No, I wasn't looking for a magic fix, but rather some ideas that I could maybe try. I'm not an expert, so I don't even know what it meant by trying the "caps". Why the cynicism?

Well, you could try unplugging it for a few hours, but I cannot see this doing any good. > I'm not an expert, so I don't even know what it meant by trying the > "caps". Caps are "capacitors". Although they're made of a variety of different materials, the ones that are typically troublesome are known as electrolytics. They contain a roll of thin metal foil and a moistened paper inside. They usually look like cylindrical cans of varying sizes. Some overworked, cheap or improperly made capacitors fail when the paste dries up. Sometimes such capacitors look defective (tops or bottoms bulged out, leaking paste, etc) and sometimes they do not. New electrolytic capacitors are cheap, and if you replace the bad ones soon, your equipment can be brought back to life. You'll need a soldering iron, something to desolder with and of course, some new solder. > Why the cynicism? I think it's because you asked in a newsgroup dedicated to the repair of electronic devices and then expressed a total lack of interest in fixing your equipment. But that's just a guess... :-) William
