Is it random colour-changes you're experiencing, or is there a pattern to the colour changes? If it's blue faces and green hair, there's a possibility that the red-signal on the telly is b0rked. But if it's the red that's b0rked, you've now got a telly that's halfway between colour and black-and-white (a bi-colour telly). If seeing everything in green and blue is too upsetting for you, just turn down the colour-control and you now have a black-and-white telly in cyan.

Are the colour changes uniform no matter what the input source is (TV, DVD, etc)? If not, there's a chance one of the cables might be slightly loose. In fact, if you have a spare HDMI/DVI/SCART (or whatever) cable, try using that instead of the current one and see if it fixes anything.

As for the concentric circles, the only theory I have is that your telly's possessed.
