In this video we will show how to replace the LED strips in certain LG TVs.
This is a generic tutorial, and if your TV model is listed in the video description, the general process shown in this video should apply to your TV, even if there are some small differences.
When replacing LED strips, you will have to remove the panel.
Removing the panel can be very difficult. If your TV panel is damaged during the replacement process, you will have to get a replacement TV.
Start by removing the screws and the back cover off the TV.
Disconnect the cables to the speakers and set the speakers aside.
Disconnect the cables to the t-con board and to the scan drive boards. Remove the screws and the plastic cover over the t-con.
Remove the screws on the metal covers that are over the scan drive boards.
Remove the screws for the TV bezel.
Adjust the tabs and remove the metal covers.
Release the scan drive boards.
When releasing the scan drive boards, disconnect the ribbon cables on the scan drive board. These cables are the ones that connect from the scan drive board to the t-con board.
Remove the remaining bezel screws.
Flip the TV over and remove the bezel.
Flip up the scan drive boards and tape them to the TV panel.
Release the tabs and tape on the side of the panel to release it from the chassis.

Using a five in one tool, or something similar, remove the LED strips.
It may help to use a five in one tool and something to push the tool from the back.
Install the replacement LED strips. They may be sticky on one side, but we will use some double sided tape, just to be sure they adhere to the chassis.
It may happen that an LED lens gets knocked off when installing the LED strips. If this happens, and you need to use that strip, you can use super glue or hot glue to put the lens back in place.
Install the replacement LED strips and reconnect them to the cables. Be sure they are properly aligned.
