That picture attachment of injected video at TP B is really nice & looks better than
the earlier pics.... I don't see any problems with the circuit components from
that point on. I guess it's still forward of that point. That leaves IF &
Detector, anything before TP B. This tv & it's problems sure are
illusive.... The negative looking picture bugs me. I think a number
of years ago someone on here had a 21xx55, I forget now the
full chassis, it was the first 21" with the chassis from the
15GP22, and if I recall correctly that person had a
negative or very faint picture, & he was thinking
it was a problem around the detector diode.
Anyway I don't recall it all that well, & Can't
find it. You may just have to go through
each little nook & cranny of the IF
strip & recheck everything you
already did..... I don't have a
good idea on where to go now.
I never had to do a full alignment on a TV IF, so you might just
have to invest in a scope & alignment marker generator to
figure this one out..... The thing is, how cold it have got
so far off to look like it does now?
