HDMI no picture

For the last several months I will jailbreak and install ATV2 Flash and everything will be great for about a week.  Then one day I'll turn it on to use it and there is no picture at all.  When I use the remote I hear the menu screen, but can't see anything.  Nothing fixes this except starting all the way over with jailbreaking and installing.  Help?

I am having the same issue.  I can stream audio to the player no problem but get no video output at all.  Any developments.

 

Thanks

I lost picture when I updated NitoTv restored an jailbroke left off NitoTv. Seems fine

I have the same Problem.

No picture after a few days of working.

Only plug off the power cable helps, but thats not a practicable fix…
