I did have a set of speakers and a subwoofer near the TV, they had been there for a few months though so it's strange it would only happen now. I've moved them anyway and unplugged the TV and I'll leave it until the morning.@ Jaym, have you got any speakers (stereo/hometheater) near the tv? I had that a couple of weeks ago an a fairly new sony crt. Have had the speakers near it for ages but for some reason i got the green tint going through it. Moved the speaker and left it for a day and then it was fine again. Supposedly to do with magnetic fields. Also read that you can use a magnet and make circular motions from outside to in to "reset" them. Dont know if it works though. Worth a try to save some money.
If that fails I'll see if I can find some magnets and try your suggestion.
