Stream TV-VNC Problems
Symptom
1. The VNC PC cannot be connected.
Remarks
• Check if the MUTE key is on.
• The TV's analog Listen to setting may be set to SAP (analog
program from the ANT input) but no SAP is being broadcast.
• Check that the Sound > Audio > TV Speakers option is set to On
to hear sound from the TV speakers. Possibly the TV Speakers
option is Off.
• If using an A/V receiver, check that the Sound > Audio > TV
Speakers option is set to Off to hear sound from the A/V receiver
speakers.
• Press and hold the POWER button on the control panel for 10
seconds to perform System Reset.
• The language selected in the Setup > Antenna Digital Audio
menu is not being broadcast for the current program.
The TV's analog Listen to setting may be set to SAP (analog program
from the ANT input).
• Check that DIGITAL AUDIO OUTPUT and/or AVR AUDIO OUTPUT
on TV's connection panel is connected to the A/V receiver.
Without this connection, devices connected only to the TV (and
not the A/V receiver) can be heard only from the TV speakers.
Note that this includes the ANT input, a device (such as a
camcorder) connected to the TV, and any other device sending
audio to the TV only.
• Make sure the A/V receiver is set to the correct input.
Plug an unused video plug into the Y/VIDEO jack to activate Auto
Input Sensing. Assign the name CD/Audio or MP3 to make the
audio device selectable in the Input Selection menu.
• Connect the TV's audio output to the A/V receiver.
• Change TV Speakers setting to Off.
Remarks
• Check that the VNC PC (server) is turned on.
• Check that only one VNC server application is running on the PC.
If multiple VNC applications are running on the PC simultaneously,
it causes interference of the server.
• Check the firewall setting on the PC. The firewall may need to be
bypassed by adding the VNC server application to the exception
list of Windows ® firewall setting.
