Hi friends
I have a macbook pro mid 2015. A1398.
The laptop powers on but nothing on screen. And no "Chime" sound as well.
I have checked all the rails and all provides related voltages.
The black thin nylon cover on the PCH chip have sings of high temprature (some bubbles) and i noticed similar signs on the black paste rounding the vcore rails.
When powers on, all the voltages are pressent. The fan is idle even when the cpu starts to wam up. And the pch also starts to raise its temprature .
I do not know what to start with. As i suspect cpu or the pch chip.
Any advise?
Thanks
