Yet another Cinematronics monitor problem solved
I recently picked up an Armor Attack, and after cleaning it up I finally got a chance to play it. It has a revision G monitor chassis, and an Amprex tube with some center phosphor loss.
What I noticed was that the high intensity vectors were very blurry and looked like double vision. I turned the brightness down and the blur/double image went away, but so did all the low intensity vectors.
I've only just started doing research on the monitor including the excellent Cinematronics vector monitor FAQ. It seems to me that the problem is either a failing HV unit, a problem in the intensity circuit or the tube needs a rejuve or replace.
I made a video, and although not exactly clear it first shows the brightness turned down so you can't see the low intensity vectors like the tank treads, damage debris or score text. I then crank up the brightness so the low intensity vectors show up, but the high intensity ones get blurred/doubled. I then turn it down to a point where you can make out the low intensity vectors and the high intensity is starting to blur.
I've got a new HV box on the way, since it seems like a good thing to have either way. I think I'll ask one of the local area collectors if they can try a rejuve to see what that does.
I wanted to post this to see if anyone had experienced this issue and what the fix was, as well as to document it for the future. The video is below, and was recorded in 720p at 60fps.
