Basic problem-solving with a CD player is similar to troubleshooting other electrical or electronic equipment.
Always check the most obvious possible causes first, such as the following examples:
Problem Probable Cause Remedy
No power when POWER
button is pressed
Power plug is not inserted Plug in securely fully into rear
socket
No playback when disc is
loaded, “NO DISC”
displayed
Disc is loaded with label side down
Incorrect disc type
Dirty disc
Moisture/humidity or cold affecting
laser lens
Re-load with label side up
Please load a standard audio CD
Clean disk and try again
Leave unit on for an hour to
allow moisture to evaporate.
No audio output, or too low
level output
Output muted
Volume set too low
Check mute is not on
Turn volume up
Sound is severely distorted,
and volume control needs to
be turned down very low
Line level audio lead is connected to
phono input sockets of the amplifier
Re-connect lead to auxiliary
sockets or other “line level”
amplifier input
Mis-tracking (sound jumping) Player is receiving vibration or shock
Disc is dirty
Moisture/humidity or cold affecting
laser lens
Change position of player away
from loudspeakers
Clean disc surface
Leave unit on for an hour to
allow moisture to evaporate.
Hum Audio connector plug is not fully pushed
in
Insert plug securely
Interference noise heard from
radio tuner
Player is positioned too near the tuner Keep a reasonable distance
between player and tuner, or
switch off player power
Player’s POWER switch is set to off Set switch to on
Battery(ies) fitted the wrong way round Insert batteries correctly
Batteries are flat Change batteries for a new set
Remote control does not
work
Remote control is not pointed directly
towards the front panel of the player
Ensure there is no obstruction
between the remote control and
player front
Remote control range has
greatly reduced
Batteries are running out Change batteries – for a new set
Remember - the most vulnerable part of a CD playing system is the disc itself. The most likely cause of a
disc not playing is that the disc itself is faulty, scratched or simply dirty. Never open the case of the unit
yourself, as this will invalidate the guarantee. If none of the above actions affect a cure, please contact your
dealer or Musical Fidelity service agent.
