How can I fix my display blacking out intermittently?

How can I fix my display blacking out intermittently? I've had the Apple Thunderbolt Display for a little more than a year, and it has started to intermittently go black for a few seconds at a time. When it does, I usually lose connection to my usb devices connected through the display. If I let it go on, it blanks more and more frequently until the system kernel panics.

See if disconnecting all the USB and firewire you have that might be drawing power. See it the issue persists or takes longer to go out. It probably is a power supply but something may be drawing to much power.

try external thunderbolt display cable. i hope that will solve the problem. the heat you are noticing on connector is coming from PC which lead to connector. black out issue will be solved after the external thunderbolt monitor cable from apple.

There was a firmware update that fixed the problem

"Hello everyone,

I've been experiencing the same or similar problems with my thunderbolt 27"" monitor. Lost the USB ports and the camera, then it started to flicker and soon complete blackout. Well I read about the cable and how it might be bad, but for whatever reason I didn't go down that road. I chose to replace the power supply. That seemed to work, for about a day or two, before I lost the USB ports and the camera again. Then the display started to blink on and off. Needless to say I was pretty bummed. I was researching and found this discussion board. Well long story short I disconnected the ""integral thunderbolt cable from my Mac mini and connected the monitor to the computer using a dedicated cable going to the ""aux thunderbolt port"". This was two days ago and everything seems to be working great. The only downside is that you lose the ""aux"" port. I does seem to be an issue with the thunderbolt connection inside the monitor. But that's a bit out of my league. Good Luck."
