Q: 9 beeps "S.O.S." at start up. EFI ROM recovery mode

I have a mid 2009 17" macbookPro 5,2  (Model A1297) that will not start up properly any longer.

 

I am getting the 9 beeps "S.O.S." when I start up my computer and it takes an hour to recover and start. EFI recovery mode as far as I can tell, I have researched the issue and it seems to be the consensus.  

 

At this point I am going to look to replace the logic board. any other thoughts would be appreciated. I can not start in any sort of recovery mode due to this condition. So no diagnostics etc. I have been to Apple and they do not service my computer any longer.

MacBook Pro, OS X Mountain Lion (10.8.5), mid 2009 17" macbookPro 5,2 (Model
