persistance.........i got lucky and found a link which referenced the company. The part in the link was not the part i was looking for but i searched the company's site and there it was. Trust me i tried just about everything: Forums, calling major electronic distributors...

Using a multimeter i ohmed out most of the inverter board. I noticed one of the caps looked "different" so i started testing devices in that region. A cap is bad (easy to replace) and the two devices i mentioned are bad and one of the transformers is bad.
