06.01 TYPENUMBER(S): Philips CD-recorders and copy-protected Audio CDs

INFORMATION : A number of music record companies have introduced so-called

“copy-protected” CDs.These CDs aim to obstruct copying to CDR
discs via the PC while they are supposed to play on conventional CD­players.

However, in practice, the copy-protected CDs might not play on all
models of Audio CD-recorders, DVD-recorders, PC-drives and in-car
CD-players because these CDs are no longer in accordance with the
CD Red Book specification.

If you get complaints from customers facing playback problems,
please inform them that the CD is likely to be faulty, and advice the
customers to take the CD back to the shop and ask for refund.We
suggest refraining from debates about details of the copy-protection
technology, as this technology is being applied by the music record
company, and not by Philips.

03.12 TYPENUMBER(S): FW-R7, FW-R8, FW-R88

SYMPTOM :

The CDR Module does not work correctly with ComPair.

Known problems:

1. Download of a new software version does not function

2. “Dead module” after replacement

CURE : 1.When the CDR Module is supplied by the Power Supply Unit of the

set, always make sure that

• the set is switched to CDR-mode and

• the Front-, AF-, Power L/R- and Supply CDr/w Boards are
connected properly.

This is necessary because the +5V supply for the CDR Module is
controlled by the Front-µP.Via IIC-Bus and IIC-shift register
(located on AF-Board) the CDR_ON signal is generated and via
Power L/R Board connected to Supply CDr/w Board.

2. Check solder connections of DASP IC.
Past experience has shown that most communication errors are

caused by weak solder connections of the DASP IC (item 7701).

REMARKS : After download of a new software version also look to the final

message that download was done successfully!

03.13 TYPENUMBER(S): FW-V220, FW-V320 and FW-V720

SYMPTOM :

No music, only noise is audible during MP3 playback.

CURE : Due to residual voltage, the MPEG board does not get a proper reset.

The problem can be resolved by the following rework
(see drawings on next page):

1. Cut a copper track

2. Add a resistor 1kΩ (4822 050 21002) across +5V and ground

3. Add a resistor 10kΩ (4822 050 21003)

4. Add diode 1N4148 (4822 130 30621)

will be completely wrong after switching on again.

CURE : The most probable reason is a leaky ceramic capacitor 2165

(resistance of a few hundred Ohm can be measured).
The defective capacitor causes a drop of Vref (1.5V instead of 2V at
pin 1 of IC7101) along with a drop of the internal stabilized voltages
VstabA and VstabB (0.8V instead of 1.4V at pins 34 and 38).
As a result IC7101 will not work anymore.

The problem can be solved by replacing capacitor 2165.

REMARKS : Check also ceramic capacitors 2139 and 2152.

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

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 try again.

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

3) Check the batteries and replace if necessary.

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.

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.

01.28 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 countr ies with high mains fluctuation it is

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