No Sound from Mac Mini!
I have a new problem that involves no sound coming out of the Mac Mini's speakers. When i received my Mini from the seller there was a gap to the rear of the unit as the party before me did not reassembly the top cover all the way. I gave it back to have the cover fitted correctly and now after powering on the unit I recognise that there is no sound, and plugged in some external speakers and got sound for just about 2mins then a lot of static. I then purchease a putty knife filed the edges and opened the case, but I found nothing that seemed like it was out of placeso I reassembeled.
I had the same problem with a Core Solo machine. Turns out the people who installed some RAM (this was before I discovered ifixit) had not properly seated the ZIF cable in its socket.
Steps 7 and 8 in the Audio Board install (Installing Mac mini Model A1176 Audio Board) are where the solution lies.
There is a painted line on the ZIF cable. Before you close the cable lock, make sure the cable is fully inserted - the painted line will be about 1mm above and parallel to the top of the socket. Push down the clip and all should be well.
