Setup menu - Geomagnetic Correction
Magnetic interference may come from such things as unshielded motors, moving the TV while it is switched ON, turning off a vacuum cleaner too close to the TV, lightning strikes nearby or many other things. If geomagnetic changes cause colour patches on the screen switch your Television OFF for 30 minutes and then switch it back ON.
Slight tilting of the picture may be noticeable or coloured patches may sometimes appear at the corners of the screen (colour purity).
The Geomagnetic Correction feature can be used to eliminate some interference problems.
Adjustment for geomagnetic should be performed every time the location of the TV is changed.
In some cases colour patches will not be completely eliminated even after adjustment, particularly in ferroconcrete buildings and other structures susceptible to geomagnetic effects. In these cases the TV location will have to be changed.
