The CRT slot aperature mask (shadow mask) is magnetized. If it does not correct itself after several cycles of turning it off, waiting ten minutes, and turning back on, you will need to have it degaussed (demagnetized). Any decent servicer will have the required tool (a coil of wire that looks like a small steering wheel). You used to be able to buy one of these, but they probably are not available any more. I made mine in 1965 from the wire out from a 1940's TV focus coil and still use it. You could use most anything (like a brushless induction motor or transformer) with an AC magnetic field for this, but it might not be strong enough. I'll just bet this problem will fix itself, however.

20" digital flat stero tv moel CR202EM8

It sounds magnetised. Is there a magnet near that side... like a speaker?

It probably needs degaussed. Many TV shops have a device that does this, at a cost to you. Also, the set degauses itself for about a second when it's first turned on after being off for a while. So it may go away by itself eventually.

Hope that helps...
