OK - so I have searched and can't find a solution - so hoping someone can help! My Nexus 7 is effectively dead at the moment
So, I noticed what appeared to be a bug with the automatic brightness a couple of days ago, where if I tried to turn on the screen in a dark room it wouldn't, turned the lights on, worked fine, I then set it manual brightness so I could the lights off - so figured fine, probably a software bug, will be fixed in 4.1.2 or whatever.
Then yesterday I was playing with the auto brightness again, set it to automatic and instantly the screen went off and I haven't been able to get it back on. I have tried:
1. Reboot (holding down power button for 10 seconds). Result is Google logo comes up, followed by nexus logo (so backlight does work) then the screen goes off.
2. Factory reset (hold down power button and both volume buttons) - picture of Android lying on back comes up. Interestingly when plugged into power the buttons are then unresponsive, but when I do this under battery power they work. So (under battery power) I selected Recovery Mode, and the screen then shows the Google logo for in excess of an hour. It doesn't go any further. So I can't factory reset either!!
When the screen is off, I have plugged into my computer, and it recognised. I managed to unlock it once (by guessing the pattern unlock) and I could see the file system. So it is on and working, the backlight is just off and I can't find any way to turn it on!
It is not rooted.
Any ideas or help???

This phone just broke after 3 months of use. Since I brought it off of amazon as unlocked, I do not have warranty on phone. The phone was not dropped nor water-damaged. It was sitting on the table and suddenly experiencing problems with lag. I proceed to turn off and try to restart phone.
The phone does not boot when I press the power button.
What I've tried:
case 1: I removed SD card, removed battery and removed USB cord. Press power button for 10 seconds. Put back battery and press power button
result 1: LED light on. The phone vibrates 5 times. Remains in black screen
case 2: I called my phone number from another phone
result 2: Straight to voice mail. This indicates the software did not even boot up. Hardware display is not the issue here. Most likely a Software issue.
case 3: I hold volume down key and power key to attempt hard-reset
result 3: LED light on. The phone vibrates 5 times. Remains in black screen
Since I routinely backed up my phone data. Last time I've checked (~4 days ago), the SD card was not nearly full. It was approximately 25% used space.
PLEASE HELP!! YOUR HELP WILL BE APPRECIATED!
Are you able to access any of the service menu's such as bootloader or fastboot mode?
If your not aware what those are, there are many references in this forum for you to find information.

No. The screen was all black. But fortunately, the phone was able to turn on after some trial and error.
You remove the battery and USB cord. Then while pressing (and holding) the home button key, you put back in the battery and press the power button. To hard reset, you must press volume down key, home key, and power key at the same time.
Glad that you got your phone working!
Mine continues to remain dead
I had this problem a few months back at first i too thought the phone was dead - but it did make boot vibration noise - but the screen would always remain "black" but after some time and after going into a very dark room i was able to see that the screen was not black, but that the backlight went out on it -- after having my screen replaced the phone now works fine - think i was using cm7 at the time.. hope this might help
Thanks for this tip! I'll check on the phone I had as well. I got to get it back from my buddy.
If I press the power button on my G2, the screen comes on, and goes off after about 1 second. During this one second, I can unlock the screen and do anything but the screen ultimately goes off. the only way to use my phone is to turn the screen on by plugging in the charger, or by pressing power button volume down at the same time. this switches the screen on normally. Tap to sleep works perfectly but tap to wake isn't working. I've tried factory reset. I've cleaned cache partition. I'm all stock no root. Any help would be greatly appreciated! Thanks!
I was just surfing through the net, I left my phone on bed & went to the bathroom, came back and found that the display won't turn on. Pressing the power button caused the back,recent apps buttons to light up but that's it. Even the LED notification lights work whenever a notification came.
Note : I think the phone turns on properly when I hold down the power button bcz I hear sounds, the led blinks, the phone even vibrates. But the display stays pitch black all the time.
What I tried :
Take out the battery, leave it for a few minutes then put it back on and try to turn on the phone.
Take out the battery and hold down the power button for a minute then put the battery back in and try to turn on. This time the phone turned on but when I pressed the power button once normally to turn off the display, it won't turn back on.
Try to go to recovery mode (Power+Home+V. UP). This worked once too but when I cleared cache and rebooted the device, it didn't turn back on.
Try to go to download mode (Power+Home+V. Down)
Plug the phone to my PC through USB cable, PC detected it but nothing happened.
Sometimes the phone turns back on normally but after a while it dies again. I checked the battery, it's fine.
My S6 lite (never flashed a ROM, running original OS) has a terrible problem: after being turned on, the display blacks out -- but the backlight is still on! The only way to get it to respond is to push and hold power button and "volume down" at the same time. This shuts it off, then I can turn it back on again. A few minutes later, the screen blacks out (but the backlight is still on) and the cycle repeats.
Ideas?

Just recently, my remote power button and menu sleep option stopped working. The green light on the device goes off for a second but then turns right back on! This device had been fine for two years.
Tried rebooting, no help.
