Looks like something is up with my 2.2 ghz MBP dlsplay. It doesn't look like it's getting any power whatsoever. I was using my mbp and a 22" display - I shut the lid on the mbp and quickly reopened it and it won't come back on. The sleep light is a solid white when the lid is open and closed. I've tried resetting the SMC with no luck and when I plug it into my external displayit says "no power source". My first guess is it's a failed GPU because I can tell the computer itself is operating properly. Any ideas on what else I could try?
