Hi, I just replaced the digitizer on a friend’s ipad, and being my first time I disconnected the screen with a metal screwdriver (big mistake). The iPad boots and I can see the Apple logo perfectly, but then, when it gets to the lockscreen it turns pretty dark, I can only see something with a flashlight. Any idea as of what to do now?
The best thing to try first is a hard restore which if the digi is still off touch both probes with something metal inside under the lcd by where the home button is. If there was any damage to the digitizer flaps (FPC’s) than that is a bigger problem and will require a soldering repair. Was the device powered off when you took the lcd and digi off? Update this to let me know what happened Please!
Your backlight filter isn’t fully blown but has too high of a resistance. That’s why you can see the apple logo at first but dies during the iOS screen. You can test with a meter (resistance value of .2-.3 ohms). If its out of spec, you could jumper it but its easier and overall safer to replace. I have replaced lots of these. You can email me if you need service.
just disconnect the battery and leave it for about 10 seconds and connect again….i did it to mine when replaced the touch screen and worked…!!!
