My 2006 17" MBP was apparently dead. I took it to two Mac repair shops in my city and they both told me I needed a new logic board. The problem was that when I turned on my MBP the fans would come on but no screen and no beeps or anything. The light on the front stayed solid white. I tried resetting the smc, resetting the pram etc... I even took out the logic board to see if something obvious was wrong. I had no idea that the white light staying solid meant anything until I read on a forum that if you have bad memory the light on the front will blink a few times. I decided to take out the memory and turn it on to see if the light blinked or stayed solid anyway. When I started it up with the memory out, sure enough the light blinked. I put the memory back in and started it up and all of a sudden everything worked again. I have no idea why that worked but I'm glad it did. It hasn't worked in a couple of months and now everything is great. Maybe someone else in a similar situation can benefit from trying this as well. Let me know how you make out or if you know why that may have worked
Cheers!!
