JVC Color issues

[Simon de Little]

I recently turned on my GY-HM700 and found the picture completely washed out, mainly yellowish-green or pinkish-purple. Have reset everything, played with white balance, looked through manual, message boards etc to no avail.

Any ideas what could be going on here?

Have attached a couple stills showing the issue
