Symptom Remedy
The entered channel number
changes automatically
• Many digital channels have alternate channel numbers. The unit changes the
numbers automatically to the ones signifying the broadcasting stations. These are
the numbers used for analog broadcasts.
Remote control does not work • Check the antenna or cable connection to the main unit.
• Check the batteries of the remote control.
• Check if there is an obstacle between the infrared sensor window and the remote
control.
• Test the signal output. If OK, then possible infrared sensor trouble.
(Refer to “IR Signal Check” on page 37.)
• Aim the remote control directly at the infrared sensor window on the front of the
unit.
• Reduce the distance to the unit.
• Re-insert the batteries with their polarities (+/– signs) as indicated.
Problems with Closed Caption Feature
Misspelled captions are
displayed.
• Closed captioning production companies may broadcast programs without
correcting the misspelling in a live broadcast.
Captions are not entirely
displayed, or captions are
delayed behind the dialogue.
• Captions that are delayed a few seconds behind the actual dialogue are common
for live broadcasts. Most captioning production companies 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.
Captions are displayed as a
white box.
No caption is displayed in the
closed caption-supported
program.
• Interference from buildings or weather conditions may cause captioning to be
incomplete.
• Broadcasting station may shorten the program to insert advertisement. The closed
caption decoder cannot read the information of the shortened program.
No caption is displayed
when playing the videotape
containing captions.
• The videotape may be illegally copied, or the caption signal might not have been
read during copying.
Black box is displayed in the
TV screen.
• “Text” mode is selected for caption. Select “CC1”, “CC2”, “CC3”, “CC4”or “Off”.
Note:
• The LCD panel is manufactured to provide many years of useful life. Occasionally a few non active pixels may appear as a fixed point of
blue, green or red. This is not to be considered a defect in the LCD screen.
• Some functions are not available in specific modes, but this is not a malfunction. Read the description in this owner’s manual for more
details on correct operations.
