I must be the unluckiest guy when it comes to LCs.

Man did I get burned on this motherboard. It was not new. It was not sealed. It does not work. >

Looks like it was a return part never returned to Apple.

Since it was sold As-Is, I can't do anything about it. Sigh.

I get a chime, but there's a horrible sound coming from the speaker; almost like someone is adjusting their AM radio trying to get a signal. Anyone run into this problem?
