10 Troubleshooting

Before calling a service technician, please check the following table for a possible cause of the symptom and some solutions.

Symptom

Solution

TV will not turn on

¥

Make sure the power cord is plugged in, and then press POWER.

 

 

¥

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

 

 

¥

If you have recently replaced the lamp unit, make sure the lamp unit and lamp unit door are installed properly (pages

 

 

 

103Ð105).

 

 

¥

The lamp unit may need to be replaced (pages 103Ð105). Also see ÒLED indicationsÓ on page 99.

 

 

 

 

Picture problems

¥

Check the antenna/cable connections (Chapter 2).

 

 

¥

Press INPUT on the remote control or TV/VIDEO on the TV control panel and select a valid video input source (page

 

 

 

67). If no device is connected to any of the inputs 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 79).

 

 

¥

If you are using a VCR, make sure the TV/VCR button on the remote control is set correctly (page 26).

 

 

¥

If you have two VCRs connected to your TV, do not connect the same VCR to the TVÕs output and input connections

 

 

 

at the same time (page 18).

 

 

¥

Do not connect a standard video cable and an S-video cable to VIDEO-1 or VIDEO-2 on the TV back (or VIDEO-3 on

 

 

 

the TV side) at the same time (Chapter 2).

 

 

 

 

 

Noisy picture

¥

If you are watching a tuned analog channel (off-air broadcast or Cable TV), set the CableClear¨/DNR feature to AUTO

 

 

 

to reduce visible interference in the TV picture (page 80).

 

 

 

 

 

Video Input Selection

¥

If the Input Selection window does not appear when you press INPUT on the remote control or TV/VIDEO on the TV

 

problems

 

control panel, press INPUT or TV/VIDEO a second time, which will change to the next video input source and display

 

 

 

the Input Selection window.

 

 

 

 

 

Cannot view external signals

¥

If you cannot view signals from external devices connected to VIDEO 1, VIDEO 2, VIDEO 3, or ColorStream,¨ or from

 

or channel 3 or 4

 

channels 3 or 4, make sure the Input Lock is set to Off (page 95).

 

 

 

 

 

Black box on screen

¥

Set the Closed Caption feature to Off (page 82).

 

 

 

 

 

Poor color or no color

¥

The station may have broadcast difficulties. Try another channel.

 

 

¥

Adjust the Tint and/or Color (page 79).

 

 

¥

When the ColorStream¨ signal source is active, the VIDEO OUT terminal outputs blank video. To receive video from the

 

 

 

VIDEO OUT signal, a standard video or S-video IN terminal must be used instead of the ColorStream¨ connections.

 

 

 

 

 

POP problems

¥

The VIDEO OUT terminal will not output the POP picture (pages 18 and 76).

 

 

¥

If you label all of the inputs as ÒHide,Ó the POP feature will be disabled. If you then attempt to access the POP feature,

 

 

 

the message ÒNOT AVAILABLEÓ will appear on-screen (page 76).

 

 

 

 

 

Picture brightness changes soon

¥

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

 

after turning on TV

 

will switch to Low Power mode in approximately 1 minute. You will notice a change in screen brightness when this

 

 

 

happens. This is normal and is not a sign of malfunction. (See page 75.)

 

 

 

 

 

Poor composite or

¥

If this TV is connected to an external A/V device (e.g., DVD player, video game system, set-top box, etc.) Always try to

 

S-video picture

 

use the ColorStream video jacks (and corresponding audio jacks) or the HDMI input (if available) for connection to

 

 

 

such external A/V device. This will reduce the amount of video processing to be performed by the television.

 

 

 

 

 

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, DVD), 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/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.

 

 

 

Memory card

¥

Make sure you are using a supported or valid memory card format (page 87).

problems

¥

Make sure you have saved the picture files in the correct file format (page 87).

 

 

 

 

¥

The card may be inserted improperly. Remove the card and reinsert it (page 88).

 

 

¥

The memory card may be empty.

 

 

¥

The memory card may be damaged.
