I just ran a software update for Java and MacBook Pro SMC, now my Mini Display Port to HDMI TV is not working. The TV is flickering. The Mac Display is fine.

I was just watching / streaming TV off Safari on my actual TV.

I'm using a Mini-Display Port to HDMI cable for the connection to the external display.

Software update popped-up and said there was an update for Java and for SMC.

I ran the update and upon the computer restarting, my external display (my TV) is no longer working. It is now flickering.

It won't work in Mirroring or set up as an extended display.

I've reset SMC / PRAM / Safe Mode / Even restored from a Time Machine backup (From before the updates were done).

What could it be?!
