I've replaced the screen on a 4S, it had an orange fuzz which went to white, which after about 6 seconds went to the normal background as if it was fine.
I replaced the screen again, and at first I got a white screen, then I did a hard reset and the phone's black now. Really not sure what to do.
Just went white as I was writing this, with with a grey border. Never seen this before.
Is something wrong with the motherboard? As this is the second screen ive used
