Touch Screen Dies after 5mins of use

Hi all.
Just got a JasJam about 2 weeks ago.
I am have a problem with the touch screen.
After about 5 mins of use the touch screen slowly gets more and more unresponsive untill it stops working.
If i remove the battery and let the phone sit for a couple of minutes then restart it the touch screen would start working again. But for only 5 mins.
Is this what everyone is refering to as problems with Screen Allignment or do i have a bigger problem.
Does anyone have any suggestions on how to fix this problem.
Thanks
Travis

Personally i would do i hard reset and not install any additional software to see if you have the same problem. If yes, then its hardware problem and needs to be sent in for repair. If not, then install your programs back one by one to find the culprit.
S.K.
EDIT: Ensure you back up your data before performing a hard reset. You will lose all information stored on the phone.

Silent_Killa's advice is what I would do. Might try uninstalling apps one by one first??
This is NOT the screen alignment issue - I don't think. It depends if the screen responsiveness going off is actually at the point at which you tap the screen is not matching where the screen responds?? In other words it does respond but not at the location you tap. If this is happening then it is the SA issue, but if the screen does not respond in any way to taps then I doubt it's the SA problem - though could well be a digitizer issue.
I have not searched, but a week or two weeks ago an identical problem was posted by someone else.
If a hard reset does not cure this I would suggest a return as soon as possible.

Hey guys.
Yea i trided the whole hard rest thing and it still did the same problem.
The screen works fine but it is just the tapping part that gets screwed up.
All my hardware buttons work ok so i can still use the phone. I just can't use the touch screen.
Do you really thing an application could do this sort of thing.
The main ones i use are -
SPB Diary
SPB Pocket Plus
Spb Weather
Pocket Informant
Are these know to cause any problems.
I will try one more time and not install any apps.
Oh well 2 weeks old and it's off for repair.
Thanks for your help.

BUT surely you tried it for an hour or two before installing anything!!?? And if working then only one application at a time?
No I don't think any of those apps. are the cause of the problem.
You still have not given full details about whether the screen is completely unresponsive or misaligned.
Either way if it's under warranty and hard reset does not cure it, get it returned cos this is not some little software fault.

Yes, it was me (I think), I had this problem too. It was only when the keyboard was slided and locked opened. Button would respond but screen would freeze and the start menu, sometimes, would pop up as an extra.
I had to give it back ...

YEP that is exactly what mine does sometimes. After i open the keyboard the start button would start to pop open and close.
How did you get on. Did they tell you what the problem was.
Cheers.

Sorry, about that.
Full Details-
Screen has no problems with SA. After about 5 mins the screen slowly becomes more unresponsibe. IE i would have to tap the start button several times for it to work. When it finially pops open it just closes again almost straight away.
Not long after this the screen will become totally unresponsive, howver all hardware buttons will still work.
I am going to try a hard reset tonight.
I will let you konw.
Thanks again.

Well it is deffinitly my phone.
The screen wasn't working as per normal.
I hard reset my phone. When it rebooted and got to the "tap the screen to continue" bit. Guess what it didn't work.
I taped the screen several time but no go. The screen was dead.
I will have to send it back to the shop.
Cheers.

wiki update
I took the freedom to update the wiki on this issue :
http://wiki.xda-developers.com/index.php?pagename=Hermes_Problems
well, my device was a second hand but the seller was as so kind as to take it back... nothing for chirstmas this year .
still... happy new year to everybody !

JasJam screen responds to "ghost" taps!
The touch screen on my JasJam responds to continuous taps even when I don't tap it. When the keyboard is slid out, the start menu keeps on popping as if the start button on screen is being tapped. When keyboard is slid inside (device is closed), the device behaves as if the OK button (the "X" on top right) is being tapped continuously. Due to this, I can't open any program. (As soon as a program is opened, the "X" button on top right is automatically clicked and I reach Home screen again!
I uploaded a video about this mal-functioning of device:
http://www.youtube.com/watch?v=YWAyRLQ01oo
I have already:
1. Alligned screen
2. Hard reset device (Left and Right softkeys + Reset button)
3. Updated ROM and hard reset device
but of no use! Please help.

Read that
it's a hw issue, had to get a replacement ...

Same problem
I seem to be having the exact same problem. When I first got it, I was able to use the phone for a couple of weeks, then all of the sudden, the screen stoped responding, but all the buttons worked. I did a hard reset, and it worked for a little while, then when bad again. At first I thought it was related to ActiveSync because it would always go bad immediately after syncing. However, even when I don't sync after a hard reset it eventually goes bad again. Today I just got it back from manufacturer - they couldn't reproduce the problem. It worked all day. Then I synced. Stupid me. Its not responding again.

There's no way out. Get a replacement.
I'm hoping that my replaced device doesn't have same issue.

same problem
I have the same exact problem. I sent back the Phone to Cingular / HTC, and they "repaired" it under warranty. I got the phone bac, and after a day's use, it went back to its old state.
Since I got this on ebay (BIG mistake), even though it was new, its having this problem.
So far i am not at ALL impressed with the 8525. Seems to me like its laden with hardware issues.
Can someone please offer insight as to what I can do?

Sorry to hear that! I had actually purchased i-mate JasJAM from Dubai. i-mate has just one service center in USA (PocketPCTechs in CA). They provided amazingly great customer service and replaced the main board. So far the problem hasn't repeated.

Hey, I am having the same problem as well. Bought my phone on December 06 from eBay seller too. Big mistake as HTC will tell you sorry your warranty is void if you did not purchase the device from the carrier (even though it was new.) I am curious how you were able to get it repaired under warranty since you too bought yours from a third party.
I did the credit card trick and it worked flawlessly for about two months and just yesterday I am back to the same problem. After today doing the credit card trick numerous times I finally got the touch screen working now but who knows for how long this time.
BTW my serial number is in the HT642Fxxxxxx if anyone else that has this problem wants to compare and post theirs.

Facing the same problems...
... I've been thinking about repalcing the display and the touchscreen. But now, considering that it is a HW issue, I can only replace these two things. If the bug is in the module above the screen (statur leds and camera) or related to the wireing at the back of the screen, it won't get rid of the problem. On the other hand, if it is a problem with the screen getting too hot, then I'm on the right track...
Has anyone tried this yet?
I'll try to call HTC on monday, maybe they know where the bug is.

is there any solution to "screen can't switch on"?

at the begining , my HD is fine.
But , after 2month , the phone has some rotation problem( it doesn;t matter, as you can solve it by pressing the on/off buttom )
But now, the phone's screen can't switch on, when i touch the four buttom on the surface of phone, it still vibrate..just i can't switch on the screen"
i have already tried all the things like take out the battery, press the reset buttom... the problem still occur,
Screen can sometime turn on luckily~
but, if the phone's screen is switched off for a while, the problem still occur..
can any professional heal my phone?

Obvious questions: Have you tried a hard reset?, Diff rom? Have you loaded up anything weird that mighta casued issues? If it will do a hard reset then do it. Start from scratch. If it works then be mindful of what you reload it with. If that doesn't get it, try a diff rom. At this point you got nothing to lose. Will it go into bootloader mode?
Battery comes to mind also. Have you run it down to nothing? Sometimes that will affect the charging capabilities. When the screen is dark can you still hear sound? Def do the HR.

My suggestion would be, to give the HD to your reseller and get it fixed.
I have had the same problem, and as my HD also didn't connect to my PC anymore, I send it in, and got a brand new one, because they couldn't fix it. Make a backup while you can, because the problem will get worse over time.

Likashing, the same exact thing started to happen to me a couple days ago. I've hard reset and flashed a new ROM. It seems that the problem is intermittent. After I just let the phone sit for a few minutes, the screen will come back on. It makes me wonder if this is heat-related issue. Anyway, I'm screwed, because I have no warranty since I bought it from a guy in Australia (I'm in US and needed the T8285).
I'll definitely be keeping an eye here to see if there's any resolution other than repair.

while the screen does not turn on, have you maybe tried to use another phone to call your HD and check if the screen turns on when the call arrives?
maybe if the screen turns on it's more a software related issue (so hardreset et cetera might be worth a try), if not, i fear it's hardware

Good point crashDebug... I will definitely try that the next time the behavior is exhibited (right now is one of those times where I can't intentionally duplicate the issue... of course!)

in Taiwan , there are couple of people have these situation, the maintenance staff working Htc, said that it is a motherboard problem or the screen problem...but i wonder that why only few people have this problem. My phone is completely fine before i flash the HSPl1.56OLINEX.but when i try to flash back to Hspl 1.4 , the problem still happen.....

Exactly same problem here
HTC purchased in Sweden.
Cant switch screen on, when incoming calls come it rings but no screen alive. Vibration when pressing the buttons at bottom. And the low battery sound i can here when low on battery.
When connecting it to charger the orange light at power button will not light up (orange) as usually.
My problems started when i had the HTC in my jacket pocket, a VERY rainy day, so the phone was moist OBS not wet. Thats what i beleive ghappened to my phone.
And now i can not find the purchase receipt to the phone

It might be entirely unrelated, but the screen on my THD also had the same problems immediately after a few flights from coast to upcountry 1800m elevation during summer. The system powered up but the display remained off, and no amount of fiddling would switch it on.
The first time it took a few hours and then spontaneously corrected itself. The second time I had to remove the battery for two days, and then all was fine again. Only happened after flights from coast in summer. It hasn't happened again, but then it's winter here in the southern hemisphere.
I suspect condensation, but that's only a guess...

I have the same problem too here in Australia. It started with the screen not turning on but the buttons still work. Then you'll sometimes notice the screen is inverted and upside-down.
I've sent mine in for service. Haven't got it back yet but I understand the motherboard needs to be replaced.
In short, this is definitely a hardware problem and if you look around the discussions on the net, this is slowly becoming quite a common problem with HD.

Yes exactly, I have had the upside down screen too! Well at the very least it is good to know that people are experiencing this problem other than me. I love this phone so I will have to pay to for the repair. If anyone here has any idea or estimate of what this will cost, please share this here.

The problem for me was the moist, after three days it started to react again... And now it seems to be working...
I guess the air up in the mountains are moist... maybe...

So then that's two people so far (including AFW from the first page) who have said that after some situations involving moisture have passed, things are back in working order. I hope for the same to happen soon.

so it is due mainly to wateR?

I doubt it is related to water. My device never gets near water or moisture and still experience this problem. I do wonder if it is heat related as the device can get quite hot during charging and perhaps cause the motherboard to play up after a while.
btw, does any of you use some sort of plastic/silicone cover. I wonder whether this type of cover blocks the heat from dispersing.

As i understand it, so far only people who have flashed a different ROM (and with it maybe radios) to their device. If it's a heat issue it could be something to do with the radio version. I have tried different radios and there was one in particular that heated my phone up like crazy while i was listening to music without the screen on (but i don't recall which one it was).

I only used stock rom and never flash my device and still have problem...

I do not have any type of cover on mine.
I agree with the possibility of it being a heat issue though.

Very perplexing. This past weekend I again travelled from Joburg to the coast (from 1800m elevation to sea level), and again the THD screen stopped responding to input whilst at the coast. I desperately fiddled, reflashed, hard reset at least 10 times to see if I could get the screen to work, but it always booted up locked, and no amount of fiddling would do anything. I even put the thing on an oil heater for a few hours, hoping that if condensation was the culprit (my current theory) then a goodly dose of heat would at least evaporate any moisture, and once, for about a minute the screen responded, and then again went dead to touch. I had to use another phone all weekend. This evening, on returning to Joburg, I resolved to get another device, maybe the Diamond 2. After a few hours back home I retrieved the THD, put in the SIM and, lo and behold, it worked fine. This is most vexing, but I fear the THD will have to go -- I just can't live with this unreliability. Sad, really, because I love the big display, I love the fact that guys like Throy are cooking good ROMs. In many ways the THD is about the best out there, at least for my needs. But that &@&* thing has to be reliable.

HD2 Touch Screen Not Responding

Hi Guys i hope somebody who knows about capacitive touch screens can help me! I have taken my HD2 apart to fix a smashed camera lense. On removing the back cover i used a small screwdriver to prise off the back case and unclip it all round. It came off with no problem, i fixed the camera and put it back together. When i turned the device back on the touch screen isn't responding to my finger on any screen. Like i turned the touch screen off! The hard buttons still wok but nothing from the screen. Nothing looks damaged (I.e the glass isn't smashed). I seem to think i might have damaged something when prising the cover off with the screwdriver. Please, any suggestions would be really helpful!!!

Can anybody out there help with this? I am currently without a phone :-(

I have exactly the same problem, but it happened from nowhere. I didnot unscrew anything. Please Help

Check the flex cable.. this part are very delicate.

same problem
ive got the same problem, mine just stopped working, i performed a soft and hard reset, removed the battery still nothing. it worked for a moment but once locked it stopped working again, only the hard buttons.

same problem but it works on and off. basically the screen will respond until the phone is put into hibernate. the after that id have to push the phone button and end button back and forth until it responds

Same Issue independant of ROM
Same issue here.
Funny thing is it started a week or two ago randomly out of the blue.
Same scenario:
lock the phone can't get touchscreen to respond for unlock
Judging by these posts everyone started seeing this about the same time, maybe it's a software issue or background app .
Help!

I have same problem. It can work for a couple of hours or in 1-2 days then just stop responding, almost every time when in hibernate. Lets just hope it's not hardware failure.

This started happening to me this morning. Out of 50 tries, managed to unlock the phone three times only. This happened out of the blue, right after i removed my phone from the charger.
Have soft reset, hard reset, reflashed ROM, but the issue still remains.
I really really hope this is not a hardware issue.
Does anyone out there know how to solve this? My phone is virtually unusable right now...

Same problem here, I've been testing for about 2,5 months now and today I've sent mine back to HTC . I think it's a hardware problem, tried everything from hard resetting to reflashing. When I press the HTC logo and keep it pressed the screen does respond again. Conclusion: hardware problem.

You're probably right.
I've also tried everything. But kind of strange that if I lock when not on home tab it seems to work. And the screen, almost always, reacts as it should as long as I just dont' lock it.

I just started to get this issue. touch screen works fine until it hibernates. reflashed, still happens. found this in my search:
htcphones.net/htc-hd2-problems-with-touchscreen/

just got off the phone with tmo. they are sending me a new one.

Yeah, it happened to me as well. I opened a new thread like a month ago explaining the problem: http://forum.xda-developers.com/showthread.php?t=710282&styleid=15
and I contributed in another one concerning the same issue here: http://forum.xda-developers.com/showthread.php?t=708530
Summing all up, it ain't caused by a software or a ROM of some kind (at least in my case) because soft and hard resets didn't solve it nor did the flash of a stock ROM. The most probable cause is a digitizer (touchscreen) defect that appears randomly and totally out of the blue. The only thing to do in my opinion is to send the phone in for repair, which I did. It came back with a check mark on "calibrated screen" checkbox. As of now phone's working fine and I hope they solved it even though I read of other people who have had their leo's screens completely replaced..
A curious side note: htc care reset to zero my phone's call duration timers..

I'm not sure if it's the screen. In my case I think it's the connector from the screen to the motherboard, because pressing the housing seems to help.
But let's see if HTC is able to repair it, I hope they are, because the problem is so random they might not even see it

After losing functionality on my touch screen for a week, finally decided to send it in. Took the trouble to revert my HSPL to original and Stock Rom.
Repair should take about a week. Now I'm stuck with an ancient Nokia 6230i for this week. I feel so lost without my ppc. Have had one for as long as I can remember.
Hopefully the phone comes back okay...

I've had so much problem with the screen not responding so I did all backup then reflashed, hard reset to put the device back to stock. Did this during the weekend, I even fired up my old iphone 3g to have as backup phone.
All set today to go to the store and have it repared under warranty.
But since Sunday evening it works perfect. I've been testing it a lot and the screen has not stop responding even once.
This might be just temporarily but does anyone else experienced something like this?

Mine sometimes worked well for hours... days... but eventually the problem came back.

Mine died on me when I was actually out of the country (stuck in Vietnam without a phone). It would work for 5 minutes, then stop for hours. I would have to switch my phone on and off for a couple hundred times before it worked for another 5 minutes...
Got so tired of it that i sent back my HD2 for warranty repair. Expect it to be back tomorrow (or Friday at the latest). Hope there's no further problems with it.

I hate to say it, but the HD2 is known for its highly defective touchscreen. Even when it's working, a lot of people experience strange and bothering events, such as the touchscreen "touching" itself, a very high/very low screen sensitivity all of a sudden, the tilting of the screen to one of the four corners of the device and so on and so forth.
With a device so expensive one would expect it to work flawlessly. Seems to me that HTC doesn't think the way we do...

Digitizer gone - but not completely dead... Any advice? [VIDEO]

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.
Edd

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

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...

Touchscreen does not work

hello, recently my phone's touchscreen does not work. Only when I initially turn it on, it will work until I turn off the screen or if someone calls, I am able to answer then the touchscreen works. Other than that, if I power on the screen, I cannot unlock it at all. I am currently using NAND version of Android on my phone and it have been perfectly fine for weeks. Does anyone have any clue? I have already tried to load a different version of the rom but still the same problem is occurring.

Could be a hardware problem. Send it back for repair.

This is a hardware problem. Send it back to HTC for repair.

Try turning on your screen with the other buttons beside the red end call one.
This happened to me, however, eventually, it stopped working whenever i pressed any of the other buttons to turn on the screen for touch to work also, so it's best to send it for repair while you still can.

For all of you having issues with screen freeze, here is my take. (Before I waste any of your time, I just want to say that I finally had to send it to HTC for repair) This is NOT a software issue but a hardware issue.
I have been flashing roms ever since HTC 8225 came out. I don't want to sound like an expert, but I am an above average user.
I have been using my HD2 for over a year. Then the screen started freezing out of the blue after it locks. Then I had to reboot it and it worked as long as it didn't lock.
Then I figures out that it started working when i awoke the phone by pressing the "BACK" button. So I kept doing that for a while till that stopped working. Then I figures out that if I tilt the phone sideways, almost like changing the screen to landscape, brought it back to upright position, and pressed the back button, it unlocked. However, this also stopped working after few days.
(I also tried to flash many different roms to make sure that this is not a software problem)
Finally the touchscreen stopped working altogether.
Then I called HTC to see if I was still under warranty. I thought I was way past the warranty period but HTC said that I was under the warranty. So I send in the phone for repair and it is on the way back from repair. I didn’t have to pay anything since it was still under warranty.
If your phone is under warranty, send it in for repair as soon as possible. Even if it works for a little while, it needs to be fixed.
I just wrote what I have learned by trying different things. When I flashed factory roms and the screen is totally unresponsive, I concluded that it is a hardware issue.
If you know better, share it with the community!

Thanks for the response everyone.
I have tried to turn on the phone using any other button but the red button and it works. But as most of you already experienced, it will probably get worse. I don't think my phone is under warrantee anymore so is there a repair kit for this?

I have worked on a handful of HTC phones but the HD2 is different. You need to use a soldering iron to remove the touch screen connection. I personally don’t like to deal with stuff like that! As far as a kit, I am not sure. There are videos on youtune which can walk you through changing the screen. Then again, I am not sure what needs to be changed. Is it the screen? Is it the digitizer or something else? Keep searching... Good Luck!

digitizer broken, send the HD2 for repair
Obviously, if you phone still falls into warranty period, reflash original stock WM
good luck
