Have a good tube that was tested and rejuvenated by a fellow KLOVer and my chassis has been reflowed, capped, fly back, and new HOT. When I turn on a game I just get red. If I turn the red all the way down and the red. Cutoff off and crank the blue and green up all the way I get some color but not much everything is RED!!! Any ideas would be appreciated.

When you turn the red drive and cutoff down (each individually).. do you see a definite change on the screen? In other words, are both of them reducing the red, even a little when turned down or does one not seem to do anything? ..if that's the case, maybe check your pots.
 
Unplug your video connector, check the wiring to it and the pins in it, then reconnect. You never know.

I just had a monitor today (4600) do something similar with blue. Tons of blue in the background, washing out the other colors. Saw that I figured it was the tube and rejuved it, to get the same result. Saw that while I had tons of blue throughout the tube, nothing that was supposed to be blue was actually displaying. I unplugged the video input to make sure it was a chassis issue, and the blue went away. Checked over the wiring and didn't see any problems. Reconnected it and everything was back to normal. Have no idea what was up...
 
Thanks for the help guys, especially Buffett with the donor tube and advise. Found a bad transistor X104 that was causing my problems. Replaced it and the picture is beautiful.
 
Having same problem just no green. Moving the pot does nothing and have traced all the wiring. The game is Mr Do and a G07 CBO. X104 checked out fine.
 
I have fixed alot of monitor chassis with the same problem by just reflowing the pots and transistors on the neckboard

Try replacing R517 if you're pretty sure the green circuit is good. Don't forget to check the input transistors on the main chassis, as well as the voltage into and out of the IC for the green signal...
