Well, the seller didn't get back with me last night so I took it to the laptop shop this morning. The guy called me with a conclusive diagnosis: a bad inverter board, the thing that supplies high voltage power to the display backlight. He said he had the same problem on one shipped in from an out of state user last week. Anyway, Apple says unless I bought it from an "AUTHORIZED RESELLER" I am not warranted, and a lady in my office says she once lost the receipt for her computer and they would not help her. So, beware everyone. Don't try to save money when buying an Apple. I have not paid more for this eBay NEW unit than I would have direct from Apple. The repair, thankfully, is only $285 including labor. At least I know I have a fast, reputable place in town to turn to now if anything else happens, which hopefully it won't. And if all goes well week after next I will be enjoying Charleston, SC from 14 floors above whilst doing my iTunes thing... LOL. Thanks again for the quick repsponses. Looking forward to being back in the MAC community. Happy New Year!
