symptoms : my old macbook pro stop to work after a hard day of work it was hot as !!@! and when i tried to turn it ON i heard the boooom from apple boot sound and then no screens … the screens remain black. i thought it was a graphic card pb as it wasn’t under warranty i bought a new one. as i have the opportunity to have the same logic board fo free i decided to swap it. in attach there is a picture of the NVIDIA chipset i think it is dead as there is a bubble sign on it can you confirm from this picture that the problem is really the graphic card that burned ? if yes i will do the swap if not i will put everything to the garbage. thx by advance for your answer!!! ps: your home toolkit is AWESOME !! i took off the logic board in 20 minutes great tools and topic
You’re going to have to replace the GPU; this one is toast. Reflowing doesn’t work long term, so it’s best if you just get it replaced. When you put the system back together to take the system in so you can get it fixed under the repair program, you will need to apply thermal paste so Apple can’t readily tell you were in there. Since Apple uses cheap silicone paste that barely works, it’s best if you do the same for appearance purposes. I’m sure Apple isn’t concerned, but it’s better to take precautions and take the available excuses away from them. If you decide to sell the system for parts, it’s best if you sell the parts individually (Just don’t sell the hard drive!). You will make more off the machine in pieces then you will as an intact system with a bad GPU. The motherboard isn’t good for much without a new GPU, but it can be used for parts or repair. Ideally you should also clean the heatsink and fans with canned air to make them ready for the new buyer to use, but this isn’t required.
