The station may be having broadcast difficulties. Try another channel.
The sound may be muted. Press the VOL (+ -) buttons or MUTE button.
If you are connected to a computer using either the PC IN terminal or
an HDMr _ terminal, make sure that the Rear Shared Audio setting is
properly set, see "Connecting a digital audio system" on page 38.
Remotecontrolproblems
Remove all obstructions between the remote control and the TV.
Replace the remote control's batteries, see "Installing batteries" on page

Your TV's 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, see "Learning about the remote control" on page
56.
If the TV still does not act as expected, perform the Reset Factory
Defaults procedure, see "Resetting to Factory Defaults" on page 100.
Channeltuningproblems
Ensure that the remote control is set to the correct device mode, see
"Learning about the remote control" on page 56.
The Auto Tuning feature may have erased the channel from memory. To
add the channel to the channel memory, see "Manual Tuning" on page
75.
The Lock feature may have blocked the channel. To unbtock the channel,
see "Unlocking programs" on page 87.
If you cannot tune digital channels, check the antenna configuration, see
"Initial setup" on page 58. If the problem persists, clear all channels
from the channel list and reprogram channels into memory, see "Storing
channels in memory (optional)" on page 74. For additional information,
see "TV stops responding to controls." on page 173. If the problem
persists, use the Reset Factory Defaults procedure, see "Resetting to
Factory Defaults" on page 100.
