My iMac will not display anything on the built in monitor. I have hooked up an external display to the thunderbolt port and it works fine on the external. I have tried to detect displays and it still cannot find it. I have tried a SMC Reset and PRAM Reset and also reseated the ram.


The specs are:


2.8Ghz core i5

4 gb of ram



iMac, Mac OS X (10.7.3)
