AppleTV interrupting while playing movie My new black Apple TV (3rd generation) is plugged into my flatscreen by HDMI. All worked fine. 

A few days ago there were sudden "interruptions" while watching a show from netflix: no video, no sound, black screen. After a few seconds, video and sound returned, my screen shows a message that it is connected to a HDMI source.

From that message, I understand that the HDMI connection was lost. ATV has the latest software, the interruptions come and go, no pattern to be detected.

Anybody know what I can do, apart from returning the ATV and getting a new one?
HDMI connection lost


Could mean that the HDMI cable is not having good contacts on the pins.

The only way to test that is to get different HDMI cable.

Apple also provides some instruction on how to fix it.
