CEC 
Consumer Electronics Control allows  you to control other devices using your HDTV remote control when 
those devices are connected via HDMI. For example, if a CEC-supported Bl u-ray DVD player is 
connected to your HDTV through HDMI-2 and that pl ayer is powered on, your HDTV will automatically 
change to the HDMI-2 input. Similarly, if your HDTV is powered on first and 
your change the input to HDMI-2, your Blu-ray player will automatically 
power on. 
Also, you can control your CEC-suppor ted device using the transport keys 
on your HDTV remote control (e.g. Pl ay, Stop, Prev, etc.). When you press 
one of the buttons on your HDTV, the  action will occur on your device.  
Contact your devices’ user manual or manufacturer to check whether your 
device supports CEC. 
CEC Function 
Turn CEC On or Off. When set to  Off, your HDTV will not send or 
receive any CEC commands. 
Device Discovery 
Register device with TV. Before CEC will work, perform a Device 
Discovery to see if there are any CEC supported devices 
connected to your HDTV.

Chapter 9 Maintenance and Troubleshooting 
 
Cleaning the TV and Remote Control  
1.  Remove the power adapter cable from the TV. 
2.  Use a soft cloth moistened with diluted neutral  cleaner to clean the TV and remote control. VIZIO 
recommends using an HDTV cleaning solution which can be purchased at any major retailer. 
3.  Wring liquid out of the cloth before cleaning to prevent water from penetrating into the housing.  
4.  Wipe the TV and remote control with a dry cloth after cleaning. 
 
Important: 
  Do not use volatile solvent (such as toluene,  rosin and alcohol). Such chemicals may damage the 
housing, screen glass, and remote control, and cause labeling to peel. 
   The screen glass is very fragile. Do not scrape it with any sharp object. 
   Do not press or tap the sc reen to avoid cracking.   
 
 
Troubleshooting Guide 
If the TV fails or the performanc e changes dramatically, check the following troubleshooting guide for 
possible solutions. Remember to check the peripherals  to pinpoint the source of the failure. If the display 
still fails to perform as expected,  contact the VIZIO for assistance by calling 1-877-MYVIZIO (698-4946)

The TV has pixels (dots) that 
are always dark or colored.    Your HDTV is manufactured using an extrem
ely high level of precision technology, 
however, sometimes some pixels of your HDTV may not display. Pixel defects 
within industry specifications are inher ent 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 anot her source, then the volume will change. 
You switch to a different input 
and the screen size changes.   The TV remembers the viewing mode from th
e 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 “W
idescreen”) 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.
