Zenith Model VR 3220 4-Head Hi-Fi VCR having Video Issues

[TUD1]

Interesting. I've seen many a Panasonic made machine have a similar problem that was due to bad electrolytic caps in the power supply. But I've never seen a problem like this on a JVC. JVC machines of this era are usually tough as nails.

I used a head cleaning tape once back when I was just starting out in VCR's. The picture looked twice as bad as before. I've also heard many horror stories of heads being ruined by them. And I hope you didn't use Q-tips on the video heads, that will destroy them if they catch a strand of cotton. Q-tips are fine for the audio and erase heads. I only use copy paper on the video heads. It's the safest.
