SAMSUNG PLASMA PS-42D4SK

[tupon79]

I have been given one of these sets with sound no picture. Can anybody help with a schematic of the power supply BN96-01217A. I do have a service manual for the set, but I guess Samsung does not want the power supply to be serviced, as there is no circuit of the SMPS. I have ascertained that I am missing VE, VSET and VS rails but it would be much easier to fault find if I had a circuit and PLEASE HELP ME WHAT IS BROKEN:sign0085:
