Default Re: Samsung un49mu7000f dead no power

I have replaced the main board with 2 different replacement boards from TV PARTS TODAY and also replaced the power supply board once with no change.
(Am I getting defective boards from TVPARTS TODAY? They’re supposed to be fully tested before shipping)

I’m a little curious to why I’m not getting the 3 VDC standby voltage.
I’m just not sure what voltages I’m supposed to be getting on CNM 803 as they aren’t marked on the PS board.
