Heb je een tip voor andere reparateurs van dit (of vergelijkbaar) product?
Even if the owner says they have been to professional repairers, check the simple things first, in this case boot while holding down Option or Command R to see if it is still able to boot at all, then follow rigorous root cause analysis process.
