You haven't put something magnetic next to it have you? Eg Speakers, kids toy, portable radio etc.

Assuming its a CRT television then it sounds like a fault with the degaussing circuit. This demagnetises the shadow mask when you switch on. Alternatively it could be caused by having speakers nearby.

many thanks for your replies- yes it is a CRT. Not that Im aware of has a magnet been put near and I dont have any speakers near by.
How do I rectify the problem?
