Chapter 8: Troubleshooting

Picture brightness changes soon after turning on TV

•If you set the lamp mode to Low Power, each time you turn on the TV, the lamp will start out in High Bright mode but will switch to Low Power mode after a short period of time. You may notice a change in screen

brightness when this happens. This is normal and is not a sign of malfunction (- page 55).

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 (- Installation Guide).

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

•The sound may be muted. Press z.

•If you hear no sound, try setting the MTS feature to Stereo mode (- page 45).

•Make sure the Speakers function in the Audio Setup menu is set correctly (- page 46).

•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 45).

•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 45).

•When using an external audio amplifier, if you connect the amplifier to the VAR. AUDIO OUT terminals, the

volume of the TV and amplifier must be set above 0 or you will not hear any sound (- Installation Guide).

Remote control problems

•Make sure the remote control is set to the correct device mode (- page 16).

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

•The remote control batteries may be dead. Replace the batteries (- page 11).

•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 (- page 16).

•If the TV still does not act as expected, use the Reset Factory Defaults procedure (- page 31).

Channel tuning problems

•Make sure the remote control is set to the correct device mode (- page 16).

•The channel may have been erased from the channel

memory by the Channel Add/Delete feature. Add the channel to the channel memory (- page 27).

•The channel may be blocked by the Channels Block feature. Unblock the channel (- page 49).

•If you are unable to tune digital channels, check the antenna configuration (- page 25). If you are still

unable to tune digital channels, clear all channels from the channel list (-page 27) and reprogram channels into the channel memory (- page 26). If you are still unable

to tune digital channels, use the Reset Factory Defaults procedure (- page 31). Also see “TV stops responding to controls” and “Other problems” (- page 76).

Closed caption problems

•If the program or video you selected is not closed-

captioned, no captions will display on-screen (- page 43).

•If text is not available, a black rectangle may appear on-

screen. If this happens, turn off the closed caption feature (- page 43).

•A closed caption signal may not display correctly in the following situations: a) when a videotape has been

dubbed; b) when the signal reception is weak; or c) when the signal reception is nonstandard (- page 43).

Rating blocking (V-Chip) problems

•If you forget your PIN code: While the PIN code entering screen is displayed, press Efour times within 5

seconds. The PIN code you previously stored will be cleared (- page 47).

•The V-Chip feature is available for the U.S. V-Chip system only (- page 48).
