I have a DM 115 powered speaker that has constant static and doesn't play any input signal. This speaker has had a background hiss for quite a while regardless of changing cords etc and has had less volume that the other matching speaker also. But it now only has static and doesn't seem play any signal. Same issue plugged into different power sources. Any suggestions on what components to look at. I opened it up but nothing was visually obvious. I have a video but not sure how to attach it said invalid file extension.
Thanks
