@a14g2000cwb.googlegroups.com:

A portable Beta VCR from 1985 works perfectly except there is no color:

1. Pre-recorded color tapes play back in B&W
2. Tapes recorded on this VCR play back in B&W on this VCR
3. Tapes recorded on this VCR play back in B&W on other known good VCRs

Therefore, the VCR can neither record nor playback color signals. What
is the most likely cause?

Is it the 3.58 MHz oscillator, the comb filter, the color killer, or
lack of a color burst? Or, is it just a defective transistor or IC that
contains an internal B&W/color switch?

Thanks


Have you tried cleaning the heads? We had one that went to black and
white and cleaning the heads made it come back to color part way.

I cleaned the heads both manually and with a Scotch cassette cleaner,
but no improvement. Video remains B&W.
