Your set needs to have both Convergence ICs replaced they are Both STK392-010 you can get new ICs at the following link and they provide free step by step instructions with pics so you can do the job yourself which takes about 45 minutes. Heres the link.

I'm almost positive the problem is you have fungus in the CRTs. I know this sounds strange, but it's true. Basically there is coolant fluid in the lamps that develops fungus over time and turns yellow. It should be clear. If you take the back off the television, you will see the 3 lenses (red, green, blue) Each of the lens is held on with 3 screws. Remove the adjustable lens and look at each CRT. Shine a flashlight in they should look white. From what I've read, blue develops the problem first, then green. You can replace the fluid. Look up TV coolant replacement online. It's not to difficult, but you cannot get any of the fluid on the circuit boards or it will ruin it. Mine had a lot of fungus in the blue CRT and a little in the green. The picture looks 100% better now. Good Luck.
