Question posted by sokrchase on July 8th, 2016

Sound Isn't Coming On.

When I turn my boss 752uab stereo on, no sound comes from any of the speakers. This just recently happened after it working for about two months with no problems. The stereo comes on with no problem, but for some reason no music comes from the speakers, not even static. I checked the wiring and all the connections are good. Any help
