MacBook Won't turn on but charging

Hi,

Can anyone help me please my macbook pro 17" unibody mid 2009 suddenly shut off and now its not booting at all. I have tried all Possible methods and keyboard settings but still no luck, I have even tried Victor Clausson method but also it didn't worked for me. Please help me if any one knows any solution, because its much expensive in my country to repair it. I don't want to give up on my laptop, so please please help me i am very desperate.

Thanks
