SOUND ONLY COMES FROM ONE OF THE TWO SPEAKERS

Check speaker harness connections on the back of the display board. Swap the left and right
connections. If the same speaker doesn't play, the speaker is bad. If the other speaker doesn't
play, the display board is bad.
MUSIC DOESN'T SEEM TO PLAY AT ALL.
-The display will show "CDERR" if it cannot communicate with the changer. If you see that error,
try to eject the CD cartridge. If it does not eject, check and reset the changer harness connections.
If the harness looks good, the most likely part to replace is the changer itself. If that doesn't work,
replace the display board.
-Turn the volume knob clockwise, volumes below 8-12 may be inaudible depending on ambient
noise.
-Turn the CD/TRACK knob to see if its possible to change tracks. If you can change tracks but no
music plays, the display board audio amp may be blown so replace the display board.
-If the display shows "–LOAD" after you turn the CD/TRACK knob, it is still looking for a CD. It
searches the cartridge in order from slot 1 to slot 6, so if you only have a CD in slot 6, it will take a
while to get there before it begins to play.
-Try another CD, this one may be scratched.
-Some, but not all CD copies (CDR, CDRW) will play in the changer. If a copied CD is not playing,
try an original CD.
