Introduction

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:

42LY340C-UA BUSWLJR 42LB5600-UZ BUSWLOR 42LF5600-UB BUSYLOR 42LF5600-UB BUSDLJM 42LF5600-UB AUSYLOR 42LF5600-UB BUSYLJR 42LF5800-UA BUSYLOR 42LX530S-UA BCCYLOR 42LX330C-UA BUSYLOR

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.

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.

How do I change the LED strip on my LG TV? In this tutorial, we’ll teach you how to replace the LG 42inch LED TV strips.  This tutorial will work with a wide range of LG 42inch LED TV models, even though these models may vary somewhat from one another. These LG 42lb5600 Screen Replacement Steps that we are demonstrating should apply to all of the models.
