everything back on, and determine whether the problem is in the same place: i.e., the speaker that was working previously
now has no sound and the speaker that was not working now sounds fine; or whether it has moved: i.e., the speaker that
was not working still has no sound and the speaker that was working is still fine. If the problem is in the same place, the
source of the problem is most likely with your receiver or amplifier, and you should consult the owner’s manual for that product
