• Avoid touching the components on the board directly with bare hands. Hold the board by its edges.
• Ensure all connections are secure and correctly oriented before reapplying power.

5. Setup and Installation

Replacing a monitor main board requires careful attention to detail. It is highly recommended that this procedure be carried out by a professional technician.

1. Preparation: Ensure the monitor is completely powered off and unplugged from the wall outlet. Place the monitor face down on a soft, clean surface to protect the screen.
2. Access the Main Board: Carefully remove the monitor's back cover. This usually involves unscrewing several screws and gently prying open plastic clips.
3. Disconnect Cables: Take photos of all cable connections before disconnecting them from the old main board. This will serve as a reference during reassembly. Disconnect all ribbon cables, power cables, and signal cables.
4. Remove Old Board: Unscrew the mounting screws holding the old main board in place and carefully lift it out.
5. Install New Board: Position the new main board in the monitor chassis, ensuring it aligns correctly with the mounting holes. Secure it with the screws previously removed.
6. Reconnect Cables: Refer to your photos and carefully reconnect all cables to the new main board. Ensure all connections are firm and correctly seated. Pay special attention to delicate ribbon cables.
7. Reassemble Monitor: Once all connections are made, carefully reattach the monitor's back cover. Do not force it; ensure all clips and screws align properly.
8. Test Functionality: Plug in the monitor and power it on. Test all functions, including display, input switching, and menu navigation.

6. Operating the Monitor (Post-Installation)

Once the main board is successfully installed, the monitor should function as intended. Operate your monitor according to its original user manual for display settings, input selection, and other features. The main board facilitates these operations by processing signals and managing internal monitor functions.

7. Maintenance

• Cleaning: Keep the monitor's interior free from dust. If the monitor needs internal cleaning, disconnect power and use compressed air or a soft brush. Do not use liquid cleaners directly on the main board.
• Environment: Operate the monitor in a clean, dry environment, away from extreme temperatures and humidity, to prolong the life of the electronic components.
• Handling: Avoid dropping or subjecting the monitor to physical shocks, as this can damage internal components, including the main board.

8. Troubleshooting

If you encounter issues after installing the main board, consider the following:

• No Display/Power: Double-check all cable connections, especially the power supply to the board and the display panel. Ensure the monitor's power button is functioning.
• Incorrect Model Match: Verify that the replacement board's model number (e.g., BN41-02118E) is compatible with your specific monitor model (e.g., LS24D300). While some variations may be functionally identical, exact matches are always preferred.
• Faulty During Shipping: If the product appears faulty immediately upon receipt or after installation, please contact the seller immediately. All boards are 100% tested before shipping.
• Minor Cosmetic Issues: As these are used boards, minor scratches or dust are normal and do not affect functionality. Do not open a dispute based solely on cosmetic condition if the board is working.

9. User Tips

• Verify Compatibility: Before purchasing, carefully read the product title and description to ensure the board model (e.g., BN41-02118E, BN94-13067B) matches your monitor's model (e.g., LS24D332HSX/ZD, S22F355FHL-XZS).
