5. Remove Display Panel: This is the most delicate step. Carefully remove the display panel (LCD/LED screen) and place it safely aside, face down on a soft, clean surface. Avoid touching the screen surface directly.
6. Remove Diffuser Layers: Beneath the display panel, there are several diffuser sheets. Carefully lift and remove these, noting their order and orientation.
7. Remove Old LED Strips: Locate the faulty LED backlight strips. Disconnect their power connectors. The strips are typically held in place by clips or adhesive. Gently remove the old strips.
8. Install New LED Strips: Position the new beented LED strips in the correct locations. The strips come with pre-applied double-sided tape for secure mounting. Ensure the connectors align properly.

9. Прикључите напајање: Reconnect the power connectors to the new LED strips.
10. Test Backlights (Optional but Recommended): Before reassembling the entire TV, you can temporarily connect the power supply board and turn on the TV (without the display panel) to verify that the new backlights illuminate correctly. Immediately disconnect power after testing.
