MBP 15" mid-2012 Retina Display Issue

I've had a couple instances where I restart the computer and the display is black (no cursor) but the computer is on. The keyboard illuminated and beeps when I hit return indicating a failed login attempt I believe. If I put the computer to sleep by closing the lid, opening the lid results in a successful startup from sleep with the usual login screen.

External display (HDMI or Thunderbolt) are not recognized.

I've reset SMC and PRAM which have not helped. I disconnected the internal battery connection which someone recommended. This fixed the problem for the next startup but it has returned. Obviously, I don't want to continue to open the case to keep things running.

I noticed Apple had an extended display issue repair program that my computer was eligible for, but it expired in December 2012.

Is this a logic board failure?

Any thoughts greatly appreciated.

Thanks.

Yep definitely Logic Board failure. Repair program may still be active if you're lucky (4 years from purchase), though that's unlikely. It'd be best to take it into an Apple Store and see what they can do.
