Although cable breaks are one of the most common causes of sound failures, defective cables are amazingly often not recognized as a source of error. Defective cables, in particular, can be quickly replaced at home. Cable breaks can occur in speaker cables as well as in connection cables such as HDMI cables.
This is how easy it is to determine whether a cable, a speaker or amplifier is defective
If you suspect a cable break, box damage or amplifier defect, simply exchange the wiring to one box with the wiring on the other side as a test by deliberately connecting the connections on the receiver/amplifier the wrong way round (i.e. left box to right connection and vice versa) and then start any playback.
If the error (e.g. no sound or dropouts) now moves to the other side, there is most likely a defective cable. If the error remains on the same side despite replacing the cable, either the satellite/speaker may be defective or the amplifier output may have a defect.
Tip: You can determine whether the speaker or amplifier is defective in the same way if you have previously been able to rule out the possibility that the cable is defective.
