Macbook Pro 2015 model screen goes black. Unable to power on

I purchased my Macbook Pro on 25th December 2015. A week ago suddenly the screen went black. I am unable to power on my Mac.

I take my Macbook to Apple Care. They ask me to pay 56K and change the motherboard else my Macbook won't power on

I never thought a brand which projects itself on innovation and customer value could deliver a product which suddenly blacked out and has inherent fault in it's motherboard

Please tell me guys what should I do?? Because I don't have that kind of money pay for the faulty motherboard, as I am a student
