08.08 TYPENUMBERS : CDR570, CDR770, CDR771, CDR775, CDR776

SYMPTOM :

The set is switched to stand-by after power on.

CURE : The problem occurs only with the recently introduced new power

supply unit “PSU CDR3 ECONOMY”.
It can be fixed with the following modification:

• change item 3127 (current sense resistor) from 1.5Ω to 1Ω
(4822 116 80176)

• change item 6141 (zener diode) from 18V to 20V (4822 130 10656)

REMARKS : The above modification has been implemented in production from

week 0034 onwards.

08.09 TYPENUMBER(S): CDR785, CDR786, FW-R7, FW-R8

SYMPTOM :

Clock jitter in DASP-IC item 7701 on CDR Mainboard can result in
hang-up of the microprocessor.After Power off, Power on the set will
normally star t but the phenomenon might return again.

CURE : To solve this problem in running production and as service solution,

the power supply of D3V3 has been improved by adding a resistor of
27Ω (CRB 1/6W A PM5 and codenumber 4822 116 52188) between
“disconnected” pin 1 of item 7535 and ground (hole 2 of item 1701).

See part of the main board (top side view) for location of the resistor.

REMARKS : With release of the A9 version of CDR Mainboard this resistor is

implemented in printed board layout and mounted in production.

08.10 TYPENUMBER(S): CDR785, CDR786, FW-R7, FW-R8

SYMPTOM :

When source “AUX DIGITAL” is selected and no source is connected
or it is switched off, there is a burst of noise audible through the
speakers ever y 3 seconds. If a digital source is connected and
switched on, the noise disappears.

CURE : • change SMD resistor

3300 on Interface Board (CDR785, CDR786) resp.
3358 on Digital Switch Board (FW-R7, FW-R8)
to 6.8kΩ (4822 117 11507)

• add resistor 2721 (6.8kΩ 4822 117 11507) on the bottom side of
CDR Main Board → see picture below

REMARKS : This solution will also be implemented in production as a running

change.

FW-P78, FW-P88, FW-P880, FW-P900, FW-V55

SYMPTOM :

When a wireless heaphone (eg. SBC8320, SBCHC630, etc.) is
connected to the headphone socket, the headphone sound is
continuously interrupted.

CURE : The phenomenon is caused by a mis-match between the output

impedance of the heaphone amplifier (32Ω - 1kΩ) and the input
impedance of the wireless transmitter (10kΩ).
Due to the high input impedance of the transmitter the signal
becomes so high that the muting circuit is triggered.
The problem is solved by adding 2 resistors, 330Ω (4822 116 52219)
from the headphone switch pin 2 and 5 to common ground.

INFORMATION : Introduction of COMPAIR for CDR 3rd generation recorders

CDR570, CDR770, CDR775, CDR776, CDR785, CDR930, CDR950,
CDR951, FW-R7, FW-R8

With the new release COMPAIR 1.4 (ordernumber 4822 727 21637)
the existing COMPAIR Tool (star ter kit with order number
4822 727 21634) has been extended to be applied for the CDR 3rd
generation Recorders.With this tool the diagnosing of the set can be
done in an interactive way. In the tool also the adjustment procedure
has been implemented.This is absolutely necessary in case the
CDR-mainboard and/or (CDR-loader) CDM is disconnected from the
matched production combination.

For Author ised ser vice workshops which have installed COMPAIR 1.4
the following CDR-modules
3104 129 52511 for CDR570 and CDR930,
3104 129 52521 for CDR770,
3104 129 52530 for CDR775 and CDR776,
3104 129 52540 for CDR950 and CDR951,
3104 129 52580 for CDR785,
3104 129 52590 for FW-R7 and FW-R8
can be repaired on component level as explained in the Cologne
Training session (held in week 0019 and 0020).
In the Cologne Training we have explained the need of the interface
board to be used with COMPAIR.The codenumber for this board
reads 7104 086 91110, the connection cable to the module is
available with 3104 157 11120.
Based on the feedback from the Competence Centres a new simple
board will be introduced within a few weeks. The codenumber for this
board plus module connection cable reads 3122 785 90200.
Upgrading SW with the help of COMPAIR is not possible yet.

To have all modifications during production implemented on the CDR­mainboard the following actions have to be taken:

Software version 1.04 & 91.48:

It is advised to replace mainboards stamped A2 or A3 by at least
production stamp A7 and always adjust via COMPAIR.
For CDR570 and CDR930 the ordernumber for the CDR mainboard
reads 3104 128 05840.
For CDR770 the ordernumber reads 3104 128 05850.
Other models have never been produced with stamp A2 or A3.

Software version 1.23 & 91.63:

• Update to the latest SW version (see SNL2000.03.09)

• Replace capacitors 2725, 2726 and 2727 by 100nF 50V

INFORMATION : All returned discs, causing complaints on the CDR sets of the 3rd

generation, have been investigated. This results in the following
conclusion:

The Philips Megalife disc has been produced by Ricoh and Mitsui.
Most of the problems have been found with discs produced by Mitsui.

How to recognize the production centre?
Ricoh : made in USA printed on the jewel box

Mitsui : made in Europe printed on the jewel box.

Please note: Discs packed in a carton box (5pcs/carton) are

marked with made in USA!
Ricoh : Marked Audio HR100
Mitsui : Marked Audio100
Ricoh : serial number on inner circle consists of 4 character + 12

digits (e.g. ALXH 06109902214 3)
Mitsui : serial number on inner circle consists of 12 digits

(e.g. 9287 2217 4953)

It is not advised to apply the Mitsui disc in 3rd generation CDR
recorders up to software version 1.51.

05.07 TYPENUMBER(S): CDR785/17

SYMPTOM :

The Standby-LED is inoperative.
The power consumption in standby is higher than specified and close
to the power consumption is STOP-mode.

CURE : The problem is caused by the fishplate supporting the Power Supply

Unit. In some cases the fishplate can touch a copper track of the
Power Board close to resistor R204 (see picture below).

This will short-circuit par ts of the power supply circuitry to the ground
potential of the bottom frame.
As a result, the display will switch off, but the LED does not light.

Solution: Place an insulating layer (i.e. friction tape or piece of Fuller
board) between printed board and holder.

REMARKS : The green protection lacquer on the printed board normally ensures

proper insulation of copper tracks.However, due to transportation or
rough handling, the critical area can get exposed.

In production, the bottom frame has been modified.
The modified parts are used from week 0020.4 onwards.

SYMPTOM :

Skips tracks periodically or slide motor does not start-up at all.

CURE : In regions with high environmental pollution the problem might be

caused by erosion of the slide motor’s collector.
Erosion will permanently worsen the start-up behaviour of the slide
motor, up to an extent where the slide servo does not respond fast
enough to recover the track actuator from its outer position → tracks

will be skipped periodically.
Defective sets should be repaired as follows:

1. Replace CD-dr ive VAM2201 (4822 691 10772)

2. Increase the gain of the slide ser vo loop in order to increase the

start-up voltage at the slide motor (preventive action)

• Change resistor 3849 to 82kΩ 5% 1/6W (4822 116 52304)

• Change resistor 3850 to 5.6kΩ 5% 1/6W (4822 116 52289)

For this module a central repair procedure has been initiated.

The loader assembly, pos. 81 in the par tslist (9305 043 20901),
cannot be used for repair because the CDL4009 needs an extra
adjustment on the mainboard which cannot be carried out on first

SYMPTOM :

The cassette door will not open completely when a cassette is inside
the cassette compartment.

CURE : The capstan pin (pos. 41) of the tape mechanism will not disengage

fully from the cassette tape.The problem is caused by a combination
of the following:

a) Leaf springs (pos. 199) which are responsible to create a rotating

movement for the cassette during “door eject” are too weak to
push the cassette out of the capstan pin.

b) Mis-matched housing par ts of the cassette (see fig. 1) rub/scratch

against the support ribs of the cassette door (pos. 200).

c) Uneven cassette door support r ibs create an additional friction to

the rotating movement of the cassette.

X761IRIS CODE

6651IRIS CODE

Service Newsletter 2000 – Audio Systems 2/6

The problem is resolved by:

1) Cutting 2 ribs (both sides) on the cassette door in order to enable
a bigger rotational movement for the door during eject
(see figure 2 & 3).

2) Increasing the spring force on the cassette by pulling the spring in
the direction and up to the level shown in figure 3.

Caution: Ensure that the cassette is able to smoothly slide into the

cassette door before returning the set to the customer !

FW-C39

SYMPTOM :

A high frequency pitch (around 4kHz - 5kHz) is audible from the front
display panel in quiet environment.

CURE : The source of the noise comes from the filtering SMD capacitors

2418, 2420, 2476 and 2477.
The problem is resolved by adding 2 elcaps of 4,7µF
(4822 124 40769) in series across the existing SMDs capacitors of
the -F2 supply line.
The elcaps can by soldered onto the copperside of the Front board as
indicated in the circuit and SMD layout view below.

Rework procedure:

1) Dismantle the Cover CDC and Front assembly.

2) Prepare the 2 elcaps of 4,7µF (4822 124 40769) in ser ies.

3) Place an insulation tape onto the Front board (area under the
elcaps) to prevent the elcaps and their leads from short-circuiting
to the surrounding SMD components and pads.

4) Position the elcaps horizontally over the insulation tape and solder
them to the copper pads as shown.
Make sure that the elcaps are close to the Front board so that
there is no contact to the moving parts of the CDC module.

5) Re-assemble the Front assembly and Cover CDC.

SYMPTOM :

In DPL mode the volume increases spontaneously and turns back to
normal level later (especially at the center loudspeaker).

CURE : The problem is caused by insufficient current on the VOL_CLK

(DPL_V_CLK) line to drive pin 5 of the Volume IC 7712 M62429FP
on the AF board.

This is solved by changing resistor 3416 on the Front Board from
2,2kΩ to 680Ω (4822 117 10361).
