backlight goes out after a couple of seconds
My LCD screen has a problem. When I open the computer, the screen lights up for about 2 or 3 seconds, then goes black. The screen is still on but dark. I took it in to a shop and they claimed they tested it with a new inverter. They said it needed either a replacement LCD or it was on the logic board.
Does this sound right?

I have hooked the computer up to an external screen and it works fine. That's why I don't think it's the logic board. The folks at the shop seem to think it's the LCD screen itself. It seems to me that the backlight would either work or not. They claimed to me that the circuit can "fail" when it heats up, which happens very quickly.
I remain skeptical. I don't mind putting a new LCD into the computer, but I don't want to do that unless I know it will fix the issue.

I just tried resetting the SMC as suggested. That did not appear to resolve the issue.
