Connect to pc to back your data up. Also does the touchscreen work? And did you drop your phone or something else?

the touchscreen doesn't work
debugging mode is not activated, I cannot transfer my data to the pc.
I had the touchscreen bug for some time and suddenly, the screen did not turn on. The phone did not fall.

If it still under warranty i would send it to where you bought it. Even if you dont have warranty try it because the device should not be broken under normal use.

keep pressing the power button and when your phone vibrates try and hit restart. i know your screen is blacked out but if possible just try and locate. it happened with me too and thankfully my devices' screen recovered. the pop up comes just adjacent to the power button. first option will be your power off and then just below will be your restart.

I already tried
the phone reboots well but still black screen

Powering X1i through USB -- any hacks to do the following...

Hi all,
I frequently charge my X1i through USB. There are 2 problems with this method, however.
1) The device goes into USB drive mode, disabling my SD card apps (I keep them on SD card AT ALL TIMES due to frequent backups/restores)
2) Screen does not turn off! while connected to computer! The screen only dims, but does not turn off.
WITHOUT resorting to a) plugging into wall outlet b) connecting to Activesync, is there any to fix these behaviors?
Thanks!
just let it go into activesync mode, that way you can still access your files on your phone and micro sd card from both your pc and phone. And if you dont like the screen not turning off, they just change the settings or just press the power button, to shut off the display.
I know about the power setting, but when your computer is connected to the computer via USB, it refuses to turn off the screen (only dims it)
what? one simple button press and the screen is off. the device is still visible to the pc. I do it all the time - r3a generic uk rom.
in power options u can set after what time it disables screen... default is never

Weird. When I'm connected to Pc, it dims the screen, it does not shut it off. Also, it does NOT auto-shut of screen after the 2 minutes specific in the Power options
You can also use "safely remove devices" to disconnect the data connection from the phone, it'll still charge.
There's nothing we can do AUTO. But like said before, a simple pression on the power button will do it, or you can use My Mobiler and press F11 on your PC.

Yep, I've had 5 different WinMo devices since '05 and they all worked as expected except the X1. I like to use it as an MP3 player at night, Pocket Player has a sleep timer built in so I just like to leave it running as I drift off most nights. But if I do anything, change the volume, rewind, anything at all the screen comes back on and stays on until I hit some other button to turn it back off. All my other devices obeyed the settings you set in the Power tab, but not the X1...
I'd very much like the screen to auto-off if I tell it to while on USB power. It's not only wasting power, but it wakes me up and gets me fumbling for the tiny power button at 2 in the morning. Any fix would be greatly appreciated.
Thanks,
Peter
I bumped up thread: http://forum.xda-developers.com/showthread.php?t=561832 Since it has a better title and shows the exact same unresolved issue...
Reg Fix
Adding this potential fix here as well so anyone subscribed to this thread sees it.
Ok, I think I have a fix for this. I googled around some more and found that this might be an HTC problem more than an SE one. There were various registry keys people suggested to try to fix the 'backlight problem' - which may or may not be related. None of those suggestions seemed to work, but I kept changing keys myself and eventually found this seemed to do the trick.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\Timeouts\ACUserIdle: 120
I confirmed that changing this value affects the amount of time before my X1's screen turns off - but my MP3s still play with the screen off and my phone wakes on receipt of a new call. This value is the # of seconds before the screen turns itself off (in this case 2 minutes). You do need to soft reset for the change to take effect.
This doesn't seem to be posted anywhere else that I've found doing this to fix this issue issue - I changed a few other registry keys as well that might be enabling this fix. So anyone with this problem, please do give this a try and if it doesn't work I'll post the other keys I changed as well - and if it does then post to say so and we're good

Update: I tested it also while hooked up to the computer and it does work with the phone accessible through active sync with the screen off and the battery charging (faster now that it isn't competing with the screen for power, except for the 2 minutes before it times out). If I want to use it I just click a button and the screen stays on till I leave it alone for 2 mins and it remains off. Get a call or a message and the screen goes on for 2 minutes and then off - Exact same behaviour on AC and USB - exactly the behaviour I wanted .

Black Screen

My Fiancee's G1 wont turn on at all,No T-mobile slpash screen or nothing.LED lights turn on and Call,Home,Back and Power buttons light up except for the screen itself her phone wasnt rooted,I have never experienced this before.
Can someone please help?
the phone is not turning on via the power(end) button???
try pressing the camera button and keeping it pressed, also press the power button to enter into hboot mode...if u succeed in entering that mode, the phone is fine, or else it could be bricked.
Try Home+Power see if you can get into recovery mode.
If you can wipe cache data.
Hi everyone, hope it's okay to post this here since this Question relates to mine.
I'm having a trouble like this except instead it's like my backlight went out, it was working fine until my alarm on my phone went off and when I went to turn it off I had to take the battery out of my phone because the screen wasn't pulling up. It flashed basically, so when I put the battery in the screen came on but no backlight. Could it be due to Cyanogen? I'm restoring my backup to see what else could I try?
could u be a bit more specific?phone is working??? calls etc???or are u stuck somewhere????
As I said, the screen came on but no backlight. The phone works fine except for the backlight I'm trying to figure out if it's a hardware issue or a software issue. I don't know how much more specific I can get really except that the only way to see the screen is to hold it at a certain angle so the light hits it just right.

Black screen with backlight

HI every body, I have a problem and I'm asking for help
a while back my HTC HD7 felt in the sea. I managed to get it dried and fixed and it worked fine
but every now and then the screen goes black. normally i fix the problem by taking the battery out
the problem happened again a few days ago, and the screen won't turn on, when I turn the phone on I see the backlights turning on and the touch work fine and I can hear the keys and the unlock screen sound, but can't see anything
I tried to do a hard reset but the volume up key is not working so I can't access the hard reset menu.
my question .. is the a software to do a hard reset via PC. or can I use the headphone volume keys instead of the device ones???
I'm running WP 7.8 official, and a window 7 on PC.
please any help is appreciated ...
thanks

Power button doesnt wake up the phone.

Hi,
My note 8's screen got damaged a month ago, but
from past two days the power button seems to be
unresponsive.
I have to press it atleast 10-15 times for my screen
to wake up.
Even if the screen doesnt turn on by a single click,
the usual touchscreen functions still work.
Ex: I can still open the particular app by clicking the screen
on the specific area.
Kindly help.

There's nothing any of us can do to help you when it's a hardware issue like this. You need to open the back of the phone using a heat gun to loosen the glue and then take the power button out and replace it with a new one.. There's nothing else that can be done and I would suggest that you not shut the phone down or let the battery die out because then you may not be able to turn it back on until you get the power button taken care of!

Hi MrMike2182,
Thanks but let me elaborate the issue.
The power button seems to be working fine because it takes approximately 10 to 15 clicks to turn on the screen (sometimes 1 or 2 click)
Let's say that I click the power button and the screen doesn't turn on, the screen functions work fine despite showing black screen.
Ex:
1. If I click on screen location where samsung music is placed and open it, and if I and click on the location of the play button, it plays the music just fine.
2. If I click on the restart button when the screen is black (not turned on), the phone does restart. The Samsung logo lits up just fine. (Mensing to say, the bootup process is not affected)
Also, note that if I successfully manage to turn on the screen after clicking the power button 10-15 times and if I put it to sleep again. I can easily turn on if I click the power button immediately (within the span of 2 seconds).
The problem persists only if the phone is kept I'd for 5 to 10 minutes.

Ok based on what you said now I don't believe there's anything wrong with your power button and when you press it and the screen doesn't turn on, in reality it actually is on and it's possibly damaged which is why you can still use the screen functions with the black screen. Whatever type of damage you say happened to it could be causing the backlight to not work but the screens touch function is fine.. Try rebooting into recovery mode and select to clear the phone's cache only and see if it helped anything.. If it doesn't help anything it's pretty much a screen hardware problem and you'll still have to get into the phone's internals..

Thanks,
Unfortunately, even factory resetting the phone didn't work out.
Anyway, I will take for service.
Hopefully it might resolve the issue

Since the factory reset didn't work, then unfortunately it really is a hardware issue.. I think you need a new screen..
I have the official led cover case, just opening the case will turn the screen on... Just a temp fix until you can get it repaired maybe.

Phone stuck on boot loop and won't turn on

Phone got frozen while in Messenger, suddenly turned off and now it's stuck on boot loop. Holding volume down and power button does nothing, keeps it on boot loop. When I put it on charging, it heats up, but the charging logo does not show.
Anyone got any clue what might be the problem or how to solve it?
did you receive any pictures via messenger ? that used to be a thing that messed up phones because of one colour outside most phones RGB range.
a bootloop is a cycle, catch it at the right time and you can boot into recovery to clear cache and dalvik.
remember recovery and download mode need the cable plugged into a USB device to nowadays.
the instant the screen goes off hold volume up and power and then plug the cable into the phone (the other end already being in the PC).
if you did receive a file before your problem that'll still be there and the problem might persist. you might need to boot up into safe mode and delete something.
The phone got frozen at the main screen of Messenger, haven't received any messages or pics.
The thing I haven't mentioned but dk if it means anything, sometimes it gets to the Samsung logo, but then it goes off and turns back on.
Tried to hold volume up and power button couple of times, sometimes it would do a strong vibration and then do nothing, but I'll keep on trying.
Thanks for ur help

don't forget the USB cable, you can't manually boot recovery without it.

if you don't mind losing messages next time you could try clearing data on the messages app. you'd need to be pretty quick by the sound of it.
