INFORMATION : Summary of hardware and software modifications to the CDR

Main Board.

In the following tables there is given reference to “main board labelled
with change code”.This label can be found on top at the front side of
the main board.

When “AA” is printed (as shown in picture above) this means that the
main board has once been upgraded before assembling in the set.
In this case the status has to be determined by reading out the
software versions via service testprogram - the procedure is
described in the service manual of the relevant set - or can be found
on a sticker on Flash ROM 7208.
Note: A clear determination of the status can best be given by

reading out the software versions!

“Y” means that software has to be/can be upgraded

or mentioned hardware change has to be done.
Empty fields mean that changes are already implemented in boards
with corresponding label.

double deck sets) → uniform software for all applications

REMARKS :

01.10 TYPENUMBER(S): CDR570, CDR770, CDR775, CDR930, CDR950

SYMPTOM :

Not reading/recording of Non-Philips branded CDR-discs respectively
Philips Megalife disc produced by Mitsui.
(for details concerning the MITSUI-discs see information in
SNL2000.07.14 respectively point 01.14 in this Service Newsletter)

CURE : The problem can be solved by applying the modifications as

mentioned in SNL2000.07.08 and with an update to the latest
software versions.The hardware modification which has to be
executed depends on the original SW version. Details are also given
in the

Summary of hardware and software modifications to the CDR

Main Board

, published with point 01.09 in this Service Newsletter.

• The Flash ROM software version of item 7208 (MACE) on the top
side (in socket) has been changed into version 92.11. Programmed
Flash ROM with SW-version 92.11 or higher can be ordered with
codenumber 3104 123 94850.

• The Flash ROM software version of item 7703 (DASP) on the top
side has been changed into version 1.56. Programmed Flash ROM
with SW-version 1.56 or higher can be ordered with codenumber
3104 123 85760.

REMARKS : After the update of both Flash ROMs, the module has to be re-

aligned with the improved COMPAIR-tool (release 1.6 or higher).
The CDR-alignment includes now beta adjustment via Test Disc 99
(TD99). After this modification and alignment all Digital Audio CDR­discs can be applied (no longer restricted to only Philips brand).Test
Disc 99 is available with codenumber 7104 099 93132.

01.11 TYPENUMBER(S): CDR570, CDR770, CDR775, CDR930, CDR950, CDR951

SYMPTOM :

After switching on the set, the standby-LED will start blinking and the

display does not light up.
CURE : Delete item 2546 (Elcap 47µF 6,3V) on the mainboard.
REMARKS : The modification has been implemented in production from week

0048 onwards.

01.12 TYPENUMBER(S): CDR570, CDR770, CDR930
INFORMATION : When customers complain that the Remote Control does not work

this does not necessarily mean that it is defective.More often the
customer has simply selected the wrong source on the RC.
Especially sets with single CDR loader will not react at all when “CD”
has been pressed on the RC.
Therefore the customer has to be advised as follows:

1) Select the right source first → Press <CDR> button and tr y again.

2) Point the Remote Control directly to the CD recorder.

3) Check the batteries and replace if necessary.

REMARKS :

01.13 TYPENUMBER(S): CDR770, CDR771, CDR775
INFORMATION : Item 251-252 (foot) with codenumber 4822 462 42159 has been

changed from “MATT SILVER”into “GLOSSY SILVER”.
The new codenumber for the GLOSSY SILVER foot reads
4822 462 11174.

REMARKS : The modification has been implemented in production from week

0047 onwards.

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

SYMPTOM :

Not reading/recording of Non-Philips branded CDR-discs respectively
Philips Megalife disc produced by Mitsui.

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.

01.17 TYPENUMBER(S): FW-C1/21, FW-C10/21, FW-C100/21/21M/19

SYMPTOM :

The set functions normally with the following observation on the
Combi Board:

- Elcap 2225 4700µF / 16V becomes bloated.

- PC Board area below resistors 3246 and 3248 becomes blacken
with overheating sign.

CURE : The voltage across Elcap 2225 is close/higher than its rated voltage

and resistors 3246 and 3248 are overstressed.
The problem is resolved by the following modification:

1. Replace Elcap 2225 with 4700µF / 25V (4822 124 12012).

2. Replace resistors 3246 and 3248 by 3 pieces of 330Ω 1/6W

(4822 116 52219) each as follows:

• replace 3246 and 3248 by 330Ω 1/6W

• solder 4 resistors 330Ω 1/6W across 3246 and 3248 on the
copper side as shown.

INFORMATION : To reduce failures of Power Amplifier IC 7391 (AN7125):

change capacitor 2355 from 2,2nF to 560pF 50V (5322 116 80853).

REMARKS : The modification has been implemented in production from week

INFORMATION : To reduce noise during Karaoke mode (generated by surround

passive components) change resistors 3634 and 3635 to 8,2kΩ 0,1W
(4822 051 20822).

REMARKS : The modification has been implemented in production from week

01.28 TYPENUMBER(S): FW-D1, FW-D5
INFORMATION : During the introduction of ASD-1 DVD Module there is a problem with

vibration noise during DVD play. This vibration noise is solved by the
addition of 2 screws D3 x 12 to tighten the ASD-1 DVD Module to the
Bottom plate (pos 236).

These additional screws have an impact on the dismantling steps
given in the Service Manual.The picture below shows the screw
location on the bottom plate (see screws V).
Take care when dismantling the DVD/DAC Module.

REMARKS :

01.29 TYPENUMBER(S): FW-D5/22

SYMPTOM :

Poor picture quality when the set is connected to the TV with a
standard SCART cable.

CURE : In the TV-set pin 19 and 20 are connected via an internal loop.

Via the standard SCART cable also pin 19 and pin 20 of the AV
Board are short-circuited. As pin 20 is grounded on the AV Board this
results in poor picture quality on the TV-set.

Interrupt the ground connection for SCART socket pin 20 on the AV
Board by cutting the copper track.

REMARKS :

01.30 TYPENUMBER(S): FW-V39

SYMPTOM :

The set is responding to some TV remote control codes

CURE : Some TV RC codes will activate VCD and other functions.

This problem is resolved by replacing the microprocessor IC 7401 on
the Front board by one with software version 17.
The new IC is available with othering code 9965 000 06154.

01.31 TYPENUMBER(S): FW-V39

SYMPTOM :

CD, Tape and Tuner not working, transistor 7233 (BD242BFP) blown.

CURE : Due to high inrush current at excessive mains supply values

transistor 7233 becomes defective (C-E shor ted). This causes a
sudden increase of supply voltages +PA, +LED, +12A and +12M
(jumping from +12 volts to +30 volts) killing other components along
the way.

SOLUTION: Reduce value of Elcap 2245 from 1000µF 16V to 220µF
16V (4822 124 40196).

REMARKS : Preventive action: In countries with high mains fluctuation it is

recommended to exchange 2245 on every set brought in for repair.

INFORMATION : Tape Deck Record/Playback head replacement tip.

After replacement of the Record/Playback head (pos 1) it is ver y
important to align it to the Forward position as given in picture below.
If this is not done, there is risk of damaging the gear.

REMARKS :

01.33 TYPENUMBER(S): MZ-3, MZ-33

SYMPTOM :

Hum noise picked up from transformer is audible.
CURE : Replace inductor 5553 by a jumper.
REMARKS : The modification has been implemented in production from week

0048 onwards.
