Our Sony KV32S22 (12/97) went dead, is there a fuse or reset?

It just shut off. One minute perfect everything the next-nothing at all. I'm an A/C contractor that has recently repaired a washer. The internet is growing
on me. I'm hopeful that you folks out there may be
able to lead me to a fuse or reset button. I'm not really expecting anything that easy, I really don't know where to begin and have heard that you can
get knocked on your butt. I do have some electrical
background and am familiar with my volt ohm meter.
Any sugestions.
