Acer new70 la5892p black screen intel sl6zs boiling

[reset1986]

hello, I have this motherboard that turns on, but from the black screen, I notice the bga sl6zs that becomes very hot,
I ran the reball on the bga but the situation does not change, do you have any suggestions?

Reballing wont help. You can try changing the PCH.
