iPad 3 - No screen/backlight after major surgery
Hey all! New here, kinda desperate for help. My iPad 3 Wifi (32GB) was basically destroyed last year. It's been sitting in a box for about a year and I decided to have a whack at fixing it. The parts are cheap so why not? I had to replace the back case, which required a new battery (as I ruined the original while trying to remove it), a new flex cable for the power/volume buttons (since I tore part of it while trying to remove it), new screen and new digitizer. Prior to starting work, the backlight did come on and I could see part of the screen showing the time and the wallpaper, so it was booting into the lock screen, but the home button and digitizer were completely gone so I couldn't shut it off (tried the power button+volume button down solution but it never shut off), just prompted the swipe to shut off. Anyways, I've got it mostly reassembed, but upon testing prior to sealing it up, I'm getting no backlight or as far as I can tell anything on screen (by shining a light directly on it). Tested with both the old panel and the new and nothing. Plugging into my PC and my mac, iTunes seemingly recognizes it's an iPad (with name 'iPad') but because it's passcode locked, it won't go any further (which is fine). So it's obviously turning on, but I'm not getting anything at the screen.
