You can replace the IC, but it's a difficult job due to the heavy circuit board traces. I've also had mixed luck getting good replacement ICs. I would recommend replacing the whole board if you can find one.

Thanks, Although when I looked at the panel (although I wasn't looking for it though either) it didn't seem like it said anything about LG on it, so maybe it is just a bad fuse? Or I guess I could just search on ebay and see if I can find that Y-Sustain Board and see if I can a replacement for cheap enough.
