As always if you decide to do these modifications yourself , you must be happy you know what you are doing and accept that there is a risk of damage to your projector if not correctly modified. This document was written by "Tim in Phoenix" - Many thanks for the information. You can all add your thanks to Tim using the "Thanks" button at the bottom of post 3 in this thread. I consider this modification to have a difficulty rating of 1/10 - Easy basic electronic and soldering skills required. Marquee Anamorphic Mods On newer Marquees, the Vertical Deflection Module is located on the rear heat sink behind the blue CRT (see PIC 1). The mod requires a phillips screwdriver, soldering tools, and three 56k ohms, 1/4w, 5% resistors. Remove the Marquee's top gray metal covers and remove four phillips screws across the top of the rear heat sink, which should permit you to open the rear heat sink on its' hinge; do not allow the yoke wires to be pulled or stressed. Locate R704, R804, and R904 on the vertical board, they are close to the yoke molex pins and should be marked orange, black, orange to denote 30k ohms. Remove these three resistors (see PIC 2), this can usually be done without pulling the board from the heat sink. Take care not to damage the foil traces of the PC board. Form he 56k resistors into U shapes with short leads (see PIC 3), and solder them into the places where the 30k ohm resistors were located (see PIC 4). Reassemble the unit with covers, and power up the unit. Next, go into UTIL, 9 and enter the passcode 0901 for the Service menu, select 3, and match red and blue raster heights to green so as to place the least load on dynamic convergence. Touch up geometry and convergence as needed and the mod is complete.
