on (front red LED light should be on; not blinking)
Press the INPUT button on the remote to select the correct input source.
Ensure all connections are correct and secure.
When using external video source, such as a Cable/Satellite box or
DVD player, check that the device is on and functioning correctly.
Press MENU on the TV's remote control. If the menu is
displayed, then the TV is working; recheck above steps.
Press the INFO button on the remote to confirm the type of signal
being received (p. 17). HD signal should be 720P, 1080i or 1080p.
Select a High Definition channel from your HD source
(Cable, Satellite or fiber optic service). HD channels
sometimes broadcast non-HD content.
Ensure that your HD source (HD box, Blu-ray player, etc.)
is connected to the TV with an HDMI or Component cable
and set to output an HD video signal.
Change the format (aspect ratio) of the picture by pressing
the FORMAT button on the remote control. (p.18)
Check the aspect settings on your external video source,
such as Cable/Satellite box, DVD/Blu-ray Disc player, etc.
Note: Some content, such as film-based movies, are available in
extra-wide format. Top and bottom bars are unavoidable.
When using a cable service (without a box), check that all
connections are secure.
When using a cable or satellite box, change the connection
(wiring) to Composite, Component or HDMI. (p.10)
If you're using an antenna, then check that connections are
secure. Change the position or direction of the antenna and
check the "Signal meter". (p.43)
Check if electrical products such as kitchen appliances,
fluorescent lights or light dimmers are nearby. They may
interfere with the TV's picture.
Try viewing a picture from another device, such as a DVD player
or a game console, to narrow down the source of the problem.
Change settings of Closed Caption (CC). (p. 17, 47)
The TV has gone into shutdown mode to protect itself. Try unplugging
it for a few minutes and connecting it again. If there was a temporary
power surge on the AC line it may now be OK. If the blinking returns,
call 1-877-95VIERA (U.S.A.) or 1-866-330-0014 (Canada).
The LCD panel is made up of a few million pixels and is
produced with advanced technology through an intricate
process. Sometimes a few pixels may be bright or dark.
These pixels do not indicate a defective panel and will have
no impact on the performance of the TV.
