We've had Apple TV for some time; worked great.
About 2 weeks ago it started acting odd. When it's turned on there is a lengthy time (2 -3 minutes) while pictures flicker on & off and there is some static. Then it shows the normal menu screen. If you try to select anything (like TV Shows), it goes back into the "off" mode, static & off - on pictures.
You can't use it at all.
