Chosen Solution
I am once again trying to fix a powerbook that I have hanging around. I press the power button and the machine bongs but that’s about it. The DC in board I believe is fine because I see the green light on the power adapter. I started the machine without the battery and it bonged. I changed the DC to DC in board and the hard drive but that didn’t work either. I took a flashlight put it behind the screen by the apple logo and I didn’t see any faint graphics. I was wondering if anyone else would know some trouble shooting solutions. Also, is it possible for the computer to bong with a bad logic board? thanks!
Hook it up to an external monitor. If this works, you have isolated the problem to the screen area. Boot it in Target Mode to another Mac and run diagnostics on the hard drive. Do you have a history on this machine?
