2. Installation Preparation and Precautions
Professional installation is highly recommended for this product. Mobile phone LCD screens are fragile and require specialized tools and expertise for proper installation.
2.1 Before Installation Notes
- Test Before Installation: Before proceeding with full installation, it is crucial to test the replacement screen. Do not remove any protective films or tags during this testing phase.
Pay close attention to the issue of static electricity. Before attempting any repair, ensure you ground yourself with an ESD (Electrostatic Discharge) strap. This prevents static electricity from damaging the electronic components within the phone.
Wear eye protection and exercise caution to avoid cutting your fingers with glass splinters.
- Simulated Testing: Perform a simulated test. This involves disconnecting the mobile phone, connecting the motherboard, LCD, or screen with an audio cable, and then connecting the new replacement screen. Power on the device and test its functionality.
If the test is successful, you may proceed with installation. If the screen does not display correctly, contact support immediately. Do not force the screen into the mobile phone if it is not functioning during the test.
- Cable Handling: Ensure the LCD cable is not over-bent. Bending the cable beyond 90 degrees can cause a black display or permanent damage to the screen.

- Display Functionality: Check for proper image display, color accuracy, and absence of dead pixels or lines.
- Touch Screen Responsiveness: Test the touch screen across the entire surface to ensure accurate and consistent response.
- Brightness Adjustment: Confirm that screen brightness can be adjusted through the device settings.
- Proximity Sensor: If applicable, test the proximity sensor functionality during calls.

4. Maintenance and Care
To ensure the longevity and optimal performance of your new LCD screen, follow these maintenance guidelines:
- Screen Protection: Consider using a screen protector to guard against scratches and minor impacts.
- Cleaning: Clean the screen with a soft, lint-free cloth. Avoid harsh chemicals or abrasive materials.
- Avoid Impact: Protect your device from drops and impacts, which can damage the screen.
- Temperature Exposure: Avoid exposing the device to extreme temperatures, as this can affect screen performance.
5. Troubleshooting
If you encounter issues after installation, consider the following:
- Black Screen: If the screen remains black, recheck all flex cable connections. Ensure they are securely seated and not over-bent. Refer to "Tips 3: Do not over bend cable" in Section 2.1.
- Unresponsive Touch: Verify that the digitizer flex cable is properly connected. A loose connection can lead to unresponsive touch input.
- Display Anomalies (Lines, Flickering): This could indicate a damaged flex cable or an issue with the connection to the motherboard. Disconnect and reconnect the cables carefully.
- Static Electricity: Ensure proper ESD precautions were taken during installation. Static discharge can damage sensitive components.
If troubleshooting steps do not resolve the issue, it is recommended to seek assistance from a qualified technician or contact the product support.
