So im repairing a iPhone 3GS and the front Glass is pretty Mangled. And i took the Digitizer off and put a new one on. Suprisingly easy! And after all screwed in the top wasnt clipped on so i pushed the top left back down. It made a nice click as it snapped in place. Only thing is, the screen went bright white and lost all picture. i put this down to software straight away, as the sleep button performed correct turning the LCD on and off. Then after a power cycle the LCD is now gray. again no image just the backlight. I can just replace the LCD but im pretty sure this wont fix mutch. Its not damaged in anyway, And i have seen my fair share of broken iPhone LCD's. But i have never had this problem. Also the digitizer doesnt seem to be working Is this linked with the LCD? So yeah.. Iv tried a Hard reset and power cycles. Nothing seems to work. Oh and the iPhone isnt mine! Any one else had this problem?
