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 
53). 
 Check the Auto Wide option in the Screen settings (see page 
53).
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 33). 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 61). 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 effect until you change the 
channel or input or manually change the Wide Mode again.

Other Information
Certain programs on 
DVD or other digital 
sources display a loss of 
detail, especially during 
fast-motion or dark 
scenes This is due to the digital compression of the source content used 
by certain digital broadcasts and DVDs which may cause your 
TV’s screen to display less detail than usual, or cause artifacts 
(small blocks or dots, pixelations) to appear on your screen. 
These signal compressions are more visible and are dependent 
on the clarity and resolution of the TV.
Remote control does not 
operate To determine if the problem is with the remote control or not, 
press a button on the TV.
 Check the polarity of the batteries or replace the batteries.
 Point the remote control at the remote control sensor located at 
the front of the TV.
 Keep the remote control sensor area clear from obstacles.
 Fluorescent lamps can interfere with your remote control 
operation; try turning off the fluorescent lamps.
Some digital cable 
channels are not being 
displayed Certain cable companies have limitations on the broadcast of 
digital cable channels. Check with your cable company for more 
information.
 The digital cable channel may be set to Hidden in the Show/
Hide Channels setting (see page 55).
Some photo, music, or 
video files are not 
displaying from my USB 
equipment The accessible file or folder limit in a directory is 1,000 for USB 
connected equipment. This limit includes non-supported files or 
just folders. Files or folders are populated based on their time 
stamps. Photo, music files or folders exceeding the limit will not 
be displayed.
Photo images appear 
small in the screen Set display size to expanded.
 Whether photo images can be displayed in full screen or not 
depends on the resolution or aspect ratio of the file.
Photo images or folders 
take time to display Depending on the image dimension, file size, and number of files 
in a folder, some photo images or folders take time to display.
 The first time a camera is connected to the TV via USB cable, it 
may take up to a couple of minutes for the photos to display.
Lost password  Select the Password settings on the Parental Lock settings, 
then enter the following master password: 4357. This password 
clears your previous password and allows you to enter a new 
password (see page 56).
How to reset the TV to 
factory settings Turn on the TV. While holding down V on the remote control, 
press 1 on the TV. (The TV will turn itself off, then back on 
again.) Release V.

Sometimes video 
streaming quality is poor 
when using the wireless 
LAN The wireless network connection quality varies depending on the 
distance or obstacles (e.g. wall) between the TV/USB Wireless 
LAN Adapter and the wireless router (access point), environment 
interference, and quality of the wireless router (access point). If 
using USB Wireless LAN Adapter, it is suggested to use a 
wireless router (access point) supporting 5GHz operation for 
video streaming and place it closer to the USB Wireless LAN 
Adapter (not applicable for models with built-in wireless LAN 
device).
Wireless LAN connection 
fails or radio reception 
conditions are poor Check the installation location of the TV and wireless router 
(access point). Signal condition may be affected for the following 
reasons.
- Other wireless devices, microwaves, fluorescent lights, etc., 
are placed nearby.
- There are floors or walls between the wireless router (access 
point) and TV.
If the problem persists even after checking the above, try 
making a wired LAN connection.
Poor picture on Internet 
Video Quality depends on the original video provided by the video 
content provider and your connection bandwidth.
Small picture on Internet 
Video Use the color buttons to zoom in and out.
Certain Internet video 
content displays a loss of 
detail, especially during 
fast-motion or dark 
scenes Video quality and picture size depend on broadband speed and 
delivery by content providers.
