Image Issues
5. My picture is not filling the screen. I have black bars around my picture.
 This is due to the aspect ratio. An increasing amount of digital TV and movies are presented in wide
screen (16:9).
 Different sources and TV stations may broadcast different aspect ratios. The aspect ratio may need to be
changed as you change to a different source or TV station.
 To change the appearance of the screen, cycle through these four options by pressing the Zoom button
on the remote:
o Normal: Selects the aspect ratio that matches to source’s aspect ratio (4:3 or 16:9).
o Wide: Displays a full-screen image.
o Zoom: Enlarges the picture. The top and bottom may be cropped.
o Cinema: Stretches the image at the edges while maintaining a clear image in the center of the
screen.
6. I have poor picture quality.
 Make sure your cable connections are connected securely.
 If you are receiving service from a cable or satellite provider, reception can vary by channel depending on
the broadcast power level of a given station. Contact your cable or satellite provider.
 If you are using an antenna, the signal strength of the channel may be low.
o Check the signal strength of the digital channels:
1. Press CH ^ or CH v to select the channel you want and to view the selected channel
strength.
2. Press MENU. The on-screen menu opens.
3. Press ◄ or ► to highlight Channel, then press ▼. The Channel menu opens. The
DTV signal strength is shown at the bottom of the menu.
4. Move the antenna around the room or close to a window. Check the signal strength of
the digital channels again. The optimal location may vary by channel.
5. Press EXIT to close the menu.
o The UHF band (channels 14 and higher) is more directional than VHF (channels 2-13) and
more sensitive to obstacles (such as trees, tall buildings, and mountains) that lie between your
antenna and the broadcast tower. Getting good UHF reception can be more difficult than VHF.
o If you're getting marginal reception of digital signals, both the picture and sound might freeze or
break up to the point that it's not watchable. If you're really on the fringes—either too far from a
tower or with too many obstacles in the way—you'll see a black screen that says "No signal".
o Reception can vary by channel, depending on the location and broadcast power level of a given
station.
o Make sure your antenna is connected securely to the TV.
o Use a basic indoor set-top antenna designed to pick up both VHF and UHF.
OR
Use a set-top antenna that has a built-in signal amplifier.
OR
Use an antenna mounted on your roof or in your attic.

devices.
 The video cable(s) you are using may be bad, try a new set.
 If you are using an antenna, the signal strength of the channel may be low.
