5. Maintenance

To ensure the longevity and optimal performance of your new display:

• Screen Protection: Consider using a screen protector and a protective case for your device to prevent scratches and impact damage.
• Cleaning: Clean the screen gently with a soft, lint-free cloth. Avoid harsh chemicals, abrasive materials, or excessive moisture.
• Avoid Pressure: Do not apply excessive pressure to the screen, as this can damage the display or touch digitizer.
• Temperature: Avoid exposing your device to extreme temperatures, which can affect display performance and battery life.

6. Troubleshooting

If you encounter issues after installation, consider the following common troubleshooting steps:

• Display Not Turning On: Ensure all flex cables are securely connected to the motherboard. Recheck the battery connection.
• Touch Not Responding: Verify that the digitizer flex cable is properly seated. A factory reset (after backing up data) can sometimes resolve software-related touch issues.
• Display Anomalies (Lines, Spots): This often indicates a damaged flex cable or a faulty display unit. Recheck connections or consider if the unit was damaged during installation.
• Backlight Issues: Check display cable connections. If the issue persists, the display unit may be faulty.
