provider. No other data is available.

Remarks
• When switched on, the TV needs time to boot up, just
as a computer does. Also, the TV's lamp requires a few
moments to heat up to full brightness.
• TV Energy Mode is set to Low Power. Change TV Energy
Mode to Fast Power On in the Setup menu.
• The TV may be locked.
• The clock may not be set.
• TV Energy Mode is set to Low Power. Change to Fast
Power On in Setup menu.
If light on front panel is blinking, wait for at least one minute for
the light to turn off, then press POWER again.
• Momentary power fluctuation caused the TV to turn off to
prevent damage. Wait for the green light to stop flashing
and turn the TV on again.
• If the TV does not stay on, use the System Reset button on
the front panel. If this happens frequently, obtain an AC line
power conditioner/surge protector.
• An unusual digital signal may have been received, triggering a
protection circuit. Wait for the light to stop flashing and turn TV
on.
• The TV has overheated. Clear blocked air vents and ensure
at least four inches of clearance on all sides of the TV.
• Clean the lamp-cartridge air filter. See Appendix C.
Use the System Reset button.
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.
• The lamp is nearing the end of its life. Order a new lamp.
See Appendix C for ordering information and replacement
instructions.
• Adjust picture brightness and contrast to maximum levels.
• Change Lamp Mode 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 infor-
mation being broadcast.
