I have a Bang & Olufsen CRT which shifts any RGB signal to the left, cutting off the left side of the screen. No service menu adjustment seems to rectify it. Seems to be a common problem with these sets. With this jamma image position passthrough, this problem is completly rectified.
I have a B&O MX4200, which also shifts the image to the left. I can center the image using the service menu, but a part of the image gets cut off on the left side. It looks worst on my Saturn for some reason, and my other consoles are more or less fine. How did you manage to hook up the position correction board to the TV set? I would like to hook up several consoles to a SCART switch, and then somehow adjust the output from the switch with this board.
I also have an MX 1500 with the same issue, so it would be awesome to have a solution that could fix this issue on all consumer CRTs.
I am a bit of a newbie, sorry if there is a really obvious answer.
