Dead CPU in a 2012 27" iMac?

crwdns2934249:0crwdne2934249:0:

I have a late 2012 27" iMac with the Intel i7 3770 CPU that won't boot.

The fan and the HD spin up but no chime and no display, only the first two diagnostic LED's light up I have replaced the PRAM battery and still nothing

Is it a dead CPU? It also wont enter Target Disk mode.
