Screen - Galaxy S III Q&A, Help & Troubleshooting

So my girlfriend dropped her s3 the other night , the screen stays off ( does not light up ) but the touch sensors still work, we can answer calls on it by knowing the approximate location of the answer button, any thoughts on what the issue is ? I would prefer to repair this at home rather than make her pay money through a shop, thanks in advance

It is easy to replace broken GLASS.
but i think you will need to replace screen.
If you purchase assembly of glass, digitizer and screen it will be very easy to replace by yourself.

The glass isnt broken, perfectly clean with no scratches cracks or nicks , it just wont light up;

i had the same problem once, had to be sent to samsung (or wherever) by the shop where i bought it
buying a display and metal frame (obviously you can't buy them seperatly) plus glass would have cost almost the same
i wanted to find out whether the screen still works and it's a problem with my motherboard or vice versa so i unscrewed all bolts to access where the screen is plugged in on the motherboard but i didn't have another s3 to do the same and check it :silly:
still don't know how amoled displays work so it might be possible that whatever's responsible for backlighting the display broke

My thought was that the backlight broke or maybe the entire display system is disconnected , I might just have to take it apart for an exploratory operation,

before it went completely black there was a purple stain which grew until two thirds of my display were purple, the lower part where it started was black.
then i managed to open this samsung hardware debugging menu where you can check for dead pixels by letting your display light up in red, green and blue. there i found out that only blue and green pixels very working correctly in the upper third. the next day every purple pixel was dead.
so 2 months after this little stain appeared my whole display was in the same state as your girlfriend's seem to be now.
so i don't think this plug (it sits in place pretty tight) got loose and that's why it doesn't work anymore.
and my sister had exactly your problem. she dropped her s2 and it immediately went black
she hat to sent it in as well ...
good luck
if you find out what's the problem and want to share it, i am curious about it as well

If possible, check for loose connectors first.
I don't know about replacing the screen. The sheer amount of LOCA makes it a messy job.
Probably the display is dead. You'd need to replace the screen+glass.

There is no back light on an oled screen.
