I also have a a crackling left headphone after this repair.

The left ear used to be dead, but after the fix it is back but distorting and crackling heavily.

Anyone have any ideas on what could be causing this?

Thank you very much

A great walkthrough.

Once completed, I did a reset of the PRAM, and it all worked beautifully.

Thanks again.

You guys rock!

Thank you so much for putting these instructions together.

I had a couple of tricky moments but my phone is working better than ever.

My frustrations have been eased and I couldn't be happier!
