I try to explain it better:
Scenario 1: TV on, receiver on. I'm watching something on receiver, everything is fine. I turn off TV, receiver turns itself off. I turn TV on, the receiver turns on. Everything is ok
Scenario 2: TV is on, receiver is on. I'm watching something on receiver and everything is fine. I switch to another HDMI port or to the TV channels. The receiver is still on but it's not currently on screen because there is another source. I turn TV off. The receiver correctly turns itself off. I turn TV on, the receiver doesn't turn itself on, even after manually switch to its HDMI port with the remote. The only way to turn it on is with its remote.
