[chuck]

hoping someone out there has this schematic Toshiba T.V. model 20A43 chassis
# M3M914 set turns off all by its self with no consistent time after being
turned on came into shop with a blown H.O.T. replaced and set works great
except for the new auto off feature. I need the schematic to conduct some
voltage tests any help will be appreciated
thanks Chuck

Waited as long as I could, no one posted a reply.... So I bought the
required info from Toshiba
Cheers

FYI
the problem of consistant auto shut off at random times was traced to the
Xray protection circuit a bad Q503 was tricking the protection circuit into
the shutdown.... just thought some inquiring minds might like to know
