When you try to turn it on, the back light will click on the then shutoff again. It will continue to do this until you unplug the TV.
I've already replaced the main board, power supply board, power switch, and the WiFi board. None of it changed anything.
Any suggestions would be appreciated
Thanks

@rich79 after you “already replaced the main board, power supply board, power switch, and the WiFi board” you got nothing left to repalce. This sounds actually like a bad backlight array. It fires up briefly but then fails and continues that cycle. For that to be fixed you will have to disasemble your TV and the panel to replace the LED backlight strips.

Replaced LED strips and still have the same results
Okay so you replaced every board on your TV and the backlight strips. There is nothing left to replace. You will have to start trouble shooting the parts you replaced. Start from the beginning by checking where the backlights get the signal from to turn on, checking if the backlights get enabled and if they receive the voltage to turn on and continue to stay on. One board, one connector at a time.

Rich did you ever get it fixed? Mine started doing the same and I replaced the power supply without success. I hate to spend more money replacing other components for nothing. Thanks.

can you direct me to a video that shows how to remove the panel and LED back lights.
I have replaced the power supply and motherboard, but no change.
I have the same exact issue. led and power light doing random stuff.

Rich, your issue matches my issue. What was the outcome on your tv? I spent an hour on the phone with Samsung India where I received no assistance. I have a Service Bulletin number but can’t find it on line. What do you think?
