Don't just throw parts at it. Test the parts and only replace them if they are bad, or if they are something you are unable to test and you have tried everything else. Each time you replace a part, you create the opportunity to error. Wrong part installed, part installed the wrong way around, part that needs to be insulated from a heatsink installed without insulation, part that uses the heatsink as a connection installed with insulation, solder bridge created, damaged traces. These are all things I've seen when cleaning up after previous repair attempts, and in most of those cases I spent longer correcting errors that were introduced by the previous repair attempt than it took to fix the original problem.

Even if you want to replace all the electrolytic capacitors which is not a bad idea, get it working first, and then go ahead and replace old but functional parts as preventative maintenance.

Is there a full schematic of the analog board online somewhere? I sold my last pre-SE compact a while back so I don't have a board to look at.
