I wonder if somebody removed / replaced the head drum and reinstalled it 180 degrees off. A classic symptom is no color (azimuth angle is slightly different between the two opposing heads), and those black streaks are a symptom of bad heads.
Another common cause of generally crappy video in Panasonic-built VCRs are those ceramic modules. One that handles video processing is likely bad. They were about $ 40.00 back in the day. Probably NLA by now. |

I actually believe I can solve the problem. I own a PV-1220 and there is a video board near the coaxial ports. When I first bought it, it had the exact same problem. It is quite simple actually to repair. You need to locate the chroma potentiometer and spray it with contact cleaner. Spray and adjust until you have color. Also spray the channel 3/4 switch as that often becomes corroded, resulting in signal appearing and disappearing at random.
