Headphone Monitor problem with my HUI

I'm only getting sound out of the left side of my HUI headphone output. Any ideas? I've tried different headphones, swapped cables on the input, swapped the input, Used a different source, I'm not in "discrete" mode. I'm thinking it's the jack, but maybe I'm missing something simple and obvious? Anyone else experience this? Thanks! Karen

Anyone, anyone?

Thanks RCM, How difficult (or easy) is it to get at the monitor jack(s) to fix them? Maybe it's an easy fix that I can do myself? I've soldered many a cable before. Thanks for the tips! Karen

Well, it's more tedious than difficult... You have to remove the bottom cover (lots of screws), and then you can access the circuit board that has all the jacks attached to it. The biggest chore is removing all the nuts that hold the jacks to the back of the HUI. Seems you have to unhook a couple of ribbon cables, and kind of angle out the assembly. On mine I had a lot of cold-solder joints on the circuit board where the jacks were mounted. Pretty intuitive if you've done that kind of repair before, but I'd budget a couple of hours for it. Of course there's no way to test it without reassembly, so it could just as easily be a waste of time if you have bad components. Didn't seem there was much in the way of user replaceable parts on the circuit board, unless you have a bad jack itself. Might be worth a try if you have some spare time. rcm
