First check the easy stuff... make sure no magnets (speakers are a
common source) near it like Art said.

Also some makes like Panasonic (might've helped if you posted the make
and model) have a feature in the customer menus called "Geomagnetic
correction". If somebody set this adjustment all the way to one end of its
range, it would produce the symptom you described.

Lastly, you may have a failure in the degaussing circuitry of the TV -
Panasonic has had solder connections and / or failures of their thermistors
that would cause failure of the set to properly degauss at turn-on.

Degaussing the set EXTERNALLY with a degaussing coil or rod is only a
temporary fix... The set should be able to do this for you automatically
each time it is turned on cold. I would recommend correcting the problem
rather than "waving the magic wand" over it, since that wil not permanently
cure it anyway.
