So the when I turn the '''''Volume knob''''' up to increase the Volume it just goes down to negatives(ex….-1,-2,-3etc..)and I cannot get it past the 0 to raise it just goes into the negatives. The knob spins all the way around when it suppose to go up to 12oclock(+) and down to 6oclock (-) . I took it off try to push it in but cannot figure… Does anyone know how I can fix it??
