I did a re-cap of the analog board on my Classic II as it was having some power issues with a wavy like screen (you could see a ripple roll down the monitor slowly). Replaced all radial electrolytic capacitors, put it back in the Mac and still having issues with it. Worth noting I am testing...

Reflowing the solder is usually putting the soldering iron tip on the lead for each capacitor, heating up the surrounding solder back to a liquid state and adding a bit more solder and rosin to strengthen the bond.

Sort of sounds like to me that something has gone wrong in some of the caps in the power supply section of the board. If I had to guess it's probably either a cold solder joint or a capacitor that has leaked, bulging, or stopped working. If you are handy with a soldering iron it may be worth...
