How do I find the part number for the logic board?

Trying to replace a bad hard drive, I broke the lcd connector off the logic board. I want to buy another logic board. Apple dealer told me they can't get parts because now it's "Vintage". Is there somewhere I can purchase another logic board?

Is this a good question?

For future reference, this is perfectly repairable at a fraction of the cost of replacing the whole board. And since it is just about replacing a connector (not hunting an obscure issue), it is sure to work AND last the lifetime of the board/iMac. Just find someone who perform microsoldering repairs and better if they specialize in Macs, so they carry the replacement parts and you can get the board back in working condition very quickly.

There are four logic boards in this series:

  • 3.2 GHz i3 - 661-5530
  • 3.6 GHz i5 - 661-5531
  • 2.8 GHz Quad Core i5 - 661-5547
  • 2.93 GHz Quad Core i7 - 661-5577

If you do a Google search Apple 661-5547 as an example, you should find a few offered up by sellers.

Just keep in mind the limits of the system after you repair it. You don't want to throw to much into this system.
