model number lh52bpplbs/2A

board number is samsung BN-44-00170B

2 10A 250V fuses blow instantly when power is applied.

This is directly next to the ac power input.

I have an Engineering background but it has been years since i have debugged a circuit. I can solder and have a multimeter but really have no idea what i should be testing or even how so any recommendations would be highly appreciated.

Thank you very much

I'd check those large transistors. One or more of them are probably shorted.
