General 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 side panel buttons.
Picture problems • Check the antenna/cable connections (Chapter 2).
•Press INPUT on the remote control or TV/VIDEO on the TV side panel and select a valid video input
source (page 69). 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 81).
• If you are using a VCR, make sure the TV/VCR button on the remote control is set correctly (page 28).
• If you have two VCRs connected to your TV, do not connect the same VCR to the TV’s output and input
connections at the same time (page 19).
• 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 82).
Video Input Selection • If the Input Selection window does not appear when you press INPUT on the remote control or
problems TV/VIDEO on the TV side panel, press INPUT or TV/VIDEO a second time, which will change to the next
video input source and display the Input Selection window.

or channel 3 or 4 ColorStream,
®
or from channels 3 or 4, make sure the Input Lock is set to Off (page 99).
Black box on screen • Set the Closed Caption feature to Off (page 84).
Poor color or no color •The station may have broadcast difficulties. Try another channel.
• Adjust the Tint and/or Color (page 81).
•When the ColorStream

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

POP problems •The VIDEO OUT terminal will not output the POP picture (pages 19 and 78).
• If you label all of the inputs as “Hide,” the POP feature will be disabled. If you then attempt to access the
POP feature, the message “Not available” will appear on-screen (page 78).
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 89).
