Zoom H4n headphone out issue

[PhantomBox]

Hi.

I received a ZOOM H4n Audio Recorder for repair.

The headphone / line output jack didn't work, probably because of corrosion, so I cleaned it with a toothpick and some alcohol but this didn't solve the problem completely.

When I plug a stereo headphone into the device, I can only hear one side of the headphones. Should I clean the jack again? Or is it just a matter of configuration?

I'm asking this stupid question because I really hate the Idea of taking the ZOOM apart.

Thanks for you advise.

You may have to pull that thing apart if toothpick approach didn't work... look for a cold solder joints. I'd replace the whole socket.

Good luck,
Nick

Do you by any chance know the part number or where to locate one? Or at least how many contacts this socket has? There seems to be 2 switches inside it. I could find 6 contacts in total: 1 for ground, 3 more for the switch on one channel but only 2 for the switch on the second one.
