If you didn't change the system, it changed by itself. That is known as becoming broken. It could be as simple as a loose cable.


Unplug and replug all of your HDMI cables for a quick start.


Your description of your system is not clear to me.


Does the receiver switch the video inputs or does the TV?


Or, is the receiver hooked up to a digital audio output on the TV? Both options can work. One might be more reliable.
