This is very good looking. Looks like you now have a light weight less expensive

If you apply that signal to the plate of V1 with the coupling capacitor in place
you might be able to pass the signal through the IF Coil A6, it should be tuned
to that IF frequency and pass the signal. Not sure of any other way to be sure
that coil is actually "Good" as far as passing the signal, Even though the ohms
might read ok.....
Other than that, you will have to go through all those parts around V1 to find
the problem.....

Anyway, looks better than I expected. I'm not sure, but it even looks like
that girl may even have red lipstick on, or it's just my wishful thinking....
If there is - well then it's tuned well enough to pass burst signal too....
I would not turn anything till you can get this set working from it's own tuner.....


You know.... I wonder if you took the iF plug from this tv's own tuner, and jumped
it ahead with a coupling cap, to that V2, if you would see the same results....?

It would also rule out the tv's own tuner as a source for trouble......

You guys have done some good work here......
