Weird sync issue on big blue.

Had a Naomi inside a big blue at my local arcade for over a year running Marvel 2. Out of nowhere last Saturday we got this half image. So far I tried a different Naomi board, different Capcom io, different monitor chassis remote board. It all showed the same half image, I also messed with the horizontal hold, horizontal size and it would just cause the image to loose hold and look scrambled. I am suspecting it's the k7000 chassis itself, any suggestions are appreciated.

Fixed, it was the dips on the Naomi 2 had become corroded. So even though the dip was set correct the corrosion would not let it register. Hit it with deoxit and worked it back and forth till it registered again.
