the circuit board that the optical joystick attaches to, separate but connected to the flex cable.
Ive recently replaced my flex cable and touchscreen. The experience i had with the faulty touch screen was that it appeared to receive no power, but was in fact displaying a dark backlit illumination that could only be seen in the dark. At the same time however, the screen did not display anything. I'm not sure if this is similar to your experience, but if so then your touchscreen would need to be replaced.
ive done all repairs on the xperia myself, and one thing ive discovered is if something doesnt work right after a repair, simply disassembling it and reassembling it to make sure all the connections are properly done has worked for me in the past.
"Before the repairs, there would be a flicker of white light and random illuminations. Now there's no lights at all except the power button."
Now when you say the power button, do you mean that a red light appears under it?
I dont know if i can come to a conclusion or that i can help (or have helped) you come to a conclusion, but i can only assure you that the xperia acts out in strange and weird ways.
Good Luck!

Thanks for the links. I've tried the hardreset and restoring the original rom but the issue is still there. It's really bugging me that everything works but the LCD screen. I'm currently using MyMobiler to use my phone. The touch screen works fine and so does the soft keys. Just no power for the lights. I might just give up and wait for another phone that catches my eye and then tinker with the xperia myself. but if anyone got a solution or want me to test something then I'll give it a try.
My warranty is no longer affective so I'll use my phone as a tester to help others with any problems.
TRIONDAVE, how's your Xperia running now with the cable mod that you did? Its been 6 months since you created the thread. I hope you're still around.
My Xperia X1 works nearly fine, except for the keyboard issues, so I'm thinking of opening it up. If your Ribbon mod helped I might just do it too once I've got it opened. Mine has a MOUNTain of cracks though, and the battery compartment itself is cracked on both side enough to make the compartment CURVED. Hence the Battery cover doesn't sit well.
I'm looking around for broken Xperias which I might be able to use to change the internal cracked casing. Lets see.

My thoughts exactly.
Hello guys, I am in need of real help over here!
Its just that Ive replaced my ribbon cable, the old one got screwd up.
However I got done for 10 minutes ago, tried to start up the phone.. without success :,(
The ribbon cable doesnt have anything to do with the start up, only the screen am I correct? Cause I cannot even start my phone..
Ive connected the charger, but when I remove the battery it shows a red light, meaning no battery, correct?
So what may the problem be exactly? Maybe the battery is all dead, or?
PLEASE HELP!
for the people with ribbon failures how long have you had the phone before it occurred ? im just interested on the cables lifespan.
mine is fine so far but i have noticed the slider is flimsy and rocks left and right.
Hello Gents and Gals. I am trying to fix my friends HD2, I flashed his ROM with Energy couple of months ago and all was working fine. He gave the phone back to me saying that it is locked.
I tried unlocking the phone but it seems that the screen is unresponsive, so I flashed it again by going into the boot loader screen "Volume Up + Power Button". The phone stated that it is starting for the first time but the screen was still unresponsive. Any ideas on how to fix this issue? Or do I need to tell him to send the phone back to HTC for repairs?
Sounds like the touch screen died ....
Time for a repair ..
Also this really should have been posted in general , as it is not a ROM release , just an FYI
Aww okay. I'll let him know. Thanks.
I'll post like this in General next time. Tks.
HI, I have now the same problem after ROM Flashed, did you solve the problem by yourself, or really the touch screen died.
Rgds
Same thing with me. I ordered new digitizer+LCD and changed them, but the screen is still unresponsive. Other ROM didn't help.
Some advices?
i seen this happen with several phones, reflash to stock and send to HTC they will repair it for free.
I have same problem,yet my phone was bought 18 months ago...worked perfectly until now.
Can a touch screen get defective after normal usage ?

Yes it can, if your touch functionality of your HD2 has stopped working then your digitizer has probably went out.

Yeah,that's what i thought too - but i read some situations where replaced LCD + Digitizers didn't solve this problem.....

This is usually due to the replacement components not being properly installed. Also when one is working with the internals they have to be very careful as some of the internals are very easy to break without you even knowing you did. So the cases you spec of are more than likely not because it was not the Digitizer or LCD was not the problem, but human error.
i fixed mine and it didnt cost me
the unresponsive screen maybe the digitizer buts its more likey the end call button, believe it or not dirt can get behind the contact or because the back button is next to we use the far edge of the end call button thus leading to bending the contact, when any of this happens your screen will be unresponsive
you can either take it to a shop and pay for a new screen and digitizer or take it apart and clean the contacts
go to ifixit for step by step guides
hope that helps

I have no idea what are you talking about, that doesn't make sense, as far as I know is no direct relation between END button and (non-working/responding) touchscreen: you may even disconnect/replace bottom buttons ribbon/flex from motherboard and touchscreen will work if OK(or not, if defective).
Is there anybody who can confirm this(or not)?
3 weeks ago I had a LCD/digitizer replaced (cracked screen, but was still working) all was great till 2 days ago. Screen stopped working - took it back to the place I had replace the screen and they tried 3 brand new screens and still no go. Ended up being my main board - luckily I had a spare HD2 and they pulled that board and all is well again.
Believe it or not your LCD/digitizer might be fine - find someone or a way to test main board would be where I would start after the last 3 days.
Good luck
PS - I did NOT try the end button idea prior to the repair.

If still in your possession, I would be interested to buy the motherboard you just replaced!
PM me if interested!
htc hd2 screen died
I also have a 2009 htc hd2 on which screen does not work.
I'd like to know if it's
- a common problem
- is it possible that it's a software (flashing) issue
- can it be replaced and for how much

From my own experience :
1. It's a common issue, there are hundreds of reports in this forum and I read them all because I had the same problem some months ago
2. Probably not. It's generally hardware-related and often the digitizer (touch responsive screen) . Brief explanation : There's a flaw in the design of the HD2, the thin cable wiring the digitizer to the motherboard, is just below the power button. After some extensive use of your powerbutton, it might happen that the power button touches the cable and cause some kind of shortcut in it which makes the digitizer unresponsive to the motherboard.
3. I replaced mine here : http://www.htcphonerepairs.co.uk/ . Fast repair, secure shipping to Belgium, good price and excellent customer support. (Sounds like advertizing but I swear to be only a happy customer )
There are also multiple videos on youtube explaining how replacing the digitizer yourself if you dare !
Also, I read answers saying that you can somewhat "play" with your buttons (especially the power one) to turnaround the problem. That's correct, BUT it's absolutely inevitable that the problem with come back again if you use the buttons, and you'll have to force more and more to unblock again and repeat again and a again... and that will damage your button bar.
I did this during almost 2 months and that put down all my buttons and now they are really close to the chassis which is very annoying. If only I knew it before I would have replaced the digitizer directly !
For 6 months with my new digitizer + using ICS with soft buttons, I have no problem at all !

Just because this dude has "no idea" it doesn't mean he knows it better.
It IS the END button that gets pressed too often and at some point it begins to mess with the digitizer connection. It can be dirt. It can just be the cable came lose and needs tightening, it can be wear-out.
whatever it is, it is caused by the end-key being too close to the connector cable.
If you guys only searched for this on the HD2 Forums before posting this Thread hat not been necessary. It is the most well known design flaw of the HD2 and as such well documented and commented here.

This is truth. Save yourself some time and frustration and repair it or get it repaired. It's a great phone.

You didn't get it right or at all:
END key may determine touchscreen failure along the time(being the CAUSE! of this), but the EFFECT is an unusable touchscreen, which cannot be repaired in any other way than replacing it(the touchscreen!!, I mean).
Any other attempt to repair, clean, bend, press, cut or whatever WILL NOT FIX an already faulty touchscreen (even caused by END button excessive or not usage) and who thinks otherwise, no problem with me: SWEET DREAMS!
You sound like my comment hurt you. Sorry if it did. I'm not one hundred percent sure that this issue can be fixed without replacing the screen, yet fairly certain. I've now disassembled two HD2 and couldn't quite find the precise spot where the damage occurred, yet after properly assembling the devices again, one came back alive, the other not. The one which has the screen and buttons not working right is the one that got thrown at me by a kind person. It most likely has physical damage somewhere, although I couldn't locate it. The other one didn't get damage and has screen and buttons work well after complete disassembly and assembly.
Both devices also have different screen types.
I now gave up both devices and am withdrawing myself from the HD2 world. Too many issues with the devices getting old.
