Question Replace GPU on mid-2012 Retina 17"?


Feb 12, 2007
I have a Macbook Pro mid-2012 Retina 17". It recently froze several times, then started working again. Now, during boot up, horizontal green lines appear across the entire screen, and it consistently freezes on the initial boot screen with the Apple logo. I cannot boot into safe mode. Resetting the SMC and the NVRAM did not help.

I'm currently in Kerala, India, so I cannot take it to Apple. A local technician opened it up and said that the NVIDIA GeForce GTX 650M video card needs to be replaced because there was so much dust inside it that the GPU overheated, damaging it. However, this technician had relatively little experience with Macs I think.

We talked to another technician in a different city on the phone, who said he's seen this problem a lot in Macbook Pros, and that he can somehow fix the connections between the motherboard and the video card to make it work again the same day (which would be great because it would take weeks for a replacement part to get here). He said either way, whether we do his connection fix or replace the GPU, the problem will probably reoccur within 3 months to a year. I'm not sure, but I think he might have been referring to the known issue that Apple issued a video card replacement for for several other models, including the Mid-2012 Retina 15", but not the Mid-2012 Retina 17". I don't know if that issue applies to my 17" model. He said the issue was specific to the Nvidia GTX 650M.

Do you have any insights or advice about the situation? Thank you.
