Puzzling behavior, straight out of the box. I have an Olevia 27" HDTV and an AppleTV (2nd gen) No problems when.... I set the source on my TV to HDMI and reboot/start up AppleTV. Problems when.... AFTER the AppleTV is booted, warm and happy, I change the source (from HDMI to perhaps the Tuner to watch TV). Bingo! Flashback to dying Nintendo days when after awhile, it would toggle-blink a magenta screen and the game loaded. Same exact thing happens here. The AppleTV will be still scrolling my screensaver photos intermittently as the screen goes black and sometimes magenta. When it alternates to the black screen (no AppleTV input, I gather) I see a NO SOURCE sign pop up on my TV. The only way to solve the problem is to reboot the AppleTV. I have googled to the ends of the internet and have found not a thread of evidence and reasoning why this occurs - help!
