INFORMATION
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 23.)
• 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.
• The text mode is selected for caption. Select “C1”, “C2”, “C3”, “C4” or “OFF”.
Note:
• 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.
Cabinet Cleaning
• Wipe the front panel and other exterior surfaces of the unit with a soft
cloth immersed in lukewarm water and wrung dry.
• Never use a solvent or alcohol. Do not spray insecticide liquid near the
unit. Such chemicals may cause damage and discoloration to the exposed
surfaces.
Panel Cleaning
Wipe the panel of the unit with a soft cloth. Before cleaning the panel,
disconnect the power cord.
Servicing
Should your unit become inoperative, do not try to correct the problem
yourself. There are no user serviceable parts inside. Turn o the unit,
unplug the power cord and call our toll free customer support line found on
the cover of this manual to locate an authorized service center.
Degaussing
A degaussing circuit in this unit clears up color errors on the TV screen.
Color errors occur when there is any excess magnetism close to the unit.
This circuit is designed to operate once when the unit is rst plugged
in. If you see minor color errors on the TV screen, unplug the unit for
approximately 30 minutes. When you plug the unit again, the degaussing
circuit will operate to clear errors. Take this step any time the TV screen is
accidentally magnetized or when you move the unit.
IR Signal Check
If the remote control is not working properly, you can use an AM radio or
digital camera (including a cellular phone with built-in camera) to see if it
is sending out an infrared signal.
• With an AM radio:
Tune the AM radio station to a non-broadcasting
frequency. Point the remote control towards it,
push any button and listen. If the sound from the
radio utters, it is receiving the remote control’s
infrared signal.
• With a digital camera
(including built-in cell phone cameras):
Point a digital camera towards the remote control.
Push any button on the remote control and look
through the digital camera. If the infrared light
appears through the camera, the remote control is
working.
