centipede my monitor and game work but my image is reversed like a mirror?

ok so i finally got around to start to work more on my centipede, the game powers on, I can see everything, however the image is completely backwards ? do i need to tweak the monitor in some way ? any help is appreciated.

PS the cabinet is set up for JAMMA it does not have the original centipede wiring, I'm using a centipede to jamma adaptor. I tested another random JAMMA game and the same issue. So it's not the PCB. Everything has the "mirror" effect"

on the monitor chasi the vert. hold doesn't do anything, I'm thinking it might be the issue. If so how can I resolve this ? I think that's what rolls / reverses what I need to but it's not doing a thing.
