I replaced the digitizer screen as well as the wifi antenna and when I plugged it in… nothing. Won’t come on at all. When I was in the process of replacing parts I plugged it in (not while I was doing the work) so that when I was done it would be charged enough to check things out and see if everything worked. When I first plugged in the power I noticed that it was kind of flashing, faint, more like a flash from a TV trying to come in. So I unplugged it and figured that I could just charge it when I was almost done. That didn’t work. I don’t even get the flash any more. This all began because of a broken digitizer screen which I unfortunately have replaced twice over time Any thoughts?.
try to hook it up to power and see if its just your backlight. shine a light where the apple logo should be and check if you can faintly see it, also have you tried connecting it to iTunes?
