Apple TV.2: Time & Date Set Up Errors

Hi, I bought the newest version of the Apple TV in Panama and took it with me to Venezuela. Every time I try to "hook it up", it never adjusts the time and date setting and simply says "Activating" until it goes to sleep. I've had it for a long time now and I haven't had the chance of using it. Other methods online talk about turning off Firewall, or just letting it sit there until it adjusts but I can't do "let it sit" because it will go to sleep. Hoping for your reply/hint. Thank you.
