Introduction
Go to step 1 ↓LG makes some of the finest LED TVs you can buy. Thanks to features such as the excellent webOS smart TV platform with connecting to the router and the superiority of OLED panels. It also offers some of the finest picture quality, sound, and smart capabilities available in any 4K TV on the market.
However, when it comes to replacing or reinstalling LED strips or arrays, people usually approach a TV repair technician. Yet, you can do it by yourself at your home.
This repair guide will work with the following models:

42LB5600-UZ BUSWLOR
42LF5600-UB BUSYLOR
42LF5600-UB BUSDLJM
42LF5600-UB AUSYLOR

Backlight LED Array
A Backlight LED Array is a long circuit board containing surface-mount device light-emitting diodes (SMD LEDs) that radiate light into a room to provide illumination. The strips are sometimes referred to as LED tape or ribbon lights, and they typically include an adhesive backing that makes them simple to install.
LED light strip options that are among the finest available may be utilized for various interior design projects, including recessed lighting, television backlighting, and kitchen countertop illumination with under cabinet lighting.
In this tutorial, we are using these backlight LED Arrays to replace the LED strips of the LG 42inch LED. These LED strips are chosen for their high level of quality, usefulness, and visually appealing design. Other factors considered are the adhesive strength, app functioning, brightness, and simplicity of installation, and how well the light strips functioned in general terms.
How much does it cost to replace LED strips on TV?
It costs between $100 and $125 to replace one LED backlighting strip, including all necessary components and labor. Repairing older TVs is more expensive. Parts for these televisions may be difficult to find. Additionally, components for televisions with a screen size of 42" or larger are costlier.

Tv Lg 42lv3500 no se ve imagen , lo único que se ve son líneas de color verticales y luego van desapareciendo hasta quedar en negro , me podrían ayudar por favor
No one ever shows how to get the wire adapters off the ends of the LED strips! Also, the spacers are very brittle, if you put a 5 in one under it, it will break. Take them off from behind and just push it in a little where the catch is and slide it gently on the face side.
My Tv is blank (not showing picture but has a black light display instead of pictures) but still plays sound loud and clear. What could be the problem please? “LG 43" smart. Model 43uk6400plf. Firmware 5.50.15”
Mine has the similar situation, no picture shown most the time and whenever picture is on, left half of the screen is flickering with white stripes （on and off) , I thought it might be the display controller's problem but not sure, will someone could guide a direction on how to fix it?
