Servicing
Should your unit become inoperative, do not try to correct the problem
yourself. There are no user serviceable parts inside. Turn off the unit,
unplug the power cord and call our toll free customer support line found on
the cover of this manual to locate an authorized service center.
Degaussing
A degaussing circuit in this unit clears up color errors on the TV screen.
Color errors occur when there is any excess magnetism close to the unit.
This circuit is designed to operate once when the unit is fi rst plugged
in. If you see minor color errors on the TV screen, unplug the unit for
approximately 30 minutes. When you plug the unit again, the degaussing
circuit will operate to clear errors. Take this step any time the TV screen is
accidentally magnetized or when you move the unit.
If the Laser Optical Pickup Unit is Dirty
If the unit still does not perform properly when it is operated, while refer-
ring to the relevant sections and to "Troubleshooting Guide" in this owner's
manual, the laser optical pickup unit may be dirty. Consult your dealer
or an Authorized Service Center for inspection and cleaning of the laser
