Here is an update. I substitute the Tuner's IF signal from another good tuner but the result is the same--vertical rolling. Guess Im close but still not on it yet. Help appreciated. |

Is there a coupling capacitor in the video path? If there is, it is probably gone down in capacitance, and is rolling off the low frequency response. -- Service to my country?
