I did a DIY digitizer replacement a month or so ago, and its been working great up until a few days ago. Now, when I go to touch one of the soft buttons or type on the keyboard, the phone "flips out" and starts registering inputs in all random spots, sometimes getting stuck on that spot. I am totally stumped.
I double checked and all the ribbon cables are seated and such, and tried flashing over to Modaco rom from Cyanogen (thinking it might be software)... no luck. Can't even replicate it consistently, it seems to have a mind of its own.
Any thoughts as to what is going on?
Well I know that it has been an issue for some people and the general idea is that if you push the power button and put the screen to sleep and then wake it back up 20 seconds or so later it will work again. I have to say to also wipe your screen clean as well, build up on the screen can cause wonky behavior as well. Good luck.

this sounds exactly like the glitch that all nexus ones have, stock ROM. just lock then unlock the screen and it fixes itself.
the word is that it will be fixed with the 2.2 update. fingers crossed.
I thought it was that issue I read as well, but the power button glitch-fix everyone speaks of doesn't work.
I actually used my pry-tools to unseat the digitizer from the rest of the phone and kinda let it dangle, and 90% of the issues disappeared.
I am wondering if it might be the digitizer pressing up against the metal backing thats causing it to ground out and cause these issues, since the original phone was held in by a foam-type adhesive which I don't have on it now.
that's very possible. the power button resets my glitch 100% of the time. so sounds like something else is going on with yours.

I don't think its the famous touchscreen issue that we've heard because it was reported to register a click few centimeters below the touch point. Here in this case, the guy says that it randomly registers clicks at different spots.

I hope that reboot fixes this problem....
I've given up on the task for now, went back to my iPhone 2G till I can figure this out... its definitely not software though... and the digitizer still registers accurately when I don't have it seated into the phone...
No issues here on cyanogen 5. 0. 6 I love this Rom and have 0, yes I said it zero issues..... running solid for almost a month.... sorry ya have them issues I hope ya get em figured out...
As others says, just a quick lock & unlock fixes this. No need to wait 20 secs, I do it right away. Power, power, slide to unlock and I'm back in business.
For me I'd say it happens maybe a couple times a week? What about other people?
On stock it happened like once a week.... for me
none on custom so far after 3 weeks
yeah a couple times a week is it for me too. I wonder if view identified the issue and fixed it in the update. I'm sure some Google employees experience the bug.
my nexus one went bad (the power button was shot) and I sent it in on tuesday. well yesterday I had a notice from fedex on my door because of a delivery attempt. today I received my nexus one . I had the modified bootloader and custom rom and it returned with a locked bootloader and new screen (i think)
2 day turn around time
HTC thank you!
whats the cost?

Also how long have you had your nexus one before the power button went shot?
Mine crapped out on me. They sent another overnight great service.
had my nexus since the day it dropped. and it cost $28 lol
Wow, that's great!
What number did you call at HTC? Also, did they ask you about the bootloader being locked or not? Also, did they mention if they have the right to charge you back if they find out your bootloader has been unlocked?
Awesome.
It's my understanding that if it is a hardware issue having nothing to do with the OS/bootloader then they'll help you out, even if you're rooted/unlocked.
Mine started looking like it was on its way out, then I flashed CM6 - problem solved - 0 day turn around. Not sure I was having the same issue as you but that power button sure was acting strange. At first I thought it was hardware but I ruled that out because long pressing it worked every time, even if the menu showed up and the screen shut off before I could make a selection, it was I obvious that the button itself definitely worked. Then I read a feature of CMmod that read "debounce power button", tried that rom, been a okay ever since - not one hiccup

This could definitely help when the button is getting a little flaky (dirty/worn) ... the 'bounce' could cause the phone to wake up and go right back to sleep so fast that it looks like nothing happened.
A great feature to add ... but, then again, most of the stuff Cyanogen (and the rest) put in is pretty smart.
I enable the trackball wake up in the CM mod to reduce ware on the power switch.
Hey my lovely XDA-ers, I'm really hoping for some magic here...
Yesterday my HD2 digitizer just stopped working... the Touchscreen will not respond to any inputs. It was bitterly cold outside so I was half hoping that an overnight stay in a warm room would help, but no avail...
The thing is, on one in every 5 restarts, I get a small amount of life from it. One one in 15 restarts, I get full use. So there's still life in there.
I could understand if it broke because I dropped the phone/squashed it, but at the time I was just playing Robo Defence, completely normal use, when all of a sudden it stopped responding.
I've uploaded a video, which shows how, occasionally, the bottom fifth of the screen works. However, as shown, when I'm using the top half of the screen, the digitizer appears to be receiving input from the bottom of the screen, as though I'm trying to perform a multi-touch action. For this reason I'm hoping there still be some way to rescue the phone without an expensive repair job. I bought it in March from XDA Marketplace, and it's served me faithfully since, but because of that I do not think I have the manufacturer's guarentee, or insurance
I've hard-reset, I've reflashed my ROM, I've tried in both WM and Android (my usual OS at the moment), I've reflashed over WM ROMs, and the problem stays the same... (also read all related threads!)
Sorry for inverted nature of vid!
So does anyone have any suggestions to try? Otherwise I might go through a £130 repair service on htcrepairs.co.uk - they do not show up on a forum search so I was wondering if anyone had used their service before?
Thanks all, appreciate any ideas.

Very odd indeed. I don't have a solution for your problem, but a suggestion. It is a long shot, but might help.
Whenever i had similar problems with my Wizard (i know, kind of old but one of the best older devices every made by HTC), i opened it and cleaned it from the inside and checked all the connections of keyboard, touchscreen, etc. to the mainboard. Sometimes it helped...
In the end, if you buy the replacement kit, you anyway have to open the HD2, so why not try this in prior to buying the kit...
A lot of people seem to have this problem. There's a lot of information on it here. Do a search. But the short answer is its a hardware problem. If your phone is still under warranty send it back. I think HTC will fix it for free if It's less than a year old. But try your carrier first.
Sent from my HTC HD2 using XDA App
BAD NEWS...
i had EXACTLY this happen to me. eventually it totally stopped responding. Only option is to replace the digitizer.
GOOD NEWS..
After a month of searching, I found a really good guy to do it. www.iexpertstudio.com . The owner is VINCE. you can email him on his site. He charged $110 including mailing it back to me. He replaced the LCD and digitizer and sent it back. All works perfectly now.
I see you are in the UK so dont know if it makes sense to send it to the US. Alternative is to go on ebay and buy the screen/digitizer and replace it yourself.
(BTW normally i would have chucked the device, but even after 1 year I still dont think there is as versatile a device as the HD2. Had the DHD been 3G useable in the US I would have bought one.)
Thanks for the feedback guys, I've been doing some investigation my end (and you're right, there are similar threads on here, but none which had a "half-screen working" problem.)
I've narrowed the culprit down to my "Back" button. It's somehow exerting pressure on the screen, leading to either a non-responsive digitizer or an input at the bottom of the screen.
I might add this to an entry in the "ANDROID KILLS YOUR BUTTONS" thread
My choice is to live manually with it, or get the company mentioned in the first post to give it a good clean, but whether it's worth £80 just yet is a question for me.
Anyway, thanks for your input, guess this thread will close, but to any readers in future, if your screen seems to die, see if it's pressure on the screen caused by the buttons!
I can totally support your reasoning.
I haven't had any problems whatsoever with the touchscreen in almost a year of honoured career of this phone, while this morning I was trying to unlock it with no success (nothing special happened, I even used it 10 minutes this morning already). At first I thought it was the usual "sleepy" behaviour of the screen right after waking up, butafter sliding down the hdmini style unlocker at least 10 times with no effect I really started freaking out :O
I have longpress endkey set on instant reboot, and after that it seemed working... just not for too long.
To cut to the chase, what in my opinion supports your idea of hardware buttons interfering is:
sometimes, as I have LMT installed, with the tap&hold option enabled, swiping with just one finger triggered double swype instead (as if the screen detected a second, firm press on the screen elsewhere even if I sure as heck was swyping with one finger)
using mymobiler didn't work as well; if it was a hardware touchscreen problem, mymobiler should work, as it simulates touches, so it will just do its job even if the touchscreen is totally dead... while, IF the hardware touchscreen detected a firm press somewhere, mymobiler wasn't able to actively simulate another press
repeatedly pressing on the end key (which seems to be the culprit in my case) apparently solves the problem, as I can use the touchscreen again; also, a prolonged cycle of hibernating with end key, waking with end key, swyping down the hdmini lock (repeat at libitum) seemed to work, as if I dislodged something by activating the button so often
What I don't understand anyway is: HOW can a button pressing on the digitizer be exerting a touch action? If this was a resistive screen, I'd understand, but it's capacitive, and not even capacitive pens are so good as fingers in activating the touch. The buttons are just plastic with a metal contact underneath, and this metal contact shoudl by no means be anywhere near the digitizer.
Bah.
I know I have 2 years warranty on this device, but being far from my phone during the warranty processing gives me the creeps, so I'll just go on using it and pray this to be the defaillance of one sunday morning not to be seen again... after several soft resets (and fantasizing about a new rom flash, which I need anyway for other reasons) the problem seems to have settled by delicately bashing on the end key. The unlock slider is responsive after every wake up now... FOR now.
Praying...
My screen also died. So the only thing I have to do is press on the end key for a couple of times to make it work again?
lol, that's ONE possibility.
Just saying, in my case it worked, and still does since it happened once more this evening, so it's definitely got something to do with the hardware keys messing around (and hopefully dislodging themself for good, or I'll have to send it back for servicing), anyway in your case it could also be a dead digitizer, so no go
let's put all this about touch screen in 1 sticky thread pls.
I've been living for the problem for about three weeks now. It's never got worse, but never got better. It's a livable situation so for the moment I'll deal with it. I might check with HT about warranty, but it's not yet bothersom enough to make me want to flash back to stock, send it off etc. etc.

Actually, I don't like having paid good money for a defective phone, but being without HD2 for up to a couple of weeks to one month (maybe? have no idea how fast HTC servicing is) is troublesome. I may buy for a deal a blue angel as a spare, yet, no GPS...
The most problematic event is if you get the "stuck" screen during a call.
In my case, it's the end key that messes it up; if the screen's dead, pressing twice the end key, firmly enough (once for screen off, then again for screen back on) wakes up the screen, and apparently, during a ringing incoming call, you can press the hardware end key without rejecting it, so it's a viable option (not taking into consideration the fact that trying to wake up the screen takes time, and the caller may give up after a while if you're not fast enough).
But if for any reason the screen gets stuck while the call is connected, I am stuck too, as to wake it up I should press the end key thus hanging on the other party.
Sad story.
EDIT: forget what I wrote, pressing end key while phone is ringing WILL reject the call. I tried it before during a real incoming call and apparently it didn't do it, but now it just did.
I also have a HD with a dead screen....
Only thing here is I have sent it back twice already to TelSuck here in Australia only to have it returned after the tech has wiped it over and reflashed it for me... What helpful little imps they are!

Its drivin me nuts sending it away for 3 weeks at a time to have someone with just enough grey matter to be able to wield a screwdriver tell me nothing is wrong.
Happy to try any suggestions!
@insinr8
this thread is just for half-dead screens where the screen sometimes actually works. Unless you can resurrect it by firmly pressing on the hardware keys, but if it's dead on a regular basis, then it's not our same problem I'm afraid :-(
@OP
while having an "attack", did you try plugging out the microsd to see if it magically solved the problem?
I mean, if it did, it would still be a hardware problem related to the microsd slot, since there is no point for a faulty microsd to mess up the touchscreen, and let it work from time to time

I will try that - it seems to happen more frequently when plugged in and charging, and now more buttons seem to be the cause/fix (e.g. now the home-button, or when I am on home-screens the phone will swipe "left", whereas before it would swipe "right". I'll keep playing.
I may check out HTC as I reckon my warranty, if I have one, will run out soon... Will still wait til after Xmas as I need my toy for the boring bits of Xmas!
I'm having same trouble now whit my phone except problems started mouth ago. After some period I again power up my phone and suddenly everything worked perfectly. Unfortunately this last only for two days and then exactly same problems happened, partially function screen.
As far as I know only good solution is replacing digitizer... I already ordered one for me.
exactly the same problem for me.. I sent it back with warranty yesterday

Ditto.
Actually, my warranty lasts two years, which means until 2012, anyway I cannot stand risking to lose calls because the screen dies on me in the wrong moment, and the only way to wake it up is pressing the endkey (which by the way is the only "cure", and apparently never the cause).
I will be uploading a video on youtube regarding this, also to show it to the guys at the HTC support who will be asking me to hard reset and reflash until annoyed to death (as if that will solve anything)
Bump
This is the video that I just uploaded to youtube:
http://www.youtube.com/watch?v=C3-PNYwpYeI
EDIT: One day after, the problem has become way more frequent, 1 out of three times I wake up the phone, diugitizer is dead and I need the " on the end key to make it work
Uploaded another video on youtube with problem showing on vanilla lockscreen so HTC support doesn't try and tell me it's CHT lockscreen's fault
Last bump.
Screen has ben promoted from "hardware key problem" to "permanent death".
Now I can use the phone with mymobiler, but I can't anymore with touch, I seem to not be able even to wake it up even by pressing on end key
Re-flashing last official rom upgrade now to see if anything changes... yeah,sure
Ouch - good luck, hope mine doesn't go that way...
I got up this morning, grabbed my tablet, switched it on and found that no matter what, it wouldn't respond to touch input.
Hoping I could sort of "kick it" by using a keyboard I plugged one in and while that worked fine, it didn't unstick the digitizer.
Had to reboot.
Anyone else seen this?
I've had this happen once or twice, and as you mentioned the only way to get it to respond was by a reboot.
oooooo.... never happened to me for the full 6 day since i have this tab i suggest you turn then for replacement....
just remembered something are you guys by any chance use screen filter? that causes touch problems in some spots....
I'm using it on my phone but but not the iconia
its has happen twice in the last two days. Usually when the tab is left for a while hours. You're right the only way to unlock is to reboot.

Na, I'm not using a screen filter. It happened twice in the first couple of days of owning it and hasn't happened for the last couple of weeks. I've had the same thing happen on the Desire HD a couple of times as well. It doesn't happen very often so I'm not overly concerned.
Jup, sometimes the screen doesn't respond. I found that if you rotate it (even with the lock on) and then turn on the device the screen wants to rotate and will then be unresponsive. Reboot and all is fine. Seems like a software bug to me.
Just in case you haven't done so, remove the sticker on the right border. It has a metallic back and interferes with the screen. I had that happen on a display model at BB twice withing 10 minutes. Once I removed it, no more problems. And I haven't had any problems with my purchased one.
A friend of mine bought one online and complained about the same thing. I told him to remove the sticker and the issue went away.
the sticker on mine was removed in the first five minutes. haven't had the problem again yet. hope it was a fluke
I don't see any threads about this. I bought the 16 GB c70 model, and sometimes it will, in the middle of using it, just shut the screen off. Sometimes it will come right back on, and sometimes I have to push the power button. Is this an actual issue, or should I not worry about it. Other than that, the only other issue I have random blue lines will *occasionally*(very, very infrequently) show up for a half sec or sec and then disappear. I'm sure if that is a problem, it's the GPU, because it reminds me of something I have seen before. I can't replicate either issue like others can with the "flickering" thing. And I didn't have issues with the screen off issue until I put it in a smartcase, but I can't definitively say it is, or isn't, a cause. Just looking for some advice as to whether I am being picky, like those with the screen flicker, or is it potentially an actual issue in which I should return it within my 14 day return window.
I think I had the same problem
And when I turned my brightness right down the backlight would go off
If you're trying that keep your finger on the slider so you can turn it back up
I took mine back and got a new one, don't have that problem so far

Here's the screen issue I'm having. But the model in staples also had the same issue, so I don't necessarily return it for this one unless it is something that will cause greater issues in the long run.

Markj, I appreciate the response, I may do that. I'm going to give it another few days, as I have until 7 days after Tuesday to return it. But it's not looking promising at this point

This is issue I have been having that I described above. It got so bad today that I had time to take a video of the issue.
