I have a 33" Sharper Image SI-134 Monitor in which the picture is too small by about an inch on both sides and I cannot get the picture to the top completely either due to four of the pot adjustments on the remote board being against the stops when turned counterclockwise.

I just found the schematics and troubleshooting guide thanks to the Sticky from Ken Layton and the monitor links from Ohmerone. I am going to set up a mirror, as asking my girlfriend to help is only a recipe for disaster.
Any suggestions on how to go about making adjustments safely? I understand how to not fry myself, but I know there has to be a step by step guide as to how to center and adjust the picture using the pots in the back and then up front to make fine adjustments. I worked in an arcade during all of high school, but they would not let me touch the monitors for good reason.

The attached picture is the schematics for my monitor, there is a picture of all of the available adjustments on the bottom of the page.
Thanks in advance,

Scott
** While looking up my monitor I noticed there are two versions of the SI-134, an SI-134 and SI-134DS. Unfortunately, the dual scan version does not show how to change the resolution to medium or contain a pic of the chassis. It would be great if my monitor was in fact a dual scan, I have the PCB and respective video cards for Gauntlet Legacy/ Gauntlet Legends, NBA Showtime on NBC/BLITZ games. Plus a Golden Tee 2005 that is supposed to be run in medium. Golden Tee is what was in the cabinet, and it was set for standard resolution, not medium. I was really hoping the operator made a mistake and never bothered to select the correct res, or I really do just have the standard version and not the dual scan. How can I tell the difference?**
