Ответ на "Replace logic board or buy new MacBook Pro?"There are many posts and videos that state it has nothing to with AMD chips or how they are soldered. it all comes down to a bad capacitor on the circuit going to the AMD chip on the logic board. Replace the capacitor with a better one and it permanently fixes the issue. There are YouTube videos demonstrating that the capacitor is the issue and how to replace it. Paying for a new logic board only fixes the video/boot issues until that capacitor goes bad — and eventually it will. There are also many posts on ways to have the Mac OS stop using the AMD chip and only use the integrated Intel graphics. The MacBook becomes usable again — but with lower graphics capabilities. Google phrases about MacBook AMD chip fixes - bad capacitor - nvram fixes, etc to find the posts and videos.
