Huawei Watch Fit 3 AMOLED Display and Touch Screen Replacement Manual

1. Introduction

This manual provides comprehensive instructions for the installation, operation, maintenance, and troubleshooting of the 1.82-inch AMOLED LCD display and touch screen replacement part for Huawei Watch Fit 3 models SLO-B09 and SLO-B19. This replacement part is designed to restore the visual and touch functionality of your smartwatch.

2. Setup and Installation

This product is a replacement component and requires careful installation. Professional installation is highly recommended to avoid damage to the part or your device. We will not be responsible once the screen is installed incorrectly.

Before Installation Notes:

1. Test Before Installation: Do not remove any protective film or tags before testing. Pay close attention to static electricity. Before attempting any repair, ensure you are grounded with an ESD (electrostatic discharge) strap. This prevents static electricity from damaging electronic components. Wear eye protection and use caution to avoid injury from glass splinters.
2. Simulated Testing: Screen replacement is a very fragile product. We strongly suggest testing before full installation. Simulated testing means disassembling the device, connecting the motherboard and the new LCD/screen, powering it on, and verifying functionality. If the test is successful, proceed with installation. If it does not display correctly, contact support immediately. Do not force installation if the test fails.
3. Do Not Over-bend Cable: Ensure the LCD flex cable is not over-bent. Bending it beyond 90 degrees can cause a black display or permanent damage.

3. Operating the Display

Once correctly installed, the AMOLED display functions identically to the original screen of your Huawei Watch Fit 3. It provides vibrant colors, deep blacks, and excellent contrast. The capacitive touch screen allows for responsive interaction with your smartwatch's interface.

• Touch Functionality: The screen supports multi-touch gestures for navigation and interaction.
• Display Quality: Enjoy the high resolution and color accuracy characteristic of AMOLED technology.

4. Maintenance

To ensure the longevity and optimal performance of your new display, follow these maintenance guidelines:

• Cleaning: Use a soft, lint-free cloth, slightly dampened with water or a screen cleaner, to gently wipe the display. Avoid harsh chemicals or abrasive materials.
• Protection: Consider using a screen protector to guard against scratches and minor impacts.
• Avoid Impact: While durable, the screen is still glass. Avoid dropping the watch or subjecting it to strong impacts.
• Temperature Extremes: Do not expose the watch to extreme temperatures, as this can affect display performance and battery life.

5. Troubleshooting

If you encounter issues after installing the replacement screen, consider the following troubleshooting steps:

• No Display / Black Screen: Recheck the flex cable connection. Ensure it is securely seated and not over-bent. A bend exceeding 90 degrees can cause this issue.
• Touch Not Responding: Verify the touch screen digitizer cable is properly connected. Ensure there are no debris or obstructions between the screen and the watch frame.
• Flickering Display: This could indicate a loose connection or a damaged flex cable. Re-seat the cable carefully.
• Device Not Powering On: Ensure the battery is connected and charged. If the device still doesn't power on, the issue might be beyond the screen replacement.
• Professional Assistance: If problems persist after basic troubleshooting, it is recommended to seek assistance from a qualified technician.
