Flickering every 30 sec and disconnecting external divices
After a few minuts the flicker increase and finaly it is going mad. The same thing happens if I connect it to the thunderbolt port on an other screen. I have seen desciption of a problem like this, here and on others sites, but never seen a solution. It seems that a lot is struggling with the same problem. Have any here in this forum changed the power supply or the logic board. I have seen answers like, change the thunderbolt cable, reset the nvram and smc, and I have tried that too. I have removed the external devices one by one but the problem still exist. I have now bought an Eizo display so I am able to work, but I would love to have the Thunderbolt display back and alive. It is connected to a Mac Mini 2,7 GHz mid 2011, and to check it I connected the display to both an iMac 27" and a Mac Pro. I would love to fix it myself, with help from IFIXIT I have installed an SSD harddrive in my Mini Mac and Mac Book Pro with succes.
