Philips CD 100 - Detailed Fault Diagnosis; Technical Data

2. After pressing PLAY, the disc does not begin to
turn.
— The player is not switched on.
— The disc is not properly located on the spindle.
— The disc compartment cover is not properly
closed.
~ There is an unwanted object in the disc com-
partment, e.g. a piece of paper or a remnant of
packaging.
3. The disc begins to turn, but stops after a few
seconds.
— The disc is not inserted with the label upwards.
— The disc is not flat. Try another disc which
appears flat, and see if that clears the fault.
— The disc is dirty. See if cleaning the disc, or using
another, clean disc, clears the fault.
4. The disc turns, but there is no sound.
~ The position of the (pre)amplifier source selec-
tor switch does not correspond with the input to
which the player is connected.
~— The (pre)amplifier is not switched on.
~— The (pre)amplifier or the (active) loudspeakers
connected to it are not working. Check with another
sound source to see if this is the case.
5. The sound is poor or distorted.
— The player is not connected to the CD/TV, AUX,
TUNER or TAPE IN input of the (pre)amplifier but to
the PHONO input.
~ The (pre)amplifier or the (active) loudspeakers
connected to it are not working properly. Check
with another sound source to see if this is the case.
— The disc is dirty or badly scratched. See if
cleaning the disc or using another, clean or
scratch-free, disc improves the situation.
— The laser pick-up lens may show signs of a film
of dirt. See if cleaning it with a cotton wool bud
improves the situation.
— There is an unwanted object in the disc com-
partment, e.g. a piece of paper or a remnant of
packaging.
— The transport screws have not been removed.
6. The ‘Add-in’ programme is not working properly.
-— The disc is dirty or badly scratched. See if
cleaning the disc helps or try programming a
scratch-free disc.
— All 15 memory entries have been used and you
have not noticed the flashing ERROR LED. Press
SELECT and STORE again to see if this is the case.
— You have tried to programme a higher track
number than exists on the disc. Check the number
of tracks on the disc title list.
7. The following four faults can be caused by the
same circumstances:
@ Playback does not begin within a few seconds of
pressing PLAY.
e@ After playback has begun, all 15 PROGR Dis-
play LEDs remain alight although there are fewer
tracks on the disc.
@ Playback does not begin with the first track on
the disc or the programme, but with another track.
@ Playback stops before the end of the disc or
programme is reached, the TRACK Display LED
flashes under the last played track number, the
PROGR Display LEDs for the tracks that have been
played also flash, and the remaining PROGR Dis-
play LEDs all light.
— The disc is dirty or badly scratched. See if
cleaning the disc or using another, clean or
scratch-free, disc clears the fault.
- The disc is not flat. Try another disc which
appears flat and see if that clears the fault.
— The laser pick-up lens shows signs of a film of
dirt. See if cleaning it with a cotton wool bud helps.
— There is an unwanted object in the disc com-
partment, e.g. a piece of paper or a remnant of
packaging.
