No sound, no video
Use an HDMI-authorized cable. Use a Sony High Speed HDMI cable with Cable Type
Logo.
When you switch sound from a TV to an AV amplifier, or when you put the headphones
on when sound is being output from a TV, the TV screen becomes blank and sound is
muted for a moment. This is not a malfunction.
Make sure that the processor is turned on.
If the processor is turned off, the HDMI Pass Through function does not work. Therefore,
the video and audio signals from the connected device is not input to the TV. Turn on the
processor, or set it to standby mode.
Check the connection. (Connection example 1

If the HDMI Pass Through function does not work properly when the processor is in
standby mode, set [HDMI Pass Through:] to [On] on the menu.
No TV sound can be heard on the system.
