Using a Wall-Mount Bracket
Your TV can be mounted on a wall using a Wall-Mount Bracket (not supplied) out of the 
box as packaged. Some larger size TV may require removing the Table-Top Stand; refer 
to the instructions provided with the TV.
Prepare the TV for the Wall-Mount Bracket before making cable connections.
For product protection and safety reasons, Sony strongly recommends that you 
use the Wall-Mount Bracket designed for your TV and the installation should be 
performed by a Sony dealer or licensed contractor.
 Follow the instruction guide provided with the Wall-Mount Bracket for your model. 
Sufficient expertise is required in installing this TV, especially to determine the strength 
of the wall for withstanding the TV’s weight.
 Be sure to use the screws supplied with the Wall-Mount Bracket when attaching the 
mounting hooks to the TV set.
The supplied screws are designed as indicated by illustration when measured from 
the attaching surface of the mounting hook.
The diameter and length of the screws differ depending on the Wall-mount bracket 
model. Use of screws other than those supplied may result in internal damage to the 
TV set or cause it to fall, etc.
 Be sure to store the unused screws and Table-Top Stand in a safe place until you are 
ready to attach the Table-Top Stand. Keep the screws away from small children.
 Read the supplied Safety Booklet for additional safety information.

General
TV screen feels warm  Due to the thin profile of this television, the heat generated by the 
LCD panel backlight and supporting electronics will be more 
noticeable. This is normal operation and not a cause for concern.
Wide Mode changes 
automatically The current Wide Mode setting is automatically replaced with the 
4:3 Default setting when you change the channel or video input, 
if 4:3 Default in the Screen settings is set to other than Off. If you 
want to lock in Wide Mode selected with WIDE on the remote 
control, set 4:3 Default to Off in the Screen settings (see page 
39). 
 Check the Auto Wide option in the Screen settings (see page 
39).
Suddenly the picture 
gets smaller The picture gets smaller during the commercials due to the 
method in which the provider broadcasts their content. When HD 
content channels switch to SD content (commercials), the picture 
may be small with a black border.
Auto Wide will not expand the picture during these content 
changes since the content information is regulated by the 
channel signal provider. You can manually change the Wide 
Mode if you prefer (see page 29). This setting will remain in 
effect until you change the channel or input or manually change 
the Wide Mode again.
“Black box” on screen  You have selected a text option and no text is available (see 
page 45). To turn off this feature, set the CC Display option to 
Off. If you were trying to select closed captioning, select CC1 
instead of Text1-4.
Black bands appear at 
the edges of the screen Some wide screen programs are filmed in aspect ratios that are 
greater than 16:9 (this is especially common with theatrical 
releases). Your TV will show these programs with black bands at 
the top and bottom of the screen. For more details, check the 
documentation that came with your DVD/Blu-ray (or contact your 
program provider).
 Programs in 4:3 aspect ratio will have bands on left and right 
sides of the screen.
 Programs broadcast in HD formats (720p and 1080i) with 4:3 
content will commonly have black bands on the left and right 
sides of the screen which are added by the broadcaster (see 
image on left).
Auto Wide will not expand the picture when the black bands on 
the sides of the screen are added by the broadcaster. You can 
manually change the Wide Mode to Wide Zoom, or Zoom to fill 
the screen, which will remain in affect until you change the 
channel or input or manually change the Wide Mode again.
