Touchscreen doesn't work when slider open

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.

well i got the same problem as u have/had... But i also need to align my phone like ten times a day, because its always out of alignment... I think i got to get back to the phoneshop to fix(replace) my phone. I do have the touch dual for 6 months now.

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.

Sliding Keyboard Issue

So today my Titan started acting up. When I slide the keyboard out the screen freezes. I can still type by nothing will show up on the screen until I close the keyboard.
Also If I hold the keyboard halfway slid out the phone will work normally(but can't type with half the keys), however once I go past a certain point the screen freezes?
Hardware or software issue? I'm debating a reflash.
I can see these thin metal wires inbetween the keyboard and screen when I slide it out, I wonder if it has something do do with these.

Well the reflash didn't work. I took the phone apart and still can't figure out the issue. Seems like it might be with one of the cables connecting to the LCD screen.

I have literally the same EXACT problem. Have you gone to WM 6.5 beta yet by any chance? I started having the problem and numerous others when I went to 6.5. Idk, if you figure it out please tell me. I will be trying to fix the problem too.

Well, I have found the reason why mine wasn't working properly. My flex cable attached to the screen that goes to the actually phone motherboard is ripped. Would anyone happen to have one??? I can't find any on the internet. I have searched everywhere. Please help. Thank you!

HTC HD2 Screen Unresponsive

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.

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.

Unresponsive touch screen :(

The top part of my phone does not respond to touch anymore... it is impossible to bring down the notification bar... and once in a while the whole screen goes unresponsive.. tried factory reset but still the same problem..

am having the same problem since 2 days back
after reading some of the posts i found that the Digitizer For HTC G6 Legend A6363 should be replaced with new one i ordered mine from ebay
ebay.com/sch/i.html?_from=R40&_trksid=p5039.m570.l1313&_nkw=Digitizer+For+HTC+G6+Legend+A6363&_sacat=See-All-Categories
waiting for the item to be delivered

I've also got a touchscreen issue: the area of the notification power widgets is unresponsive... the rest of the screen works fine, but I don't know for how long :/

Do you have widgetlocker, by any chance ?
Or a lockscreen replacement which disable the notification bar during the "slide to unlock" state ?

I didn't know there was such thing as widgetlocker. I use CM7 latest nightly, never seen that thing.

I also facing this problem from last 2 weeks and i also think this is digitizer problem. If anyone else found the solution else changing the digitizer, then please post.
This is beautiful phone but htc added a poor quality things in it, due to which many users facing such problems.

Nah.. I dont think its because of widget locker.. its the digitizer..

well that's a shame, gotta buy a new digitizer on ebay after just over 1 year of use...

I know.. this sucks... Im planning to upgrade though.. Any of u guys have any suggestion?

Depends on your carrier if you want suggestions for an upgrade.
...but that would drive the post off-topic.

I have the same problem. my screen doesnt work anymore because some water got in from the grill above the screen :S
should I try to take apart and dry off or shall I buy a new digitizer directly?

I think it may be a good idea to try disconnecting your digitizer and reconnect it as it just might be helping. I did it on my girlfriends legend and it has been working perfectly ever since. Maybe a good idea to at least try that before buying a new one. So i guess it could be in the connector to? At least this worked for me.

My touch screen dosent work at times. but after rebooting the phone the problem becomes solved. But the problem comes again after a week or so. Any suggestions guys??

I also have this problem, but if I wait a couple of minutes the touchscreen
becomes responsive again. Half of the screen works when it's unresponsive (right half of the notification bar and down). It's quite annoying but I cannot afford a new phone at the moment.
I'm also wondering if this might be temperature related, this problem reoccurred very often during the summer but stopped during the winter. But now (spring) it's back again.

My problem got worse and the phone became totally unresponsive, changed it, got a new phone.

exact same problem here, mine works when it feels like working, totally random, I simply can't understand why, I doubt it's the temperature... I think its in the device theres something wrong, I smack it numerous time and it works right after a big smack on the screen, or rub your whole hands on the screen, also, the angle you are holding the phone affects this problem, if none of these work, a phone restart always makes it work at the beginning. Oh boy did my phone took and taking much beating... oh well, I wish I could permanatly fixed the problem here, as I was thinking of handing the phone to my brother when I upgrade, I'm using CM 6.1.

I still recommend the same thing that i posted earlier here, her screen still works perfect.

I had the same problem few months ago. The problem is with the touch digitizer. I bought a digitizer on ebay and replaced it myself. After that my phone has been working fine. Its not that hard to replace it if you have a small knowledge about hardware.

I use to get that unresponsive screen issue only in the summertime, plus it gets worse if I add humidity (read: sweat). I just need to give it some time then to dry off/ cool down outside my pocket, and it's all fine again.

[Resolved] Touchscreen doesn't wake up properly

Hey y'all,
I am having a weird problem. I have an HD2 wich worked great. Now after some time I am having a problem with the phone waking up. When it's active and unlocked, the touchscreeen works great, but when I turn off the screen and turn it back on, it won't let me unlock it. The touch screen just doesn't seem to work any more.
So I thought maybe relfashing could help. Said and done - reflashed Android > didn't work. Wiped, flashed WP7 > didn't work.
After some time and trying 3457 times, it works sometimes and once it is unlocked everything works well. But it's unusable this way.
Any ideas?
Thanks in advance,
JR

I had this problem yesterday. I bought my phone second hand, it had a brandnew touchscreen, the previous owner dropped it.
after 3 months (yesterday) it started woring really bad. 8/10 times it wouldnt work.
I got my hands on a HD2 which was bricked (epic fail) for 10 bucks and swapped my mainboard. it works flawlessy again. Im guessing the replaced digitizer was a cheap knockoff from China.

My friend's phone has the same issue. Touchscreen works if you wake up the phone by back button, but it does not if you wake up with power button. Did you try that?
The most strange thing is, it is the same when on windows or android, as you said.

Hey there.
After some searching I found out, that the digitizer is messed up. The thricky thing is: The digitizer hardware is located right beneath the power button. This is what is causing the problem (the power button was messed up a little also). So if you are experiencing the same issue - try pushing the power button a little harder. That might make you able to wake up the phone.
I would have to renew the digitizer, wich is a real pain and a lot of work. You'll get a new HD2 for around 130€ and the digitizer costs about 60€ I guess. Plus all the work and the risk of f***king it.
SO - my choice will be a new one. HD2 is just a great phone because of it's community!

or get a bricked on for less like I did. Swapping the mainboard is really easy if you take the time and use the iFixit repair guide. I used a hair dryer to ease up the internals by heating it up and with a suctioncup I pulled the internals right out of the shell.
the copper sticker is a real pain in the ass though... But its doable.
You'll need a T5 torx screwdriver.
Oh and I love the HD2 community no doubt about it

I have the same problem, you think it gets resolved by buying a new digitizer? I was told the problem is not that main board but only the digitizer so not worth the hassle of getting a bricked phone I assume.

A nonresponding digitizer can be caused by many things. I´ve heard of the end key messing with the touchscreen controller and vice versa.
I had a replacement digitizer on my HD2, it stopped working and now I have a genuine digitizer.
The genuine screen is just much much much better. It just feels much better. It´s more ´slick´. And less grime attracting.
Look in the general section for people who have bricked their HD2 and PM them and offer them money

Hey guys i have the same problem u think its the digitizer not the flexible ribbon?
