Troubleshooting the German Wurlitzers CDM3, CDM4, CDM12, & CD-PRO

1) If your German Wurlitzer CD jukebox is between serial numbers 3106XXXX and 3207XXXX
(June 1991 - July 1992) and you have any of the following problems, then you probably need to
read this PDF.
(German/English/French) Symptom 1) SCC Control Unit faulty    
    1. Record carrier turns continuously (and the "Z" - CD Count & "K" - Carriage Home LEDs are flashing
correctly on the SC&C).
    2. Gripper arm moves continuously, putting the CD on the player and returning it immediately.
    3. A selected CD is put on the player, is not played however, and returned to the record carrier after 15 sec (SC&C 40315).
    4. A selected CD is placed on the player, the TOC (Table Of Contents red LED under CD-Control keypad
goes out)) is read in but the selected CD is not being played (SC&C 40315).

or Symptom 2) Opto-Coupler interface in CD Control faulty (in combination with SC&C 40315)
    1. A selected CD is put on the player. The CD turns continuously fast clockwise or anti-clockwise; no sound
appears and after approx. 50 sec. it is returned to the record carrier.
    2. A selected CD is placed on the player, SC&C control tries 3 times to read the TOC (relay M6 clicks 7 times).
CD is then returned to the record carrier.

or Symptom 3) EMP faulty (only in models with EMP MMS 111) - Electronic Coin Mechanism(we sold none in Canada)
    1. The display indicates credit without coin insertion.


2) CD-Jukebox tosses CDs:
On CDM3, CDM4, and CDM12 models (converted from earlier players) up to serial number 3209xxxx the machine
stores the CD Clamp Arm with the magnet clasped to the CD player. This unfortunately leads to premature breakage
of the magnetic puck rim and it will sit unevenly on the CD Clamp leading to poor securing of CDs and subsequent
tossing of CDs. It looks like simply adjusting the Clamp Arm Height (rear) will enable the Clamp Arm to sit above
the player when at rest
, saving the puck. I do suspect that the newer Clamp Arm Lift assemby is also required. Picture
of new and old puck and where they are!


3) Infra-Red Remote seems to have intermittant problems:
IR Remotes can be confused by some types of "Compact" flourescent bulbs. So if your jukebox is behaving oddly
try turning off any compact flourescent bulbs in the same room and see if the problem goes away...

4) CDM-12 and early CD-Pro - CD won't center properly on player. Philips originally used a 'Spider' type of
centering disc that was prone to breakage of the tiny fingers. This was replaced with a solid cone. Recommended
update!
Cone is $10 plus postage...

 TROUBLE SHOOTING CHART CDM3 and CDM4S CD-Player models (edited text below)

CONTENTS
CHAPTER I.   Failures with the illumination, display and power system generally.
             1. Symptoms: No light, phonograph not working at all.
                          Blown primary fuse, defective power switch, or problem with
                          line cord (damaged cord or plug).
	     2. Symptoms: Illumination does not light. Phonograph otherwise works.
	     3. Symptoms: Bubble tubes do not work, colour tubes do not rotate, lamp
	                  24V does not light.
	     4. Symptoms: Digital display remains dark, phonograph otherwise works.
	     5. Symptoms: Digital display shows non-sense figures; phonograph otherwise works.
	     6. Symptoms: Digital display shows incomplete figures (missing segment).
	                  The fault is the same with all four digits.
        7. Symptoms: Digital display shows incomplete figures (missing segment).
                     The fault, however, occurs with one (or up to three) of the
                     four digits of display completely off.
	     8. Symptoms: One of the digits of display completely off.
        9. Symptoms: Digital display shows "4" and machine is unresponsive to key-pad. 
        10. Symptoms: Display shows "8" Check for correct operation of Microswitch K7 


CHAPTER II: Fuses. Which one controls what circuit?
CHAPTER III: Faults with the coin system. The Phonograph, however, operates normally with free credit established with the jumper in the column GP at SCC unit (0-F).The function of the coin system can be checked by observing the LED-light "M" at the Selection & Credit Computer- this should be off normally.
1. Symptoms: Coins rejected as bad ones. 2. Symptoms: Wrong credits (or none) with one type of coin. 3. Symptoms: Permanent credit, display shows 0001 permanently, free selections. 4. Symptoms: Wrong credits, repetitive or all the time, with credits higher or lower than programmed pricing. 5. Symptoms: No credit, coins are properly accepted. Free Play, with GP- jumper 0-F still possible. 6. Symptoms: No credit although coins are registered (LED-M lights up). No free play credits even with GP jumper set 0 to F. 7. Symptoms: No credit, LED - M lights permanently.
If the "M" LED is is always on then try unplugging the inputs to the right starting with 1, then 2, then 4, then ... until the "M" LED goes out. This will indicate the problem area. Here is the coin acceptor release, next tip it out, then check that the coin switch paddles are all horizontal. The coin acceptor can have junk in it that jams a coin paddle down - this will result in the "M" LED being constantly lit and the jukebox to ignore coins.
CHAPTER IV: Faults by selection entry (credit system does work).
1. Symptoms: No selections possible, digital display blinks with given selection keys are disabled. 2. Symptoms: No selections; numbers of actuated keys not displayed (only credit is shown). 3. Symptoms: No selections. In standby the LH digit of display shows a number, but selection keys are disabled. With insertion of further coins the new credit is displayed properly. 4. Symptoms: No response from one key (or some). 5. Symptoms: The CD played is not the one selected. The selection was properly displayed, the according track plays, too. 6. Symptoms: After power up a track or more are played without a selection. 7. Symptoms: The CD played is the one selected, however, not the selected track. 8. Symptoms: The selected CD will not be played, the CD carrier is rotating permanently. 9. Symptoms: The selected CD is placed on the turntable, but it is not playing. Turntable motor is not moving on. TOC-LED is not lighting. Wurlitzer Service Module if connected is dark. After six picks of M6 the CD is returned to carrier. Caution! Fault 5 10. Symptoms: The selected CD is placed on turntable, but not played. Turntable motor is moving on. TOC-LED lights and goes dark after motor start (correct characteristics). However after this the SCC unit transmits no track number (rc5-signal). The digi 11. Symptoms: The selected CD is placed on turntable, but not played. Turntable motor moves not on. TOC-LED lights but doesn't go dark after motor start. Wurlitzer Service Module if connected lights, TRAY OUT-LED changes its state after every pick of relay M6. After every attempt of TOC reading the third point from display left side lights for a short time. After 7 picks of relay M6 the CD moves back to carrier. 12. Symptoms: The selected CD is placed on the turntable, but only after 7 picks of relay M6 the digital display starts to flash (shows the transmitting procedure of track number) and the selected track is played. At a connected Wurlitzer Service Module 13. Symptoms: The selected CD is placed on the turntable, motor moves on two times for a short time then the track number will be transmitted (digital display flashes). After a new attempt of play the CD is took back into carrier after about 30 seconds. 14. Symptoms: The selected CD is placed on the turntable and moves on for four short times. Successful TOC reading procedure can watched at the TOC-LED or if connected at the Wurlitzer Service Module. After this the track (rc5 signal) is transmitted to CD-Control 15. Symptoms: The selected CD is placed on the turntable and moves on for one time but after approximately 35 seconds it will be returned into carrier. The correct TOC read procedure and the transmit of the track number (rc5 signal) are watchable with the TO 16. Symptoms: The selected CD is placed on the turntable and moves on for three short times after this it will returned into carrier. CD is playable with the buttons 6 and 9 in service level one (and also with the test buttons at CD control unit). At this t 17. Symptoms: CD is only playing after the fifth turntable motor start. The service level 1 shows "11 " at the digital display. CD play is accessible with the buttons 6 and 9 in the service program level 1. 18. Symptoms: CD play is suddenly interrupted, by turntable motor suddenly moving backward very fast or it is permanently moving backward. 19. Symptoms: The selection will be accepted, displayed but after this the phonograph doesn't do anything. 20. Symptoms: After Power up the first selection is played normally but then the phonograph takes no notice of any input. Only after a next power up the phonograph one CD again.

CHAPTER V: Repetitive apply of selected or non-selected discs to turntable.
1. Symptoms: Permanent gripper arm movement (with disc or none) with the disc carrier is not making a rotation between a complete cycle. This continues even if plug blue is disconnected at the SCC unit. 2. Symptoms: Permanent gripper arm movement; discontinued after plug BLUE is pulled off at the SCC unit.

CHAPTER Vl: Failures of the record changer after a properly completed selection. 1. Symptoms: Record carrier permanently rotating, even after plug BLUE is pulled. If a selection is made the gripper arm randomly takes a disc on turntable. 2. Symptoms: Record carrier permanently rotating. Sometimes the gripper arm randomly takes a disc on turntable, but the CD will not be played. Also by pressing the LT button the gripper arm takes a CD on turntable, the CD will not be played, too. After p 8 3. Symptoms: Carrier does not start after a properly completed selection. Carrier latch does not open. 4. Symptoms: Disc carrier does not rotate although the carrier latch opens after a selection. 5. Symptoms: Gripper arm does not move to take the disc out of the carrier although the selected disc was properly brought forward. After approx. 1 second relay M drops out. The phonograph does not work and takes no notice of any input. 6. Symptoms: Disc on turntable returned to carrier before play has started.

Chapter VII: Failures with sound reproduction. 1. Symptoms: Clicks and bang noises during CD playing, jump over of traces. 2. Symptoms: CD moves on but no sound. 3. Symptoms: Strong noise in one or both channels. 4. Symptoms: Box plays with full loudness, loudness is not regulateable. CHAPTER VIII: CD not properly returned to carrier. 1. Symptoms: Gripper arm does not move to bring the disc home. 2. Symptoms: Returned disc not properly unclasped (not freed) in the carrier. 3. Symptoms: Disc missing in compartment is found in other compartment or somewhere about the chassis.
4. Volume levels change when playing a record. Check the following: Take a look at the cartridge on the tone arm - perhaps it is loose on its mount and
this could cause sound fluctuations. Also check that the stylus.needle is firmly held by the
cartridge and not loose or falling out. Lastly check the wires on the end of the cartridge - are
they making good connection, are the four cartridge pins grabbed securely? If all that is good, then try this next - on the volume control box there is a switch - if slid
to one side then the left volume control adjusts both channels together (the right volume control
does nothing), if slide the other way then each volume control adjusts only one channel. Now turn
the right volume control up to a comfortable level and listen for fluctuations. If OK, then turn
right side down and try just the left volume. Any difference? I am assuming that the records sit flat on the turntable and the rubber ring driving the turntable
is good...Check AVC.

CHAPTER X: Hints to the test program of the Philips Control Board (CDM-3 and CDM-4 series)


Lubrication

We recommend that you oil/grease your Deutsche Wurlitzer jukebox every two years to prolong it's work life. We use high
pressure grease on the gears, and "Zoom-Spout" oil for the motors and pivots.
  
Lubrication Chart for CD and 45RPM/Vinyl Jukeboxes
Lube-colour-cylinder-motors.JPG (302713 bytes) A drop or two on the spindle of the two colour cylinder motors Lube-rear-of-pages-motor.JPG (306159 bytes) A drop of oil on the tail end of the title page motor
Lube-Grease-Gears.JPG (306249 bytes) Greased gears (a bit too much, wipe the excess off!) Lube-Gripper-bushing.JPG (314492 bytes) Oil the gripper arm drive shaft bushing at the gear box
Lube-Gripper-OuterSupport.JPG (313945 bytes) Oil the support end of the gripper arm drive shaft Lube-Oil-Gearbox-pivots.JPG (286501 bytes) Take the gear box cover off and oil the record clamp release drive shaft linkages - also oil the (unshown) pivot of the lift assembly for the record/CD clamp arm.
Lube-Oil-Gripper-gear-assembly.JPG (119773 bytes) These are CRITICAL - oil the pivots for the segment gear that drives the gripper arm drive shaft! (details on picture) Lube-oli-Gripper-gear-assembly-pivot.JPG (111320 bytes) This oil spot is awkward, it is the bottom left corner of the rectangular notch beside microswitch K7 - this is the front of the pivot for the segment gear
Lube-Carosel-motor.JPG (309095 bytes) A couple of drops of oil on the drive shaft for the carousel motor (take a look at the black drive tire and replace if required) Lube-Carosel-spindle.JPG (300105 bytes) A drop of oil on the centre spindle of the carousel.
Lube-Carosel-latch.JPG (301993 bytes) Two drops (one per half) on the latch on the front right of the carousel Lube-CD-Clamp-pivots.JPG (309546 bytes) Oil the pivots for the record/CD clamp flap
Lube-CD-Clamp-lift-rod.JPG (305195 bytes) Oil the centre lift rod for the record/CD clamp flap. A drop of oil on your 45 tone arm pivot - symptom is the tone arm bounces across record, or starts later than usual on the record.
Another drop here... Take underneath black cover off to expose this oil spot...
And this. Lastly, a drop of oil on the motor spindle - you might want to raise the pulley to get at it as you do not want oil on the pulley!
