Before calling a service technician, please check the following table for a possible cause of the symptom 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 top panel buttons.
Picture problems	¥ Check the antenna/cable connections (Chapter 2).
	¥ Press INPUT on the remote control or TV/VIDEO on the TV top panel and select a valid video input
	source (page 56). 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 65).
	¥ 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 on the TV back 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 66).
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 top 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, or ColorStream¨, or
or channel 3 or 4	from channels 3 or 4, make sure the Input Lock is set to Off (page 78).
Black box on screen	¥ Set the Closed Caption feature to Off (page 68).
Poor color or no color	¥ The station may have broadcast difficulties. Try another channel.
	¥ Adjust the Tint and/or Color (page 65).
	¥ 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.

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.
