Sorry... a logicboard is dead.. when its dead... there is nothing to check if the system will not startup.
if - as you said - all other parts will be ok - then its a faulty logicboard that has to be replaced.
in my company i do not need more than 1-3 days (depends on how fast its delivered by apple) to replace this part.
why waiting 4 weeks ??? :eek:
 
This is not Apple authorised service, so they are reparing the board not replacing it.

And how exactly would they actually go about repairing the logic board? A lot of computer repair facilities are really not equipped to do hardware-level repairs on complicated circuit boards - especially on modern boards, which have a great deal of surface-mounted components that are practically impossible to replace without specialized machines.

I seriously doubt that if the logic board on the 2008 MP is indeed dead that they'll be able to do much about it outside of sourcing a complete replacement. Likely, you're wasting time on the inevitable.
 
This thread scares me...I'm about to pull the trigger on a used 2008 MacPro from someone one state away, we've emailed several times over the past few weeks, and we've even become friends on FaceBook, so I feel pretty trusting in him and his offer. He's sent me several images of the MP, and even posted some video of the OS up and working, via Snow Leopards screen recording, since I won't be able to see it up and running when we meet face to face.

Is there any thing I can do or ask of him besides what he's already done, to make sure that logic board is working? He has no Apple Care on this box, as he never bought it because he works in IT and figured it would work on it himself if ever needed, I'm kind of the same way, but a logic board replacement right after buying this machine from him would be a major hit. He said its working flawlessly, so I should have nothing to worry about...the listing was found on Craigslist, and he's very weary of scammers as I am too, and so we built up this trust with each other over email and FaceBook.

Here is his offer...its a very nice rig for the money being asked.
I just worry about some catastrophe such as a bad logic board hitting me.

You say he's one state away? Set up a visit. Then you can actually use the machine before shelling out. Yeah you'll be using money for gas, but this way you can just pick it up from him and not worry about shipping costs. Shipping for a mac pro and 30" display would be super high anyway.

He doesn't want me to come to his home for the safety of his wife and kids, and I understand, craigslist has lots of weirdos, so we couldn't really think of another way to meet face to face and hook it up anywhere. He's actually going to meet me pretty close to the state line, so that was nice of him. But since I couldn't think of a way to see it up and running in person, I had him do specific things in the recorded video to prove it was him and it was that machine up and running, showing apple profiler etc, so I do trust him. I just get a bit nervous with threads like this one, maybe I should stay away from here.

That was a smart thing to do. If everything went fine, I wouldn't be paranoid, as the shots sent were something you requested, not what was provided blindly. ;)

BTW, the system purchased by the OP was from eBay's Polish site (seller lied on the description as working rather than DOA), not face to face contact. Apparently eBay/PayPal doesn't have the protection for buyers there that they do in the US (which really isn't all that wonderful IMO). :(

Ahhh I didn't know all that, and YIKES yeah I wouldn't want to buy from eBay where I couldn't see face to face on something like this, unless it was from Apple directly, face to face is about all I'd trust.

I still feel good about the deal. Heading down on Sunday. Then I have to start saving up again, so when the new MBPs come out, I can get one too.
 
I got my new logic board from Australia :)

I will rebuild my Mac Pro 2008 next week. My machine need to be send back from service.
 
Quit saying stuff like this...I don't want to hear about them going bad.

Dude, relax. You're getting all riled up over one user's experience with a 2008 MP that was knowingly purchased non-operational.

I have a 2008 that's had ZERO issues since it was purchased in Jan 2009 (so, over a year strong so far) and I have several friends and colleagues with 2008 MPs that haven't had major issues yet. While there's always a risk involved buying practically ANYTHING that's out of warranty, I seriously doubt you'll have problems. In my experience, MPs are well-built (server-grade parts, etc.) and designed for better reliability than you would find in a typical run-of-the-mill computer.
