Yes, I know how a switching mode power supply works, I was an EE in a
former life. Interesting layman's descriptions you used: "getting rid of
frequencies", "the caps are filter based". The big cylinders are the
smoothing capacitors after the rectifiers. You would really get a big
bang out of those and lots of smoke if they went. More likely the
rectifiers or the switching transistor has gone and taken the fuse with
it before any damage could be done.
Sometimes the demise is silent: the resistor that provides the startup
current goes high and the PS quietly stops working.
Repairing a SMPS is best left to skilled people with too much time on
their hands.
