I know I'm resurrecting an old thread here, but I'm curious what you ended up doing? I successfully resurrected an S750 by replacing a bunch of old Capxon caps with nicer Nichicon and Panasonic caps (at the suggestion of this board here) and it was working for several months but then I heard a loud *pop* and have a scorched board in the same area. However my problem is the radial 47uF 25V cap next to the blue cap. The pop blew off one of the legs in fact (you can see pics of it here). Oddly enough, it was one of the capacitors I had replaced, though looking over my work I don't think I did a bad job. =/
Did you ever get it working again after replacing that capacitor? Have you checked the radial next to it (yours is still covered in heat shrink). Come to think of it, though I don't recall mine being covered in heat-shrink before, but could not covering it have caused it to blow? Amateur question, what's the reason for the heat-shrink? I notice a few capacitors are covered by it but not for any discernable reason.
Last question, do you know the board number of that capacitor? Part of my pcb mask was corroded by old glue and the number came off with it during cleaning.
