Hi everyone,

I have an issue with mine SAMSUNG UE75NU8002. TV in not able to boot correctly, this looks like the power supply issue, but I am not sure. Maybe someone know how to decode blinking LED signalizator?

After connection TV to power supply, screen comes to be lightened but after few seconds it turns off and run into rolling reboot cycle. There is short "click"sound before that.

Does anyone have idea, by watching blinking, if this is power board issue or maybe something more serious?
I have recorded behaviour and pushed into youtube:

Two flashes and backlight up briefly and then a reboot is more than likely the screen. It can sometimes be the main board, but nine times out of ten is the panel.

Ohhh That's what I feared. Any idea if I could confirm panel demage with electric multimeter?
