The game use's Mits WD57734 monitor, the V37 chassis.
A DLP Projection, with a light engine.

The DMD is bad part #4719-001997
You don't have to remove the Light Engine from the monitor
but if poor lighting you should, its real easy remove the screw's
holding the light engine in along the bottom,disconnect the DVI
cable running to the main chassis open any purse locks
holding any wires around the L/E the whole tray slides out.
cable id's JE,Fb,PE2 and CD all lock quick disconnect cables.

Now at the top of the board are 2 or 3 more quick disconnect
cables then remove screws hold the board pull back alittle
and look behind it there's the colorwheel ribbon be careful
it goes a certain way..i'm going to stop here and get a fresh look
at the next steps so i don't leave out any important procedure's
and return later to edit. Stay tuned!

Projection units have been a spot of darkness and confusion in this world for a very long time. You are doing the community a service, keep it up!
 
Rear Projection tvs

Had a call on a few Mits that were in old sega games,
Namco all 40 and 50 inch screens.
Vs50P,VS-4051,vs50609,with convergence issues,weak tubes
fluid leaks,some have fluid catchers other don't and it leaks
on the signal board and the power/HV board
causing intermittent power issues..leaks down the yokes
ofcoarse the tube runs hot with less fluid and can cause
video issues as the video pass thru the fluid when some is missing
Things to look for on mits.
Very hard to clean off by the time someone gets to
it,it has damaged the board to much.
One tech had replaced the whole chassis with another
for another reason then complained about the convergence
around the edges,won't adjust and didn't have the correct remote
to readjust it,so i told him to get the old chassis and i took
off the long board that held the memory for the advance convergence
settings and installed it on the old new chassis and it was good to go.
So keep that in mind when it happen's to you,if your missing the remote.
I can think of a few more tips, but these are old games and most will go to new tvs
so it may not matter much to anyone.
Some of the models needed option code to get in advance settings
Like pressing menu 0157 for VCj adjustment and menu 0159 for advance convergence
for thre Vs differnt codes for ws models there are websites for free downloads
on schematics..for more info.
I'll add more tips and tricks when i find the time.
