SYMPTOM :

The cassette doors (especially the left door) do not close properly.

CURE : The problem is most probably caused by:

• Tolerance in dimensions of door catches

• Deformation of plastic brackets of catches

In course of production the catch & plastic brackets have been modified.The service codenumbers for the new parts read as follows:

09.05 TYPENUMBER(S): FW538, FW850C, FW855C, FW860P, FW880P, FW880W

SYMPTOM :

During digital optical recordings from the above mentioned Mini Systems to a CD-Recorder (i.e. FW538 to CDR538), “DIG” flashes on the CDR, indicating a communication error. The problem usually occurs when recordings are started immediately after switching to an analog source (i.e.Tuner or Tape).

CURE : Customer is advised to follow the instructions for

CD-Recordings, given in Service Newsletter AS98.08.04.

REMARKS : When switching to an analog source, the Mini System will reset the

CD-part and mute the digital output signal for about 130ms. This mute is interpreted as communication error and causes a stop of the CD-Recording.

09.06 TYPENUMBER(S): FW670P

SYMPTOM :

In CD-mode the beginning part of each track is muted. The time constant for releasing the mute signal is too long.

CURE : Replace capacitor 2550 (2,2µF) on the Combi AF-part by a capacitor

of 1µF (4822 124 40242).

REMARKS :

09.07 TYPENUMBER(S): FW730C, FW750C, FW770P, FW780P, FW790P INFORMATION : The set does not read a specific CD:

“Ready to Go, Women of the 90’s” (74321 568712 BMG Ariola). This happens on versions with the CDC3-DH module only.

The problem can be solved by changing capacitor 2820 from 180pF to 330pF or adding a capacitor of 150pF in parallel to resistor 2820.

REMARKS : The CDC3-DH module can be identified by the printed board

codenumber “3104 113 3109”, located on both sides of the CDC3-board.

09.08 TYPENUMBER(S): MC135

SYMPTOM :

The set does not work at all.

CURE : One possibility of error is that leads of components on the Pre-amp

board are too long.When the PCB is bent due to mechanical tensions, the leads might touch the metal bracket and short-circuit certain par ts of the electronics.

Take care to cut the leads of replaced components as shor t as possible.

REMARKS : In course of production the lead cutting machine has been adjusted

for mininum lead-length, and a piece of rubber has been added between the Pre-amp board and the metal bracket.

INFORMATION : Due to delivery problems of the 4Mbit DRAM IC, the printed board of

the above mentioned sets had to be changed from “PB2” to “PB2+”. The major difference between these two boards is the number and

size of the DRAMs used:While PB2 is designed for two DRAMs (2x4Mbit max.), PB2+ can only handle one DRAM (1x16Mbit max.).

As a result the ESA buffer of sets with PB2+ will now store 43.2s of music (technical value).The commercial values of 12s for AZ738x resp.25s for AZ748x remain untouched.

PB2+ is alrady known from Mable Platform 5A – AZ7582, AZ7583. For servicing please refer to the following Service Manuals:

08.03 TYPENUMBER(S): CDR538, CDR560, CDR760, CDR765, FW538

SYMPTOM :

Howling occurs during analog recording from FW538 to one of the above mentioned CDRs when the user has accidentally switched the source of FW538 to AUX.

CURE : The problem is caused by a “closed loop” which is formed via

CDR line-out → FW538 AUX-IN → FW538 line out → CDR line-in. When the REC-level is adjusted to above a certain level howling occurs.This is the same phenomenon as known from recordings via microphone.

There is no other solution available as to advise the customer:

Do not select the AUX-mode on the FW538 during analog recording!

REMARKS : An addendum sheet will be added to the Instruction For Use.

08.05 TYPENUMBER(S): CDR538, CDR560, CDR760, CDR765 INFORMATION : When an external CD player or CD changer is in PAUSE function and

NEXT or PREVIOUS keys are pressed the CDR recorder can get in a recording function which records many tracks on a disc with a muted signal and all tracks are about 3 or 4 seconds long.

In case of recording from CD-changers: To avoid long pauses or a full recorded disc with silence the CD-recorders CDR765, CDR760, CDR560 and CDR538 have a 3 seconds auto stop mode built in. As CD changers most often need more than 3 seconds to start or switch over from one disc to another the muted input signal is recorded and automatically stopped.

To prevent this fault condition the recording has to be executed in the following way:

Recording one disc:

Start recording with the CD-sync function, digitally connected.

Recording a program over more than one disc:

Select the analog input with SOURCE and start recording manually by pushing RECORD & PLAY sequential on the CD-recorder. After that Start playing the CD-changer.

REMARKS :

08.06 TYPENUMBER(S): CDR765

SYMPTOM :

Shocksensitivity CD Player part

CURE : Under certain conditions it may occur that the CD-Player module is

very sensitive to shocks.This is very annoying in case of recording discs, because this hick-up will be recorded on the new disc. By using several separates composed to a tower it is advised to place the recorder on top of it. If this does not solve the problem the damping grommets of the CDM12.4 (items 42, 43, 44, 45 in the exploded view on page 5-3 of the Service Manual) have to be replaced by 4822 404 10987.

REMARKS : New damping gromments have been implemented in production from

week 9842 onwards.

CURE : Replacement of connector wires as given in Service Newsletter

AS97.03.02.

REMARKS : Reliability of EH-type connector was bad due to wrong material used

in the connector. 3 main actions were taken at the production centers from production week 9830 onwards:

1. Mater ial Phosphor Bronze is used for the connector

2. Split length of the wires has been increased from 20mm to 35mm in order to improve the flexibility of the wire

3. Training of operators on proper insertion and removal of connectors

INFORMATION : During production (around July 1998), elcap 2891 on the CD main

board has been changed from 10µF to 22µF (4822 124 81152). Reason: Avoid distorted sound during the initial 200 - 300 milliseconds after starting the disc.

Service Test Program – Service Play Test Due to the changed delay time, error codes like E1003 & E1011 might also be displayed on some good sets.This is caused by the test software which checks the status of the inner switch after certain milliseconds.

REMARKS : The Service Test Program will be adapted in the next software mask.

07.07 TYPENUMBER(S): FW355C

INFORMATION :

CD stops playing after some time due to a defective laser diode. The failure is most probably caused by ESD damage.

As preventive action additional ESD measures (storage, handling and packaging) have been implemented on the production floor in weeks 9813 to 9827.

In this special edition of the Service Newsletter Audio, instructions for lens cleaning and lubrication of various CD-drives are given.The drives have been spitted-up into two groups:

GROUP A : 4822 691 30278 CDM12.1

4822 691 30359 CDM12.3BL 4822 691 10487 CDM12.3BLC 4822 691 10615 VAM1201 4822 691 10665 VAM2103

4822 691 10535 CD93V4 4822 691 10654 CD94V5T1

WARNING !

PRINCIPLE: AVOID CLEANING THE LENS !

Cleaning the lens is not completely harmless. Only if the lens is obviously polluted with

fingerprints or soild, it can be cleaned with a cleaning solvent.

The objective lens of the CD-mechanism is an optical component that is exposed to the

environment. It is clear that the environment of a Juke-Box application is not comparable with

normal home use. Permanent dust, steam or nicotine from cigarette smoke will

(sooner or later) soil the lens and influence the playability of the system –

Cleaning of the lens becomes necessary.

Analysis of exchanged CD-drives has shown, that in a considerable quantity of drives the

malfunctions were caused by dirty lens. Before replacing a CD-drive it is therefore

recommended to clean the lens and check the functionality of the system again.

02.01 TYPENUMBER(S): GROUP A INFORMATION : Cleaning the objective lens

Before touching the lens it is advised to clean the surface of the lens by blowing clean air over it in order to avoid that little particles make scratches on the lens.

Because the material of the lens is synthetic and coated with a special anti-reflectivity layer, cleaning must be done with a nonaggressive cleaning fluid.It is advised to use lens cleaner “KODAK LENS CLEANER CAT 176 71 36”, available in normal photo shops.

The actuator is a very precise mechanical component and may not be damaged in order to guarantee its full function. It is advised to clean the lens gently (don’t press too hard) with a soft and clean cotton swab moistened with the special lens cleaner. The direction of cleaning must be in the way as indicated in the picture below.

REMARKS : See also newsletter issues 58.01 and 96.09.01.

02.02 TYPENUMBER(S): GROUP B INFORMATION : Cleaning the Objective lens

Cover a padstick with a piece of lens cleaning paper, i.e. “KODAK CAT 154 2067” or “DUSTER TK-3”. Put 2 to 3 drops of alcohol (99% or above) to the padstick. Rotate it slowly and gently on the surface of the lens.The solvent will dissolve fingerprints, grease etc... Finally the lens will be filled with the dirty cleaning solvent. Suck up the solvent with the edge of a piece of absorbing paper until the fluid has been removed.The remnants of the solvent will evaporate.

REMARKS : Never use cleaning solvents containing isopropanol!

02.03 TYPENUMBER(S): GROUP A INFORMATION : Cleaning and lubricating instructions

Lubrication of the CD-drive is needed in case of symptom “skipping tracks”.The reason can be dirt which sticks to the grease or the grease is getting aged.

Use grease “Tribol 9890-2” or equivalent. Before greasing the mechanism first remove the old grease from the

mechanism. Use a cotton swab dipped in alcohol to clean the mechanism.

Cleaning the mechanism

1. Clean the lower and upper sledge guidance plane (optical pick-up).

2. Clean the spindle shaft.

3. Clean the area between the wor m gear, idler wheel and clamping spring.

Lubricating the mechanism

1. Put onto the upper sledge guidance plane one dot of grease on each side of the sledge. Move the sledge to the inner and outer position to spread the grease. Put onto the lower sledge guidance plane one dot of grease on each side of the sledge. Move the sledge to the inner and outer position to spread the grease.

2. Put onto the spindle shaft one dot of grease on both sides of the sledge. Move the sledge to the inner and outer position to spread the grease.

3. Put one dot of grease between the worm gear and the clamping spring.

04.02 TYPENUMBER(S): CDR870 INFORMATION : The Recording Test disc

Problems concerning the recording facilities of the CDR870 can be checked by using a blank Digital Audio CD-ReWritable disc.This disc can be re-used afterwards and the CD-RW recording strategy does not deviate strong from the CD-R writing process.To define whether the set is working proper this disc can be read after recording and even after finalising. To ERASE complete disc use the ser vice test program and actuate simultaneously <ERASE> and <RECORD> keys together with <POWER ON>.This will take about 37 minutes because erasing is done at double disc speed.

REMARKS :

04.03 TYPENUMBER(S): CDR870 INFORMATION : CDR870 is not able to play CD R/W discs, recorded and finalised via

a computer.The CDR870 display shows “No Audio”. Explanation:

The audio bit, standing in the ATIP pregrove, is checked before starting up. In case of a final finalised CDR disc, the ATIP (Engine) is switched off. So the application can not reach this information anymore. In case of CD R/W, ATIP must always be active (to allow Erase DISC). So the audio bit will be detected by the application when starting up this disc. Because the audio bit is not detected in this case, the display shows the message "NO AUDIO". This is not an error but a too strong implementation of the law. In fact you may not record audio on a general purpose disc with a CDR870.

REMARKS : In the future reading audio from a general purpose disc will be

allowed. (CDR760 ....)

04.04 TYPENUMBER(S): CDR870

SYMPTOM :

Bad recording when using optical input of set

CURE : This problem is caused by the optical input device PLR102

(item 1520 on the connector PCB). In case the r isetime specification is worse than 50ns, the optical input signal may result in a bad recording.There are 2 solutions possible:

1. Replace PLR102 by TORX174 (Toshiba) with service codenumber 4822 130 91224. C2508 has to be replaced by a short circuit to ground.The risetime specifications of this device are <30ns.

2. Use one of the free inverter por ts of device 74HCU04N (item 7500) to improve the optical in signal.This can be done as follows:

• Connect output 4 of optical device to pin 9 of IC7500.

This pin must be lifted from the PCB.

• Connect pin 8 of IC7500 to pin 14 of connector 1500.

• Interrupt copper track between pin 14 of connector 1500 to pin 4

of switch 1522 (not mounted). With this solution, steep flanks will be created on the signal. Note that inverting is no problem for a biphase signal. See also picture of the modified PCB below.

REMARKS : An improved connector PCB will be introduced in course of

production. See Ser vice Information A98-250 (4822 725 25244).

EACEM IRIS is an INTERNATIONAL REPAIR INFORMATION SYSTEM of the EUROPEAN ASSOCIATION OF CONSUMER ELECTRONICS MANUFACTURERS.

The system was developed by several companies and had been evolving for many years in different countries in different variations before it was finally standardized by the EACEM IRIS committee in May 1995. EACEM IRIS is kept up to date and reviewed periodically. New innovations and new product categories lead to the current revision 02, finalized in September 1997.

EACEM IRIS CODING

The “heart” of EACEM IRIS is a standardized coding structure. The full IRIS coding system consists of a set of five codes:

• The CONDITION CODE (under which condition does the defect occur)

• The SYMPTOM CODE (what was the symptom perceived by the user)

• The SECTION CODE (where was the defect located)

• The DEFECT CODE (which part and type of defect).

• The REPAIR CODE (what action was taken to correct the problem). Example of use:

Tables on next pages give a survey of available codes in EACEM IRIS.

Note that IRIS codes, published in Service Newsletters,

are only related to the Condition/Symptom codeset.

LINE OF BUSINESS AUDIO SYSTEMS

03.01 TYPENUMBER(S): ALL TYPENUMBERS

SYMPTOM : POS stickers on cassette doors & loudspeaker boxes cannot be

removed.

CURE : The stain-mark left behind from POS stickers can be removed by any

cleaning fluid that does not attack plastic surfaces. One effective remover is the “Contact Cleaner Spray”, available in most service workshops. The spray can be ordered with service codenumber 4822 389 50091.

REMARKS :

03.02 TYPENUMBER(S): AS660C, AS665C, FW332, FW335, FW340C, FW342C, FW345C,

FW352C, FW362, FW363, FW372C, FW373C, FW710C, MC130, MC150

INFORMATION : Correction Service Manual, partslist:

The service codenumber for the loudspeaker socket (pos. 1290) on the Power Board is missing.The socket can be ordered with 4822 265 10967.

REMARKS :

03.03 TYPENUMBER(S): FW36, FW56, FW360C, FW650C SYMPTOM : The 7-disc changer is jamming. CURE : The problem is caused by poor engagement between the worm gear

of motor (pos. 30) and gear H (pos. 33) due to alignment between the 2 parts. The alignment is improved by modifying the metal bracket (pos. 31) for the motor. The improved metal bracket is now available with service codenumber 4822 466 11893.

REMARKS : See also Service Newsletter AS98.01.04.

03.04 TYPENUMBER(S): FW332 SYMPTOM : Cassette door jams with cassette inside during eject CURE : The problem is caused by deformation of the cassette door’s plastic

springs. For repair the cassette door must be replaced by an improved

cassette door.Improved cassette doors can be recognized by a step at the bottom edge of the door (see picture).

REMARKS : Improved cassette doors have been implemented in production from

week 9802 onwards (sets with serial no. MA....).
