Replacing LED backlight strips requires careful disassembly and reassembly of your television. Proceed with caution.
- Preparation:
- Ensure the TV is unplugged and cooled down.

7. Troubleshooting
If you encounter issues after installation, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No backlight / Dark screen | Loose or incorrect cable connection; faulty power supply to strips; damaged strip. | Check all connections to the backlight strips and the power supply board. Ensure strips are correctly seated. Inspect strips for visible damage. |
| Flickering backlight | Loose connection; incompatible power supply; faulty strip. | Verify all connections are secure. Ensure the power supply board is functioning correctly. Isolate and replace any flickering strips if necessary. |
| Uneven brightness / Dark spots | Improperly seated diffuser layers; damaged individual LEDs; incorrect strip placement. | Re-check the placement of diffuser layers and the LCD panel. Inspect individual LEDs on the strips for damage. Ensure strips are evenly spaced. |
