Apple TV 3rd Gen a1427 issue
I have recently restarted an Apple TV 3rd gen a1427 which has been boxed for several years. The unit powers up and there is an output on the HDMI. With a new battery in the remote the indicator light on the Apple TV flashes when the remote is used but the remote actions have no affect on the Apple TV. I'm presuming that the remote needs resyncing some how but how do I do this.
Many thanks
