General troubleshooting

Before calling a service technician, please check this chapter for a possible cause of the problem and some solutions you can try.

Black box on-screen

•The closed caption feature is set to one of the Text modes (T1, T2, T3, or T4). Set the closed caption feature to Off (page 35,36).

Other problems

•If your TV’s problem is not addressed in this Troubleshooting section or the recommended solution has not worked, please unplug the AC power cord at least 5 second then plug power cord again to restart the TV.

Picture problems

General picture problems

•Check the antenna/cable connections (Chapter 2).

• Press on the remote control or TV and select a valid video input source (page 32). If no device is connected to a particular input on the TV, no picture will display when you select that particular input source. For device connection details (Chapter 2).

•Antenna reception may be poor. Use a highly directional outdoor antenna (if applicable).

•The station may have broadcast difficulties. Try another channel.

•Adjust the picture qualities (page 35).

• If you are using a VCR, make sure

on the remote

control is set correctly (page 22).

 

•Do not connect both a standard video cable and an S-video cable to the VIDEO 1 input at the same time.

Noisy picture

•If you are watching an analog channel (off-air broadcast or Cable TV), you can set the CableClear® feature to reduce visible interference in the TV picture

(page 45).

Video Input Selection problems

•If the Source List window does not appear when you

press on the remote control or TV, press a second time, which will change to the next video input source and display the Source List window.

Poor color or no color

•The station may have broadcast difficulties. Try another channel.

•Adjust the Tint and/or Color (page 35).

Poor composite or S-video picture

•If the TV is connected to an external A/V device (e.g., DVD player, video game system, set-top box, etc.) try using a ColorStream or HDMI video connection instead.

Picture and sound are out of sync

•As with all products that contain a digital display, in rare instances, when viewing certain content (e.g.. television broadcasts, video games, DVDs), you may notice that the sound and picture are slightly out of sync. This phenomenon can be caused by various factors including, without limitation, video processing within the TV, video processing in an attached gaming system, and video processing or different compression rates used by broadcasters in their programming. You may want to try one or more of the following suggestions, which may help to reduce the effect of this phenomenon:

–If the TV is connected to an A/V receiver that has a programmable audio delay feature, use this feature to help synchronize the sound to the picture.

–If you notice this phenomenon only on certain TV channels, please contact your local broadcast, cable, or satellite provider to inform them of this issue.

Sound problems

•Check the antenna/cable connections (Chapter 2).

•The station may have broadcast difficulties. Try another channel.

•The sound may be muted. Press VOL+ and VOL-.

•If you hear no sound, try setting the MTS feature to Stereo mode (page 36,37).

•If you are not receiving a second audio program from a known SAP source, make sure the MTS feature is set to SAP mode (page 36,37).

•If you hear audio that seems “incorrect” for the program you are watching (such as music or a foreign language), the SAP mode may be on. Set the MTS feature to Stereo mode (page 36,37).

Remote control problems

•Make sure the remote control is set to the correct device mode (page 21).

•Remove all obstructions between the remote control and the TV.

•The remote control batteries may be dead. Replace the batteries (page 20).

•Your TV remote control may not operate certain features on your external device. Refer to the owner’s manual for your other device to determine its available features. If your TV remote control does not operate a specific feature on another device, use the remote control that came with the device (pages 22–26).

Channel tuning problems

•Make sure the remote control is set to the correct device mode (page 21).

•The channel may be setting to "Not Viewable" by the

Manual Ch Set feature. Please set "Viewable" to unblock the channel (page 31).

•If you are unable to tune digital channels, check the antenna configuration (page 29). If you are still unable to tune digital channels, clear all channels from the channel list (page 31) and reprogram channels into the channel memory (page 30).
