So after I recapped the monitor it was nice and bright but I cant seem to get from the middle of the screen up to the top of the screen straight. It has a small wave in it no matter what I do. Any thoughts? I have attached a picture

Check brightness and contrast adjustments first. Probably the contrast.

Make sure the monitor's edge connector foil fingers are clean and making a good ground contact.

Also, over on the game power supply board, replace electrolytic capacitor C9. Originally it was a 1 uf @ 50 volts, but because of frequent failures, Arachnid issued a bulletin requesting the capacitor be upgraded to 2.2 uf @ 50 volts. Be sure to note the polarity before removing it. Many of the power supply boards did not have any silkscreened polarity markings on it for this capacitor!
 
Hey Ken, Thanks for the reply. I tried to adjust the two pots you stated but it didn't fix the problem. I do not have a OEM power supply as I swapped it out for a switching PS with +5/+12/+24 votl taps. Any other ideas? Do you service these monitors?
