Sharp LC-20SH7U LC-20SH7U Operation Manual - Page 31

ENGLISH 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. • 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. The TV sometimes makes a cracking sound. • This is not a malfunction. This happens when the cabinet slightly expands and contracts according to change in temperature. This does not affect the TV's performance. Problems with Closed Caption Feature Misspelled captions are displayed. Captions are not entirely displayed, or captions are delayed behind the dialogue. Captions are displayed as a white box. No caption is displayed in the closed caption-supported program. No caption is displayed when playing the videotape containing captions. Black box is displayed in the TV screen. • Closed captioning production companies may broadcast programs 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 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. • 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. • The videotape may be illegally copied, or the caption signal might not have been read during copying. • "Text" mode is selected for caption. Select "CAPTION1", "CAPTION2" 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.
