I suggest a hard, amored look at the LVDS socket on the logicboard. When an external screen shows a clean picture, the GPU is not at fault.
I have looked at it, I don't really know what I am looking for, looks fine, but yes I agree that socket is probably faulty, and the only way I could fix that would be to replace the logic board right?
First I would try to clean the socket with a toothbrush and alcohol and then reconnect the cable. Sometimes they build up a film that makes for a poor connection. Replacing the logic board is expensive so we want to make it the last thing we try.
I'd at least give it a try. Would be careful about the toothbrush though, the pins inside are quite delicate.
