I am new to all of this. I have had my Bose LS 12 since 1998 so I am assuming it is a series 1. I tried to use it for the 1st time in several months the other day and I have no sound. I have checked all of my cables and such and all seem fine. I notice when i turn up the volume that there is no volume display. All of the other displays show such as AM-FM and the station, CD track, etc. I tried playing a CD and using the radio and still no sound. Could this be as simple as a fuse somewhere? Any ideas or thoughts would be greatly appreciated. PLEASE make it very clear and use step by step directions. I would need repair for dummies type of instructions. I dont think it would be worth to send it out for repair anymore so I would like to try to correct this on my own. THANKS in advance for any help!!!
