Got a g07 that is exhibiting too much green. Board works great. Started out as just solid green:


Edit: tell me this machine doesn't look possessed here! Love it lol

R/g/b cutoff had little to no change. ...After adjusting red/green drive on neckboard:

I'm not sure my next move, so any help is much appreciated!

EDIT: sorry - missed your text between pics...please ignore...these aren't the droids you are looking for...

A couple suggestions you may have already tried, but here they are anyways:

1. Cap kit
2. Adjust GREEN drive (pot should be on small neck board)
3. Check wiring from PCB
(red & blue might not be connected, or maybe the pins on the monitor chassis
need to be re-flowed)
 
Turn brightness down a bit to get some of the glare to go away.

There is a five pin connector on the main chassis that goes to the neckboard. Unplug it (with power off) then see if it's still too much green. If not, then your issue is on the main chassis.

If so, then shut it off and remove the green drive transistor on the neckboard and see if it's still mega-green. If not, replace that transistor and try again. If so, then your tube may need to be checked with a rejuvenator...
 
that's over-contrast, and should go down as the brightness goes down, unless the issue is a focus problem...
 
Ok, my soldering iron is not with me, so I couldn't mess with the transistors..I was messing around with the neckboard, and pushed on the bottom left of it and the screen turned red, with the blurry graphics still showing.

Barely any green at all. It pops back into it's green state when I relieve the pressure on the neckboard. It's almost like it's loose or something. More adjustments got the color almost correct, though still blurry, graphics kinda streak to the right.

When I adjust the screen on the flyback, it goes to a washed out green, whatever pressure I had on the neckboard.

I had a hard a time getting much blue to show as well, though there is some present. Don't know if any of this may be of importance but figured I'd share.

No pics cuz no camera, and iPhone sux (but you get the jist) :-/
 
Sounds like broken traces on your neckboard? Check for cracks on your neckboard and verify with multimeter.
