How to reset the TV to factory
settings
• 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 22). This setting will
remain in effect until you change the channel or input or manually change the
Wide Mode again.
• You have selected :t text option and no text is available (see page 48). To turn oft"
this feature, set the CC Display option to Off. If you were trying to select
closed captioning, select CC1 instead of Text1-4.
• 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 (or contact your
program provider).
• Programs in 4:3 aspect ratio will have bands on left and right sides of the
screen.
• Programs broadcasted 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, H Stretch 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.
• 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 clots, pixelations) to appear
on your screen. These signal compressions are more visible and are dependent
on the clarity and resolution of the TV.
• 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 t_om obstacles.
• Fluorescent lamps can interfere with your remote control operation; try turning
off the fluorescent lamps.
• 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 47).
• The accessible file or folder limit in a directory is 1,000 for USB and 30,000 for
a DLNA Certified media server. This limit includes non-JPEG, MP3 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.
• Set Display Size to Expanded (see page 32).
• Whether or not photo images can or cannot be displayed in full-screen depends
on the resolution or aspect ratio of the file.
• Depending on the image dimension, file size, and number of files in a folder,
some photo images or fokters take time to display.
• Select the Password settings on the Parental Lock settings, then enter the
following master password: 4357. This password clears your previous password
