820-3787 GPU crashes after drop

Customer dropped this laptop and started having problems with the GPU ±3 months later. As a first attempt I've reflowed u9300, didn't help. Any suggestions on how to proceed?
 
Would a reflow of the GPU be a viable option in this instance? And how would I do this without messing up the rest of the board?
 
Well, if it was my board this would be true. As it's the customer's board, I would like to be a bit less destructive. So again, any advice on how to safely reflow the GPU?

Internet is full of videos about reballing.
A safe way cannot be described in few words.
I can only say reballing is NOT a solution for any GPU...
