No reply to this request? If someone could check resistance from pin 26 to
pin 30 on a micro on just about ANY Toshiba tv it will probably tell me what
I need to know. Kevin from Tritronics called me and he will take care of the
part problem for me. He says the used part came to them from Toshiba and I
don't doubt that at all.

I'm sure the microprocessor IC is bad, IC QA01 M37274MA-054SP. Pin 30 reset
has an internal short to ground pin 26 of about 62 ohms. Ordered it from
Tritronics and after waiting about six weeks they sent me a used one that
someone pulled from a board and it has the same internal short, I installed
it to verify that the set still does not work. Can someone check the micro
in a Toshiba set and see if I'm right about this being an internal short?
The base generic number on the IC is M37274MA and any chip of this family
should read the same ohms pin 26 to pin 30. This is the second time
Tritronics has sent an obviously used part, are they picking on me? Thanks
for any help.
