When I got the dreaded "flashing ?", I thought it was the Hard Drive and replaced the drive. That didn't fix the problem, so I assumed it was most likely the cable and ordered it from iFixit. To make the install a bit easier, I got the cable with the IR sensor/sleep LED bracket already attached. I also added electrical tape over and under the new cable to protect it.

The repair was easy and went very well, and best of all, it fixed the problem. I booted the computer up in OS X Internet Recovery mode and restored the system. It's working fine.

I'm a 73-year-old women. If I can do this, anyone can. Read the instructions, watch the videos, and just do it
