Check your resolution...the chassis is able to produce standard rez. and by moving the jumper, can also do medium rez....it's the big white jumper in the middle of the board. What resolution does the game produce?
 
It kinda looks like a video ground issue to me. Although, yeah, it may be multiple problems, a) resolution mismatch b) something wrong in the green driver circuit (may be just an adjustment).
 
That looks like the medium resolution ONLY version. (either U5000 or K7500)
It doesn't have the second set of header pins to switch resolutions like the dual res versions.

Need to verify what resolution Police Trainer runs at.
(I thought it was a standard res game, but could be wrong)

Could try flipping dipswitch #7 on the game pcb. (something sync related)

Did this monitor EVER work in this machine?
 
yes the game worked, it was hit by lightning.i caped the lower board and a few that came in the kit for the neck board.i installed some diodes and a resistor that was thought to be the problem no help.i know i cant get any blue in the pic as there should be.as for the resoltion the guy thta was helping me said the wires look right.BUT what the deal with the ground i did notice there is a ground on the back of the chassie with no wire to it heres a pic where would the wire come from i dont see any wires that sould go there

That could open up a whole nother can of worms.
You almost need to test another game pcb in that cabinet or your board in another cabinet just to rule out its not a game board issue before focusing on the monitor.
 
police trainner is done being helped,but THANKS EVERYONE

well this is the up date the monitor is good but has no blue in it as for colors.the board is just scrabled.so sad to say it not worth fixing.since i can get a whole game almost for what people want for a board,so im making it a 60 in 1.thanks everyone for your help.i would sell the board and maybe the monitor. i found another police trainner so i may keep the monitor for a spare since it been caped and extra parts put into it.
 
the quality of the tubes on these were kind of bad, but I don't think your missing blue is tube-related. the neckboards on these (and the K7400 and K7500) all had a flaw where the color drive transistors would get hot enough to lift the traces on the back of the neckboard. in turn, the solder pads can often times break off the trace too. there goes your colors. :) I suppose in other really rare cases the color adjustment pots can fail too, particularly the white knob variety (wtf is it with the white knobs?) but I doubt that.

if your transistor has enough leg left sticking out the back, what I've done with these and also with WG D9200s (which also have the same heat problem) is you bend the legs at a 90 degree angle, often times try to face it the same direction as the trace, what this will do is eliminate the flexing that can pull the traces up more. then after that you can either bridge traces with wire or you can scrape the outer layer of the trace and flow some solder on it to reconnect to the transistor legs or solder pad if those are still intact.

I should really do a pictorial guide on this sometime, cause it's saved my ass a few times with a few of our games at work lol

the color transistors, facing the back of the neckboard, go in order of Red Green and then Blue (the 3rd one by the edge). get a meter out and check continuity from the 3 transistor legs to the next points in circuit to verify that the traces are good or bad or whatever.
