Bringing Kids iMac back to life
1 - 3 Stunden
iMac was powering itself down or wouldn't come back up.
Wow, this was the most complicated repair I have done. It took about 2 hours. (but I had two young boys watching which extended the time.) I can't imagine doing this without step by step instructions and photos.
I was a little disappointed in the nut driver in the pro tech base toolkit. It needed about a 1/8" longer part of the skinny shaft to get to the recessed screws. I ended up leaving one of the screws out that connects the display to the case after about 6 attempts.
