I've attached a copy of the service manual.

Nobody (?) can see it. This is not a binary group.

Better to upload your manual to a file sharing site and post a link to
it.

Pages 8 & 9 suggest that you have an IK (AKB) fault.

IK = cathode current (?)
AKB = automatic kinescope bias (automatic colour/white balance)

The manual points to a possibly faulty M board, or misadjusted G2
setting. If yours is an old set, then I'd suspect a tired CRT.

"If the RGB levels do not balance within 2 seconds after the power is
turned on, this error will be detected by IC001 (M Board). TV will
stay on, but there will be no picture."

I'd be looking at the C board on the CRT neck, specifically IC702.
IC702 provides IK information to the M board.

Here is the datasheet for IC702 (TDA6108JF):

Thank you Frank for you advice. I will examine the IC702 datasheet you
mentioned. I don't know if my voltage reading were of any use. it
seems bizarre that the rectifier right off the mains input would not
output higher voltage coming right off 123v.

I'll keep you posted. Thanks again.
