I don't remember if it was a resistor or some other part. He allegedly repaired it by replacing the component. Maybe if you take your machine apart and do some poking around you can find out what's causing it. If I remember correctly, someone else said he repaired his by soldering a bad connection on the logic board.
That's the answer I was hoping not to get, but I do believe you're right.

I just did a restart and I had to literally mash the screen brightness buttons (full-off to minimum) for about two minutes before the screen would stay on. This is one of the weirdest problems I've experienced in a long while.

If I hook it up to an external monitor in clamshell mode it should work correctly, right?
