Picture problems

	2).
••	Press	on the remote control or TV and
	select a valid video input source ( page 34).
	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 42).

	an S-video cable to the VIDEO 1 input at the same

time ( page 14).

Noisy picture

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 1, VIDEO 2, ColorStream® HDMI 1, HDMI 2, HDMI 3, PC, or from channels 3 or 4, make sure the Input Lock is set to Off ( page 48).

Poor color or no color

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

•• Adjust the Tint and/or Color ( page 42).

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.
