Starting Chime Sounds Repeatedly Light On No Display Macbook Pro 15 Unibody Late 2011

Chosen Solution

So, my MacBook Pro makes the starting chime, but nothing happens, after about 5 seconds, again the starting chime sounds, but nothing happens, there is no display. This happens continuously.

Not good :-{ This is a common symptom when the discreet GPU chip has failed as the POST process fails to complete so the system resets and tries again getting into a loop. Shut it down, this time on the restart quickly press the T key which will put your system into Target Disk Mode, which by passes the discreet GPU POST process. Did you get a FireWire or Thunderbolt Icon on the screen? If you did that proves it.
