Raspberry Pi - TV Signal lost

Raspberry Pi - TV Signal not found.  Video signal lost.  Also, "Switching audio to TV speakers"

During a long software update or software installation, the video signal is lost.  Switching the TV's input, from [hdmi 1 to hdmi 2, etc.,] did not help.

Issue:
I had the Raspberry Pi connected to the home TV, which was patched through a home stereo.  The stereo receiver would get bored and would power-down (energy savings). 

Powering on the stereo receiver restored the Pi's video.
