Remote control problems
• Make sure the remote control is set to the correct device
mode (- page 20).
• Remove all obstructions between the remote control and the
TV.
• The remote control batteries may be dead. Replace the
batteries (- page 19).
• Your TV remote control may not operate certain features on
your external device. Refer to the owner’s manual for your
other device to determine its available features. If your TV
remote control does not operate a specific feature on another
device, use the remote control that came with the device

Defaults procedure (- page 33).

configuration (- page 28). If you are still unable to tune

memory (- page 29). If you are still unable to tune digital
channels, use the Reset Factory Defaults procedure
