MacBook Pro 17" Unibody Hard Drive Cable
I forgot to fully press this home on reinstallation but it was probably at a less than 30 degree angle as when I later pressed the speaker fully home, there was a little "click" as the hinged retaining flap went back into place. This was checked later as OK while chasing a speaker NOP problem that was caused by the chassis earth near power connector being 180 degrees the wrong way thereby grounding the power amplifier of the speaker.
The title of this guide should be "Dock Connector and Lower Microphone". I ordered a new dock connector on the premise of one forum comment that said for a lower microphone problem "replace the dock connector as this part includes the lower microphone". All repair sites simply refer to the part as a "Dock Connector" when it really supports additional important functions.
I wish that I'd known that removal of the antenna without damaging it is an almost impossible task. I managed to succeed but in future, a clear recommendation to buy an new antenna with the speaker is suggested.
In my case, the grounding clip was taped to the camera! In addition, my repair process stopped at this step as the left screw on the power button had come out and was floating around next to the camera slightly stuck to the tape. This was lucky since a loose screw in an iPhone under the logic board would be a bad omen.
My iPhone was missing one of these screws, but the two left they came out easily. I also tried the half-turn technique but gave up after washers were jammed or on the wrong side. I had no difficulty removing these completely and refitting them properly.
Other than raiding a dead iPhone, does anyone know where I could buy two additional screws with washers?
Guess what happens when you rotate that ground connector 180 degrees...it grounds what I deduced to be the heat sink of the power amplifier for the speaker! So it is silent. It took me a couple of attempts to discover this as I was distracted by the new speaker not sitting down properly and a little dot of stuff under the main connector stuck to the pins. The latter was cleaned-off with a pin under 5x magnification followed by some isopropyl alcohol.
I suggest that Step 5 is more explicit about the orientation of this ground connector. It's only obvious after a really close look and if one has a lot to do like I did, it's a long time before one comes back to this step so the correct orientation is not obvious.
Fantastic Guide Guys! My parts came from the Aussie MacFixIt shop and were all good, and probably genuine. I had many faults to solve: Screen delamination in the bottom left corner, earpiece and main speaker distortion, home and power button intermittent, no phone mic at all, dock connector dodgy and the battery would die in a few seconds from 49%. Where I've got some value to add in the relevant sections, I will.
