I bought a Klipsch Bar 48 with surround pack 3 weeks ago in Sydney from harvey Norman. At first the surround speakers volume would not increase. I have downloaded the latest firmware update V30 which helped somewhat but occasionally the surround speakers will have a burst of much louder sound than what they generate at full volume. I now notice that my subwoofer seems to have no power. I've tried it in several different power points but no light at all. Have tried unplugging soundbar and subwoofer power to restart but still no life in the subwoofer. Any suggestions would be greatly appreciated
