Q: Mac Mini 2012 video blinking out

Yeah, if your blinking every six seconds there is something else wrong. I always had blinks about 10 to 15 min after startup. Updated and haven't seen any blinking yet.

Done. It seems to be a firmware or hardware issue since it blinks also during bootup or in recovery partition. Tryed everything: changing cables (all high speed HDMI 1.4 certified), hdmi ports etc. No way.

MM 2011 perfect without any issue as all other my HDMI equipments: MySKYHD, PS3, Blu Ray Player. My new MM Late 2012, instead, blink every 6 seconds!

Was it acting like this before the firmware update?

BTW, great AV reciever

Yes, nothing has changed after the firmware upgrade

Just curious, which way did you get your firmware, through update or website? I seem to remember that if one doesn't work sometimes the other does, but that might just apply to OS X updates.

Trough update. I've also tryied to re-apply the update downloading it directly from the website but it recognize that my MM is just updated and didn't re-apply.

So glad they're working on it and acknowledging it.  Sorry if others are still having trouble.

Don't know why it doesn't work for me, but nothing has changed after the 1.7 firmware update. Obviusly I've rebooted many times, powered-off, disconnected and re-connected HMDI, powered-off and on the AVR and the TV: nothing.

I've also reset the NVRAM and PRAM.. same. I think there is something not working well in the HDCP in these late 2012 mini.

After update:

Boot ROM Version:          MM61.0106.B03

Firmware updated over 3 hours ago, so far no blink. Color me optimistic.

Not sure whether to update or not as my replacement MM hasn't blinked once or given me the static/shash screen for a week now?

What to do?

If you don't need the update then what improvement will the update make?

You can always update later if needed, but once you update there is no going back

Great to hear john, hope it holds up.

Philip,

I agree with MyMac8MyPc... If its not flickering, no need to update. The update will always be  available if needed.

However, perhaps Apple installed the firmware update on your replacement Mini before they sent it to you... Maybe worth checking your BIOS Version as shown by John Rankin's post above.  Apparently the update shows as:

Boot ROM Version:          MM61.0106.B03

Cheers

I don't think the update is available if it has already been applied, but doesn't hurt to check the Boot ROM Version.

Good idea
