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!)

...i have no warranty too....
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.....

i have tried diff rom and diff HSPL....
sometimes, the phone's screen still can turn on luckily, then i can go to bootloader mode, but if the phone sit for a while, the phone's screen can't turn on...then i can't get into bootloader. ..
i can hear sound when someone phone me...but the screen still keep dark!

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.

lockbot break touchscreen?

Hello all, im still having issues with my touchscreen being i guess mapped incorrectly or sometimes hardly working at all. The more i think about it the more i have to think it can be fixed and also i think about anything that could have happened to the phone b4 it started acting up and there was nothing, not a drop or hit. The only thing i can put on the same timeline is right after i installed lockbot is when it started acting up, is this by chance only or is there a chance lockbot modifies a file that could affect the touchscreen? Any help with this or even ideas would be great. Thanks, veritas
Ps...also after searching google for a few days i noticed a good bit of people posting that they had diff issues after installing a couple diff lockscreen apps, the only issue is that they are all only open post with zero responses to point in the right direction. Thanks

This happened to me too after installing lockbot.
I'm gonna try to reinstall the firmware and will get back with the result.
Currently it just comes and goes .. mostrly comes.. The bottom part of the screen doesn't work at all, and the sliding seems to work harder. Also, when I type a message in landscape, I press a key, and another one is actually shown to be pressed.
I also tryed different versions of lockbot, 1.8 and 1.13 before the touchscreen sarted to have problems, but when it actually happened, I had version 1.8 installed and it froze when I was using it.

Just reinstalled originial firmware, and problem didn't go away.. this is starting to get serious..

i seriously doubt it's related to lockbot. many people use it with no issue.

yeah.. lockbot might have been a coincidence.. I realized that I was using a different charger (not the original one) when using the phone when this problem appeared, and this seems to be consistent with the problem.
Actually I was charging the phone from the usb port of the computer, using also an USB extender.
I'll take the phone to waranty .. I tryed removing the battery and not using it for a day, leaving it to use up all the battery.. no success.
I think that there may be some wild static running through the phone from when I charged it off the usb.
If I play with the phone a lot now, sometimes the bottom part works bot not the top part.. and sometimes, I can press something on the screen just by hovering the thumb over it.

I'm getting the same problem! I press at the bottom of the screen and it selects something in the middle or nothing at all and at the home screen I won't even touch the scrren just hover my thumb over and the screen responds like its trying to go to the next screen but then gets stuck in the middle.
I called t mobile and they said to soft reset or hard reset, did both and no fix.

It's definetly a hardware issue.. it's sad that these touchscreens are so sensitive to the charging currents..
I would have imagined that they would have added some protection for this ..
btw, it's not just a htc hero problem, the web is full with all types of touchscreen phones being afected when using non original charger.

That's ALL T-Mobile knows how to do. Reboot your phone or reset your phone. If that doesn't work, they tell you its broke. Anyone could do that job.

ANY phone gets affected when using a different charger. People don't stop and look at the voltage of the new charger and leave their phone on it for 10 hours even though it's charged.
You can't protect from stupidity. Not saying any of YOU are stupid, but seriously, don't give your phone 100 volts when its made to receive 12.

I quess that ppl that use non-original chargers would read the voltage output..
Like I said above.. I just used the usb port from the computer to charge, if this is wrong, maibe they should have disabled it

I was saying here that other parts of the phone are just fine.. if there is a problem with the charger, why doesn't the whole thing brake.

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.

ditto.
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!
Code:

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...

[Q] Ghost key pressed, worse with MDJ recent update.

search for "ghost" "key presses", nothing relevant so here we go, hope to get a response on this one or I am going back to another ROM
I am getting really bad ghost key presses with this ROM, I used them with WINMO roms but a fix was released. This suggests the screen driver for Android is not yet stable and needs more DEV or is it just me that is having this problem. Sometimes it is so bad I feel like dropping back to winmo, yes I know it is that bad.
issue 1:
Sometimes all the keys around that key I am pressing fire and not just once, several times, mostly on edges of screen.
Issue two:
Sometimes when I have finished a word I get lots of ghost presses and random characters as if I am running my fingers all over the keyboard.
Could my screen be faulty?

I saw that, however the problem pretty much goes away on winmo ROMS, dont want to go to the bother of removing spl/mag and android to send it for repair if it isnt broken, are you 100% positive my screen is damaged?

Yes dude ...100% sure ...when i had this problem it was negligable on the windows mobile and more on the android builds...its sooo anoying ....just get ur screen replaced ...u will start loving android buils

Thanks, I will look into this, phone is still within warranty.

He's right, see my thread here. I had exactly the same problem as you. Sent my phone back to HTC, replacement screen, no more bounce/ghost keys.

didnt see that, didnt think of searching for "bounce"
I have put in a support email to HTC.

@Major_Sarcasm --- i still remember how much i had to convince u to change ur touchscreen !

[Q] Touch screen intermittently wont work from lock screen.

I have the WP7 installed. No dual boot.
I have a password protected lock screen, and every once in awhile, the touch screen wont work, so I can't slide up and put in the password. If I hit the windows button in the middle, it kinda bounces for a second, then goes dark again.
It happened yesterday too, and the only way I fixed it was to turn it off, take out the battery and then turn it back on again.
When the touch screen works, it works fine. It's perplexing.
Anyone else have this problem?

Yes, but I only have to tap on the screen and the touch screen is working again and I can slide up the screen. Had this happen with both of the builds I've used so far.

This didn't work for me. My phone's been locked all night.

Hmm, not really sure what it could be. Check with whoever built the rom you are using, they may have a better solution. Sorry I couldn't help more.

Its a hardware problem, not software, i had the same problem the solution is to change touch screen, try to press touch near red button for same time it can help, but not for long time.
Sorry for me english)

Common problem. Your touch screen is fried (or is in the processing of frying). Start the warranty process now.

fried? dunno mate, when my touch screen goes on the blink i sweep a finger in the opersite direction to what i usually do then try again straight after, so forinstance, at the lock screen i try up and it doesnt work, so i try down then up and that usually fixes it, same for the tile screen, if it wont work as i sweepleft, i sweep right then left.
this doesnt happn on android which i would think rules out an overall hardware fault, at least for me anyway, it is however hardware related, the HD2 shouldnt have WP7, the drivers are not designed for our device so expect these odd happenings.
Of course its equally likely that this could be another sign of the pain in the arse SD card issues some of us suffer, reflash and try a new SD card and see what happens.

Man its realy problem of touch screen because it breaks in zone of red button, and when you press it some times it goes ok, and works wery well, but it die from now, replace the touch or it will die in few - weeks- days.

i would seriously get that accusation backed up by some proof before someone does something they didnt need to do.
I have random unresponsive screen issues that are directly related to the install of WP7 it does not happen on android or WM, there for its not hardware, at least in my case, its driver
