• Make sure that Autoscan in the setup screen has been complet-
ed. It will be required when you setup TV for the first time or when
TV is moved to a location where other channels are broadcast.
• The selected channel does not exist at that time. There are not
always minor-channels being broadcast.
• When Autoscan is interrupted and not completed, some channels will
not be received. Make sure to complete Autoscan in the setup screen.
• Many digital channels have alternate channel numbers. TV changes the
numbers automatically to the ones signifying the broadcasting stations.
These are the numbers used for analog broadcasts.
• Check the antenna or cable connection to the main unit.
• Check the battery life of the remote control.
• Check if there is an obstacle between the sensor and the
remote control.
• Test the signal output. If OK, then possible remote sensor trou-
ble. (Refer to “IR SIGNAL CHECK” on page 35.)
• Closed captioning production companies may broadcast pro-
grams without correcting the misspelling in a live broadcast.
• Captions that are delayed a few seconds behind the actual dialogue
are common for live broadcasts. Most captioning production compa-
nies can display a dialogue to a maximum of 220 words per minute. If
a dialogue exceeds that rate, selective editing is used to insure that
the captions remain up-to-date with the current TV screen dialogue.
• When electric waves are interfered due to buildings, weather
conditions etc., incomplete captions may be displayed.
• Broadcasting station may shorten the program to insert the
advertisement. The closed caption decoder cannot read the
information of the shortened program.
• The videotape may be illegally copied, or the caption signal may
fail to be read while coping.
• “Text” mode is selected for caption. Select “CC1”, “CC2” “CC3”,
“CC4” or “Off”.
