JCPenney 5060VHS VCR tope loader

Yea it's lower end 2 head mono VCR. I did swap two of the boards with the ones out of the parts unit it made no difference. If I'm going to continue on this project I need a service manual. So I went a head and purchased a Sam's photo fact for the model 686-5060. Hopefully with that and the troubleshooting chart I can get the VCR fixed. On the front of VCR it just says 5060 and when I was creating the title for the forum I just quickly looked at the front of the machine.

Molded plug disease is where the vinyl reacts with the copper wire making a green goo that seeps out of the plug. if you cut the cord off you can see green goo around the copper wire. I have seen it on stuff from 70s an older but never anything from the 80s. The goo was on both of the JCPenney VCRs (OEM Panasonic) so I would keep an eye on Panasonic stuff from mid 80s as there power cords maybe starting to fail do to age.

I've never heard of that before. Does it happen in certain parts of the country / world and not others? Maybe like near an ocean?

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.
