I realize that this thread is somewhat old, but it's the only one I could find when I searched for JVC JR-S400. I've had this stereo for a while now, it was actually passed down to me from my dad (came with some pretty nice Polk Audio bookshelf speakers too). Just recently, though, the unit began smoking and stopped working. I had someone at the house to do some painting, and I was in my room (other side of the house) with the door shut. I smelled something burning so I bolted for the living room to find this jackass painting away while my stereo receiver is over in the corner billowing smoke! Obviously I wanted some kind of explanation, so I ask him why he didn't come and tell me my stereo was on fire. He said that he didn't know that I was home, but that he had unplugged the unit to move it so he wouldn't drip paint on it. He then said he had plugged it back in once he had finished that area. This whole time the unit was on. The receiver no longer works, and I'm bummed that all I have are my laptop speakers now. My question is for experienced owners of this model: What could have caused this (and much more importantly) where do I start with diagnosing the issue and resolving it? I suspect that the issue is with the black box (am I guessing right that it's a power supply?) shown in the picture below (OP's picture, using it for reference). I felt that box immediately after I unplugged it and yanked the cover off, and it felt very hot. Anyway, I'd love to be able to resurrect this thing because I love the crap out of it so any help would be greatly appreciated.
Thanks,
Henry
Ok nevermind, apparently I'm too much of a n00b still to be able to post pictures, so reference OP's third picture to see what I'm talking about.
