Hello

Welcome

We do have back-light problems with LG sets however the first thing to check as an elimination exercise would be the power-board, are you able to do work yourself with the set?what it will amount to is possible replacement of a board or after some checks are made a conclusion drawn.

Let me know please I will provide more help.

About how much are the power boards ?
Expert:  Anthony_Infotech replied 6 months ago.

Board will be around $100

I must convey to you though we have had a lot of LGs with failed LED backlights and that is not an option to fix, the powerboard has the LED driver attached but obviously if the lights themselves are bad then its bad news and there is no effective way to check

Let me know

Anthony

PS please remember to rate positive thank you
