SYMPTOM

No sound on one channel

No sound on both channels

Hum from the speakers

POSSIBLE CAUSES AND TEST PROCEDURE

Short circuit or loose wire at the speaker or

amplifier terminals. Check that the connections are

secure and that there are no loose strands of wire

crossing from the positive to the negative terminals

at the back of the amplifier and /or the speaker.

Short circuit or a break in the speaker wire. Dis-

connect the speaker wire at both ends, separate the

2 conductors at both ends and test with a meter for

a short circuit. If there is no short, connect the two

conductors at one end and test with a meter for

continuity.

Speaker is not working. Connect the speaker to a

channel that plays another speaker.

Audio cable to input is bad. Connect another cable

that is known to be good.

Audio cable to the main inputs is bad. Connect

another cable that is known to be good.

Hum may be caused by a ground loop between

two of the other components in the system. To test

for another ground loop, try reversing the AC plugs

of each of the components in the system.
