HT-5500 Subwoofer dead after 3 weeks any help/suggestion/reason?

I've speaking on behalf of a friend due to language barrier but apparently after using this HT-s5500 Setup for roughly 3 weeks...it died this past wednesday after he woke up to try and using it in the morning. Is it a dud or why isn't the subwoofer turning on and working anymore? Did it burn out or something? All settings are default. Everything else works great except the dead subwoofer.
