Mac Book Pro - Logic board stopped working

I Had purchased Mac Book Pro before around 14 month from one of the apple store. It just blinking and doesn't start. As per customer service they ask to replace logic board and It costs almost around $650 (38500 Rupee). And my warranty is just expired before two month. I believe that I got defective model of Mac Book Pro, As In My warranty period also there were such issues and it was issue of hard disk.

I am a normal user regarding to use Mac Book. I don't do gaming and etc.I just use it for my professional purpose.

I can't pay this much amount again in around one year duration. Please suggest what is alternative or what can I do As warranty is expired.

Thanks.
