4.3 Flicker Problem

My ATV2 had been working great until I installed 4.3 today. Now every couple of second there is a very annoying flicker on the screen. I have a 1080i TV. Any suggestions? Any way to go back to 4.2?

Mac mini, Mac OS X (10.5.6)

Same problem here... Bought my at2 in january... Plugged into my Sony grand Wega kf-42we620 using Rocketfish 4-port hdmi switch and rocket fish hdmi to dvi cable... Constant screen flicker... Every 2seconds. And video drops out every minute or so... Audio is also badly out of sync... This update has basically turned my atv2 into a useless ornament on my wall unit. Worked great before the update, even though the resolution was being dropped down to 480p.

I don't understand why my HDTV cable box and DVD play ok.. But atv2 is having so many problems.

Bad...bad...bad.

Honestly, I don't think apple will be too keen on fixing this one. All the problems are due to older televisions and non-HDCP compliant hdmi and/or dvi inputs. I checked my Sony tv manual... It doesn't say it's hcdp compliant. I did buy it 5 years ago and technology has changed.

I don't expect apple to address this unfortunately since we're probably a minority and it's not profitable for them to fix this. ***** for us though.

For those affected, there are a couple of things you can try:

1.

Reset the Apple TV

Resetting the Apple TV can be done by pressing and holding the Menu and Down buttons on the Apple TV remote until you see the Apple TV LED light flash. If this does not fix the issue then unplug the Apple TV from its power and let it stay off for a few minutes before plugging it back in.

You might also try resetting the Apple TV when it is both connected and not connected to your television (or when using the DVI-to-HDMI adapter). This may force it to change its output configurations and might allow it to properly set the output modes.
2.

Change HDMI output settings

In the new Apple TV software, go to the settings and to the "Audio and Video" section. Then go to the settings for the HDMI output and try different ones for your TV. The default setting is to automatically select the best option, but it may not be doing this properly. A number of people have found the system is stuck on the Auto setting, but if you can change it then this may help.
3.

Change your TV's resolution

Try a different display mode if your TV supports it. This problem seems to be affecting folks who are running at 1080i resolutions, so try changing the TV to 720i or 720p if you can. This may at least prevent the flickering while we wait for Apple to address this problem.

Has anyone tried the above steps? I will try this weekend, and if successful, will report back.

try the usual things.
rebooting both TV and AppleTV, disconnecting HDMI cable and re-connecting etc.

Any way to go back to 4.2?


no, you can't revert back to previous versions.
you can factory restore which might revert it back to the version is shipped with, but never any intermediate versions.

Mine is a a Panasonic CT-30WX54. Also a 1080i, but I have a scaling receiver. I hoped this update would fix the unit's propensity to downgrade the res to 480p (which I could "trick" into sticking with 720p by removing and reinserting the TV HDMI cable at the right time), but it's just made it unusable. I hope it's a hardware problem with the Apple TV so I can just return it for a new one.
