Topic 1 / 3
TV backlight replacement
If the screen goes dark, you see only shadows, or one half lights up and the other doesn't — the backlight is often the cause. The technician checks LED strips, the backlight driver, and the power supply.
Replacement involves partial disassembly of the case and panel. We explain the scope and agree on the price before repair starts.
