I just got the new Apple TV and get no signal from it on my HDTV. I have an older Samsung TX-p3064w which has DVI and not HDMI.

I used a DVI to HDMI cable but get no signal at all - just a blue screen which means the tv received no signal. I know that DVI is not supported, but I was hoping to use this before I had to buy another T.V..

The T.V. can do either 1080i or 480p using DVI. I tried using two cables and no signal.

Does the T.V. have to do 720 in order to give a signal? Is there a certain cable I should try?

Any ideas on why no signal?

    Apparently so, unlike the old unit, the new one only outputs 720p.

    I think this is my problem too. My T.V. will take any 720 signal and upconvert it to 1080. It seems like the Apple TV only produces 720.

    But isn't it possible to view the Apple Tv with 480?

    Same situation. Blue screen when I connect Apple TV using HDMI-DVI converter.
    Did anyone find a workaround for this?

    I have tried multiple cables in an attempt to get any signal and have had no luck. My guess is that the Apple TV only outputs 720. Maybe Apple will change this in the future?

    I was experiencing the same problem and discovered it is actually a 'handshake' issue. The firmware on the TV needs to be compatible with appletv. I solved it by updating the firmware for my Philips LCD 1080p tv. If you are using an older tv, you probably have to go to the manufacturer's support website to download the updated software on a gig stick and then upload it onto your TV. It should work thereafter. Good luck.
