What a STRANGE problem with my buttons and LEDs! Ideas?

Hi guys!
Long time no post!
I hope you can help point me in the right direction.
Two things started happening with my 8525 TyTN, rendering it unusable. I do have a backup one, so it's no panic. But I would LOVE to try to repair this.
Here's what happens!
1 - The two LEDs in front don't work! No green; no blue; no amber. (HOWEVER, When I first replaced the battery after a hard reset, I did see is glow red for a second!)
2 - None of the buttons on the front work! None. Start/End, the D-pad, mail, internet explorer. All dead!
Interestingly enough... the LCD screen is perfect, as is the touch screen.
The unit also works perfectly fine.
I did a Hard Reset.
I am using WM6.0.
I am wondering... PERHAPS there is some kind of ZIF cable that goes from the body to the top panel? MAYBE that came loose?
If you have seen inside your TyTN, is there one cable/ribbon for lights/buttons?
If so, that would explain it!
If there are two cables/ribbons.... one for lights, one for buttons, then the odds of them BOTH falling out are near impossible!
I would LOVE to hear any ideas or thoughts!!!
Thanks as always!!!!!

Hello and welcome to a new phone!
I have a similar problem, mine sometimes gets a white screen and the D-pad buttons rarely work for long.
It is quite possibly a loose ribbon cable.
There is actually a thread here about this issue - just do a search for 'white screen' or similar and you'll find it. It was posted to within the week so shouldn't be far from the top if you browse for it, but I can't remember which Herme's category it was in.
There's even a full guide with pics to pulling your 8525 apart!
Cheers! Oggy. ó¿ó

try a new rom,.

I have the same problem. I thought it was bcs my TyTN fell down once. It started with Iexplorer always popping up when I wanted to do something. I thought the IE button at the top was stuck or something and when I pressed hard on the message button everything was okay. All buttons worked. But after a few days they stopped working and pushing the message button wont work also. And both the red and green call button leds are always shining. It sometimes happens that the dpad works for a second and than nothing.
I used the original wm5 and flashed to 6.1 now, no change tho.

it's not the rom, tried several roms now
for me it's just the call answer button, but this is annoying enough
there are some topics in the hermes section which describe the problems you encounter or even worse problems (the lcd flickering or just giving you a bright shining white) and they all say it is a loose cable connector right under your dpad
some of them opened their tytn (guarante already gone) and put some sort of paper or rubber or sth else on the connector.
other say tighten or loosen the screews worked for them, but none of the solutions seem to be final, it always works for some time.
if you have still guarantee i would try sending back or try somewhere else a repair, that is what i will do with tytn
i hope i do not have to pay for the repair
good luck

Loose screw
I was able to fix this problem after ATT told me that I was out of warrenty and it was going to cost 499.00 for a new phone.
I it turn out it is a loose screw on the inside and to get to it you have to undue 11 screw to get to it. I might be able to fix it for you. I dought you would be able to get into this phone and not hurt any of the other functions.

Hi,
could you advise how you managed to fix it?
Thanks.

button failure and white screen
I have the same problems, if I turn off and on for 3/4 times everything back to normal. But is really annoying because I miss calls.
To me seems a software issue.... I can solve it by turning off the screen does not make sense hardware problems
have a look to this post:
http://forum.xda-developers.com/showthread.php?t=435281
I have still to test the suggestion of schaps advance config version 2.02.1.0.0

Sorry it not a software issue and you can flash a 100 roms and it still won't work. You simply have a bad flex cable and possibly a defective dpad circuit board. You have to crack open the phone to replace it and it has to be carefully done. There are tons of DIY's about opening the phone and replacing the cable. There are even YouTube Videos about it.

Digitizer replacement?

The warranty for my HD is gone and I would probably need to change the touch screen digitizer myself, found these on ebay for ~60€, but does anyone know how to change them? Again, any help would be appreciated!
Originally:
HTC Touch HD, it has been a wonderful phone until now. I have encountered a wierd problem with the touchscreen.
First the touchscreen stopped working completely, after awhile it suddenly started working, at first it recognized some bits and pieces but now it recognizes every touch as normal, except..
It is very inaccurate and the "sum of inaccurity" seems to change depending on where I push the screen, the screen alignment option in settings does not fix this.
I recorded two videos to show this problem better:

Any help would be appreciated on how to fix this!

I have handled it with great care so no big knocks or drops. Ill contact the store about the warranty. Just wondered if theres a way how to simply fix this.
Just noticed, the screen works normally sometimes for one touch, then it goes back to the inaccurate **** :/
Im now guessing that some cable could be loose or something like that?

Have u tried recalibrating the screen? I can't remember exactly where I found it, but its in programs or settings somewhere.

I can tell you from previous experience, HTC does NOT warranty touch screens. You mentioned "a store", so I hope they help you, because HTC will not. >sigh<

Seems a little unfair if they don't seeing as the HD is purely touch screen!

Hmmh, well the store probably sends it to some service center here in Finland that fixes HTC phones.
Indeed sounds very stupid if the warranty doesnt cover the touchscreen.
Perhaps my HD suffered from something else than a broken touchscreen, eg. mainboard or a chip that controls the touch screen. Who knows I'm just hoping it "passes" the warranty :|

Well... Had Hard-SPL on my touch hd and duttys 1.7 rom, so the warranty is gone
Didn't know they were so picky about it, they said it would cost 605€ to repair the screen. So now I should probably start looking for a screen digitizer on ebay and some help on how to change it... Already downloaded the service manual, but there was nothing on how to change the digitizer, could anyone here show me some light to this? Thanks.

I have dismantle my HD to see if there's any way to change only the screen (it's broken)
There's no way, as far as I saw. You have to replace LCD, tourch screen and screen. It's one piece and there's no way easy way to open it without break it.
You can find all of them for about 200E.

Another sad story // hopefully with a good ending
I kinda have the same problem as Viba and others. Sorry for the looong post. But decided to describe in more details my experience up to now, and hope you can help as well.
All of a sudden, I started having problems with the touch screen of the Touch HD. I started noticing that whenever I touched the Touchflo buttons, the phone vibrated. Soon I came to realize the if I touched in some spot, the phone recognized that I was touching lower, to the point that it could not recognize touches in the taskbar, for instance.
The united has 2 or 3 months max. It had some falls before and I do not really know who (or which one) was the culprit.
Tried this as fix: re-alignment, hardresets, Official ROM upgrade. Then I started reading and understanding that the problem was probably the digitizer ("nice to meet you").
I live in Brazil and the Touch HD is not expected be released here any time soon. So the few HTC service centers do not know how to fix it and do not have parts for it. And also, I bought mine from an auction site by some user who bought it abroad, with no warranty whatsoever. I am left alone in this.
I was very frustrated and eager to get my device running again. So I started looking for a new digitizer and also the tools to open my phone. The digitizer (just the digitizer, not the LCD screen) I ordered from an ebay shop in Hong Kong on Monday and is expected to still arrive sometime in this century (IF Brazilian port authorities do not mess up). The tools arrived yesterday.
I downloaded the service manual and said to myself, let's see if the digitizer problem is maybe due to a loose flat cable. Got to work and carefully disassembled the device as per the service manual. (I have to say that, although I try to be carefull, I always scratch, bend or mess something up when I do jobs like these. So I was afraid of cracking some plastic or worse and actually did some.)
Up to where the service manual show, it went incredibly very well. But that's the problem. The service manual guides you to disassemble the unit up to the point where you are with the bezel, LCD and digitizer in one piece.
But hey! I saw zillions of internet shops selling the bezel (actually, the hole housing, but with no LCD), the digitizer or other parts separately! What is going on?
So I started trying to unmount the bezel, LCD and digitizer. Tried several things. It got really late. I was impactient. So I tried splitting the digitizer from the LCD, by inserting a hard plastic aluminium tip between the digitizer and the housing. A very thin plastic kind of tape came out (at lest part of it). So I tried doing it more. No success. And then I put a very thin screwdriver between then (just enough to get an ulgy bent it the plastic housing).
When I had played enough with that puzzle, I gave up and began mounting everything back. The good part is that I was able to get everything back and the phone is working. Well, except for the digitizer.
First thing I did was to kidnap the wife's Nokia E71 I bought her last month and she is not using yet (she couldn't learn to use yet; well, she hasn't even tried it), because I have to have mobile access to my emails.
And I really started now to consider other alternatives. Will some user like me EVER be able to change just the digitizer? Is it even possible? If it is, I would like to give it at least another shot.
But I am also afraid that it could be another part which is in failure. I just don't want to spend more $$$$ in this. It would be better to buy another phone (and maybe not a complete touchscreen - gosh, I miss my Tytn II). I so regret being a gadget freak and not waiting a release in my country.
Shoud I send my phone abroad for a service center repair? My sister lives in Dubai and she may be able to help.
Should I give up my unit and seel the used parts in ebay?
Hope to hear your suggestions. Thanks anyway.

before doing this what about removing hspl and reflashing back a stock rom
change shop and you might, and i say MIGHT, be lucky
much better than screwing up the machine

I have already tried with 3 custom roms and 2 original SPL:s with two original roms.
The Finnish law allows me to get my HD replaced if I could prove that the custom rom didn't brake the digitizer. Already sent some emails to the local repairstation for HTC phones here in Finland, lets see...

I run a repair center (US). I have not gotten curious enough to take mine apart, but if someone has a dead one to experiment with, PM me.

Broken digitizer glass
I have the same problem with the digitizer glass being broken. I have had the back off the phone and stripped it back as far as I dare, but the service manual just doesn't tell you how to replace the digitizer and glass only. Checked out youtube where there are many videos with instructions on how to replace the screens and digitizers on lots of different phones as well as the iphone, just nothing on the Blackstone yet.
Any one else found a solution or decent instructions?

Today I disassembled my HD too, found a loose screen wire but nothing else. Even when I attached it properly the screen didn't work.
Has anyone found out how to change the digitizer?

some info
Hello,
I am also have HTC Touch HD, and I am also thinking about replacement of touch screen and housing because of scratches. Here instruction in Russian
http://www.pdacenter.ru/razborka/htc-touch-hd/
step 24 is not shown on the picture, but there is mentioned that in order to replace screen you should push it forward from back side of the screen; also mentioned that screen is fixed with double sided tape (probably it is fixed to the touch screen)
Also, did you try to use any polish to remove minor scratches on the touch screen? HTC Touch HS has resistive screen and probably may be polished (in contrast to capacitive touch screen that has some coating).
All the best

Also, about this problem see
http://forum.xda-developers.com/showthread.php?p=3911326

You guys should be smarter! If you want to warranty exchange it, flash the normal SPL again and flash a stock rom!

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.

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.

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.

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.

[Q] Wandering screen alignment??

Hi all,
My trusty blackstone has begin letting me down and I don't know if flashing a new rom will help, or if it is something physical that is breaking / broken. I'm using the Stonehenge ROM with CHT and everything has been fine for months.
Recently the touch screen allignment just seems to 'wander' sometimes just a little, other times quite a lot (so much that using the fake hardware buttons at the bottom of the phone, brings up the start menu). This means that intermittently I cannot answer calls, and typing a message on the SIP is an absolute nightmare!
The start menu icons do not seem to be as affected as the home screen and CHT, and I can quite easily get to the phone settings and recalibrate the screen - this will help for a short while but the alignment drifts again.
Restarting the phone has a temporary positive effect but it doesn't last.
Anyone else experienced this?

I have exactly the same problem.
Dissembled the whole device, blown some hot air but didn't help. Seems it's a HW fault. But I have a doubt whether the problem is in digitizer or in control board.

It's definitely one of the more frustrating problems that I've ever had with the phone.
I might try flash a new ROM then give up if that doesn't work. At least I won't be tempted to disassemble as it has already been tried, tbh I'd have just tried the tin of compressed air too, I don't trust my soldering skills for tiny electronics.
It is getting progressively worse, the touch area of the screen has slipped so low now that I can't use half the screen.

[Q] HD2 Screen Trouble, Looking for an answer to buy the right part

Greets all,
I know probably this is the wrong section but I thought I would get a quicker response to my dilema. I was testing out my rom on my Test HD2 phone (I have two of them) and this one has the infamous end key issue, and tested my patience, so I read that if you use a very small flathead screw driver and push a certain place, you can get it to unstick, being that I tried all my methods that usually worked, I decide to try, well, the screwdriver slipped under the button part between the end key and the back key and screwed up my screen where I have all funny colors all over. So I was wondering if any could tell me if this is a LCD problem or a digitizer problem. There is no running liquid on the screen. The screenshot below is exactly what my screen looks like, and I want to buy the replacement, but I dont want to buy the wrong part and waste money, so can someone please let me know what it is that I have to replace? Thanks!

Its definetly an LCD issue, anyways not a major issue, as long as you can dismantle the phone and clear up the area btw the LCD and Keypad, i guess it should be back to normal

When you say Clear up the area, mind clarifying what that means? I can dismantle the phone, at this point it would probably be cheaper then sending for repair especially that its most likely out of warranty anyway.
I'm pretty much under the impression I am going to need to buy a lcd/digitizer combo to fix this. Unless I dont have to, cause like I said there is no bleeding and the phone works fine (minus the touchscreen issue caused by the end key) I can navigate thru the phone using droid explorers Screencast.

well what i intened to say was that there could be particles of dust or debris that is causing the LCD ribbon to come out a little, Coz i had a similar issue with "Dead touchscreen workin hard press end key " , later when i dismantled the phone and put it back again my screen looked exactly like yours, all i had to do was open it again and fix the LCD flex to the Main board properly thats all.
on a side note:
Well the touchscreen issue eventualy died all together, and i now have a replaced LCD from HTC and the screen is dull
