Hi. I recently replaced the headphone jack in my 7th Gen iPod Classic. I used ifixit tools and instructions (very helpful, BTW). But, there’s only sound coming from one headphone still. I’ve tried several different headphones. Could it be the logic board? I saw something about fiddling with the prongs inside the jack? Thanks.
Try this and see if it fixes it. You may have bought a defective one.https://youtu.be/N24xtlqvYu8
