[Q] Galaxy s4 screen not turning on

Hi people. i need help! all of a sudden led screen of my gt-i9500 whet dark. the phone is turning on and working. i can unlock my phone by drawing my pattern code and i the phone vibrates when i draw the pattern and i know touching is working. soft keys also are also working. but the screen is completely black. i thought that it can be software issue so i tried to boot into recovery and download mod. recovery mod shows nothing. but when i boot into download mod, sometimes there is a sudden green flash and sometimes the text and the android logo appear for like a second or less, in a very low brightness and then turns completely black again. so i guess it is not burnt. is there something i can do? please help me!!

[Q] Black screen on samsung galaxy tab 4 problem

I appreciate any responses anyone has to help
Ok so i have my sisters samsung galaxy tab4 ( sm-t230nu ) which she brought to me today.
Her screen went black, lights up and all but it stays black in color. Up down volume buttons work and u can hear them working, power button works, turns screen on and off, TOUCH SCREEN WORKS, on certain areas u can hear the noise it makes when u tap on the screen and apps. I pressed the power button alone for it to restart, it restarts but does not show samsung tab logo or anything at all just lit up black screen. I even went on YouTube to memorize the hard reset sequence of buttons u have to press in order to complete the reset and i did manage to hard reset. But screen is still booting up on a lit black screen. I removed the back cover, unplugged the battery and tried booting it up and still nothing. BTW its full factory, no root roms or anything of the sort. I need help on what could be the problem. Only thing i believe might have caused this was a recent update on the system. My sister said a few days ago it gave her a notification about it and she clicked on yes. I dont know what version of android it had nor which it had updated to. Please help. Tablet is not that old. Thanks. If anything email me directly at [email protected] thanks

Have you tried getting into recovery or download mode? If those show, it's likely fixable. If you can get to recovery mode, it usually shows what firmware is on it. If that works, trying using ODIN to reinstall that firmware in download mode. If not, it sounds like a hardware problem. If it's not that old, it may be under manufacturer warranty still. Good luck.

Try to reseat the LCD cable, if it doesn't work, you may need to change the LCD. Search Ebay for LCD only or full LCD assembly if you're not comfortable to take out the touchscreen.

If tab has warranty claim warranty. I think this is a hardware issue.

Blank screen, notification and menu lights on.

Hello all, I just traded my nexus 6 with a note 4 and it worked well for about 3-4days and now i'm stuck. I received a call, went to answer and the screen was blank. Tried switching off the phone to no avail. Pulled the battery and tried to power it back up again all I get now are different shades of blue led notification then the menu and back buttons light up and that's it, screen blank.
I did try the many ways shown in google to remedy this but nothing works, pulled battery, held power button for 1-2mins and then leave the phone alone for a while and then come back to power it up. Nothing works. Did the guy set me up or did it just happen on my watch. I'm pretty sure he would say that he gave me a fully functioning phone, which he indeed did. Should I just get a new board or am I screwed?

Nothing......cool.

I think I flashed a wrong ROM to my S4 and now it won't turn on

It won't turn on it will just vibrate briefly and show the Samsung splashscreen then black screen and nothing else. It won't show the charging screen either just vibrates briefly every 3 seconds or so. Also can't boot into recovery mode does the same thing as when trying to turn on. Help please?

Try going to download mode and if it worked go back to stock ROM and try a ROM that is actually compatible with your device

Zenfone max pro m1 Blank Screen

Hello Everyone..
What happened: my phone was suddenly stuck/freezed. I switched it off for a reboot but it never came up again. Now I am stuck with a black screen. The phone was not dropped, not exposed to water.Already triedower button short & power button for 10sec / 20sec ...Volume down & power buttonLeave it for dischargeCharging it over a long time (with original 1+ charger)Connect it to PC (does not recognize the phone)Nothing worked and I cannot access recovery mode.What it still does: it just vibrates occasionally when I press power or volume down & power. However, it stays black, no boot logo/splash screen. Very infrequently (maybe every 10th on/off) there is a short blink of a red warning sign, which i was able to record. It says the "battery is too low, charge for a while before..." even when charged for a long time!

You may have set e light wallpaper backgroud wallpaper that turned the pattern dot into blacks. So basically the dots are there . Draw your pattern by guessing the dots. The device wil be unlocked. Then change the wallpaper.
