HDMI Handshake problems every 20 - 30 minutes - Color Inversion Issue

Dear all,

I used the old ATV for a long time and never had problems with it. Yesterday my new ATV 2 arrived. The setup was very easy but after a few minutes a problem with HDMI Handshake occurred and repeats at least every 20-30 minutes:

I get a green screen for one or two seconds and then the picture appears again with some kind of inverted colors.

I use a Philips 40 inch 7664 LED LCD with the newest firmware installed.

Any idea what I could to to fix this issue?

Thanks

fyi, both Apple and Philips know about this..


I opened up a bugreport at Apple, I got a request from the engineering team at Apple to return/debug some values running a snooping timer app which I did on Aug 3rd


I also opened up a bugereport with Philips and gave them both eachother's bug ID's so they can work it out together..


No update on this yet, but they absolutely both know about it and are hopefully looking into the issue..

Yeah except the problem is that with a forum thread where a lot of people are (understandably) yelling "It's not working" isn't very helpful in a tech/debug kind of way...


So to make sure I supplied both Philips and Apple with as much tech info, reports, ID's and test-cases on how to reproduce as possible..

Might speed up the process 🙂

In the mean time I'm waiting for my HDMI To 5 RCA Component AV Converter to arrive..


About $50 on E-bay, will downscale the image to 720p due to the limitations of the YPbPr input of the Philips TV I use, but at least better then the inverted green screen due to HDCP handshakes (since YPbPr is analog)


So hopefully that will be a stop-gap solution until the real issue is resolved

Well, I use the audio from the mini's S/PDIF port to an amplifier, so I don't use the red/white connectors for the sound. Can't tell you what the loss there is.


The image is slightly off color-wise but if you use your mini as a media center it's hardly noticable. I did notice an occasional square fractal.


So the image isn't as clear and crisp as a true HDMI throughput, you're converting the signal to analog after all (so keep the YPbPr cable as short as possible for quality reasons), but it's 20x better then the random pop to a green inverted screen.


Also, I had to move the screen a little to make it fit the TV perfectly and use the overscan bar in the display preferences to make the image a little smaller.


So yes, there's absolutely a little loss in quality, but it's still 1080p HD (may vary for your TV set though, Philips told me it was limited to 720p through component, while it turns out to work fine on 1080p in the end) without any nagging HDCP handshake problems.

My "interruptions" were in the home sharing side of things... airplay of music, itunes movies form my own collection, etc


AppleTV was saying that I had current software...


I just (9/21/11) ran a full "Restore System" on the Apple TV... which by default also fetches current software update.


Today no issues with dropout.


Another suggestion for some users: AIrFoil by Rogue Amoeba Software. Great little app for streaming music around the house to almost any device
