Apogee Duet 2 - LEDS don't work

I have the above and recently the lights and meters on the front of the unit have stopped working.

The unit still works and with Logic however. It still functions but its trickier to use without the lights. Yes I can use the software on the mac to monitor levels but its more of a pain to switch to inputs, headphoes etc.

Any other people with the same problem?

Anyone with the answer? I'd be so grateful.

Thanks
