Hello and Welcome. My name is ***** ***** I'll assist you today. I'm sorry you're having trouble with it. I need additional info to troubleshoot the issue.

- Is the backlight flickering or the picture?

You can check the backlight flicker at rear of display panel as white bright light would be coming out of any vent holes to determine if it is flickering?

It's definitely the backlight
Expert:  Shahid replied 1 year ago.

Thanks for the info, this kind of problem occurs due to failing main board of TV where main controller chip is mounted that controls all the functions of TV including backlight control. Have you replaced main board of TV?

Please check with following supplier to get replacement main board as per part number found on main board installed in TV..

I trust my input will help you out. Please feel free to respond if you have any additional questions.

I thought backlight control ran through the t-con board ?
Expert:  Shahid replied 1 year ago.

No, t-con board only provides video data to internal circuitry of display panel to make an image/ picture, it gets video data from main board.
