The screen keeps on flickering. Help! Touch is working fine but display has gone all crazy.
Before replacing the screen or LCD try a soft reset, hold the home button then hold down the power, continue holding both buttons until the apple icon comes on. Has the screen already been replaced? If so check to make sure all connectors are clean and put on correctly. I would start with a screen replacement if problem still continues then replace the LCD.
before you put and Sealed the new screen on did you test it and during testing was it working fine. If so you have a bent or pinched flex cable re-open the iPad mini again and test if you have problem still present If so replace with a new screen or LCD.
