3.1 SAFETY INSTRUCTIONS
- Safety regulations demand that the set be restored to
its original condition and that components identical
with the original types be used.
Safety components are marked by the symbol A.
- ESD ~
~
All IC's and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce life
drastically.
When repairing, make sure that you are connected
with the same potential as the mass of the set via a
wrist wrap with resistance.
Keep components and tools also at this potential.
For detailed information see "Handling ESD-sensitive
components".
- A set to be repaired should always be connected to
the mains via a suitable isolating transformer.
- never replace any modules or any other parts while
the set is switched on.
- Use plastic instead of metal alignment tools. This in
order to prelude short-circuit or to prevent a specific
circuit form being rendered unstable.
3.2 SERVICING OF SMDs (Surface Mounted Devices)
3.2.1 General cautions on handling and storage
a. Oxidation on the SMDs terminals results in poor
soldering. Do not handle SMDs with bare hand.
b. Avoid for storage places that are sensitive to
oxidation such as places with sulfur or chlorine gas,
direct sunlight, high temperatures or a high degree of
humidity.
As a result the capacitance or resistance value of the
SMDs may be affected.
c. Rough handling of circuit boards containing SMDs
may cause damage to the components as well as the
circuit boards. Circuit boards containing SMDs should
never be bent or flexed. Different circuit board
materials expand and contract at different rates when
heated or cooled and the components and/or solder
connections may be damaged due to the stress.
Never rub or scrape chip components as this may
cause the value of the component to change. Similary,
do not slide the circuit board across any surface.
3.2.2 Removal of SMDs
a. Heat the solder (for 2-3 seconds) at each terminal of
the chip. Small components can, by means of litz wire
and a limited horizontal force, be removed with the
soldering iron. They can also be removed with a
solder sucker (see Fig. 1 a) or
b. While holding the SMD with a pair of tweezers take it
off gently using th soldering iron's heat applied to
each terminal (see Fig. 1 b).
c. Remove the excess solder on the solder lands by
means of litz wire or a solder sucker (see Fig. 1 c).
3.2.2.1 Caution on removal:
a. When handling the soldering iron, use suitable
pressure and be careful.
b. When removing the chip, do not use undue force with
the pair of tweezers.
c. The soldering iron to be used (approx. 30 W), must
preferably be provided with a thermal control
(soldering temperature about 225 to 250°C).
d The chip, once removed, must never be used again.

3.2.3.1 Caution on attachment:
a. When soldering the SMD terminals, do not touch them
directly with the soldering iron. The soldering must be
as quick as possible; care must be taken to avoid
damage to the terminals and the body itself.
b. Keep the SMD's body in contact with the printed
board when soldering.
c. The soldering iron to be used (approx. 30 W) must
preferably be provided with a thermal control
(soldering temperature about 225 to 250°C).
d. Soldering should not be done outside the solder land.
e. Soldering flux (of rosin) may be used but should not
be acidic.
f. After soldering, let the SMD cool down gradually at
room temperature.
g. The quantity of solder must be proportional with the
size of the solder land. If the quantity is too great, th€
SMD might crack or the solder lands might be torn
loose from the printed board (see Fig. 3).
3.3 HANDLING ESD-SENSITIVE COMPONENTS
3.3.1 Personal safety
The testing, handling and replacing of ESD-sensitve
components requires special attention for personal
safety. A person dealing with ESD-sensitive
components should, normally speaking, be connected
via a resistance to the same potential as the chassis
of the set to protect him against direct contact with
the supply voltage.
This resistance is often applied in the connection lead
of wrist wraps. If necessary, make use of an isolating
transformer.
3.3.2 Storage and transport
Transport and store the circuits and PCBs in their
original packages.
As an alternative to the original package one may use
a conductive material or special IC package which
short-circuits all the pins of the component with one
another.
Always discharge the package before opening it.
3.3.3 Testing or handling
Work on a conductive surface when testing loose
circuits and components or when transferring
components and circuits from one package to
another.
Use a conductive wrist wrap with lead to make an
electrical connection between the conductive surface
and yourself via a resistance in the connection lead of
the wrist wrap.
Connect equipment and tools also with this conductive
surface.
Do not connect any signals to inputs as long as the
power supply of the set to be tested is off.
All the inputs that are not used should be connected
either to ground or to the supply voltage. When
testing, do not use any freon sprays for under-cooling
of sensitive components.
3.3.4 Mounting ESD-sensitive components
Mount ESD-sensitive components only after all other
components have been mounted.
Make sure that the components themselves, the metal
parts of the PCB, mounting equipment and mounting
operator are at the same potential level as the chassis
of the set.
If it is impossible to ground the PCB, the mounting
operator should pick the PCB up before bringing it
into contact with the components to be replaced.
Conductive sheet
Bit
3.3.5 Soldering
Soldering iron tips, also those of low-voltage soldering
stations. should be kept at the same potential as the
components and the PCB.
It is better to use solder-removing braid than solder
suckers.
3.3.6 Electrostatic charges
One should stick to the precautionary measures also
after the ESD-sensitive components have been
mounted on the PCB. Until the sub-PCBs have been
incorporated into a complete system on which the
correct supply voltages are connected, the PCB is
nothing more than an extension of the conductors of
the components on this PCB. To prevent electrostatic
discharges from passing to the components via the
terminals, we recommend that you apply conductive
clips or conductive tape on the terminals of the PCB.
3.3.7 Transients (switch-on phenomena)
To prevent permanent damages as a result of
switch-on phenomena, no ESD-sensitive components,
or PCBs populated with these components, should be
inserted in or removed from test-sockets or systems
with the supply voltage on.
Prevent switching peeks on the mains as a
consequence of switching electric equipment, relay
and DC lines on and off.
3.3.8 Working environment
The work bench for the service technician should look
like the one shown in the figure.
3.3.9 Replacement of the Flat Pack IC's
For replacing a component see Fig. 6 Dismounting
and Mounting. Also a number of precautions and
examples is given.
When replacing a flat pack, rosin flux applied to the
device leads will ensure a good soldered joint.
Since rosin flux, when not properly heated by the
soldering process, is sticky, it will attract dust which
will result in component degeneration over a period of
time.
The removal of excess flux with a cleaner will not
solve this problem because the flux is then even
spread over a greater area by the cleaner. Drying of
the flux can be accomplished by blowing the area with
a common hair dryer for 1 or 2 minutes at a distance
of approx. 10 centimeters.
Soldering iron
Special attention should be paid in regions having a
dry atmosphere and when the floor is covered with a
nylon carpet or such.

PHILIPS SAFETY GUIDELINES FOR THE PROFESSIONAL SERVICE TECHNICIAN
Important
Fire and Shock Hazard (Continued)
Proper service and repair Is Important to the safe, reliable operation 9.
of all Phillps equipment. The service procedures recommended by
Philips and described In this service manual are effective methods of
performing service operations. Some of these service operations
require the use of tools specially designed for the purpose. The
speclal tools should be used when and as recommended.
After reassembly of the unit, always perform an ac leakage
test or resistance test from the line cord to all exposed metal
parts of the cabinet. Also, check all metal control shafts (with
knobs removed). antenna terminals, handles, screws, etc. to
be sure the unit is safe to operate without danger of electrical
shock.
It Is Important to note that this manual contains various CAUTIONS
and NOTICES which should be carefully read in order to minimize the

might be done or of the possible hazardous consequences of each
way. Consequently, Phlllps has not undertaken any such broad
evaluation. Accordingly, a servicer who uses a service procedure or
tool which Is not recommended by Phillps must first .satisfy himself
thoroughly that neither his safety nor the safe operation of the
equipment will be jeopardized by the service method selected.
Safety Checks
After the original service problem has been corrected, a complete
safety check should be made. Be sure to check over the entire set.
not Just the areas where you have worked. Some previous servicer
may have left an unsafe condition, which could be unknowingly
passed on to your customer. Be sure to check all of the following:

Unplug the ac line cord and connect a jumper between the two
prongs of the plug.
Turn on the power switch.
Measure the resistance value between the Jumpered ac plug
and all exposed cabinet parts of the receiver, such as screw
heads, antennas, and control shafts. When the exposed
metallic part has a return path to the chassis, the reading
should be between 1 megohm and 5.2 megohms. When the
exposed metal does not have a return path to the chassis the
reading must be infinity. Remove the jumper from the a~ line

Check across-the-line components and other components for
physical evidence of damage or deterioration and replace If
necessary. Follow original layout, lead length, and dress.
No lead or component should touch a resistor rated at 1 watt or
more. Lead tension around protruding metal surfaces or edges
must be avoided. 5.
Use an ac voltmeter with at least 5000 ohms/volt sensitivity to
measure the potential across the resistor.
The potential at any point should not exceed O. 75 volts. A
leakage current tester may be used to make this test: leakage
current must not exceed 0.5 milliamps. If a measurement is
outside of the specified limits, there Is a possibility of shock
hazard. The receiver should be repaired and rechecked before
returning It to the customer.
Repeat the above procedure with the ac plug reversed. (Note:
An ac adapter ts necessary when a polarized plug Is used. Do
not defeat the polarizing feature of the plug.)
Crltlcal components having special safety characteristics are
Identified with aA by the Ref. No. In the parts 11st and enclosed
within a broken line• (where several crltlcal components are
grouped In one area) along with the safety symbol
A on the schematic diagrams and/or exploded views.
Parts Replacement
Replacement parts without the same safety characteristics
may create shock, fire, or other hazards.
When servicing any unit, always use a separate Isolation
transformer for the chassis. Failure to use a separate Isolation
transformer may expose you to possible shock hazard, and
may cause damage to servicing Instruments.
Many electronic products use a polarized ac line cord ( one wide
pin ·on the plug). Defeating this safety feature may create a
potential hazard to the servicer and the user. Extension cords
which do not Incorporate the polarizing feature should never be
used.
LASER NOTE:
1.
2.
Many electrical and mechanical parts In Phillps equipment have
special safety related characteristics. These characteristics
are often not evident from vtsual inspection nor can the
protection afforded by them necessarily be obtained by using
replacement components rated for higher voltage, wattage,
etc. The use of a substitute part which does not have the same
safety characteristics as the Philips recommended
replacement part shown In this service manual may create
shock, fire, or other hazards. Under no circumstances should
the orlgtnal design be modified or altered without written
per1:1lsslon from Phillps. Phillps assumes no llablllty. express or
Implied, arising out of any unauthorized modification of design.
Servicer assumes all liability.
All lCs and many other semiconductor parts are susceptlble to
electrostatic discharges (ESD). Careless handling during
repair can reduce the life of the part drastically.
DANGER - lnvlslble laser radiation when open. AVOID DIRECT EXPOSURE TO BEAM.
CAUTION - Use of controls or adjustments or performance of procedures other than those specified herein may result In hazardous
radiation exposure.
CAUTION - The use of optical Instruments with this product will Increase eye hazard.

In
the setthere are 2 different testsoftware available:
1. Low Level test
2.
Service Shell
5.1
THE LOW LEVEL MMC
TEST
Scope
This test
is
standard implemented in the
b,oqt
software of
CD-RTOS. It doesn't need a lot of hardware to
run.
When
debugging or servicing an MMC panel this test is very
useful. The Low Level test
in
Menu driven.
To run the low level test a terminal (or equivalent) must
be
connected to port 2
(=
BU2). To startthe test the space-bar
on the terminal must be pushed atthe same that the power
is switched on at the COi-player. To continue with the test,
the instuctions
on
the screen of the terminal must be
followed.
5.1.1

ITEM 0 : EXIT LOW LEVEL
TEST
Selecting this item will end the lltest and continue with the
boot. After the boot the player shell is started up.
ITEM
1 :
Writing to
a
default RAM address
This test writes the powers of 2 to a
(word)
address. The
result is read again and will be displayed. The address can
be selected by the user ( only word adresses ). Pressing
'ESC' stops the test.
If one trys to write to unused space in the memory map, the
program will NOT generate an error message and the
system will hang up.
ITEM 2 : ROM parity check
For the
ROM
the following information is displayed and
checked:
-Display the identification code for this ROM (ROM
ID)
-Display the release number of this ROM
-Dispiay the checksum
of
this ROM. The upper word of
the checksum displayed is always '0000'.
Ifthe checksum is not ok then a specific error will be
displayed. This error is the same as in the pcb low level
test.
ITEM
3 :
NVRAM test
For the NVRAM test three different tests can be selected:
• The first is a non destructive nvram test as in the pcb low
level test.
-The second test is a destructive nvram test with ROM
data as test data.
-The third test is also a destructive test with the address
as data.
-The third test has also some hidden functions. Pressing :
w : writes continu the address as datato the nvram.
r:
reads continu the complete nvram ( no display).
d : displays the contents
of
421
succeeding
ram
locations. The start address is given
by
the user.
ESC : stops these functions.
ITEM4:
DRAM
The dram test is always a destructive test. The test is
performed for both ram CHIP1 and CHIP2 as one large
memory followed by a test for each bank separately.
The following actions take place in the dram test:
1.
fill the memory with the long word address as data.
2.
read the memory contents and compare with the
address.
3.
ifthe long word read is
ok
then continue else give
error message and stop testing.
4. write the inverted long word address as data to
memory.
5.
read the memory contents and compare with the
inverted address.
6.
if the long word read is ok then continue else give
error message and stop testing.
This test has also some hidden functions. Pressing :
w : writes continu the long address as data to the
dram.
r : reads continu the dram (
no
display ).
d : displays the contents of
421
succeeding
ram
locations. The start address is given by the user.
ESC:
stops these functions.

ITEM
6:
SLAVE processor
This lltestfor the slave performs following actions:
1.
Write
$FD
to the slave processor.
2.
Read byte from same address, the slave should
respond with
$FD.
3. If data is not
$FD
then stop testing and display
error code else continue with next action.
4. Read the next byte: this byte is the release number
of
the slave processorfirmware. Displaythe
release number. Ifthe release number is $00 then
an error will
be
displayed.
5. Read the next byte: this byte is the release number
ofthe CD processor firmware. Display the release
number. Ifthe release number is $00 then
an
error
will be displayed.
6.
Read the next byte: this is a dummy read.
ITEM 7 : Chip Select test
This step is only intended to be used with an oscilloscope.
The software will generate a Chip Select pattern for All
devices.It is not guaranteed that this test always runs. If one
of the devices is defective ( no
DTACK)
it will surely result
in
a hang-up
of
the testsoftware.
The devices are DRAM 1, DRAM
2,
SYSTEM ROM, DSP,
SLAVE, NVRAM and KILLME & DMAEN

5.2 THE SERVICE SHELL
Introduction.
For service purposes the CD-I set has built-in testsoftware
modules. These modules can be activated via the service
shell
by
menu.
The modules are for the testing of :
-Video circuitry, by means ofa colorbar testpatern
-
COM
and servo circuitry
Testing the COM, servo and audio cicuitry
in
the service
shell
is
only possible with a CD-DA disc.
5.2.1
Starting the service shell
The service shell can be started by connecting the RXD and
TXD lines ofport 1 (pin2 and pin3) during start up (insert
testplug before power on or reset).
5.2.2 Layout info
selectable/non selectable items
Each menu ofthe service shell consist ofa number of
boxes and text strings. Some ofthese boxes can be
selected by moving the screen cursor above the box and
clicking on one ofthe joystick buttons. Only the colored
boxes can be selected. Clicking on one
of
the other boxes
will have no effect.
(error) messages on the screen
The service shell will provide information and errors
in
a box
at
the top of the screen.
To
remove such a message and
continue with the test a button must be clicked on the
remote control joystick.
menu structure
When the service shell is started, the main menu appears
with a number
of
boxes on
it.
Selecting some boxes will
result
in
a submenu being displayed, other boxes may result
in
immediate action. Selecting the EXIT box will stop the
service shell and restart the player. Selecting EXIT
in
a
submenu will return you to the previous menu.
5.3.3 Subject dependent information
Main menu
The main menu contains two test item boxes and the EXIT
box. Selecting TEST IMAGE will give immediate action, the
CD
DRIVE will start the CD DRIVE test submenu.
CD drive test
The
CD
drive test will perform the service loop as
implemented in the Philips CD audio players. A disc
is
needed for this
test
Results
of
this test will be displayed on
the screen instead of a display. When the cd drive test is
selected, the same screen will appear, but with other
buttons highlighted. You cannot select the X bus and Dig
Out test anymore. Selecting the EXIT button will return you
to the
cd
menu. (X bus and Dig Out button highlighted
again). The drive test consist
of
the following steps:

MODE0
Software release number of the CD micro processor is
displayed in the button at the left top ofthe screen (cd
status button).Mode 0 is displayed
in
the button at the right
top of the screen (mode button). During the cd drive test this
button will display the current mode.
In
mode
0,
the ARM IN and ARM OUT buttons can be
selected to move the
cd
lense inwards and outwards.
Selecting NEXT STEP will bring the player in mode
1.
MODE1
In mode 1 the
cd
driveprocessor will try to focus. If it
manages to do
so
(a disc must be present!), the message
IN FOCUS will appear in the status button. Otherwise, the
message
NO
FOCUS will appear in the status button after
the
cd
driveprocessor has tried to focus 16 times {this may
take a while).
In
that case (no focus found) the test will
return to mode
0.
Selecting NEXT STEP will bring the player
in
mode
2.
MODE2
The turntablemotor is rotating and controlled by the rough
HF, moving the
cd
lense outside (by hand) will slow the disc
down.
If
an
error occurs, the test will return to mode
0.
Selecting NEXT STEP
in
mode 2 will bring the player
in
mode
3.
MODE3
You can select ARM IN and ARM OUT to make the
cd
lense jump inside or outside (small jumps). The laser will
keep jumping while a button is pressed on the remote
control.
Ifan error occurs, the test will return to mode 0.
NEXT STEP
in
mode 3 will bring the player in normal
playing mode.
MODE4
In
this mode the CODA shell will appear like playing
normally.
If something goes wrong, then the errors which will be sent
by the
CD
processor will be displayed
in
a box on the
screen. You cannot return to the service shell otherwise
than by resetting the player.

Video test image
A
colorbar will be displayed on the screen. Pressing a
button after the screen has been filled completely will return
you to the main menu. There are no error messages for this
test.
What
could be wrong
if...
Service shell cannot be started with the testplug.
Connections between port 1 and slave may be bad.
Testplug could be wrong. Maybe the slave processor is
defect. If the playershell cannot be started either, try the low
level test first.
