If I am thinking of the right chassis, I have only
seen one with an actual large signal failure, and
the rest have all been flaky SSB boards. This is
the little board in the SIMM socket near the right
side of the set. In the case of the alleged error 2,
it has been a shorted input pin on the microprocessor,
the pin that receives the vertical pulse. These
little boards, which are the brains of the set, seem
to be chronic failure items. Of course there are
some SMD resistors, capacitors, and a transistor
that "condition" the signal before feeding it to
the SSB, but the signal path seems to always be okay.
And of course, the SSB is hard to get at and diagnose.


You were right. A new SSB board fixed the problem.
