already have SM. Not much help after I diag which PCB is defective, no individual schematics.
TV has 2 inverter boards, master and slave. Does this TV need both? How do I know which is dead?
Done some looking, apparently its common for these inverter PCBs to die, sooo now what?

heres what these parts look like...
