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.

[Q] Yet another "brick" story...

Note: THIS HAS NOTHING TO DO WITH A ROM UPDATE!!!
Okay... My HD2 has had Android on NAND since last year. No big problems with it, until last week, when it FROZE when I charged it (the screen was still on, but that was it...). I took out the battery and re-inserted it a number of times, and it all seemed OK...
...Until it happened again.
Only this time, it didn't turn on AT ALL. I'm no good at explaining things, so bear with me on this one:
You know how the phone has a very soft and short vibration, followed by a more intense, longer one when turning on the HD2? well, the phone only does the short and soft one, and that's about it... Nothing else...
Does anyone here know what's going on? Is there any way to fix this without returning it? If I do have to return it, is there any way I can retrieve the data on the internal memory? Will they be able to see the flashed ROM?
(Note: It's past its warranty.)

Have you tried to get into boot loader mode? Also who is your provider? Last but not least....You said it was charging and you had the screen on? I don't know about you or anyone else but when I charge my phone I make sure the screens off. It just gets hot while its charging with the screen on. If you have done this more than once it might be damaged from the heat.

mine only vibrates once when I turn it on, not sure what second one you're talking about.
hold the down arrow when you turn it on and see if you can get into the tri-color screen, you can flash WM6.5 or whatever from there.

Past its warranty?
I thought HTC gave 24 months of warranty worldwide?!

i thought that aswell

@jvillejoe:
I have tried to go into bootloader mode, yet nothing happens. My HD2 is from Telstra (I live down under in Australia). Lastly, the charge light doesn't come up if I plug it in while the screen's off, so I have to plug it in while it's on, and then I can lock it as I please. I think it's a NAND-related problem.
@orangekid:
There's an almost unfeelable, really quiet vibration about a second before the usual normal one. To hear it, just put the phone next to your ear (not necessarily the speaker) and turn it on. If that doesn't work, it might be because it only happens on a Telstra phone (I honestly have no idea). And no, it won't let me into the tri-colour screen.
@lukesan:
24 months? I always thought it was 12! Well if I do ship it in, will they be able to detect the flashed rom/illegal Android/everything else? How much jail time do I get if they do?
This isn't the first time it's happened. It's happened about 4 times before, even when it wasn't charging. It usually fixed itself when I took out and re-inserted the battery a couple of times. Are these freezes a result of an app going haywire? Does somebody know the cause!?

well are all the battery pins in place? did they not bend a bit or something?

Yea sounds more like your battery to me

No it couldn't be that... It slightly vibrates a few seconds after I re-insert the battery and then does nothing... but I did notice that the phone would make these small vibrations every once in a while if I leave the battery in, which has convinced me that the battery isn't the problem.

That really sounds like a dead HD2. Them vibrations usually happens when people flash a European HD2 radio on a US.
What happens when you plug it in to your PC? Can you hear a little sound to know that the phone is connected?
Sent from my HTC Vision using XDA App

I had a similar problem (minus the soft vibration). You should try a different charge battery. If that does not help to get in boot-loader screen, I hope your phone is still under warranty.

you wouldn't go to jail? i'm sure flashing your phone voids the warranty but idk if you'd go to prison

[Q] LCD not working, screen and digitizer fine, what could be the problem?

Hello all!
I would like your opinions/knowledge on how likely you think it is that my problem is a simple disconnected cable, and if it would be worth it to take apart my phone (I've never done it before.. but I'm careful) to see if I can just reconnect it.
I woke up one morning and my screen would not turn on =( I did not drop it or get water on it, although it had been very humid. The screen is not cracked and it is still responsive to touch (vibrates when touched on the soft keys on the bottom) but it is completely black, no flickers, no faint images, no nothing. I also have not seen the LED light up since this has happened, when charging or plugged into my computer or anything. My computer DOES recognize the phone, and I have used the Motorola utility to update my phone since this has happened, but that did not fix it. I have tried all of the key combinations and I have successfully rebooted it (I can hear the droid start up noise, the camera sound when I hold power and down volume at the same time, and it sounded like I almost accidentally made a call when messing with it last night).
I have not yet been able to factory restore it or anything like that from recovery, as I am flying blind, but I'm thinking this is a hardware problem with the LCD?
The phone is not rooted and boot loader is not unlocked. It's only a few months old but I bought it used online so there's no returning it or anything like that.
I just don't know enough about any of this to know how to proceed next. Any help would be appreciated! Thank you for your time!

it would still be under warranty by motorola - especially if you accepted the OTA recently (May 2013).
otherwise, I would try leaving it plugged in for awhile (30-60 minutes), then try rebooting it (hold down all 3 buttons)

Thank you for replying!

How do I go about collecting the warranty on a phone that I bought used? And what would happen if it showed water damage? I swear I have not gotten any water/liquids on it, but this did happen after it was very humid out for a while, and I have read that high humidity is enough to spread the red dye (regardless of whether or not high humidity actually caused the problem)

call motorola (or go to their website and bring up a chat session in their online support section)

Try tapping it somehat hard with your finger all around the phone to see if it flashes the screen.

Hi,
For those who have problem with lag:
From Stweaks, change default gov to Lionheart, gpu gov to simple, I/O to fiops, disable android logger, enable zram, reboot.
These settings also give me great batt life

so i made the changes and it did make a big difference. i shut the phone down 2 hours after to charge it,, and thats when a odd thing happened.
its dead.
no life at all. even when its connected to my pc. if i plug the charger in it just gets hot.....thats it.
can i assume its bricked for some odd reason??

what happens if you pull the battery, plug it back in and try and reboot into recovery/download mode?

i did that + charger,and lead.
no responce and all. if i plug in the charger the top half of the phone gets quite hot in the main board area.
im sure some people come on hear with problems with out telling the full storey ( dropping it down the toilet,or just dropping it) but i literally shut it down to charge it quicker.
im still scratching my head over this.
if all else fails i may look into buying one with a smashed screen on ebay and replace the main board as my phone is in great condition,....gutted.

it does sound like a hardware issue - can you take it back to a samsung service center?

iv had it from new, such a shame.

If you tried another working battery, tried connecting to a computer and cant get into Download Mode.... I say your phone is dead and it sounds like a hardware fault. I have seen soft bricked and hard bricked phones, they still show some form of life like the led turning on, pixel salad, black screen (as you can see the screen light up), white screen, cant get into recovery but can get into Download mode and etc.
Sounds like its dead but I am sure its got nothing to do with what you did and its just a coincident that it died.

TMobile S8 works fine, except the screen won't turn on

My brothers TMobile S8 screen randomly stopped working. It has no signs of damage anywhere as well. Weirdly, I managed to get the screen to go on one time by pressing some button combos to try to follow a guide to get it into recovery to factory reset it. Upon the phone booting, the battery had 3% and when I went to show him, it was dead. Now after letting it charge, the screen does not work once again and I can't seem to get it to come on in the same way it did before, the bright blue recovery screen.
Is there any software I can use to just attach the phone to it and factory reset it? I mean, I've seen bad phone screens before that have still had images show up on them, even if heavily damaged physically or it no longer responding to touch and showing dim lights. But this one simply doesn't turn on, except the one random time it did, and it was perfectly fine, showed no sign of damage. Any thoughts would be greatly helpful

Is the battery known to be good?
If not replace it. The system will not boot if there's not enough current. It takes a fair amount of power to boot up. A charger can't provide enough to do so...

It boots up fine, I can hear the initial TMobile boot audio as well as the notification sound the phone makes when it gets to the lock screen. I also had it stop charging @80% not too long after buying the phone on release, with some custom ROM I installed. Ofc its a possibility its battery related, since I can't see anything on it, but it was taken care than the average person I am sure

With a custom rom all bets are off. Makes troubleshooting much harder. Possible rootkit.
Firmware and malware aside if it's booting but no display, possible loose ribbon connector, failed display or mobo. That's assuming the battery is good...

Well I did disable/uninstall Superuser from the phone, and I used it for a couple years before giving it to my brother to use. That is a good point about the cable, I will search for images, maybe I can squeeze a few spots to just see what happens

Sometimes just reseting a connector is all it takes. Those are low voltage lines and a perfect contact is needed.
If the battery is more then 2-3 yo it's probably at the end of its usable service life.

Thanks for the input, I will open it up if nothing else works and I will report back if it helps
