I had the very same issue so I got in contact with them and they arranged a repair - just had to pay for postage. It also stopped any sort of stand light.
The stand light on mine is also not working, but it was like that when i bought it second hand, thought that maybe these lights don't even have one. Will try to contact the supernova support then, it seems there is no easy fixes that i could do myself. thanks for the hint
