Hi,

Just moved to a new place and so I reinstalled my HTMacMini (2009 nVidia 9400M model) in a slightly different configuration. My wife wanted it more out of sight so I put it in a drawer which had some ventilation but maybe not enough. After a week, tonight, it became impossible to wake up the display with the keyboard. I connected to the Mini via screen sharing and everything seemed fine. I rebooted the Mini and while I got a signal on TV, the picture was now flickering pretty regulary (as much as once per second). Again, connecting to it via VNC/screen sharing works fine. Did I screw it all up by not allowing enough ventilation in the new setup? Any way I can diagnose exactly what's going on? Could it just be the miniDP connector? Could I replace this? If indeed the display output is fried, how could I still put my Mini to good use? Would airplay to a new Apple TV be a solution (my TV is 1080p)? I know it can replace my Mini to watch netflix but I have a pretty large collection of mp4 and mkv videos. Could these be streamed by the Apple TV if a HD is attached to the Airport Base? Thanks !

Insufficient ventilation is definitely bad. However, have you considered opening it up and making sure it's not full of dust?

He is right might have a lot of dust inside. Clean it out with a compressed can of air.My friend did this and the problem went away.

As well as making sure the vents/ducts are all clear, I stand my 2009 mini on a CD case, to raise it another 10mm off the deck - which must help the ventilation too.

Thanks a lot for your help. Turns out it was my HDMI adapter (a complicated one with the audio coming from the USB) that crapped out. Since I now route the audio to an AV receiver, I just replaced it with a regular HDMI cable and all is back to normal !
