Ok, of the 30 possible errors, I probably committed 29 while trying to figure out my monitor (Thank God I didn't commit the 30th- that being getting bit by 45KV...).
Here are some of the things I learned, Pac:
1: Cable- Make sure you're using the correct VGA pinout to the Monitor leads. Do not assume that the color of the wires mean anything.
2: Arcadeos- Using Arcadeos and still getting the horizontal (vertical in sideways monitor) lines? It's likely a sync issue. Ensure that incabinet=1 in arcadeos, and fiddle with the NTSC output settings a few options down. The defaults are 107 and 5, but you need to tweak the values up to slow down the sync. Start by tweaking the H value only, you're describing an H sync problem. I found my Toei monitor worked on 107 or 108 just fine.
3: Monitor tuning - Although you might find it interesting now that the monitor picture is rotated 90 degrees, you'll want to change that if this is a pure mame cabinet. (Arcadeos allows you to change the orientation via software anyways, and it's much simpler). To rotate the image back to its 'proper' configuration where H and V values correspond with their actual directions, you need to rotate the yoke at the back of the monitor 90 degrees. The yoke is the big magnet with the copper coils at the base of the neck of the tube, usually held from moving by some rubber wedges between the monitor and the yoke, and often with a screw type clamp as well. You'll definitely want to discharge the monitor first before screwing with this, but, ultimately, you do need a picture to adjust things properly. There is an excellent document, with lots of pictures, at http://www.geocities.com/Area51/Station/3975/convergence.html
that describes the process of setting up CRT convergence to get the optimum picture. I found it immensely helpful.
MAME: If you had to tweak Arcadeos to get a picture, you'll likely have to tweak MAME to actually see some of the games. Adjust the Horizontal on each (x)x(y)arc_h setting for the different resolutions. My experience thusfar is that, if you adjusted arcadeos by 2 or 3, then changing Mame settings by 2 or 3 usually gets you within striking distance on any given resolution.
I hope that you find this helpful. This info is largely an amalgum of data that I've harvested from the fine minds on this board in the last few weeks.
