First, make sure you have fresh batteries and try redoing the firmware. Try to turn the lights on.
If it doesn't work. You'll have to pay to get it fixed because you are out of your warranty. (90 days) And I wouldn't advise opening the controller If I were you either. You could screw it up because it's very complex. PM Odingalt/Fredrow/Ben
(Ben's in the UK , Fredrow is in Seattle, and Odin, is somewhere, no clue where though.)
EDIT: I also heard that Modded Matt does repairs/mods so ask him if you wish.
