• Test the signal output. If OK, then possible infrared sensor trouble. (Refer to “IR Signal Check” on page 24.) • 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” 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 off 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 fi 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 fl 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. ..Maintenance 25 EN INFORMATION WATCHING INTRODUCTION CONNECTION INITIAL OPTIONAL INFORMATION TROUBLESHOOTING ATSC Acronym that stands for Advanced Television Systems Committee and the name of the digital broadcasting standards.
