I've had L1 with 2 B1 and tone match for several years now set up and light showes white and red fans run all the time and top half of array does not work. Do I need to send it to be checked out or is it something I can fix.
Sadly this does sound like a fault. Please check your email as I have already sent you some ideas to check before we get the unit back.
All repairs can be handled either by your local L1 dealer, Millennium Music, Nottingham in your specific case or via Bose UK direct. For Bose UK please call 0870 741 4500 with the serial number of any faulty item.
