Brand New Replacement CD-PRO 2 CD Player for Wurlitzer, NSM or ROWE
Unfortunately the upgrade kit (instructions) to replace your defective CDM3 or CDM4S, with a CD-Pro series player is no longer available.
Identify your player with this PDF.
Troubleshooting the German Wurlitzers CDM3, CDM4-I, CDM12, & CD-PRO (pictures of the various CD-players)
Mechanism Service Adjustment documents - these are from the 1986/87 service manual (A4 European size, you will need to reduce them to Letter Size) but cover the OMT series as well - both vinyl and CD: In German, English, and French. These cover adjusting the gripper arm, gearbox, tone arm, carousel, and record player. Very handy! A better copy of the Service Manual is available - email us!
Tips & Techniques:
1) Your CDM-3 CD jukebox is not playing CDs (loads CD, spins a couple of times or after about twenty seconds simply returns the CD to the carousel) - check the Thermister under the metal cover just to the left of the Selection & Credit computer. I recommend replacing the Thermister with a 3A (max) fast blow fuse (pigtail leads as it must be soldered in)
2) 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.
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.
3) OMT-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 assembly is also required. Picture
of new and old puck and where they are!
3a) OMT-45 or OMT-CD Jukebox tosses records:
Another problem is when either the oils and grease have dried up causing the gripper arm to be sluggish in operation,
or the gripper claw is cracked or has a problem. Here is a short video showing the proper speed of the gripper arm cycle.
3b) OMT-45 or -CD takes too long to cycle and you get an error number:
Here is a short video showing the proper speed of the gripper arm cycle. When the gripper arm motor is too slow it can be either
lubrication or a fouled up armature inside the motor itself. Here are some pictures on fixing the armature by cleaning the gaps with
a thin metal strip (or plastic) that fits snuggly in the slots of the armature. Cleaning these will bring the motor back to factory
4) Infra-Red Remote seems to have intermittent problems:
IR Remotes can be confused by some types of "Compact" fluorescent bulbs. So if your jukebox is behaving oddly
try turning off any compact fluorescent bulbs in the same room and see if the problem goes away...
5) CDM-12 and early CD-Pro - CD won't centre properly on player. Philips originally used a 'Spider' type of
centring disc that was prone to breakage of the tiny fingers. This was replaced with a solid cone. Recommended update! Cone is $10 plus postage...
6) CDM-12 & CD-Pro - testing the player PDF from field service manual outlining how to check the player when either on the bench of in the machine while the machine is idle. You will need a magnetic puck to keep the CD in place. If you are testing the player in the machine you will need to go to self test to clamp a CD.
7) Record or CD basket/carousel turns endlessly - check that the Index Light (located under the black cover) is lit, if lit, then check that the Z and K LEDs on the Selection & Credit Computer are flashing as follows: K LED flashes once per revolution (home), Z LED flashes continuously (once per CD/45). Theory of K&Z LED operation PDF. You can order the bulb from us here. Youtube video of how to replace light bulb
7a) Display shows constant alternating Zeros - '0' - '0' - '0' back and forth, and the carousel basket is either turning or it is not:
The alternating zeros are displayed because the SCC thinks the carrier is rotating (whether it actually is or not, it’s just for show purposes). My best diagnosis would be that the relay for the latch solenoid is pulled in, but either not making contact or there is an interruption between there and the latch solenoid (which includes the K7 switch), but the flashing 8 is not present to indicate a defective K7 switch/actuator. Best troubleshooting method:
Unplug plug blue from SCC
Using a pricing jumper wire (white wire with pin soldered on each end) short from Green to Blue…gripper motor should run and stop at either end if jumper is removed; no motor operation check motor, motor switch, +30v
If OK, cycle motor to home position over basket …
Using a pricing jumper short from Green to Gray…Latch solenoid should operate, carrier should rotate, Z should flash; if not check latch solenoid, K7 switch, K8 switch (if latch operates, but motor doesn’t), and -30v source.
If the above tests are OK, replace SCC (computer).
8) Flashing '8', nothing else is happening:This is usually a defective K7 switch or the actuator (part number 10900) has become loose or cracked and no longer stays adjusted. See this page for details...
9) Machine is set to Free Play, but nothing happens (Safety Switch/Microswitch K8 not activated) - display shows
normal digits when entered:
On North American Wurlitzers (made in USA - 45RPM) this problem is often caused by someone grabbing the Gripper Bow (the part that picks up the 45s only) and lifts it high enough that the Record Clamp disengages from the Lever that holds the
Record Clamp pin against the Safety Switch (Microswitch K8 on the German models). With the Safety Switch(K8) disengaged the machine will sit forever.
Cure: Lift gripper bow up so that the Record Clamp pin clears the Lever, then push the Lever towards the Magazine enough so that when you let the Gripper Bow back down the pin is engaged,and the plastic pin on the Record Clamp pushes against the lever for the Safety Switch (Microswitch K8).
For German made jukeboxes, make sure the Lever moves freely and quickly, if it is slow/gummed up, then K8 may not activate.
These pictures are from a record (45RPM) version of the German OMT but the CD version is almost identical.
9) Testing if the CD player LASER is working using a digital camera...
I find you can use a standard digital camera (I used a Nikon Coolpix for this test) and you are able to see on the camera view screen if the laser is lighting up.
DO NOT ATTEMPT TO LOOK DIRECTLY AT THE LASER LENS AS IT MAY DAMAGE YOUR EYE(S)!
Make a selection (no CD to be played) and then aim the camera over the lens just off angle slightly and you should see a white light in the middle of the lens flashing slowly (MP4 video clip) on/off/on a few times while it hunts for the (non-existent) CD. No light? Check power to player, etc. The picutre on the left shows the laser glowing, the picture on the right shows the laser lighting up a thin peice of paper laid over the lens (click on images for bigger pictures).
TROUBLE SHOOTING CHART for CDM3 and CDM4S CD-Player models (edited text below)
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.
4a. Symptoms: Bubble tubes & lights work, carousel not rotating, display remains
dark - Check RESET capacitor 22 (220/16V) is not shorted.
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
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
7. Symptoms: The CD played is the one selected, however, not the
8. Symptoms: The selected CD will not be played, the CD carrier is rotating
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!
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).
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
18. Symptoms: CD play is suddenly interrupted, by turntable motor suddenly
moving backward very fast or it is permanently moving
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
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
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
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
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 IX: Hints for trouble shooting
CHAPTER X: Hints to the test program of the Philips Control Board (CDM-3 and CDM-4 series)
Early OMTs heater connection to the transformer...
Bubble tubes and colour cylinder motor fuses are here - moounted on the inside of the main front door just below speakers:
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
||A drop or two on the spindle of the two colour cylinder motors
||A drop of oil on the tail end of the title page motor
||Greased gears (a bit too much, wipe the excess off!)
||Oil the gripper arm drive shaft bushing at the gear box
||Oil the support end of the gripper arm drive shaft
||Take the gear box cover off and oil the record clamp release drive shaft linkages - also oil the (not shown) pivot of the lift assembly for the record/CD clamp arm.
||These are CRITICAL - oil the pivots for the segment gear that drives the gripper arm drive shaft! (details on picture)
||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
||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)
||A drop of oil on the centre spindle of the carousel.
||Two drops (one per half) on the latch on the front right of the carousel
||Oil the pivots for the record/CD clamp flap
||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...
||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!
