Have TV Questions? Ask a TV Technician

- 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?
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..

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.
