Since a lot of us here have PVM's, I decided to finally post this publicly. I'll be adding other service manuals as contributed by other members.

20m2mdu / 14m2mdu
This manual covers 14M2MD* and 20M2MD* models, but it has also come in handy with my 20M4U and a couple other 14 inch models. Courtesy of yours truly.
Most people should just need 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.
