Problem 
Solution 
You can see a picture but you 
cannot hear sound. 
Make sure that the volume is not turned down. 
Make sure that the sound is not muted. 
Make sure that your audio input source cables are connected securely and correctly. 
The TV has pixels that are 
always dark or colored. 
Your LCD HDTV is manufactured using an extremely high level of precision 
technology, however, sometimes some pixels of your LCD HDTV may not display. 
Pixel defects within industry specifications are inherent to this type of product and do 
not constitute a defective product. 
You see “noise” or “trash” on 
the screen. 
When your LCD HDTV’s digital capabilities exceed a digital broadcast signal, the 
signal is up-converted (increased) to match your TV’s display capabilities. Up-
converting can cause noise or trash. 
You switch to a different input 
and the volume changes. 
The TV remembers the volume level from the last time you adjusted it.  If the sound 
level is higher or lower from another source, then the loudness will change. 
You switch to a different input 
and the screen size changes. 
The TV remembers the viewing mode from the last time you used a particular input 
(AV, Component, HDMI and TV). 
Tips for High-Definition Users. 
The LCD HDTV is an ideal platform for viewing High Definition Content.  
Best Image Quality will be achieved by the HDMI Input, then YPbPr, then RGB. 
However, due to variances in broadcast practices, it is possible some image 
distortions can occur. 
Tips for Letterbox Content 
Users. 
Letterboxed (or “Widescreen”) versions of DVD movies are most commonly 
formatted for standard 4:3 Televisions.  The LCD HDTV has the capability of 
expanding this content so the entire screen is filled at the expense of image 
accuracy.  Follow the instructions in page 34.
