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.
One or more promotional
logo(s) appears (appear)
on the screen. (Demo
Mode) • Press RETURN on the remote control to suspend Demo Mode.
Then, press HOME, select Settings and proceed with Initial
Setup in the Setup settings. Be sure to select Home on the
viewing environment (Location) step.
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
40).
• Check the Auto Wide option in the Screen settings (see page
40).
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 47). 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.
