well I do have a multimeter (and have lots of experience repairing electronics), I did forget to mention when I found it, it was covered with a sticky pop like substance I think it was only on the motherboard and I took the card cage off and cleaned the whole board well it probably shorted a long time ago because of that. I did replace one of the capacitors on the motherboard. I have also check several leads to make sure there is continuity. I guess I can just start replacing the components that look corroded ot if I find any that test bad, and see if that helps, although most of these are for the outputs I will never use on the lisa.
