Capacitor advice needed

[rensjepensje]

The pictures don't show the bloat, and the residue is most likely from manual touch up soldering. I don't see how the white stuff on the second picture (reverse side of board) could come from leaking caps since it's on the other side of the board.

My point is, if you haven't measured the cap and found it to be bad, don't jump to conclusions!

I guess you were right. I replaced all the caps. But the leds still don’t work as they should! I do believe the hum is gone though!
