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?

Click to expand...
Click to collapse
I don't think that's the cause. There have been reports of the sleep of death after all sorts of time frames. I've never encountered it, so I can say for sure, but check the bug tracker on CM9.
Well that exact same thing happened to me and it worked fine after I did that.
Power
Try plugging it to a power source and plugging it out
that may jog its sleep
Hold down the power button until it is completly shut off. Then turn it back on like normal. I have had a screen of death after using CM9 for 1 minute and as long as 3 hours later before. It's not nearly as stable as the CM7 ROM.
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???
Hi guys. So this is my situation; my phone is currently turned off.
If I hold the power button, the Samsung Galaxy S4 logo appears in with the black background, then disappears and the phone turns off after 1~2 seconds.
If I hold the power, volume down button then I get the custom OS screen. If I then choose to restart from this screen, the phone restarts and the Galaxy Logo shows for around 6-8 seconds then disappears again.
If I go to the custom OS screen again, then press restart, I can then hold the volume up button and the lock button and the blue message saying 'Recovery Booting..' along with the same black Galaxy logo then the screen disappears after 1-2 seconds seemingly turning off, then it vibrates once after a couple more seconds then does nothing again
I can not get the recovery booting screen from simply holding Volume up and the power button, I need to do it after restarting through the custom OS screen.
My phone is also suddenly not recognising the charger being plugged in. There is no observed difference between attempts to turn it on with/without the charger plugged in.
The last time the phone was properly turned on, it switched itself off at around 4-6% battery left and from then on I have this result.
So, can you guys help?
Your power button is probably faulty. Try to wiggle it lose or replace it.
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.
Please help I was using my phone when the screen suddenly goes off but the phone is on, the screen is blinking (lights up and off) continuously but it stays blank. I can open and close the screen by clicking the power button as you would normally do if you're checking the time on your phone. I tried pressing the power button for more than 15 seconds; tried the volume down + power button for more than 15 seconds, and tried the volume up + power button combinations. I tried it while it was connected to the charger and I also tried it without connecting to the charger. All it does is restart/boot my phone I know because it vibrates, but no logo, no display of the battery charging, but the notification light turns red when connected meaning it is charging. I can connect it to the computer also and it displays my device's model. But all in all the screen just stays blank and just keeps blinking (like lighting up and down). The phone wasn't dropped and it did not get wet by any liquid substance, when it happened the battery is up to 87% and I left the screen off for 4 hours before using it then it happened. I am out of solutions as I can't also reset it as there is no display even the logo and battery charging display are gone. But I know it is alive because I can turn it on and off and connect to the charger and pc. If anyone knows or can diagnose the root of the problem it can lessen my worries and maybe just resort to bringing this to a cellphone repair shop. Thank you. TT____TT
