Nokia :: N79 Locking Phone Or Letting Back Light Shut Off - Device Won't Turn On

May 29, 2010

I purchased my N97 about a year ago and I absolutely adore it. I haven't run into any problems until last week. When I turn on my phone, enter the unlock code and use it to do whatever I need to do, it works fine. However, if I lock the phone or let the backlight shut off, it won't turn back on and neither do the lights on the number keys. Here is the funny part: If I press the power key (as if I were to change my profile) the backlight turns on, allowing me to see the screen, but the number keys don't light up! Does anyone know what I can do?

I'm not very tech savvy (so please don't laugh if my solutions are completely wrong), but here are some of the things I have done to try and rectify the problem:
- Let the battery drain completely and charged it in the hopes that it would rectify itself like it has in the past with other issues
- Took out the battery, SIM card and memory card just to make sure everything was inserted properly
- Restored the phone to factory settings

Galaxy S5 :: Phone Shut Off And Won't Turn Back On?

Jun 11, 2015

My phone shut off earlier, while I was using it. The battery was just about fully charged, and it was plugged in. I've tried holding down the power button, power and volume down, power, volume down, and home. I tried taking the battery out as well. Its been a few hours, and it still wont turn on.

LG G4 :: Phone Froze And Shut Down While Watching YouTube - Won't Turn Back On?

Dec 21, 2015

So I have had my AT&T G4 since last June and it's worked perfectly fine. Suddenly tonight as I was just watching YouTube my phone froze and shut down. I tried taking out the battery and it won't turn back on at all. The LG screen shows up and then it loops a bit before going dark and the power button won't work. Not until I replace the battery again. And the cycle begins anew. Sometimes the white AT&T screen shows, but still nothing. Once I got it to a screen that was optimizing apps I think. But that quickly failed.

I haven't factory reset yet because I do not want to loose my information and I don't know if I even have a back up. I don't know what to do and I can't be without my phone.

Nokia Nseries :: 5630 Won't Turn On And A Blue Light On Back

Nov 14, 2011

My Nokia 5630 got wet. After that I dissembled it and dried it. Everything was ok beforer the second reboot. Thats when I reseted my phone. It obviously failed. Now when I plug my phone in to charge (either to usb or just power) the blue light on the back (on top of the 3,2 MPix camera) is always on until the battery runs out. I have tried the *,3,answer button (green) trick and that also didn't work. My phone just won't turn on.Also, I have tried removing the sim card (as shown in the attachment) and memory card and that didn't work either.

Nokia :: N95 Screen Is Very Dull On Main Menu - How To Turn Back Light On

Jul 28, 2010

I have a N95 that has a weird screen issue. I've spent just over a week looking for an answer, searching Google and forums.The screen is very dull on the main menu, to the extent that to see any data on it you need to be in a very dark room. The screen saver however is just as bright as it has always been, brighter in fact.

I've turned the screen brightness up to full but this made no difference. It is almost as if the back light has been turned off.Does anyone know how to turn the back light on or even any resolution of this so I can use the phone during the day.

Google Nexus 5 :: Suddenly Shut Off And Won't Turn Back On?

Jun 1, 2015

Was on my Facebook app checking a Notification when suddenly the buttons to return to home screen, back and move between currently running apps stopped working. It is not unusual sometimes the touch screens don't respond and the easiest fix would be to press the power button to go to the lock screen and come back. When I tried turning on the phone to unlock it, it never turned back on.

Motorola Droid Bionic :: Screen Will Shut Off Then Immediately Turn Back On

Nov 18, 2011

When I hit the power button on the phone to make it sleep, there seems to be a very small chance that the screen will shut off, then immediately(within a second) turn back on.It could be placebo but I think having music playing makes it happen more often.

IPhone 4s :: Won't Turn On And Back Light Always On

Aug 27, 2014

Recently I got a broken Iphone 4S from a friend and he told me he dropped it, so it doesn't show anything at all. I thought it was a LCD problem so i bought a new lcd screen from amazon and well it some-what works. I hear siri and it vibrates a couple of times (vibrates when i plug it to a charger) but the screen is off , nothing no light or anything, also the light in the back is always on (it did that before). My question is whats the issue now? and is it still fixable? Also i can't connect it to itunes because of password and i don't know how to unlock the phone through the computer.In addition, I already tried holding the home and power button for 10-20 seconds, even holding just the power button...

Its an A1387 model Verizon with 16GB running IOS 7 ...

BB Bold 9700 :: Device Set Back Light Goes Off After 20 Seconds

Jul 6, 2010

I've had my AT&T Blackberry Bold 9700 since November of 2009 and am just experiencing this problem. My device is set so the back light goes off after 20 seconds. Whenever I put it down or lock it, the back light goes off just as it should. But, within 5-10 minutes, it turns back on without provocation and won't shut off again until I unlock and re-lock the phone.

As you can imagine, this is killing my battery life. I've tried playing with the settings, but nothing seems to do the trick. I've rebooted several times and removed the battery twice, but neither has worked. Anyone encounter this issue and/or have any suggestions on how to fix it?

Galaxy S5 :: Blue LED Light Device Won't Turn Off?

Mar 26, 2015

There's a blue LED light on my S5 that's been on constantly since yesterday. I had LiteFlow installed, but I uninstalled it because I've heard there are issues.

I pulled the battery and I've restarted the phone. Nothing seems to make it go away. The light comes on as soon as i put the battery back in, before the phone is even turned on.
