Please, please, please…Please! Make sure you fix this cable somewhere where you can get to it when you put the mother board back in. it is a pain to screw it down and realize that it’s under the motherboard. Learn from my pain.
I had to pinch the 2 sides of the left speaker cable while pulling down. I didn’t have to do this with the right speaker it came out with no problem. The left was a little tougher, but you have more clearance and can use your fingers on the left speaker cable.
I finished this in about an hour. The video left out a LOT of steps and looking at the written/pic guide was essential. If I hadn’t done it backwards or looked at the pics/written guide first I probably wouldn’t have broken the power button connector…either way you can put it back on after broken and it works fine…but it would have been better not to have to do that. Learned my lesson…learn from the comments!!! Also I did NOT take out my ram the whole repair…and my iMac is fine but listen to the experts dont do what I did…you may not be as lucky!
