There was no sound coming from the speakers, and the headphone jack's Liquid Contact Indicator (LCI) was pink. So I wanted replace the headphone jack.
The repair went pretty smooth. It was my first repair, so I was nervous about damaging something. Unfortunately, the part I received was defective (not from iFixit), so I put the old one back. Crazy thing is it ended up being a software issue with the iOS. But it was a good device to start out on.
Watch the clips on the iPad they can break easily. If you're repairing for the first time you may want to order some replacement clips.
