It's a Zenith VCS442. Worked fine until the video playback started to look like the heads needed cleaning (fuzzy picture a bit like bad tracking, but audio OK), tried a wet cleaning casette, no help; opened it up and cleaned the rotating drum and 2 stationary heads (erase and audio?) with a foam swab and alcohol, then dry swabbed and waited 5 mins to dry further. Seemed to solve the problem, but the next day the problem reappeared; did same cleaning routine and again it seemed to do the job, but this time less than a half hour later the video was totally blank (though it looks almost normal on CUE and REW).
Seems like if I 'fix' it again it just might bite somebody.
Is this just another way VCRs go defunct or is there something else that can be done? I'm strictly an amateur with, apparently, just enough repair skills to cause damage. I bought it 2nd hand at a thrift store a few months back.
