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
