If there is no sound from any of the speakers:
•Check that receiver/ampli- fier is on and a source is playing.
•Check all wires and con- nections between receiver/ amplifier and speakers. Make sure all wires are con- nected. Make sure none of the speaker wires are frayed, cut or punctured, or touching each other.

•Turn off all electronics
and switch the speaker in question with one of the other speakers that is work- ing correctly. Turn every- thing back on, and deter- mine whether the problem has followed the speaker, or has remained in the same channel. If the problem is in the same channel, the source of the problem
