AVR switching inputs randomly when watching satellite

[maverick22]

My Denon AVR/TV is randomly switching inputs when I'm watching DirecTV (satellite service). Everything has been working fine the past few months. Sometimes the AVR is a little quirky (DirecTV remote won't turn on TV and AVR, sometimes it does), but this issue is new.

This issue just started a few days ago though where we will be watching DTV, and it switches inputs out of nowhere to the TV input on the AVR. We have to grab the Denon AVR remote and manually switch it back to CBL/satellite.

Any ideas?

I don't have 4k service through DirecTV so I'm using a standard old HDMI cable. It had been working fine. Do you think you need a certified premium high speed HDMI cable like the rest of the components in my chain ? Could that be messing up my whole chain? I hear things are picky when it comes to 4k. Like I said they have been mainly fine the past few months though. This issue came out of nowhere.

I have tried unplugging everything, and that didn’t help.

Thanks in advance!

Thanks in advance!
