• 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 control 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.

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.

See Appendix E for ordering information and replacement
instructions.
• Adjust picture brightness and contrast to maximum levels.
• Change Lamp Mode from Standard to Bright.

Remarks
Check your VCR's owner's guide for further troubleshooting.
Possible cause: Many VCRs and DVD players provide on-
screen menus at only half-resolution. These lower-resolution
graphics may appear to jitter up and down when the TV con-
verts them to high-definition graphics.
• Turn off video mute for the VCR.
• Begin playing the tape.
• Change the VCR input to the antenna input.
The PerfectColor color balance has been incorrectly set. Reset
the PerfectColor balance.
Upgrade a Category 1 (unmarked) HDMI cable to a Category 2
high-speed HDMI cable.
Normal TV operation. The TV does not correct distortion in the
picture from a computer because the correction process may
cause the edges of the image to be cut off.
Check if the MUTE button is on.
The TV's "Listen to:" setting may be set to SAP.
Check that the Speakers option is set to TV to hear sound from the
TV speakers.
If using an A/V receiver, check that the Speakers option is set to AV
Receiver to hear sound from the A/V receiver speakers.
Perform a System Reset.
Check that DIGITAL AUDIO OUTPUT and/or AVR AUDIO
OUTPUT on TV's back panel is connected to the A/V receiver.
Without this connection, devices connected only to the TV (and
not the A/V receiver) can be heard only from the TV speakers.
Note that this includes the ANT 1/ANT 2 inputs, a device (such
as a camcorder) connected to the front panel, and any other
device sending audio to the TV only.
Check A/V receiver input selection in the Inputs > AV Receiver
menu. If NetCommand is set up incorrectly for the A/V receiver,
see "A/V Receiver Control: Automatic Audio Switching," page
58.
Check A/V receiver input selection in the Inputs > AV Receiver
menu. If NetCommand is set up incorrectly for the A/V receiver,
see "Setup to Control Automatic Video and Audio Switching via
HDMI," page 61.
The TV's Listen to: setting may be set to SAP. See page 40.
