wtraeholt Posted February 11, 2015 Share Posted February 11, 2015 When i turn on my amp today nothing came on except the four tone leds came on constant. (ABCD). No sound, nothing flashing, no lights on master volume, no bluetooth connection and can't do an update via usb. tried factory reset by pushing master volume and tone buttons together when turning the unit on. nothing seems to work.. help!!!
