Hi, So I have a 12" 1.5GHz PB (no applecare) and it has completely become useless due to the fact that the LCD has lines vertical and horizontal and you can't even get to the third stage of the setting up process (I reinstalled Tiger) without the screen completely going out of whack and the gray screen of death comes up. I have been through eight iBooks while I was in school. They all had issues with logic board which kept occurring due to previously poor repairs, so I can sort of assume a similar problem is happening. Some things I have tried already: Zapped the PRAM Re-Installed Tiger Checked the HD (works fine in Firewire Mode) Threw it down a flight of stairs (just kidding) Next possible steps: Use iFixit.com as reference to take apart, and see if I can diagnose a bad cable/connection Cry if I mess it up more Buy a new MacBook Pro and smile Anyway, I thought it might be more than one problem which is the reason the display freaks out and I am guaranteed to get the gray screen. Has anyone else had this problem? I think this little PB will turn into parts for sale if the fix is beyond its worth... Cheers for your time.
