I have a JVC GR-DVM90U camcorder that has a video problem.

The problem is when I record images...

In the record mode the images on the display (and thus also on the tape) are
bad. The images look almost like they have inverted colors ?

Mainly they are "lime green", "blue" and "Fuchsia" (pink). The image is
correct (although hard to discern) but the colors are all wrong...
