Before buying a replacement logic board you may consider sending your logic board for repair. I sent many "spilled logic boards'' to an electronic shop in Ontario Canada and most of the times they were able to salvage the board. You'll pay about $200 for the repair and nothing if it can't be repaired. Check for these shops on ebay...

Here is the specs for your machine per the serial number:


Based on the serial number this should be the machine you have:


Ifixit and eBay have logic boards for this model. (ebay sellers in most cases are helpful in insuring you are ordering or bidding on the correct item if you go that route, just make sure shipping insurance is included )..... you could also order the 2.53Ghz version if a 2.26 is not available.

You might want to check the input for power to make sure that isn't the problem before replacing the logic board, i doubt it but worth checking. Here is the device page for you model:
