I'm beginning to believe this problem is on the game board itself since I've swapped in different deflection boards and HV boards with no change.

BTW - the jitter is more severe at the bottom of the screen which is where I'm pointing the camera but it can be seen in the entire picture. The other not so severe areas seem to be pulsating or jumping slightly. I've read lots of posts with similar issues but haven't read any definitive resolutions. What do you think I should check?
