Chapter 9: Troubleshooting

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 46).

TV stops responding to controls

•• If the TV stops responding to the controls on the remote control or TV control panel and you cannot turn off the TV, please unplug the power cord few seconds then re-plug to try again.

Other problems

•• If your TV’s problem is not addressed in this Troubleshooting section or the recommended solution has not worked, use the Restore Factory Defaults procedure (page 37).

TV will not turn on

•• Make sure the power cord is plugged in, and then

press .

•• The remote control batteries may be dead. Replace the batteries or try the control panel buttons.

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 38). 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, see 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 46).

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 63).

Video Input Selection problems

•• If the Input Selection 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 Input Selection window.

Cannot view external signals or channel 3 or 4

•• If you cannot view signals from external devices connected to VIDEO, ColorStream® HD, HDMI 1, HDMI 2, HDMI 3, HDMI 4, PC or from channels 3 or 4, make sure the Input Lock is set to Off (page 52).

Poor color or no color

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

•• Adjust the Tint and/or Color (page 46).

Poor composite 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.

Scrolling text problem

•• When slow motion video is present the unit will treat any scrolling text as Film and may cause a slight jitter of the scrolling text. Turning Off the Film Stabilization feature will correct this issue. (page 63)
