Troubleshooting

Black Screen After Installation

If the screen remains black after installation:

  • Ensure the battery is properly connected and charged.

Unresponsive Touch Screen

If the touch screen is unresponsive or has dead zones:

  • Re-check the flexible cable connection for the touch digitizer.
  • Ensure no debris or foreign objects are between the screen and the phone frame.
  • If the issue persists after re-seating connections, the screen may be defective. Contact customer support.

Display Issues (Lines, Discoloration, Pixels)

If you observe lines, discoloration, or dead pixels:

  • This often indicates a damaged flexible cable or a defective screen.
