Video Input Selection problems.
If the Input Selection window does not appear when you press the 
INPUT button on the remote control or the TV control panel, press 
the INPUT button a second time. The TV displays the next video 
input source and the Input Selection screen.
Cannot view external signals or channel 3 or 4.
If you cannot view signals from external devices connected to 
VIDEO 1, VIDEO 2, ColorStream HD1, ColorStream HD2, HDMI 
1, HDMI 2, HDMI 3, HDMI 4, PC, or from channel 3 or 4, ensure 
that the Input Lock is set to Off, see 
Poor display color or no color.
The station may be having broadcast difficulties. Try another

Poor composite 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, this may occur in 
rare instances, when viewing certain content (e.g. 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:
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.
