Hello,

I had the same issue and it was because of a cable.

Best regards,

IIRC there is a setting in the service mode that can switch the setting for the dvi socket

might be worth giving that a go, after reading the service manual 

Thanks guys for the suggestions! :)

Here's an update: I've tried different HDMI cables and also different DVI-adapters - but to no result. Stills flickers.

But... we have a newer ATV (the first without optical signal) and when I connected that one using the same cables the flickering stopped.

The mystery thickens.

The same in my case

BV7-32 with ATV2 all good but no streaming (HDCP error)

BV7-32 with ATV3 flicks every 2 sec with all cables.

BV7-32 mk1 (DVI).

Interesting - in my case it’s the opposite. ATV3 gives no flickering, but ATV2 does... But ATV2 have sound, which the ATV3 doesn’t (no optical output on that model) 

My bad! The ATV that flickers is a G3 and the one that doesn’t is a G4.

I believe you can buy an adapter for the Apple TV that splits the video and audio from the HDMI output. That way you get the HDMI to DVI for video and audio via the optical/digital output.

My BV7-32 can show ATV 3rd gen with no flicker. Adjust the video output in ATV3 menu
