Q: Thunderbolt Display Issues

HI.

 

I'm having issues with my Thunderbolt display recently.. issues started about a month ago and a call to Apple support wasn't very helpful.

 

My display is periodically loosing connection to my Macbook pro. onboard display ports (USB, Network AND Firewire) are disconnecting and about a minute or 2 later the display start frantically flashing. Rebooting the laptop or unplugging the display clears the issue but it usually returns after 5-10 minutes.

 

I've reset PRAM and SMC memory but this has not helped. Can anyone give any ideas?
