174 Troubleshooting

Sound problems

Check the antenna/cable connections, see “Connecting a digital audio
system” on page 38.
The station may be having broadcast difculties. 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 HDMI™ terminal, make sure that the Rear Shared Audio setting is
properly set, see “Connecting a digital audio system” on page 38.

Remote control problems

Remove all obstructions between the remote control and the TV.
Replace the remote control’s batteries, see “Installing batteries” on page
50.
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 specic feature on another device, use the remote control that
came with the device, see “Learning about the remote control” on page
53.
If the TV still does not act as expected, perform the Reset Factory
Defaults procedure, see “Resetting to Factory Defaults” on page 101.

Channel tuning problems

Ensure that the remote control is set to the correct device mode, see
“Learning about the remote control” on page 53.
The Auto Tuning feature may have erased the channel from memory. To
add the channel to the channel memory, see “Manual Tuning” on page
70.
If you cannot tune digital channels, check the antenna conguration, see
“Initial setup” on page 55. If the problem persists, clear all channels
from the channel list and reprogram channels into memory, see “Storing
channels in memory (optional)” on page 69. For additional information,
see “TV stops responding to controls.” on page 171. If the problem
persists, use the Reset Factory Defaults procedure, see “Resetting to
Factory Defaults” on page 101.
