My apple tv box power up when plugged in but my remote will not communicate, Why not?

Hello jerryl12,

​Thank you for using the Apple Support Communities. We see you reviewed an article titled Update your Apple TV, and you're running into issues using your Apple TV remote. We're happy to assist with this.

This link provides some great suggestions If your Apple TV remote isn't working:

"Try these steps first

1. If you have a Siri Remote or Apple TV Remote, charge it for 30 minutes using a Lightning to USB cable and a USB wall charger. If you have an Apple Remote, replace the battery. 
2. Unplug your Apple TV from the wall power outlet. Wait at least six seconds, then plug it back in.

If your remote still isn't working as expected, follow the steps for your type of remote. After each step, see if you still need help."

If charging the remote doesn't clear things up, check out the link posted above for additional steps that will vary depending on your exact model.

Best wishes.
