Just guesses mind you, but on the VR725, perhaps bad capacitor(s) in a video
preamp or video process module, especially if it's a Panasonic built model,

on the VR-721 perhaps an alignment issue (tape guides, NOT the audio/control
head).

I have two different problems with two different RCA SVHS VCRs maybe the
brilliant folks of the newsgroup could help with....

Firstly, I have a VR725HF which just developed a color problem. On SLP
playback, it has very weak color which flickers on and off. It's OK at SP
speed. Tapes from another machine show the same symptoms, while tapes from
this machine look normal on another machine. So the problem would be in
playback, not record.

The second VCR, a VR721HF, has distorted sound when a tape recorded on
another VCR or is played. A tape recorded on this machine has distorted
sound when played on the other VCR. But tapes recorded and played back on
this machine sound fine.

Any ideas?

Thanks.

I've seen this problem resolved with a good head cleaning but if that doesn't
work, you may need a new amplifier chip. Did the color anomalies develop
suddenly or over time? If the former is the case, you're probably in for an
expensive/time consuming repair

Hi...

Yes, the color problem happened rather suddenly. One day it was OK, the next
day a program I taped had the color problem when played back. The color was
OK when I played it on a different machine. I've done a couple of head
cleanings to no avail.

Thanks.

Follow-up: The problem went away when I substituted an upper drum from a
similar machine (the one with the audio problem).
