Backlight issue => bad connector screen solderings?
I get an iphone 5 which go into some water (red sticker)
All is working except the backlight which works but at a low level so to determine if it was a problem from the motherboard or the backlight itself, I put another working screen on it and.... the same thing however when I test it the screen wasn't in its compartiment so I can slightly moved the screen (and the connector is a little affect to this action too) and the backlight is directly affect; more bright or less depend on the orientation of the screen.
So I looked closely on the screen connector and it seems that the screen connector is badly solder on 4 pins (judge by yourself thanks to my pictures), can you tell me or confirm that these pins are used by the backlight ? or just send me the scematics of this chip
Is this a good question?
