SMPS Board for Samsung 42 inch Plasma TV Can't Post

Hi there,
Im trying to service the SMPS board on a plasma Samsung S42AX YD01 chassis. The two power FET IC switches blew at switch on and I would like to find out what caused this before I replace them in case it could happen again. The trouble is that I cannot find a circuit diagram for the SMPS board (reference LJ44-00092C). Does anyone know where I can locate one? An interesting thing about the result of the failure is that there is still a watchable picture on the screen although it has a slight greenish hue on the highlights and there is a black patch in the top left hand corner of the screen. Grateful if anyone has any suggestions. Thanks. Butch

Thanks, JTS1957.
Today was the first chance that I had to get back to the job. Unfortunately, however, the downloaded data does not appear to match the version of my board. I'll simply have to go back to tracing the circuit out from the blown FETs.
But thanks for your help anyway.
