60's color motorola

[rob Cashin]

the signal is good, i use my converter box and vhs/dvd daily on my 80's zenith space command. i got the tv going again, a tube was half out... the tuner is screwy. i get no picture but then if i push on the tuner to the right it comes in nice and clear, but black and white

Did you adj the fine tuning per my video? Try it while doing what ever you are doing to get a BW pic

the idea here is to isolate the color issue to tuner bandpass or color circuits.
