Outdoor Antenna Grounding
If an outside antenna or cable system is connected 
to the TV, be sure the antenna or cable system is 
grounded so as to provide some protection against 
voltage surges and built-up static charges.
Replacement Parts
When replacement parts are required, be sure the 
service technician has used replacement parts speci-
fied by the manufacturer or have the same character-
istics as the original part.  Unauthorized substitutions 
may result in fire, electric shock or other hazards.

Special Features of Your TV
Your new high-definition widescreen television has 
many special features that make it the perfect center of 
your home entertainment system, including:
1080p High-Definition LCD Display System
Your Mitsubishi LED LCD HDTV  uses a full 1920 x 1080 
LCD panel to create the picture you see on the screen.  All 
images are displayed at 1080p.  The TV uses new Plush 
10 8 0 p® 5G digital video processing to convert lower-reso-
lution signals to 1080p for display.
True120Hz and True240Hz
True120Hz (154 and 164 series) and True240Hz (265 series) 
make fast-moving images appear smoother and more fluid, 
free from motion blur.  It does this by doubling the tradi-
tional progressive scan frame rate and creates new frames 
of video between the traditional frames to create smoother 
moving images.  True120Hz/True240Hz also smooth film 
judder (image vibration) that may be present in film-based 
content such as movies.
16:9 Widescreen Picture Format
Enjoy a full theatrical experience in the comfort of your 
home.  View pictures as film directors intended them. 
Digital TV broadcasts, DVDs and newer video game 
consoles support this widescreen format.
Integrated HDTV Tuner
Your widescreen Mitsubishi HDTV has an internal HDTV 
tuner able to receive both over-the-air HDTV broad-
casts (received via an antenna) and non-scrambled 
digital cable broadcasts, including non-scrambled 
HDTV cable programming.
High-Definition Video Inputs
Component Video Inputs.•	  Also called Y/Pb/Pr 
inputs, these inputs receive standard analog video 
formats of 480i, 480p, 720p, and 1080i high-defini-
tion signals.  This provides a high level of flexibility 
when connecting DVD players/recorders, cable 
boxes, and satellite receivers.
HDMI Inputs.•	  These inputs accept digital 480i, 
480p, 720p, 1080i, and 1080p video signals plus 
bitstream and PCM digital stereo signals.  The 
HDMI™ inputs can also accept a variety of PC 
signals and resolutions. 
Used with an adapter, these inputs also accept 
compatible digital DVI video signals.  HDMI 
inputs provide additional high-performance, 
high-definition connections for maximum flexibility 
in your choice of home theater products. The HDMI 
inputs are HDCP copy-protection compatible.
Easy Connect Auto Input Sensing
Easy Connect™ Auto Input Sensing automatically rec-
ognizes when you plug in a device and prompts you to 
assign a name to it.
Home-Theater Control
HDMI Control
Available on all models.  HDMI devices with Consumer 
Electronics Control (CEC) capabilities may be compatible 
with the TV’s HDMI Control feature.  Compatible devices 
can receive control signals through the HDMI connection, 
allowing the TV’s remote control to operate some func-
tions of these devices.
NetCommand with IR Learning
265 Series.  NetCommand® supports IR (infrared) control 
of products such as VCRs, DVD players, cable boxes, 
and satellite receivers.  NetCommand can “learn” remote 
control signals directly from many devices, allowing you 
to create a customized NetCommand-controlled home-
theater system.
Sound Projector
Sound Projector technology uses the TV’s bank of 
speakers to create a simulated surround sound effect 
by reflecting sound off the room walls.
StreamTV™ Internet
StreamTV brings many popular internet applications to your 
TV.  Among them is the VUDU™ movie service, offering the 
largest on-demand HD movie selection anywhere, featur-
ing full 1080p and 5.1 surround sound.  VUDU allows you 
to enjoy movies with no store visits, no mailing, no late fees 
and no subscriptions.
ENERGY STAR®
This is an ENERGY STAR® qualified TV.  Products that 
earn the ENERGY STAR prevent greenhouse gas emis-
sions by meeting strict energy efficiency guidelines set 
by the U.S. Environmental Protection Agency and the 
U.S. Department of Energy.
This TV uses power within ENERGY STAR guidelines 
except when Picture Mode is set to Brilliant.
