Ok but don't understand why C3407 is 220ufd - show 2 different schematics
with 100ufd cap in both .. however..
Since you do have 130V on HOT
PS is probably functioning enough to
start if it's getting start up from micro
and sweep chip. Usually in that case
you may have a bad sweep chip on
the control board and trouble not on
the 9-958 at all. My parts show several
different control boards either 9-968
or 9-823 but no note on either one.
I usually just ordered replacement or
exchange which is reason for no notes.
I do show one on a 9-824 that
had a bad sweep IC which wouldn't
let the set start.
