Hi all, My system won’t turn on, The screen was black and the fan goes to maximum speed. Also doesn’t start after a SMC reset, and nothing working to boot the system. I see on the logic board a component 3R3 seems exploded, can this cause the problem?
Yes! Your logic board is damaged. The damaged component is a coil. You’ll need to find someone with the needed skills and access to the part to fix your logic board. There maybe more than this one part needing replacement. The other option is just replacing the logic board.
