Just today ATV would not show anything on my TV. I rebooted ATV by unplugging and re-plugging but that was not the problem so I took the HDMI cable out and plugged it back in which resolved the issue. I really do not feel like buying the new model especially since my model works just fine. Does your ATV HD do this sometimes as well? Require you to either reboot the unit, or unplug the HDMI cable? Thanks..
