Troubleshooting Guide for iPad Screen Replacement

Here are common issues encountered and how to resolve.

Important: All screen parts have a protective film on them. Keep this on until the repair is complete and then remove.

Recommended Troubleshooting Steps

1. Clean the digitizer flex cable with ethyl alcohol (C2H5OH) and carefully attempt to reattach the cables; make sure all cables and connections are secure.
2. Make sure your device is charged.
3. Do a soft reset of your device.

LCD display not working / won't turn on

  • If you have an all white or all black display, start by performing a soft reset on your device. Blank and white screens are usually a sign of the internal software not wanting accept the new parts. A soft reset will clear your device of any temporary data that is blocking your new part from working.

  • Check to see if your screen’s back light is on. If there is no back light in addition to no display, your new LCD is not plugged in correctly. Reattempt the repair, and make certain your new part is fully installed.

  • If you see yellowish blotches on your display, this is a sign that too much pressure has been applied to the LCD at some time. Open your device again, and make certain there is no residual glass from your original broken screen. After clearing your screen, disable your phones “Sleep mode”, and leave your device on a charger for 24 hours. The heat from a constant charge can cause the crystals inside your device to move back into place.

  • If your screen has lines down your display, then you have a defective or broken screen.
  • Touch not working

  • If your iPad touch digitizer will not respond to touch at all, make certain the flex cable is not crimped (folded too much) or damaged. The flex cable is very fragile so do not bend or handle roughly. Crimping causes micro fractures in the thin metal inside a flex cable. Once this metal is cracked, power and other impulses cannot flow through the device.

  • Also check that all your cables are fully seated and plugged in. Flex cables that need to slide into position can easily come loose during reassembly.

  • If only part of your touch screen is not working such as the top third, or left side, you may have a cable that is miss aligned. Open your device, and make certain all the connectors on the flex cable match up. If this plug is off center, you will see problems such as this called “blocking”.

  • Blocking (where part of screen touch doesn't work) can also happen if either your digitizer flex cable, or your motherboard FPC connector plug have missing or bent pins. These pins will need to be put back in place before your device will work again.

  • If you discover pins are missing on the digitizer connector plug on the motherboard, we recommend having a local repair shop or an online repair service fix it for you as it requires micro-soldering. There are many repair services that can do this for you by mail.
