Thank you for your answer.
However, as I have never opened up a Macintosh before, I still have a few
questions. Is it enough to leave the Mac off for a day to discharge, or does
it need to be plugged in to a grounded socket for that? Can I also "wash" the
motherboard with water, as our kitchen is too small to have a dishwasher? And
are there other things I need to know being a newbie?
Thanks in advance,
Daan.
Btw. in case you wonder how I then knew it was Simasimac: I had visited that
repair guide and recognised the screen pattern and the delayed booting.
