Old pioneer + Apple TV via HDMI not working
Hi! I am trying to set up a Pioneer PDP 4270HD with apple TV 4K drectly via HDMI port from Pioneer to Apple TV and I get absolutely nothing. I followed the instructions in the original Pioneer manual, chose the input (5), pressed home menu, Option, HDMI Input, chose Video and tried each video signal choice under HDMI input and none worked, including auto. I then tried moving the HDMI cable to the other port (input 6) and did everything again - but again, I get absolutely nothing - no picture/no sound. It seems as if it should be so simple - but its not, for some reason. I checked all of the threads, but their circumstances were different as I am going directly from the TV to the Apple TV without any additional equipment. I would greatly appreciate any help you can provide in trying to figure this out.
