My first pi, and i have it booting a debian distro fine. But the aggregation is video (hdmi) cuts out unexpectedly at different uptimes. Powering off and on video does not return. Waiting a while to power on video return.

What might be the cause?

Does only X die or do you see nothing at all? Can you boot without X and see if this works? Is the Pi maybe getting to hot? –  Lukas Knuth Jan 14 '13 at 18:54
    
See nothing at all. Unplugged and plugged back in and still can't see anything. Wait a while and plugged back in and can see again. I will check the temperature. –  Sean Jan 15 '13 at 16:50
    
if the temp is ok then check the voltage. elinux.org/R-Pi_Troubleshooting#Troubleshooting_power_problems –  rob Oct 30 '13 at 20:43
    
Have you solved this issue yet? If so, could you please create a self-answer and mark it as such. We are trying to get the Q:A ratio up and that would help us a ton. Thanks! –  RPi_Awesomeness Mar 3 at 17:58
