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
Bu iyi bir soru mu?
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
