without seeing a picture I can guess that you may have a shorted green crt or the drive going to it has changed and you may need to turn down the g2 control for the green. If the tube is shorted or bad see what type of warrantee you have on the crts as some sets have two to 5 years. Good Luck

The service manual on page 8 shows how to adjust the Red/Blue/Green screen voltages. To get to the adjustment board, take the front speaker grill off (two screws at the bottom left and right) and set it aside. No need to disconnect any wires. Then remove the plywood board with 4 screws that exposes the screen/focus adjustments. The top 3 adjustments are for focus, and you need not mess with these. The bottom 3 adjustments are for Red/Blue/Green screen voltage rough adjustments. My screen showed red lines, so I had to turn the bottom right adjustment with a philips head screwdriver just slightly until the red gun retrace lines where no longer visible.

OMG! My TV has been sitting in a closet for the last three years because I couldn't afford to have it fixed. I have googled now and then trying to find a cure for its green affliction but never found the right advice until tonight. I can't thank J19666566666 enough!! I just followed the instructions and presto! Working TV again! And just in time for the Oscars (which is like the Super Bowl for me).
The editor in me tweaked the instructions a little...
Its is real easy to fix. There are 2 screws holding the front speaker cover on near the bottom corners (there are plastic plugs covering the screws that need to come out first). Unscrew and remove the speaker cover (pull it out from the bottom a little then sort of down and out to get it loose but be careful because there are wires attached). Next remove the 4 screws holding the particle board panel in place. There will be a cluster of 6 adjustment nobs with a drop of white paint on each one (2 rows of 3 - do not touch the top row). The green is controlled by the bottom middle screw, Using a screwdriver turn it counter clockwise (to the left) ever so slightly (1-3mm) and there you have your TV back. Use the bottom right screw to adjust the red and bottom left screw for blue.
Thanks again so much!
