I recently bought a Police Trainer arcade machine & I located the pots for adjustment & I cannot get the H sync or the V sync to fully adjust & hold stable. I can get the screen very close & the picture is great, but now matter how hard I try, the screen still rolls horizontally & vertically just a little bit. I also would assume that that the pots shouldn't be so darn touchy. Is this a cap or diode issue? Can anyone help me out here please? Thank you.

Did you check dip switch 7(Sync Polarity)?

Hi, I'm having a similar issue with my vs. Super Mario Bros. machine. It starts at a random position vertically and starts to roll a little from there. Really touchy vhold and even if that worked it starts off misaligned. I'd appreciate any help. Thanks!
