So I swapped out my k4600 and rebuilt a k7000. Worked great except the white has a yellow tint. Any ideas? Ill post pics when I get my power and internet back. Its on a shinobi game. And when I turn the screen all the way down with the game going. I get a few blue vertical lines on the edge of things that have blue in them. I checked my tube, no shorts or anything. Its a new tube swap.
 
Its almost like its pushing the blue to the edge of the graphics. The sega logo has like one blue edge, but is black. Any ideas?

have a normal K7000 tube/yoke you can test the chassis on to make sure it's not something with the tube or deflection?

Obviously inspect the neckboard, and maybe replace the color processing IC on the main chassis...
 
Sadly i don't have a normal one. Being new to all this, i havent amassed my collection of parts yet. I also noticed that is a tad brighter toward the top, and sometimes down the right side
 
I'd almost say it's a game pcb problem. Have you had that Shinobi up and running on another monitor? That black Sega logo is very strange, usually if the monitor has an issue it won't put a line at the edge of where the color is supposed to be... and looking at your background, all of it looks decent, except it has too much blue (likely because you turned it up trying to get the blue into the white).

So it's almost like only certain graphics (and the red/green/blue scale) aren't displaying properly, which would be the game pcb, not the monitor.

That makes sense. Yeah, Everything looks great, except some of the things that are supposed to contain blue. And the white in the picture is from the glass reflecting light form the light in the room. It isnt nearly as white in person. Id say they look almost spot on. Guess its time to fiddle with things again
