My mac was running fine one day then suddenly powered off and tried to restart itself. Upon restart it was stuck with the loading status bar and the screen had 5 vertical pink lines across it.
Having done some research it is most likely a GPU solder issue which can be fixed by reapplying thermal paste or by 'frying' it in the oven. https://www.youtube.com/watch?v=nB172HJeM0w
Although some have said they have fixed it via safemode/updates etc
Just wanted to ask on here before I go ahead with the baking method as a last resort.
-I cannot get my mac to boot at all and cannot get in to safe mode.
-I created a bootable USB stick and that would also not load using Apple+R.
-Cannot boot from my(external HDD which I normally use instead of the internal drive/os
-The pinks lines do go away when it attempts to enter recovery mode, which does give me some glimmer of hope that it's a software issue and not hardware. But it just gets stuck on a totally blank white screen before it gets to recovery mode.
I guess one thing I haven't tried is putting an actual DVD in the drive, but I threw those out years a go so would mean sourcing one.
Any advice would be greatly appreciated before I start trying to take it all apart!
It's an old model too, and I really only use it as a display for my newer MBP. So not worth paying to get it fixed
