Q: Apple TV not recognised by Panasonic Viera. Works with Hitachi on the same network.

What exactly does not working mean, please.

You may wish to try the following:

Press and hold the menu and the up button simultaneously on the remote for six seconds, the Apple TV should then begin to cycle through the various resolutions available to it at 20 second intervals.. If you see a picture appear up on your screen, use the remote to scroll down to the OK option and select it.

It's usually because the TV doesn't broadcast it's accepted resolutions and hence the Apple TV can't auto set it's output to match, which is where cycling the resolutions manually as suggested comes in.

As an alternative, you might connect it to another TV and try setting the resolution from the menu and then connecting it to the TV you are having problems with.

Have you tried 720p

Hi Reaser,

I have the same problem as you.

Have you found a solution?

Hi guys,

I have the same problem as you.

My Apple TV doesn't work on my viewsonic Tv.

Hi i hav the same prob too My apple tv 3rd gen has suddenly stopped working with my 42" panasonic led tv , model no: TX-L42E3B. When i connect it via hdmi to the tv there is no display at all. The strange thing is it worked on this tv perfectly until 2 weeks ago, but it still works with every other tv in the house. Does anyone know what i can do to fix this

I also have this issue with an ATV3 just purchased earlier today. I have been unable to get a signal to my Panasonic TH-L42E3S, which supports resolutions up to 1080p. The devices are linked directly with an HDMI cable, I have disconnected all other devices, updated the firmware on both devices, tried all combinations of ports, TV AV inputs, three different HDMI-cables that work with other devices, and cable directions. I have also tried cycling through resolutions from the ATV. Still the screen remains depressingly dark.

The ATV works fine when connected to my external samsung 24" monitor.

Has anyone had any success solving this problem?

The problem with my ATV3 described above seems to have been a hardware issue in my specific unit. I took it back to the retailer, where it was also not working on one of their TV sets. They exchanged the unit for a new one, which works fine.

thank you so much for putting this on here.  Something happened to my apple tv that it was only showing partly on the screen called

apple for support they couldn't figure it out since it worked on my other tv.  they told me to hold down the menu button and down button but

it didn't correct anything.  I did what you said holding down the menu and up button it was a bit weird for a while trying to get it to go to something but It WORKED!!!!!  YEAH!  I now have the full picture again.  THANKS SO MUCH.

Hi, similar problem here. I did the most recent Apple TV update, and now I am experiencing compatibility issues with my Panasonic Viera plasma TV (TH-42PD25). When the update was completed and the ATV restarted, my screen was cropped (see photo). I did the "press and hold Menu and Up button" to find a resolution that fit, and the only one I get is 480p. When I try to select 720p or 1080p manually, I get a bad image--with a distorted Apple logo streaming horizontally right to left. Does the latest Apple TV update have a problem determining my TV's resolution capability? Anyone have similar problems or know of any fixes? It's a shame my ATV can't find a resolution better than 480p on an HDTV. Didn't have this problem before the recent Apple TV update.
