Nope , there are OK. Also , the main board is not under the tubes.

Where can I get the service manual for this model ?

Tks..


i would say the tech must be out of his league.
kind of sounds like the old techs from the old
school around here!

more than likely a power supply issue ! wheather it
be a fail safe trigger from a problem in the HV section,
or component shorted else where or! the supply it self
went south in which case, you may want to check for the
health and welfair of the electro caps..!
i found a switching PS once that wouldn't start up
and it was due to not a low/failing cap losing its value
but for some reason it created an high ESR that was showing
a ripply on the line on start up even thought the cap checked
ok.
