I have a Bose AV28 media center with surround sound speaker system that has been working problem free for about 6 years. A few days ago, the system lost all sound. I can play a dvd on it and see the content on my tv, but there is no sound. The TV sound is hooked to the Bose, so while I can see all the channels, I get no sound. I have a Lifestyle 18 series III. when I switch it on, it says VCR, sound gets to 8/30 then stops, BOSE LIFESTYLE is on the display then switches off. Have tried to reset to no avail.
