I fixed several power supply problems by opening it up and noticing that there
is a footprint on the PC board where a filter *would* normally be installed,
usually just jumpered over with bare wire. About 10 turns of something like 18
or 20 gauge insulated wire, bifilar wound around a torroid would work in place.
Just make sure to wire it correctly (in-line) so you don't short out the AC
