Sony DV32TW77 TV has green glow spots now?

Hello, Just today we noticed two green glowing spots (about 4" in diameter, but not a perfect circle) on the bottom left and right of the screen. The left green glowing spot is about 3" above the bottom and the right one is actually half exposed and touches the bottom. Also there is an intense blue (border line purple) glowing spot about 2" in diameter towards the bottom left too. I speculate it could be the RGB guns but haven't a clue as to how to adjust them. I've read a lot about purity magnets too, but again not too knowledgeable at this point. Does anyone know what may be causing this and/or how to rectify? I have the SAMS manual and can enter "Service Mode" too. Thanks, Roy
