The courses I took on analog video signals took about a year overall but in short it looks like something has gone out of sync. These older analog video systems are thankfully dying off now.
I was going write "try looking for any tracking adjustment" but that's for tape playback so this means that some video frequency has drifted. Given the cost of repairs today you swap out the camera.

I have a sony handycam TR305E and there are coloured bands/stripes shimmering on the image, here:

It gets particularly bad on dark areas of the screen. This screenshot is taken from the tv out socket of the cam. The tape transport is broken so I can't test a tape recording. I've tested the tv-cable and the tv monitor using another cam and they're both fine so the problem is with this camcorder. What causes this? is it repairable?
