Service menu should be similar to the 20M2MDU. Grab that manual from here: http://www.neo-geo.com/forums/showthread.php?248672-PVM-Service-Manuals-20M2MDU-and-others

see Section 3 - Set Up Adjustments starting on page 19 of the PDF. This explains how to access the service menu, and default settings and setting ranges for most common adjustments.

Ok, thank you very much for the info. Viewing Service Map 1, I see that there are several VSIZE and HSIZE, what would have to adjust?

If the image is off to the right, you may need to adjust H FREQ or VIDEO PHASE, as well as H SIZE

Ok, but there are several HSIZE, to the left of the map shows: "NOR 50 DEF", "NOR 60 DEF", "NOR DEF" ... what does this mean?

the 50 / 60 has to do with PAL / NTSC. Adjustments that do not have 50 or 60 should affect both NTSC and PAL sources.
Most likely you will want to adjust the NOR DEF or NOR 60 DEF unless you are working with a PAL input source.

Ok, I am working with a PAL input source, then I think I'll have to adjust "NOR 50 DEF". Thank you very much for the info.

No problem. When you are happy with the settings press "degauss" twice to save them, then exit the service menu the same way you got in (enter+degauss at the same time if I remember right)
If you do not save before exiting the service menu you will have to make the adjustments again if you turn the monitor off and back on.

I've got to adjust the geometry. But rather than set with "NOR 50 DEF" I had to set "NOR DEF H SIZE" and "NOR 60 DEF H FREQUENCY". I do not understand, because if my signal is PAL, it would have worked with "NOR 50 DEF".
