Greetings, I have a 13" MacBook (White 2.0GHz/1 GB/80 GB) that will not boot. I've tried the troubleshooting tips on the Apple website to no avail. When I turn it on, the light on the front stays light, I can hear the HD spin up, etc. The screen flickers as if it is getting power, but no chimes or sounds whatsoever. I've also tried to reseat RAM, used different RAM, but no dice. I'm hoping that there are a few other things I can try before I'm left with getting a new logic board. Any ideas or suggestions will be greatly appreciated. Thanks in advance!
