So I'm having an issue with my Yamaha YHT-497BL Receiver, whenever I turn on the TV the receiver will switch from the HDMI input it is on to AV1 for some crazy reason. My cable box and PS3 are plugged into the receiver and then the receiver is connected to the TV by one HDMI cable, so the only thing actually plugged into the TV is the receiver. Nothing is plugged into AV1 on the receiver so I have no clue why it would be changing channels?!
When I turn on both the TV and the receiver everything starts perfectly fine but about 5 seconds later the receiver will just switch inputs. The TV is brand new but I've actually had 2 different sizes of the same TV (a 46" and a 55") and it did this on both TV's so this has led me to believe that it's a problem with the receiver. It's not a huge problem, just requires that I switch the input back to HDMI1 every time I turn on the TV, but it's certainly an annoyance that I would like to not have to deal with if at all possible.
If anyone here has any troubleshooting tips on how I may be able to correct this please let me know! Thanks in advance for you help!
