Just to let you know i went a head an ordered a board. This concludes that the panel is broken for the sake of curiosity. Now i just need to sell the working parts off Ebay.

Thanks for the reply. I already did that and there was no backlight.

Hi All,

Need help.

I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.

So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard....
