What is a clan light?

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced.

first of all you have to check the power supply. sometimes bad electrolytic capacitors on the power supply can lead to such problems. may the capacitors seems ok visually but not be good in performance. if power supply is ok then you have to go for a ne inverter board. check the video to understand how to check the power supply of lcd tv

Testing LCD TV Power Supply BoardsSTEP BY STEP

sounds like bad capacitors on the power board. Very common problem. I would look at the caps if any appear even slightly rounded on top they are bad. They should be perfectly flat on top any puffing up means replace that cap.

This is your mainboard needing replaced! Simple as that!

The main sends the pson signal and without it...you have a dead tv.
