So it is this AU board:

This will not cause the symptom you described.

I do not know, I like to see the screen shot to see what kind of images you are getting on the screen.
BTW, you already try resting the cables and tighten all the boards' mounting screws?

I meant to say re-seating the connectors/cables.

Hey budm,

I did try reseating all cables and screws and I'm still getting same problem. I got pictures of the thin lines or distorted picture. This issue changes in less than a sec. I was able to get a pic with the distortion and another one looking normal.

See if heating, flexing or chilling with freeze spray (dust-off in a can held upside down) affects the symptom. If it does, try to isolate to a specific board and component.
