I checked all the green fuses, and they are good. Don't know how to check the transistors.Leave a comment:

X-main here is the other bad cap, between the fuse and the bigger 250v 68uf cap. I already took it out waiting on the new one. Luckily I ordered two one for a spare, then I found the other one blown on the y-main tonight....Leave a comment:

I also was checking the fuses for power and were the main power wires come in there are two fuses one on each side of the plug. The one on the right has 122.7 ac volts and the one on the left has .708 ac volts is that normal or should both have 120 volts?Leave a comment:

I tried that and it would only save one pic at a time. Don't know if its because I'm using my I pad. The chips look good I can't find any burnt spots or holes in any of them. Just the bad caps so far on the y and x boardsLeave a comment:
