Have you tried an external monitor? See what the video looks like there. If it’s fine, you’re likely just looking at an issue with your screen or the cabling. Check it out and let us know!
I had the same issue with my MacBook. Apple told me the logic board was broken and would charge £550 to replace it. Luckily, i managed to get apple to fix it for free.
What I meant was have you tried hooking an external monitor up to the MacBook?I have tried to connect via Finder's View option. The MB seems to be dead when in this state as it never responds to any incoming connection requests. It did before so it's not a firewall issue.
How did you manage to convince them?
I dont have the hardware to connect a monitor. Best I can do is try to reach it via the network.What I meant was have you tried hooking an external monitor up to the MacBook?
Thanks. I will give it a try!They initially took it in to try and re-install the OS. They then replaced the logic board of their own accord when they were looking at it. I was only told they replaced the logic board when i collected it. They did try to charge me when i collected my laptop, but i said i never agreed to pay for it. The genius guy spoke to his manager and then agreed i didn't have to pay. I did have tell them they could keep the laptop because i would not pay for the repair. (it would make more sense to just buy a new laptop than pay the repair fee)
I have read other people having the same problem, so it leads me think this is an unofficial problem. Just try and get them to take it in without paying for the charge. this would be my advice.
