I did this repair with a new cable bought from ifixit. I had previously replaced my earpiece speaker but didn't get my sound back. After replacing the cable though I have sound! But it appears that the dimming sensor might be faulty on the new cable, and I don't know if the internal screws could handle another opening.

A litte disappointed that I paid $25 to fix one thing but have another break.

Anyone else have this issue and any ideas?

Well at least I can hear through my earpiece again.
