VIVAX Imago LCD TV-3215 - SLT689 Power board

[kixo]

I'm trying to replace some resistors on power board from VIVAX Imago LCD TV-3215, but I can't identify them because they are badly burned.
They blew up after near lightning strike . Any advice on how to identify them?

MODEL: SLT689
VER:1.0

Already searched for board replacement, no luck.

All I can say is the total resistance will be less than 1 Ohms for the Source resistor.
Did you check MOSFET Q11 to see if it has very low resistance between Source and Drain pin.
You also have bad caps on the cold side of the circuit.
