Predator 7000 - Screen image unstable

MickCob

Having purchased my Predator 7000 2 weeks ago, the image on the image on the screen now momentarily drops in size and returns to normal 3 seconds later. This occurs approx every minute.

PS was working fine for the first week

HELP?

Typically that type of artifact is an issue with the power or the cable. Do you have anything else on that circuit that might be firing up on a regular basis, like a refrigerator? Can you swap video cables and reroute them?
