1. Introduction
This manual provides essential information for the installation and maintenance of replacement LED backlight strips designed for various TV models. These strips are critical components for the display illumination of compatible televisions. It is crucial to ensure compatibility by matching part numbers before installation.
Important Message: There may be several different sets of LED strips for one TV model. Always order by the specific part number to ensure correctness.
2. Safety Information
- Always disconnect the TV from the power source before attempting any installation or repair.
- Handle LED strips with care to avoid damage to the delicate components.
- If you are unsure about any step, consult a qualified technician. Improper installation can lead to further damage to the TV or personal injury.
- Wear appropriate personal protective equipment, such as anti-static gloves, to prevent electrostatic discharge (ESD) damage to electronic components.
3. Setup and Installation
Installing LED backlight strips requires disassembling the television and careful handling of internal components. Professional installation is highly recommended.

4. Operating Instructions
These LED backlight strips are internal components of a television and do not have user-operable functions. Once correctly installed, they function automatically as part of the TV's display system, providing illumination for the screen.

The LED backlight strips are sealed units and require no user maintenance. Any issues should be addressed by a qualified technician. Attempting to repair the strips themselves may cause further damage.
6. Troubleshooting
If the TV display does not illuminate or exhibits uneven lighting after installing new LED backlight strips, consider the following troubleshooting steps:
- Incorrect Part Number: Double-check that the installed strips match the original part numbers exactly.
- Loose Connections: Ensure all connectors to the LED strips are securely seated.
- Damaged Strips: Re-inspect the new strips for any physical damage that might have occurred during installation.
- Other TV Components: The issue might not be with the backlight strips. Other TV components, such as the power supply board or main board, could be faulty.
- Professional Assistance: If the problem persists, seek assistance from a professional TV repair technician.
