Hi first of all thank you for your help. The macbook is back alive. Yay! But no image so will check it now.
Thank you for your all help. Now the computer boots. But there are other issues I found out,Keep in mind, you've already injected 12V into CPU!
Possibly no repair on this board.
Nothing to lose however; give it a try with new chip.
And don't do same error next time...
