Samsung UA65

[provider10]

Hi Guys
Got a samsung UA65ju6000 (possibly UN65 ) set is dead if i remove thw plug between Main and power boards, the LEDS light up.

With that plug out the voltage coming from the PSU is 13 volts (as printed on the board. When I plug in the main board this voltage drops to 9 volts.
Also , There is no stand by light .and i cannot find a 3.3 volt anywhere on the board. I also find that D201 meaasures short circuit.

I reckon the fault must be the Main Board. but any input will be greatly appreciated

Thanks James

Power board is BN44-00805a and Main board is BN94 09544B

Some pictures of your circuit boards would be helpfull. Is D201 on the main board or power supply. If on the power supply then I would replace it and then check your voltages again.
The 3.3V could be coming back off the mainboard.
