I have run into an audio problem on play-back on this VCR, and the other VCR I use. After recording something on the JVC above, on play-back the sound is noticably lower than before this problem, and is only adjustable to a limited level. The sound being not quite satisfactory, and not ideal at all This has come up since 3-4 weeks ago, and was not a problem before. Are the audio heads and/or plugs starting to fade? Is something set wrong on the VCR or VCR menu? I have tried adjusting things and nothing has changed.

The picture is fine, it's the audio on play-back from recording that is a problem. There isn't a problem with the other VCR I use, which is part of a DVD/VCR player/recorder. Things record and play-back fine on there, when I use the latter VCR to record.

Not sure how old the JVCR HRS3800U, but it says copyright 2000 on the users manual. I'd guess some years now, if not 7.

If I replace the JVC HR S3800U, with a different VCR, will that fix things?

I use a sony surround sound system as well. But that hasn't been a problem before, and shouldn't matter.
