If possible, it’s often good to try to isolate the problem first. For
example, if you’re playing a DVD on a television and there’s no
sound, try connecting an MP3 player to the system to see if that
works. If it does work, then the problem is with the television, DVD
player, or the cables connecting them. If it doesn’t work, the prob-
lem will be with the amplifier, speakers, or those cables.
Problem Possible Cause
No Sound
The volume may be turned down or muted. Check
the volume settings on both the amplifier and the
television/computer/CD player/etc.
Make sure the proper source is selected on the am-
plifier or receiver.
Check the cord connecting the amplifier with the
source. The cord may be damaged or plugged into
the wrong input or output.
Check the wires connecting the amplifier with the
speakers. Make sure they’re connected properly and
not damaged in any way.
Poor Sound Quality
If you hear something like static, or the sound is cut-
ting in and out, check the audio cables. If the prob-
lem increases when a cable is being moved, then the
cable is most likely faulty or not connected properly.
Today’s audio systems may have several places to
adjust the volume, for example your MP3 player may
have a volume control, and your amplifier may also
have one. Check to be certain that the volume isn’t
turned up past 80% on any device.
Try changing sources to be certain that the selection
you’ve chosen is a good quality recording.
