Try this...
• Make sure that the power cord is correctly connected to both
your TV power connector and power outlet. See
power on page 30. You should see an LED in the front of your
TV panel when a button on the remote is pressed. If you see no
LED activity, try in another outlet or check your fuse box.
• Unplug the power cord, wait 60 seconds, then plug the cord
back in and turn on your TV.
• Other devices (for example, a surround sound receiver,
external speakers, fans, or hair dryers) may be interfering with
your TV. Try turning off one device at a time to determine
which device is causing interference. After you have
determined which device is causing interference, move it
further from your TV to eliminate the interference.
• Adjust the antenna location and rescan. See
broadcast TV channels again
Go to Settings>Input.
• Reception can vary by channel depending on the broadcast
power level of a given station. Contact your cable or satellite
TV provider.
• Make sure that the antenna or cable/satellite TV is connected
securely to your TV.
• Try replacing the cable between the antenna/cable or
cable/satellite box and your TV.
• Make sure that Antenna TV is set up. See
TV on page 41.
• Make sure that the channels are not blocked. See
unrated programs on page 61.
• Make sure that the channels are not hidden. The channel may
have been deleted from the channel list. You can add the
channel back to the channel list. See
lineup on page 57.
• Make sure that you have selected the correct input tile for the
device or service you are trying to use. See
on page 46.
• If you are using a cable or satellite box, use the remote that
came with that box to change channels.
• You will need to factory reset your TV, as the PIN cannot be
recovered or reset any other way. See
on page 67.
Go to Settings>System>Factory reset.
• If the icon or a menu option is grayed, you cannot adjust
settings for the current video input mode.
• When your TV is in use, the temperature rises naturally and
may cause the cabinet to expand or contract which can cause
a creaking noise. This is not a malfunction.
• Unplug the power cord, wait a few seconds, then plug the cord
back in and turn on your TV.
• Make sure that the sleep timer is not turned on. See the Sleep
Timer option in Options menu settings
