Troubleshooting
Sound problems
Check the antenna/cable connections, see “Connecting a digital audio
system” on page 36 .
The station may be having broadcast difficulties. Try another channel.
The sound may be muted. Press the VOL (+ -) buttons or MUTE button.
If you connect a computer using either the PC IN terminal or an HDMI ™
terminal, make sure that the Rear Shared Audio setting is properly set, see
“Connecting a digital audio system” on page 36 .
Remote control problems
Remove all obstructions between the remote control and the TV.
Replace the remote control’s batteries, see
“Installing batteries” on page
48 .
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
51 .
If the TV still does not act as expected, perform the Reset Factory
Defaults procedure, see “Resetting to Factory Defaults” on page 103 .
Channel tuning problems
Ensure that the remote control is set to the correct device mode, see
“Learning about the remote control” on page 51 .
The Auto Tuning feature may have erased the channel from memory. To
add the channel to the channel memory, see “Manual Tuning” on page
68 .
The Lock feature may have blocked the channel. To unblock the channel,
see “Unlocking programs” on page 91 .
If you cannot tune digital channels, check the antenna configuration, see
“Initial setup” on page 53 . If the problem persists, clear all channels
from the channel list and reprogram channels into memory, see “Storing
channels in memory (optional)” on page 67 . 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 103 .
