Wide Mode changes automatically
If the 4:3 Default in the Screen settings is set to other options than Off, the current Wide Mode setting is
automatically replaced with the 4:3 default setting when you change the channel or video input. If you want to
select the Wide mode from the Zoom

Check the Wide options in the Screen settings.
Picture size reduces suddenly
The picture size reduces during the commercials. This is because of the way the provider broadcasts the
commercial content. When HD content channels switch to SD contents (commercials), the picture size will reduce
and will be surrounded by a black border.
Black bands appear at the edges of
the screen
Some wide screen programs are filmed in aspect ratios that are greater than 16:9 (particularly for theatrical
releases). When displaying these programs, black bands will appear at the top and bottom of the screen .
Programs in 4:3 aspect ratio will have bands on the left and right sides of the screen.
Some details are lost when displayed
in certain programs on DVD or other
digital sources display, particularly in
scenes with fast motion or a darker
tone
This is because the digital compression of the source content used by certain digital broadcasts and DVDs may
cause your TV screen to display fewer details than usual or artifacts (small blocks or dots, pixilation) on the
screen. These signal compressions are more visible and depend on the clarity and resolution of the television.
Remote control does not operate
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.
Fluorescent lamps can interfere with the operations of your remote control. Turn off fluorescent lamps and try
again.
Remove obstacles within effective range of the remote control sensor.
