Video Input Selection problems.
If the Input Selection window does not appear when you press 
INPUT on the remote control or TV, try pressing INPUT a second 
time. This will cause a change to the next video input source and 
will display the Input Selection window.
Poor display color or no color.
The station may be having broadcast difficulties. Try another 
channel.
To adjust the Tint and/or Color, see 
Poor composite picture.
If the TV is connected to an external A/V device (such as a 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, this may occur in 
rare instances, when viewing certain content (such as television 
broadcasts, video games, DVDs). The cause may include, 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. 
Try the following solutions:
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 the problem occurs only on certain TV channels, inform 
your local broadcast, cable, or satellite provider.
Digital audio settings may not be correct. Check the 
connections. See 
Turn off and unplug the TV from the AC wall outlet for a few 
seconds, and then plug it back in.
Sound problems
Check the antenna/cable connections. See 
The station may be having broadcast difficulties. Try another 
channel.
The sound may be muted. Press the VOL (+) button.
