Hello, I'm Shahid and need additional info about TV symptoms as follows..

Does power light on TV lit or blink when push power button to turn it On?

Was there any storm in area that might caused this problem in TV?

These info will help to troubleshoot the problem.

OK, does TV screen glow/ show backlight or any graphics appears on screen?

Thanks for the info.

It seems main board failure in TV and replacement of main board will help to resolve the issue. There are various different part number/ versions of main board utilized in this model (32LH20) and it needs to check what part number main board is utilized in your TV so please check following link to view the video clip about part number verification then check following board supplier to see when they can provide required main board as currently they have it out of stock..

If you are not comfortable working on it yourself then you may please use following link to get list of TV repair shops in area which will help to get repair quote...

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue. I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV. Please feel free to respond if you have any additional questions.
