Reballed MUX. It solved everything.
It did work for a month or so now kernel panics re-appeard. Even worse than before (now with bot GPU. and much more frequent)
Any idea where to look this time?

Did you not replace C9560?

 

[WeLoveApple]

Yes, it was replaced with a standard non tantulum cap.

Another weird thing is that sometimes when I start it up without battery it only sees the external GPU.....

Seems like a MUX issue to me then. Reball another MUX from a donor board.
