I have a Pac Man where the last inch of the right side of the screen just sort of slopes downward at an angle. So far it seems to play fine otherwise. I can post pics if needed.
 
I just read this and am thinking it may be my problem. Thoughts?

"Wells-Gardner K4600
C614 33uf 25vdc Keystoned picture. Sides not straight."
 
there is an adjustment pot you probably missed on the brown daughter card. pretty much in the middle of the board(silver square box with red center). I think its a coarse horizonal hold adjustemt.

there is a hole in the metal frame where you pass a plastic tool and adjust the pot with the power on. if you don't have plastic tool, turn it 1/4 turn with the power off and see what it does.

its kind of covered in the manual. page 3 figure 2.

And that's assuming from your 2nd post that you actually have a K4600. But your problem doesn't sound like keystoning, but rather curl. The above post will help, but you may need to cap it...
 
Pretty sure it is a K4600. Found a label in the bottom of the cab that says 19K4616 and it has both of the cards pictured above. In fact, the brown one that I am to adjust was unplugged when I got it. I powered it on and got no video but could play blind. When I started looking at the monitor I saw that the brown card was wedged in a way that it didn't fall out but was completely unplugged. There is a plastic bar that is supposed to hold them in but I am having trouble getting it to "latch". After plugging it back in I got video but the other symptom I described. I am going to post a pic later when I work on it if only for posterity.

Thanks for the information guys!
 
I haven't made any adjustments yet but here is a picture of what is going on.
