I have a HD cable-box and a Bluray DVD player connected to the SAT/CATV and DVD HDMI inputs, the output is connected to a Panasonic TV which permits control over HDMI.
I noticed that by looking at the receiver’s display, if I have one of the inputs on, and the receiver NOT connected to the TV, I get sound, and the HDMI indicator along with the speaker pattern indication. But as soon as I connect the HDMI cable from the TV output to the TV, I hear a ‘click’ and the sound and HDMI and speaker pattern indicators go away, leaving only the volume number. When I unplug the TV, the sound comes back.
I did notice that If I unplug and plug back in the cable box a few times, It will start working, and the TV recognizes there is a receiver attached, along with a bluray player (I can now set the speakers to theater, and control the volume of the receiver, and I can also select the DVD player, the receiver switches its input and turns on the DVD player). The receiver will stay working until I turn off the TV. ( which is set to turn the HDMI connected equipment off) then the receiver won’t turn on again. I have HDMI.control to on, and tried setting hdmi.passthru to on, off and auto with no difference. If I set the TV to not turn off the equipment, when I turn off the TV, once I get it working, the receiver stays on, but this time when the source (the DVD player or cable box) is turned off and you turn it back on, the receiver again acts as if there is no inputs ( even though the receiver is still on)
What would cause the receiver to act as if there is no inputs when I connected the TV? And why when wiggling the input connection it would start up?
