Sharp TU-95PA Black & White 12"

Hi guys,
This is my first post here. I am a longstanding member over at audiokarma and have had great luck there with my audio projects. Hoping someone here can help me with my little B&W set. It has been working all these years until about two weeks ago when I remove the back to blow out the dust. Afterward, I turned it on with the back still off to make adjustments to a couple things that are covered when the cover is on. I accidentally touched two terminals (I think) on the power switch with my watchband. There was a small spark and the set went dead. No picture, no sound. I'm puzzled because it looks like all of the tubes are still on. I can't seem to find any fuses so I don't know what to check. Any help would be appreciated. I purchased the SAMS manual, but I don't know where to start. Thanks in advance!
