is this an inverted image or a wiring issue?

Hey Guys please help out.

The game/PCB is fine
The camera is fine

The image or wiring for this monitor looks inverted to me.

before I completely track down all of the wiring I was looking for some quick help as to where to look into.

Monitor: K7000
Cab: Double Dragon

It should look like this.

I do see reds, blues and green on there. Could two of the the colors being swapped do this?

I inverted the colors (negative image) in PSP, here's what it looks like (attached).

Never seen that game, so I don't know what it's suppoed to look like.

BTW, I don't really see any green in the original.

Red & blue look swapped, and I still don't think I see any green.
 
OK I know now that when plug in the green and the blue that it makes a change to the screen. Red isn't making any difference when I plug it in and out (from the barrier strip)

I need to track down the wiring. I don't think it's the neck board IC's
 
I may deal with that K7000 monitor later. I wanted to get this machine working fast.

I swapped in a vert mount 4900 that I had rebuilt/fixed and left on my garage floor for something like this.

I know it's a monitor issue now. I'm wondering if a cap kit may help it. I have to throw the tube on my rejuv also to test it.
