GB WARNING
All ICs 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.

CUSTOMER INFORMATION
It is proposed to add an addendum sheet to the set which
informs the customer that the set has been checked
carefully - but no fault was found.
The problem was obviously caused by a scratched, dirty or
copy-protected CD. In case problems remain, the customer
is requested to contact the workshop directly.
The lens cleaning (method 3) should be mentioned in the
addendum sheet.
The final wording in national language as well as the printing
is under responsibility of the Regional Service Organizations.

FAST LENS CLEANING (dry brush)
Use lens cleaning CD
SBC AC300...........................................9082 100 00043
Insert the lens cleaning CD, press PLAY and follow the
voice guide´s instructions on the CD.
4
LIQUID LENS CLEANING
Because the material of the lens is synthetic and coated
with a special anti-reflectivity layer, cleaning must be done
with a non-aggressive cleaning fluid. It is advised to use
“Cleaning Solvent B4-No2”, available with codenumber
4822 389 10026.
The actuator is a very precise mechanical component and
may not be damaged in order to guarantee its full function.
Clean the lens gently (don’t press too hard) with a soft and
clean cotton bud moistened with the special lens cleaner.
The direction of cleaning must be in the way as indicated in
the picture below.
Before touching the lens it is advised to clean the
surface of the lens by blowing clean air over it.
This to avoid that little particles make scratches on
the lens.

EYE-PATTERN SIGNAL – JITTER MEASUREMENT
Measure the signal on the input of the Signal processor
using an analog oscilloscope. Please find the exact
measuring point in your Service Manual.
See below examples of the signal. Amplitude should read at
least 700mVpp using SBC444A.
good
bad
If the oscilloscope shows a signal like the ‘bad’ one, and/or
the amplitude decreases within 1 minute - the CD drive has
to be replaced.
6
CD DRIVE – LASER CURRENT MEASUREMENT
The laser current can be measured as a voltage drop on a
resistor. The resistor is marked in every Service Manual.
The value depends on the type of CD drive.
typical value most probably defect
VAMxxxx : 150-230mV ≥350mV
MCDxx : 170-230mV ≥300mV
DA1x : 210-250mV ≥350mV
DA2x : 175-200mV ≥250mV
Use SBC444A (CD-DA) for measurement.
7
CD DRIVE – OFFSET MEASUREMENT
The photodiodes of the CD-drive may have an offset. These
offsets have to be compensated by the signal processor.
High offsets can lead to poor playability of some CDs
(skipping tracks).
To measure the offset values, start the Service Test
Program - section “Focus Test” without a CD.
The offsets can be measured with a DC Millivoltmeter
directly on the connector (see drawing below). Pin
numbering varies from drive to drive.
The values from diode A-D should read 0±10mV.
Diodes E and F are less critical.
If one of the offsets is higher than ±10mV the CD drive has
to be replaced. Otherwise replace the Signal Processor.

CONNECTION AND CONTROLS
Step 1: Placing speakers
Place the front left and right speakers at equal distances from the TV set and at an angle of approximately 45 degrees from the listening position. Notes: –To avoid magnetic interference, do not position
the front speakers too close to your TV set. –Allow adequate ventilation around the DVD System.
IMPORTANT! –The type plate is located at the rear of the system. –Before connecting the AC power cord to the wall outlet, ensure that all other connections have been made. –N
ever make or change any
connections with the power switched on. –High voltage! Do not open.You run the risk of getting an electric shock. –The machine does not contain any user- serviceable parts. –Modification of the product could result in hazardous radiation of EMC or other unsafe operation. To avoid overheating of the system, a safety circuit has been built in.Therefore, your system may switch to Standby mode automatically under extreme conditions. If this happens, let the system cool down before reusing it (not available

Step 4: ConnectingTV
IMPORTANT! –Y
ou only need to make one video
connection from the following options, depending on the capabilities of yourTV system. –Connect the DVD system directly to theTV.
Using Video In jack (CVBS)
1Use the composite video cable (yellow) to
connect the system's VIDEO jack to the video input jack (or labelled as A/V In,Video In, Composite or Baseband) on the TV set.
2To hear the sound of this DVD Player through
yourTV, use the audio cables (white/red) to connect LINE OUT (L/R) jacks of the DVD
Player to the corresponding AUDIO IN jacks on the TV.
Step 2: Connecting speakers
Connect the speaker wires to the SPEAKER
terminals, right speaker to "R" and left speaker to "L", coloured (marked) wire to "+" and black (unmarked) wire to "-". Fully insert the stripped portion of the speaker wire into the terminal as shown. Notes: – Ensure that the speaker cables are correctly connected. Improper connections may damage the system due to short-circuit. –For optimal sound performance, use the supplied speakers. – Do not connect more than one speaker to any one pair of +/- speaker terminals. – Do not connect speakers with an impedance lower than the speakers supplied. Please refer to the SPECIFICATIONS section of this manual.
Step 3: Antenna connection
Connect the supplied FM antenna to the respective terminal. Adjust the position of the antenna for optimal reception.
FM Antenna ●For better FM stereo reception, connect an
outdoor FM antenna to the FM AERIAL (FM ANTENNA) terminal.

3 - 2
CONNECTION AND CONTROLS
Using an accessory RF modulator
IMPORTANT! –If yourTV set only has a single Antenna In jack (or labelled as 75 ohm or RF In), you will need a RF modulator in order to view the DVD playback via TV. See your electronics retailer or contact Philips for details on RF modulator availability and operations.
1Use the composite cable (yellow) to connect the
system's VIDEO jack to the video input jack on
the RF modulator.
2Use an RF coaxial cable (not supplied) to
connect the RF modulator to yourTV's RF jack.
Using component Video In jack (Pr PbY)
●Use the component video cables (red/blue/
green, not supplied) to connect the system’s PR/ PB/Y jacks to the corresponding Component video input jacks (or labeled as Pr/Cr Pb/Cb Y or YUV) on the TV set.
●To listen to TV channels through this system, use
the audio cables (white/red) to connect AUX IN (L/R) jacks to the corresponding AUDIO OUT jacks on the TV set.

IMPORTANT! –Never make or change any connection with the power switched on. the AC power adaptor to the system and then to the power outlet.
Optional: Connecting additional equipment
IMPORTANT! –Some discs are copy-protected.You cannot record the disc through a VCR or digital recording device. –When making connections, make sure the colour of cables matches the colour of jacks. –Always refer to the owner's manual of the other equipment for complete connection and usage details.

Listening to the playback of other equipment A Use a cinch cable to connect AUX on the rear panel of the DVD player to the analogue audio out terminals of an external equipment (TV,VCR, Laser Disc player, DVD player or CD Recorder).
Before starting operation, press SOURCE on
the front panel to select AUX or press AUX on
the remote in order to activate the input source. Note: –If you are connecting equipment with a mono output (a single audio out terminal), connect it to the AUX left terminal. Alternatively, you can use a “single to double” cinch cable (the output sound still remain mono).
