75" MU8000 Series 8 TV - flickering and black screen

[Members_XsSHTlN]

Intermittent flickering and screen going black. I've tried turning off ECO settings,  lowering the brightness, and performing a factory reset. I was hoping the problem was isolated to the One Connect box, however it happens when using Apps installed on the TV as well. When disconnect the One Connect box, the TV  is unusable and displays a graphic that it needs the one connect box.

Could replacing the One Connect Box possibly help?

Is there a common fix for this issue?

Likely the backlight failing. Happened to me on a less than 1 year old Samsung TV.

Love their phones and tablets but their TVs appear to have consistent quality control issues.

Thanks for the reply. I've seen backlight kits for cheap, so I may try this repair.

Can anyone else confirm the backlight is probably the culprit?

To elaborate, the backlight could be failing do to other underlying issues like bad power supply, improperly connected connectors that have melted. It's a rabbit hole. If you're comfortable working on the TV, open it up first, inspect for obvious issues and use a multimeter to check voltages.
