[Q] Blank screen but phone works? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

So I just got my galaxy s3 friday, and I recently rooted it and I have the Jellybean747 Graystone ROM on it. I don't know if this is a ROM-specific issue, or just a device problem.. I searched the forums and Google and couldn't find anyone else with the problem.
Randomly, my phone screen will go black, and the buttons light up, but the phone works. I can lock my phone and hear sounds from it, like the water sound from the lock screen when you touch it. Even the LED is working. But the buttons won't turn off. Even when it's locked and I wait past my button-timeout time. After some time, it will go unresponsive and not make any noise, but the buttons will still be lit up. The only way for me to shut it off is to take out the battery or hold the power button.
When I restart the phone, it works fine, like nothing ever happened.
This has only happened to me twice, once after I hung up from a call and once after I locked my phone after I sent a text.

I've been having the same issue. I'm not sure if my phone is the problem or the ROM that I am using. I even switched roms and i still get the same problem. I have no idea what causes it but usually I'll be on the phone and when i try to hang up the screen stays black but the hardware keys are still lit up and i can touch the screen and it vibrates. Sometimes it just happens when i unlock my phone and check something and then lock it. I try to unlock it with my home button and power button and the screen stays black with the hardware keys lit up and i can even slide across my lockscreen since it vibrates. When i lock my screen and turn it on again it works normally. I was running paranoidkangdroid and currently i'm running pacman rom the 1/22 version with the stock kernel.

I too just started having this issue. Was running Quantum 3.56. I think it may have started happening after an update, but now after installing an older version I still have this problem. Hopefully someone can find a fix.

TP2 Is On But Screen Black? Help!

I'm wondering if anyone has found a fix for this. I have a Verizon TP2, and yesterday the screen wouldn't come on. I can put the volume up and down (and hear the volume tones), press the hardkeys on the bottom front and those lights come on, slide the phone open and the keyboard backlight comes on. The screen itself won't light up however. If I soft reset with the internal reset button, or take the battery out then put it back in, the screen works fine until the first time I press the standby on the top left of the phone to darken the screen. Once it's dark, it stays dark until I pull the battery again. I can also receive calls, but the incoming call doesn't light up the screen either. I've already tried reflashing my ROM (which I know is a working ROM as it's the same one I've used for months). Ideas? Help!
Sounds like a rom issue or software issue. Go back to stock rom. If problem continues send for a replacement. Also do you have throttlelock or other locker installed, if so uninstall and then test.
Had a similar issue out of the blue yesterday. Phone would go to sleep and not wake up unless it was reset. It was like the power button was not connected. I had to do a hard reset and load up a saved backup. All is good now. Somtimes files get corrupt.
This has been happening to me over the last couple of weeks. It can be okay for two or three days and then happen twice in a day.
I'm on the 6.5 stock ROM, the only thing I've changed recently is the SD card. It's not so bad that I'm going to Hard reset yet (too many settings and high scores to be lost!) but if it does I'll have to. I'm not inclined to flash another ROM given I might have to send off for a repair sometime soon though.
Well my issue is that it's happening even after reflashing a rom, both my original rom and the new Verizon 6.5 upgrade rom. The phone is clearly on, but the screen backlight isn't coming on. I can even press on the screen and hear the dialpad tones as if I'm about to make a call. Is there some sort of reset that might work aside from taking the battery out for awhile? I've tried that, but so far that hasn't worked.
Hmm - sounds like a hardware issue which is more worrying, have you tried HTC support?.
HTC support as in call HTC directly, or do some sort of HTC forums? I've always received my support from XTC
Still having phone issues. I can receive still, but once the screen goes to sleep, that's all she wrote till I pull the battery again.
Well it turned out to be a hardware issue (something loose in the base). I accidentally discovered that if I pressed hard on the headphone or power jack on the bottom of the phone, that the screen would come on. Called Verizon and they overnighted me another free of charge. This one is working great so far...
I got a similar issue, mine screen turn off when fully slide out the keyboard. I was told it could be the "flex".

MyTouch Slide Turns On, But No Display

This has been like this for a couple of months and I have no idea why.
When I turn on my phone it vibrates, then loads into Android but nothing is on the LCD. It makes sounds and lights up, but nothing shows on the screen.
Could this be a hardware or software problem?
Thanks!
is it rooted and what rom are you running if you are rooted.

[Q] Screen flashes after Samsung logo, screen black, vibrates every 2 seconds

My phone just started acting up really weird. Whenever I would graze the power button (not even when I push it in all the way) the screen would lock and sometimes immediately turn back on. Some times the power menu would come up. Other times it would just restart and go into this weird loop where the screen would be black, the phone vibrates, and the LED just flashes. Does anyone know what I should do about this? I was using CM9, but this happened pretty randomly so I don't think its a software issue.

Try flashing a different ROM. There may a bug or something on that ROM that could be doing that.

You just got a malfunction power button. It happens a lot. You need to call samsung/tmobile for warranty service.

[Q] Sleep Issue with BlackJelly Rom V. 08 LIH

Hi guys.
Recently I saw a recommendation to get the Blackjelly ROM V. 08 LIH so I flashed it on my phone and it's been working great. However I am noticing one particular problem with this ROM and need help with fixing the issue.
Occasionally when I lock the phone via the power button, the menu button and back button both light up but the screen doesn't. It's almost like it doesn't want to wake up from sleep except that the phone is functioning in the background. This has happened when I've received a text message while the phone was locked and I couldn't see what my message said because the screen wasn't turning on.
The temporary solution I've found with this has been to hard reset the phone by holding down the home button until the menu and back buttons turn off.
Then turning back on.
I don't want to have to keep doing this if the phone is acting up but I also don't know if this is a ROM-based issue or something else I'm not aware of. Please help? Thanks in advance.

Broken Display?

ok so here is the rundown
Device: HTC one on vzw
Rom: Slimbean 2.x
Gapps: Slim AIO gapps
had a weird problem with the display today if anyone has had this or know someone who has i would greatly appreciate the help. I just flashed Slimbean 2.x last night and all was good. no problems what so ever, got everything setup and was working fine. this morning around 10am i opened snapchat to view a video. i clicked on the video and as soon as it started the screen went blank and would not turn on. i tried holding the power button down for at least a minute and nothing. also tried power and volume down, power and both volume buttons, power and volume up and still nothing seems to work. when i plug it into the wall charger the red LED light does not turn on and screen does not wake. when i plug it into the computer the computer does not ever read the device and noting pops up letting me browse the files on the phone. i have no clue why this happened it has been working fine for the 3 months that i've had it. took it to verizon about an hour ago and they didn't know either but they are sending me a replacement htc one. all i really want now are my photos that i have on the phone.
does anyone have any ideas about what i could do?
thanks
I had something similar and think it was conflict related. After installing the "advanced power menu" with xposed, I had an issue when trying to use it to boot into recovery. Basically it had timed out and then went away without rebooting. The next time I tried it locked up and my screen went black. My keys would light up if I clicked on the power button (it was dark in the room so the sensor was still working), but nothing else. Nothing I did would make the screen turn on at all and holding down the power key to reboot did not work. I just planned on letting the battery die out. After about 45 minutes, the phone just rebooted and everything was back to normal. I really think it locked up due to a conflict similar to what a PC might do.
