Do you guys repair the headphone jack

Hi,

ifixit does not do repairs to equipment.

We are all volunteers who will advise you on what you need to do to fix the problem yourself.

Here is a link to the ifixit Dell Inspiron 15-3521 Motherboard Replacement guide. This will help you to gain access to the motherboard in your laptop so that you can remove / replace the audio (combo headphone/mic) jack.

You will need SMD soldering expertise and tools to effect the replacement.

Here is a link to just one supplier of the replacement part. It is a very hard part to find for your model as most places are out of stock. This is the best that I could manage. You may have more luck in finding a supplier that suits you better. Just search for Headphone MIC Audio Jack Socket Connector for Dell Inspiron 15R 3521

If you find that doing the repair is too daunting, then I suggest that you contact a reputable, professional laptop repair service and ask for a quote to repair the laptop.

Hopefully this is of some help.
