check the 2 fuses on the left of the backbox directly above the giant capacitor, If you replace the fuse and it blows again you probably have to replace one of the bridge rectifiers screwed to the cabinet in that same location. the youtube link below gives instructions for testing the rectifiers.

if you have to replace the rectifier just match the part # on digikey.com these are fairly standard parts

good luck! and GREAT SCOTT!

wow, I think I have 8A fuses in both those slots... you might want to check the manual for the fuse rating before you power it up again. That would stink to fry something permanently because your fuse rating wasn't right

I thought I remembered that a light stuck on was a bad transistor, but i'm no expert.

ton of info in this writeup, including the issue with the logic driven lights you had pre-fuse replacement.
