The Computer will give the happy boot chime then it will start to boot on the hard drive but the monitor has grey lines in it. The computer will keep acting like it is booting but never completely boot. It just has the circle go around and around on the monitor with the lines in it. I have rest the PRAM and PMU and the lines changing but still not booting. Tried to boot from external drive but it would not recognize the firewire. Tried booting in target mood to get the data off the hard drive. The computer trying to recognize this PowerBook did not recognize the PowerBook in target mode. Pulled the hard drive and was able to read the data off of it. tried to boot from the Tiger System disk but it would not boot from it. Tried to boot from the external hard drive with the option key held done but it booted the same as the internal drive did. Do you have any ideas of what part needs fixing? Thanks
It is definitely the logic board on the computer. Sorry man. It is the reason you are getting grey line on the apple logo and why you can’t boot to an external drive, internal drive or a CD. I am disappointed everyone jumped to conclusions about the hard drive when you clearly stated you were able to read the data off the drive. Also, it wouldn’t be the RAM because you hear the BONG!!!! which means the computer has past POST. (power on self test).
