Don't replace it until you're sure that's the only thing that's gone. That's exactly how I'm (trying to) handle it. I don't have any problem replacing anything that tests bad; but, just throwing parts at a problem isn't what I'm trying to do. Of course, that means I need to look closely at the circuit board, as that's the first step of any diagnostic procedure. Looking at the BOTTOM of the circuit board, I find something interesting at each end of the electrolytic capacitor leads: http://farm4.staticflickr.com/3677/1...1c6ff9ec_o.gif It almost seems as if the capacitor overheated, but, it it not an open circuit: http://farm8.staticflickr.com/7397/1...a5301efd_o.gif It actually looks like someone has replaced that electrolytic before. Oh yea, looking at your other pictures, it now looks like the board was manufactured in 1998. ^_^ TDD |
