JVC HR-S3911U SVHS Picture cuts out

[CoogarXR]

Anybody have any experience with a JVC HR-S3911U? It plays for about 10 seconds, then the picture fuzzes out, then it comes back. Routinely, every 10 seconds or so. It's like the tracking is screwing up.

I took the lid off and watched, nothing interesting happens to the tape when the "fuzz" occurs on the monitor. Tried different tapes, same result.

Saw one on ebay for parts that is doing the same thing, so I figured it might be a common problem.

Any of you old pros ever run into this issue or this machine (or hopefully both)?
