The image quality is not good.

•For the best image quality, view high-definition programs using digital sources. Connect your devices with HDMI cables.

•If you are using an antenna, the signal strength of the channel may be low. Ensure your antenna is connected securely to the TV and move the antenna around the room or close to a window for the best signal.

The picture is distorted.

•Nearby electrical devices may be interfering with the TV. Separate the TV from electrical appliances, cars, or fluorescent lights.

•Ensure all cables are securely attached.

The display image does not cover the entire screen.

I see “noise” or static on the screen.

•When your TV’s digital capabilities exceed a digital broadcast signal, the signal is up-converted (improved) to match your TV’s display capabilities. This up-converting can sometimes cause irregularities in the image.

•If you are using an antenna, the signal strength of the channel may be low. Ensure your antenna is connected securely to the TV and move the antenna around the room or close to a window for the best signal.

When I change input source, the volume changes.

•The TV remembers the volume level on each input source. If the volume level on the new input source is higher or lower than the level on the source you switch from, the difference may be noticeable.

•Use the Volume Up/Down buttons on the remote to adjust the volume.

When I change input source, the display image changes size.

•The TV remembers the viewing mode on each input source. If the viewing mode on the new input source differs from the one on the input source you switch from, the difference may be noticeable.

•See Changing the Screen Aspect Ratio on page 20.
