Your C107 is a 6.3 V spec. (I can see by the one on the 3.3 V board - not an issue there.) I had one blow early on and it took out a few other things on the 5 V SMPS. I repaired it, but testing showed continued problems. I bought a new set of SMPSs from Hans and I've had no issues since. Hans went to a 10 V spec C107 later and I haven't heard of more problems like yours. I believe some of the 6.3 V spec ones were more like 5 V and that's why it blew.?
Anyway, there is a good chance that something else is damaged, hopefully only on the PS boards. As recommended by others, check the Vdd and Vss and +12 V resistances after you remove the SMPSs. If those resistances are good, then I would recommend you simply buy a new pair of SMPSs from Hans rather than try to repair the ones that are damaged.?
