[QUOTE="chscag, post: 1173898, member: 46727"] Welcome to the Mac Forums. If the iMac won't boot at all we can't really test to see if it's the graphics card that's failed, however, from the symptoms you posted, it looks like that's what happened. Which means a logic board swap out. Assuming you have Apple care, the genius bar will take care of that for you. If you don't have Apple care, prepare for an expensive repair. Apple does have a flat rate repair fee though so be sure to inquire about that. Since Target Mode boot is working, make a backup of all your data before taking the machine on in. [/QUOTE]
