Found it! And indeed the power filter has 120V coming in and nothing coming out. The weirdest part is it has a small fuse (glass cylinder) that is soldered to the board and then epoxy'd over. I guess its a fail safe but still odd, why isn't it replaceable. If they dont make me send it back (still under parts warranty) I'm going to dissect it and see if it blew.
Ordering the part from LG now....keeping fingers crossed!
