ussally when u get coloerd outlined this idicates ether a convergence or a focuse problem.. the green convergence has become shifted. not lineing up with red and blue.. this also could indicate a green crt problem.. my advice is to get a tech to check it out.. it could be a simple adjustment or a whole new green crt

This sounds like a convergence problem which means that your convergence amps have malfunctioned. You can change these out yourself, however you will also have to change out all of the biasing resistors connected to the amplifiers. To do this:
1) Unplug the TV and then get a schematic of the TV I use http://www.servicemanuals.net or http://www.manualsparadise.com
2) On the schematic locate the STK329-xxx series IC packs (usually attached to a large heat sink)
3) determine if the STK329s are 110, 120 or 150.
4) if the STK329-xxx's are 110s replace with 110s (forget that upgrade stuff it is a hit or miss game that I don't believe you want to get into), if they are 120s replace with 120s and so on.
5) Now to replace the STKs: remove the module from the TV and unsolder the old STKs along with the bias resistors, and replace them with the new ones (be sure to apply heat sink paste to the STKs when attaching them to the heatsink)
6) make sure there are no short circuits form your soldering job.
7) Reinstall the module and then turn on the TV.
8) do an auto-convergence test and then things should be back to normal.
Now if you think you can do this have at it, if not I would suggest that you have it done by a qualified TV technician.
I hope this helps,

this CRT TUBE internal Problem, first use CRT Rejuvenation Device. If dont repair you must change CRT TUBES

Thanks for using FixYa. From what you have described it seems that you have to replace the convergence IC and check power resistor for leakage, if values are not exact you have to replace them. The typical cost to get this fixed by a pro is about $300 - and it doesn't mean that he/they will do a job better than you do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do it yourself. Replacing only the IC's MAY solve the problem; however, many people have also had blown resistors requiring replacement. Why would you ask should you replace both of the IC's if only one is shot?! If one is shot the other one is not far away and for that little price of the chips it worth changing them both at the same time. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice. Please do rate the solution if the issue is resolved or else revert for further assistance.

Sounds more or less a color wheel issue, what are the other symptoms?
9 times out of ten the color wheel will do this and that is what it seems to be,
