Hi eddy2023,
Your tv backlight strip is fault. You have to buy new set.

Mistake. When you turn it on, the tv comes on and then turns off again. The background lighting comes on briefly. Power supply: BN 44-00633B

Hi,
You will try disconnect maionbord power supply cable, and plug AC power to power supply board.
Backlight works?

Hello,
yes also have mainboard completely disconnected. Error is the same... Power supply turns on and after a second turns off. and so it repeats. on,off,on,off.
Backlight also goes on off on off.
I think either something is wrong with the power board. but I have not discovered anything. have re-soldered everything.
think the protection circuit jumps in. that's why it goes off immediately. then on again.
but I can't find a circuit diagram.
Have made video. Here is the link.

I disconnected the LED strips and plugged them into the lab power supply. Tested with lab power supply. All LEDS were equally bright...

Did you break the display? Because one of the LEDs may be short-circuited, which is not visible on the display, but the electronics will prohibit it. Measure the voltage on each segment, at constant current, it should be the same.
