Just Picked up this UN46EH6000 TV that has a BN44-00498A Power supply, nothing happens when power button is pressed moments later a slight clicking sound can be heard. Back lights will not turn on when unplugging the connector to the other board. I seem to have all the voltages on the hot side. At CM803 I only have 5V on pin 12 and 3v on pin PS_on (other board unplugged). all non surface mount diodes are good, capacitors CM851, C9110, CS855, CM875, CM858 removed and tested good. Someone have an Idea of what could be the cause, do I need to 'activate' PS_on to see other voltages? Is PS_on looking for a ground? or 5v to turn on rest of the board voltages.
Attached is the schematic to help figure it out, the number is slightly different but seems to be the same from what I can see and is easier to read.
