Remarks
Not all signals are high-definition signals. To receive high-defini-
tion programming from your cable or satellite provider, you must
subscribe to the provider's high-definition service. Some over-
the-air broadcasts are in high-definition and can be received with
a high-quality antenna suited to your location.
Press and hold the POWER button on the control panel for 10
seconds to perform System Reset.
• The lamp is nearing the end of its life. Order a new lamp.
• Adjust picture brightness and contrast to maximum levels.
• Change Lamp Energy from Standard to Bright.
The TV's analog closed captioning has been set to "text" mode
in the Captions menu. Turn off because there is no text informa-
tion being broadcast.
Check your VCR's owner's guide for further troubleshooting.
Stop playback. Possible cause: Many VCRs and DVD players
provide on-screen menus at only half-resolution that may

cause the edges of the image to be cut off.
