I recently set my phone down and then came to pick it up later and the screen won't turn on. At first I thought it might be just cold but it hasn't shown any sign of turning on. I know the phone works because it gives me physical feedback and the led light shows notifications. Does anyone know how to fix this problem?

So i am at home playing with my Xoom fine before going to work. I place it in it's padded bag and get in my car to go to work. No bumps, no bangs, no drops. I get into work and pull it out to play with it some more and the screen is dead, or so it seems. Backlight not coming on. So i think it is dead and force a soft reboot, still can see nothing, i try a few more times, finally i notice if i hold it in just the right light i can see the screen fine, it was rebooting, but the backlight wasn't showing.
I let it finish booting and if i hold the screen in just he right light i can see the live wallpaper moving, so i know the screen is on and working, i can click icons and everything, but the backlight still won't light up. Had to stumble my way to brightness in settings, really hard to do when you can barely make out the screen. Set it to auto, nothing, set it to fully bright, stil nothing.
Is this a hardware issue? Or could i have some random software glitch? I rebooted three times now, hoping it would change. Nope. Stock software, no root, nothing. Had it for almost a month now. This sucks.
I have identified the culprit, but I have not been able to find a solution.
As I said, my screen will not timeout. I have to manually hit the lock button to turn the screen off. Also, the softkeys stay lit. I started going through app settings, etc. No luck. I began to notice after reboots and battery pulls that it only started occuring after I entered mode (*#0011#) to fix the wifi disconnect issue.
After doing that, the screen will no longer timeout. So, at this point, I either have to deal with wifi turning off and on randomly, or a screen that won't go dark on its own.
Can anyone help?
I've had an odd problem with my 820 almost since getting. I'm hoping one of you geniuses have some advice.
When I turn it on it works perfectly, sometimes for hours. Then the screen goes blank, and then random pixels begin to appear, starting at the top of the screen. Outdoors rather than random pixels the screen goes almost totally green. Strangely, if part of the screen is obscured the green only covers rhe exposed area.
Pressing the on button repeatedly usually brings back the lock screen and reset (on+down) fixes the problem for another few hours.
By the way, eventhough I can't see the screen the touch sensor works. For instance I can hold theon button and then swipe downwards to turn off the phone. I can also answer and hang up using earphones.
My daughter who purchased the phone said it worked fine until the amber update. I had hoped the black update would fix the problem but no change. I found some posts from people with the same problem who sent the phone in to be fixed and got it back in the same condition. I really don't want to go through the hassle unless I expect to get it back fixed. I'd rather try fixing it myself.
My question is whether this is a firmware problem an whether it is likely that re-installing the stock black rom would do any more than the ota install that occurred automatically did (or didn't do).
Any ideas?
Nobody?
By the way it seems to happen only, or mostly when in standby.
I installed an app that displays a clock and doesn't allow the phone to go into standby mode,
and the problem doesn't appear to occur (unless I forget to leave the app on top).
I would set the phone to standby = "never" but the option isn't available on my phone, though
I understand that there are those with the standby = "never" option.
Any idea if I can set standby = "never" with keyboard commands, perhaps?
At work yesterday my phone was fine..I pulled it out of my pocket during a break and the screen wouldn't turn on..then I noticed the backlight was on and I can feel the screen vibrate when I hit where the home button should be but no picture. I am able to hear notifications and use my moto360 to make phone calls etc but no picture just a black screen and backlight is on.. Using my nexus 5 currently but wondering if anyone else has experienced this..T-Mobile said they would replace it under warranty.

Hello.
I have the exact same issue, I got a phone with a broken screen, it only had black backlight, then I changed the screen with a new one and still the same thing happens. Tried with two screens.
After replacing the screen I repaired the software via Sony PC companion, but it didn't work.
Does anyone know what the issue is here? Is it a dead motherboard or something else? Just so that I know to stop trying to fix it.
My unit isn't under warranty anymore because it had physical damage so replacing it via Sony is a no go.
The phone boots fine, I get audio reading of menu options for the initial setup, even the touch works, I can select options but I have no image, only the backlight.
Hi all, I've got a weird problem. The last 3 days my screen has been acting strange. Phone is working without problems when suddenly the hardware buttons won't respond any more. After a few seconds the screen goes black and stays black. Buttons are still lit, but don't respond. But the strangest part is that the drawer stays visible and can also be used normally. I mean, I can draw the notification area down and let it fill the complete screen. So the screen itself doesn't appear to be broken.
Also, when putting the phone to sleep and awaking it again, I can see the normal screen a brief moment, maybe half a second before it goes black again. Restarting the phone is the only thing that will help...
I've cleared Dalvik/cache hoping it would make a difference, but it did not. Hope someone has got a clue?
I've uploaded 2 screen shots to show what I mean.
I'm rooted on OxygenOs 1.0.3/Android 5.0.2.
