Where can I find a repair shop in NYC for these speakers?


I bought my speakers maybe 4 years ago, I have not used them in 2 years but when I recently tried to use them they were not working. It seems that either the battery died, the charging port got damage or the charger does not work, but basically I cannot use them because it does not charge.

I would like to find a list of repair shops (considered good by Harman/ Kardon) in NYC to repair it. Is there a repertory somewhere?

I would really like to use them again!! Thank you for your help!

Hi @slc1994 ,

Given that the battery hasn’t been recharged for 2 years, it most probably has become depleted beyond recovery and needs to be replaced.

Have you thought about doing the repair yourself?

Here’s a link to the ifixit Harman Kardon Onyx Studio 2 Battery Replacement guide. It details the necessary tools that are required and the procedure to gain access to the battery.

Here’s a link to the Harman Kardon Onyx Studio 2 Front Panel Replacement guide which shows how to remove it, before the battery removal procedure can be done.

Replacement batteries are available online.

Just search for Harman Kardon Onyx Studio 2 battery to get results for suppliers.

Here’s a link to a list of suppliers just to give you an idea of the cost of the battery. You may find there are other suppliers that suit you better.

The only thing to be aware of is that you reconnect the new battery the same way as the old battery was connected (in case the connector goes on both ways) so that the battery polarity is correct. Just check which side the red wire goes to or take pictures before you unplug the old battery to remind you. (pull out by gripping the plastic connector and not by the wires)

If you do decide to repair it yourself you’ll get a great sense of satisfaction afterwards, when it works. Just remember to take your time doing it and not to rush it. Keep a jar or container handy to put all the screws in so that you don’t lose any of them. Also remember to fully charge the new battery after the repair, before testing the speaker

Good luck with the repair ;-)
