I have had my Apple TV 4 since shortly after its launch in 2015. Tonight it suddenly wouldn't "display," when I select it for my TV. I tried unplugging HDMI, resetting it via remote command, and unplugging it. You can hear sounds such as when you go to home screen. I thought it could be my HDMI switch so I tried plugging it directly into another HDMI port on the TV with new HDMI cable, same symptoms. It won't display though it appears turned on and fully booted up. Was there an update this week that could have caused this? Has anyone seen this before? Any solution? Thanks!!!
