I've no idea how to trigger this behavior, but on two occasions, while AppleTV was syncing with iTunes over Ethernet, I tried to play a movie (encoded as a MOV file through Handbrake), and the Apple TV's just started flashing. The whole picture would keep going from the image to a black screen, every second or so.

I'm assuming this as a HDMI handshaking problem, simply because it seems to be fixed just by unplugging the HDMI cable at the back, and plugging it in again.

This occurs on either 720p or 1080i but not 480p (which again backs up that assumption). TV is a Sony XBR2 40"

    I have the similar problem. When the Tv was first set up the video was great. Now the screen flickers, like my PS3 does from time to time (HDCP issue?). Once it starts to flicker the screen then goes black. I have a Samsung LN-4095SD and an Onkyo TX-SR804. The TV is connected HDMI to Onkyo and Tv is connected to Onkyo. Tv was running great but now, it's become an issue. Is anyone else having a problem like this?

    Same thing just started with mine. Unplugging the HDMI didn't correct it.

    I put it on stand by because the thing is hot.

    It's disappointing - worked great for 36 hours and now an unexplainable issue.

    This is definately a HDCP problem and I've called Apple Support about this. If you switch to 480p it works fine (which would make sense since 480p shouldn't need to use HDCP).

    And no the unplug/replug doesn't always work - it does work if you see an apple logo after you plug it back in - but I don't know why it does that only sometimes and not others...

    Please call Apple support, since they claim they've "not heard about this problem"...

    I'm sorry Apple.

    So I went to the Apple store today and they graciously replaced the box with a new one - the "genius" asked me about a power surge etc. I said "look pal I'm totally technologically proficient...there was no power surge". He was nic about it but what nerve!

    Hooked the new unit up and the same flashing happened. Tested it on my DVD player that has a HDMI port - same effing thing. At that point I realized it likely wasn't an Apple issue... and it isn't in my case. Turns out the issue is a fairly well documented issue with my DELL (figures doesn't it) flat screen TV.

    My suggestion is to check out the manufacturer's website related to your TV and see if there is an issue. Unplugging the TV for 5 minutes reset the TV and resolved my issue albeit temporarily based on the Dell website. That will be the stop gap for me until DELL comes and fixes the thing.

    I am having this problem with my TV too its a 40" Sony XBR2 connected via HDMI. I dont have this problem with my PS3 which is also connected via HDMI so there must be something strange with the way that the Apple TV does its HDMI handshake .

    I have an LG 30" SuperSlim CRT HDTV and I am having a similar problem. When the Apple TV is syncing or downloading a trailer from the internet the video gets horizontal lines all through it that kind of looks as though the video is interlaced (the ATV is set at 720p) and the refresh rate is just not high enough to keep up.

    Dell 42 inch - same problem. It works for several hours then starts to flicker. I HAVE been able to get rid of it by unplugging the apple tv and the hdmi, waiting a few seconds then reconnecting. Apple, how many posts do you need???

    Hmm...this happenned to me over the weekend, but only during one movie--out of several movies played. I'm really not sure of the cause; though, I didn't have this problem before setting up AppleTV. For now, it remains unplugged when not in use.
  • Dean W. Level 1 Level 1 (10 points)
    Glad I'm not the only one then - So we have Sony's, Dells, and Samsung with HDMI problems on both video sync and now audio sync...

    I've reproduced this just playing a music video on iTunes, but it seems to be irrelevant - it flickers on the main menu with nothing playing!

    I can't deal with this in anything but 480p, which really makes me somewhat tempted to return it (unless we see a fix promptly).

    What really bites... my TV is the same Sony Bravia they show in the AppleTV adverts!

    Oh, Philips 37" LCD HDTV here.
  • klaushof Level 1 Level 1 (0 points)
    Same problem here. After 15-30 minutes it starts flickering, regardless what is done: synced photo viewing, or streamed music or plain main menu. No other HDMI device (DVD, PS3, AV Receiver, MediaLounge) shows this behavior. The Apple TV is connected directly to a Sony Bravia KDL46XBR2.

    Can someone from Apple tell us if this is under review (perhaps there is a SW fix?), or does everyone has to go to the Apple store on this? I am happy to wait for a while, but an indication that it is worth it would be good.
