Water damage, Strange GPU issue
Hello,
I had a Macbook Pro without a backlight issue and I asked for help here
Water spillage no backlight, fused fuse?
Now I managed to solder another LCD connector and the backlight is back. The problem is now I'm having a strange GPU issue.
Whenever there is a change between the discreet GPU and the integrated GPU my Macbook freezes and won't work unless I reboot it. For example, I turn it on and everything works until I open for example, iPhoto or Spotify or Chrome. The other way around also happens, if I turn the macbook on with an external monitor plugged they'll work fine until I unplug the external monitor. In that moment the macbook will freeze.
Has anyone experienced this issue? It's clearly something to do with the switching mechanism!.
Thanks
Esta é uma boa pergunta?
Does someone have the schematic of this board? It's clearly a hardware issue that the switching is failing.

I downloaded the schematics but I'm overwhelmed by this. I have actually no idea where to start testing. I know the switch between iGPU and GPU is failing but no clue as to where this is in hardware
