Sound
Symptom
1. There is no sound even when the
volume is turned up.
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.
• Check that all video inputs are plugged in firmly.
• Press and hold the POWER button on the control panel for
ten 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
appear to jitter up and down.
• Turn off video mute for the VCR.
• Begin playing the tape.
• Change the VCR input from Line 1 to the VCR 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 cut off the edges of the image.
• The aspect ratio may be wrong for the image. Press MORE
and then 0 (FORMAT) to change.
Remarks
• Check if the MUTE key is on.
• The TV's "Listen to:" setting may be set to SAP (analog program
from the ANT input) but no SAP is being broadcast.
• Check that the Speakers option is set to TV to hear sound from
the TV speakers. Possibly sound is being sent to one of the audio
outputs for an A/V receiver or headphones.
• 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.
• Press and hold the POWER button on the control panel for 10
seconds to perform System Reset.
