I suspect a cold solder joint in the video circuitry, actually. My machine is fine now, but the screen problem happens sporadically after an hour or two to warm up. It was happening last summer, was fine over the winter, and then happened again a couple of weeks ago during a hot spell. It's probable the dealer couldn't find the problem because (a) the machine was in an air-conditioned room or (b) they were running it with the top off... A friend has exactly this problem with his Mac Plus... Now, how to get the problem to manifest itself in front of a technician...
