Hello guys
I am here because of the youtube post you did on the BN44-00502A
I have an UE40ES5500 with that powersupply board

When switching on it shows the smarttv logo and than reboots.

I've tried a couple of things
Disconntect mainboard from power board. Backlight also comes on but turns off. The interval between on/off is much faster then when it's connected to the mainboard
Disconnect powersupplyboard from backlight. TV starts up. There is sound but offcourse no picture.

On a different forum they said that the problem was probably the backlight. But could this be the fault of the powersupply board?

With regards
