General TV Problems 
Solution 
The TV keeps shutting off 
when I try to open the Quick 
Menu 
• 
Press and hold the Jag wheel for two (2) seconds to open the Quick Menu. 
Holding it for too long will shut off the TV. 
You can see a picture but you 
cannot hear sound. 
• 
Press Volume + (Up) on the remote control.  
• 
Press MUTE on the remote control to make sure that MUTE is not ON.  
• 
Check your audio settings. The audio may be set to SAP, or the speakers are set 
to off. 
• 
Check the audio connections of external devices that may be connected to the 
HDTV. 
The TV has pixels (dots) that 
are always dark or colored. 
• 
Your HDTV is manufactured using an extremely high level of precision technology, 
however, sometimes some pixels of your 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 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. 
• 
If you are using an antenna, the signal strength of the channel may be low. Make 
sure your antenna is connected securely to the TV and move the antenna around 
the room or close to a window. 
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 volume 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-1, AV-2, Component, HDMI and TV). 
Tips for High-Definition Users. 
• 
Your HDTV is an ideal platform for viewing High Definition Content.  
• 
Best image quality will be achieved by HDMI. The next best is Component, 
followed by Composite. 
• 
Due to variances in broadcast practices, it is possible some image distortions can 
occur. 
Tips for Letterbox Content 
Users. 
• 
Some Letterboxed (or “Widescreen”) versions of DVD movies are formatted for 
standard 4:3 Televisions. Your HDTV has the ability to expand this content so the 
entire screen is filled at the expense of image accuracy. To use this function, press 
ZOOM on the remote control to cycle among the options.
