Larry,
If that's a model SS2504 with a 9-1130 module.. You should post the
module number you probably would get more replys.. I would check/replace the
100uf and the 22mf in the SMPS for starters. Normally the caps it the P/S
will take care of this problem.. Did you check/replace caps in the stand by
circuits? Also check the beads some times these will cause noise..If you
need a SMPS transformer i have one in a junk set, but don't think that's
your problem.
