Its actually a A1015 1.33GHZ, maybe the logic card died, but it would be a big coincidence that it just died when i opened it up. I usually feel comfortable with fixing computers on my own, but since i messed this one up, it would feel better if someone else fixed it for me. And i can't use iFixit because i dont even know what the problem is.
OK, A1015 then. Coincidences like this happen all the time. I have had multiple parts fail in a line. I've had other parts indicate failure but take ages to die. I had one USB 2.0 card fail and it caused kernel panics and font issues! Just the way it goes.
But for your peace of mind then, check your connections. Open the PB back up and go through iFixit's guide for hard drive replacement and check that you have everything right. If you're confident that it's all correct and the Mac still refuses to boot then it's another issue.
There's nothing in that area that would cause problems. The only ribbon cable close to the drive ribbon cable is the one for the sound board. There is another ribbon cable that's higher up next to the left speaker but that's for the DC-Inverter board. I suppose if that was disconnected there may be a failure to boot, but that cable is quite a ways away from the HD bay.
Even if you had a screw rolling around loose, unless you are a person who has REALLY bad luck it would not affect things.
But mainly, any issues with the HD would result in either the drive not being readable, disappearing on you or otherwise being inaccessible within the OS. It would not stop a boot.
Perhaps, and I am speculating, part of the previous HD issue was actually triggered from the logicboard?
I say thing because I have an iBook G4 1.33Ghz that was a friends. At one point he thought he had a bad HD, so he replaced it with one I sent him. When he gave me the iBook I experienced freezing and a disappearing hard drive from the desktop. He took a look at it and the connector for the HD on the logicboard was damaged. The only fix here is a new logicboard.
However, all of this said, if this is still something you'd rather trust to someone else, then the only thing I can suggest is looking up Apple service providers in your area. There's bound to be a shop somewhere. It'll be expensive though.
