f ATTENTIONTous les IC et beaucoup d´autres semi-conducteurs sontsensibles aux décharges statiques (ESD). Leur longévitepourrait être considérablement écourtée par le fait qu´aucuneprécaution nést prise à leur manipulation.Lors de réparations, s´assurer de bien être relié au mêmepotentiel que la masse de l´appareil et enfileer le braceletserti d´une résistance de sécurité.Veiller à ce que les composants ainsi que les outils que l´onutilise soient également à ce potentiel.
d WARNUNGAlle ICs und viele andere Halbleiter sind empfindlichgegenüber elektrostatischen Entladungen (ESD).Unsorgfältige Behandlung im Reparaturfall kann dieLebensdauer drastisch reduzieren.Sorgen Sie dafür, daß Sie im Reparaturfall über ein Puls-armband mit Widerstand mit dem Massepotential desGerätes verbunden sind.Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesemPotential.
ñ WAARSCHUWINGAlle IC´s en vele andere halfgeleiders zijn gevoelig voorelectrostatische ontladingen (ESD).Onzorgvuldig behandelen tijdens reparatie kan de levensduurdrastisch doen vermindern. Zorg ervoor dat u tijdens reparatievia een polsband met weerstand verbonden bent met hetzelfdepotentiaal als de massa van het apparaat.Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.
i AVVERTIMENTOTutti IC e parecchi semi-conduttori sono sensibili alle scarichestatiche (ESD).La loro longevità potrebbe essere fortemente ridatta in caso dinon osservazione della più grande cauzione alla loromanipolazione. Durante le riparationi occorre quindi esserecollegato allo stesso potenziale che quello della massadelápparecchio tramite un braccialetto a resistenza.Assicurarsi che i componenti e anche gli utensili con quali silavora siano anche a questo potenziale.
iLe norme di sicurezza estigono che l´apparecchio vengarimesso nelle condizioni originali e che siano utilizzati ipezzi di ricambiago identici a quelli specificati.Componenty di sicurezza sono marcati con
ñVeiligheidsbepalingen vereisen, dat het apparaat in zijnoorspronkeliijke toestand wordt teruggebracht en datonderdelen, identiek aan de gespecificeerde, worden toegepast.De Veiligheidsonderdelen zijn aangeduid met het symbool
s Varning !Osynlig laserstrålning när apparaten är öppnad ochspärren är urkopplad. Betrakta ej strålen.
∂ Advarsel !Usynlig laserstråling ved åbning når sikkerhedsafbrydere er ude af funktion. Undgå udsaettelse for stråling.

LEAD FREE PRODUCED SET
This set is manufactured with lead-freeproduction technology. This is also indicated bythe PHILIPS-lead-free logo you find on theprinted boards.
The set is produced with lead-free solder-alloy as well aswith lead-free sub-parts. It can be considered as lead-free.Due to this fact some rules have to be respected by theworkshop during a repair:
• Use only lead-free soldering-tin Philips SAC305 with ordercode 0622 149 00106. If lead-free solder-paste is required,please contact the manufacturer of your solder-equipment.
• Use only adequate solder tools applicable for lead-freesoldering-tin.
• Adjust your solder tool so that a temperature around 217°– 220° is reached at the solder joint.
• Do not mix lead-free soldering-tin with leaded soldering-tin.This would lead to unreliable solder joints.
• On our website http://www.atyourservice.ce.philips.comyou find more information to
– aspects of lead-free technology– BGA-de-/soldering, heating-profiles of BGAs used in
Philips-sets, and others.

Wessli Module – Firmware Upgrade
The firmware of the Wessli Module can be upgraded viawireless network. The network is used to transfer the newfirmware from the PC to the on-board Flash-ROM (IC7103). Firmware and related tools are usually distributed aszip-archive.
To upgrade the firmware of the Wessli Module proceed asfollows:
1. Insert the MCW770 Setup-CD into the CD-drive of thePC and walk through the consumer installation.
2. Create a new folder “WiFiUpgrade” on the PC hard diskand extract the content of the supplied zip-archive to thislocation. The folder should contain the following files:
3. Open the Wireless LAN Utility via WiFi icon in the systemtray (right-click the icon and click on “View AvailableNetwork”).
4. Apply the following settings in the configuration tab:
5. Disable encryption in the security tab:
6. Open the “TCP/IP properties” in “Windows Network andDial-up Connections” and ensure that “Obtain an IPaddress automatically” is selected.
7. Put the MCW770 into Installation mode as follows:• Hold the PC-LINK button depressed for at least 5s.• The display shows “INSTALLING”.• Wait for another 15s.• Hold the BROWSE button depressed for at least 2s.• Wait for another 15s.• The display shows “EXPERT INSTALL” and the color of
the WiFi icon in the system tray turns to green.• Wait for another 90s to ensure that the set has
optained its IP address.
WiFi icon
8. Run “WiFiUpdate.exe“ from the folder created in step 2and mark the firmware upgrade file inside this folder.
9. Finally, start the firmware upgrade as follows:• Click the START button in the WiFi Upgrade utility.• Dialog “Press OK to start Upgrade” pops up.
• Click the OK button.• A command window opens and shows:
• The display on the set shows “PRESS PLAY TOUPGRADE PROG”.
• Press the PLAY button on the set.• After a few seconds the upgrade utility reports
“Upgrade successful” and the display on the set shows“COMPLETED”.

In case of symptom „skipping tracks“ perform fol-lowing actions:
1. VERIFY THE COMPLAINT
PLAYABILITY CHECK
Use CDDA SBC 444A: . . . . . . . . . . . . .4822 397 30245TR 14 (600µ black dot) maximum at 01:15 TR 19 (fingerprint)TR 10 (1000µ wedge)
Use CD-RW Printed Audio Disk . . . . . .7104 099 96611TR 3 (Fingerprint)TR 8 (600µ black dot) maximum at 01:00
• playback of all these tracks without audible disturbance• jump forward/backward within a reasonable time
2. CLEAN THE LENS
CD DRIVE – LENS CLEANING
Because the material of the lens is synthetic and coatedwith a special anti-reflectivity layer, cleaning must bedone with a non-aggressive cleaning fluid. It is advised touse “KODAK LENS CLEANER CAT 176 71 36”, availablein normal photo shops.
The actuator is a very precise mechanical componentand may not be damaged in order to guarantee its fullfunction. It is advised to clean the lens gently (don’t presstoo hard) with a soft and clean cotton bud moistened withthe special lens cleaner.
The direction of cleaning must be in the way as indicatedin the picture below.
3. MEASURE THE EYE-PATTERN SIGNAL
EYE-PATTERN SIGNAL – JITTER MEASUREMENT
Measure the signal direct on resistor 3898 using an oscil-loscope (see also chapter 10-9).
See below examples of the signal. Amplitude should read atleast 700mVpp using SBC444A.
good
badIf the oscilloscope shows a signal like the ‘bad’ one, and/orthe amplitude decreases within 1minute - the CD drive hasto be replaced.

4. MEASURE THE LASER CURRENT
CD DRIVE – LASER CURRENT MEASUREMENT
The laser current can be measured as a voltage drop onresistor 3820. Typical value 170 - 190mV for CD-DA res-pectively 200 - 220mV for CD-RW.
5. MEASURE THE OFFSETS OF THE CD-DRIVE
CD DRIVE – OFFSET MEASUREMENT
Each photodiode of the CD-drive may have an offset.This offset has to be compensated by the signal proces-sor. A high offset of the CD-drive leads to poor playabilityof some CDs (skipping tracks).
Start the Service Test Program - section „Focus Test“without a CD. Focus sensitivity = CD-RW.
Use a DC Millivoltmeter for measurement. The offsetscan be measured direct on the connector. See drawingbelow.
The values from diode A-D should read0±10mV. Diodes E and F are less critical.
If one of the offsets is higher than ±10mV the CD drivehas to be replaced.

Basically Class-D works by transforming the LF audio inputto a square wave signal with a fixed frequency and avariable duty cycle. See simplified drawing below.
The amplitude of the square wave signal is equal to thesupply voltage of the amplifier. With the audio signal thesquare wave signal is pulse-width modulated.
Compared to a conventional power amplfier the benefits ofthe Class D amplifier are:
Disadvantage of this concept is:• 500kHz square wave signal with high current requires a
shielding box to suppress radiation.
Required Circuitries:
• 500kHz square wave oscillator .The oscillator frequency is created by 7312-3; it is adual-frequency oscillator with ceramic resonators 5300and 5302, which resonate at 500kHz and 425kHzrespectively. The resonators are switched by transistors7309 and 7316, controlled by the "OZ_SW" line from theport expander 7406.The reason for 2 frequencies is to avoid tunerdisturbances in the AM-band.The oscillator signal is shaped to square wave with7312-2, afterwards buffered and fed to the amplifiermodulators (ROZ to the right channel, LOZ to the left).One channel gets inverted clock to balance supplyloading.
• ModulatorThe modulator forms the pulse width modulated signal.For each channel a seperate modulation is required.
• Power FETsThe FETs require drivers which supply the gates. One forthe high-side-FET and one for the low-side-FET.Because of the different supply voltages also anadditional level shifter is necessary per driver.
• Output filterThe output filter is necessary to block the 500kHz squarewave signal from the speaker.Refers to the left channel in schematic diagrams.It consists of a series-mode coil 5101 and a capacity ofapprox. 550nF (2116, 2134), which forms a Chebychefffilter with 40kHz cut-off frequency at 6Ω load. For EMCreasons both, the speaker output and the return groundare fed through a common mode coil (5102). The filter isfurther improved by splitting the output capacity into2116 before and 2134 after the common mode coil.
All above mentioned circuitries are located inside the metalshielding box.

Functional Description:
Refers to the left channel in schematic diagrams.The first stage of the modulator is an error integrator whichcompares the input to the (24 dB amplified) output signal ofthe power stage. The difference is leading to a current,which loads the integrator 7122-A. The second stage(7122-B) adds the 500kHz rectangular oscillator signal,creates high gain and low distortion and is againintegrating. The output signal leads to a triangle wave form(see oscillogram E). The DC value of this triangle signal isfloating, dependent on the amplitude of the analog inputsignal. The next stage is a comparator, which compares theintegrated voltage with the internal switching levels - thuscreating a voltage controlled duty cycle. 7122 C and Dimprove the shape of the pulses. For details seeoscillograms A-F.At pin 8 of IC7122 there is a square wave with the samefrequency and duty cycle as the desired output.
The next task is to feed this information to the output FETs.Both FETs are n-channel types, so they are modulated byfeeding the gate in respect to the source connection.Inverters 74LV14 are used as drivers. The driver for the low-side FET (7121) is supplied by the negative supply -VL2and a voltage +VL (generated by 7115 and 6113), which is7.5V higher than -VL2. The digital signal is level-shifted by7128 to the low side driver stage. 3142, 6111 and 2126together form a delay circuit for rising edges by approx.100ns for the low side FET. 3154, 6109 and 2137 delay therising edge by 50ns for the high side FET. This tocompensate the switch-off delay of the FETs and ensuresthat both FETs are not conducting at the same time.The high-side FET (7109) is controlled by the invertedsignal taken from pin 2 of 7118, which is level-shifted bytransistor 7119. The driver for the high-side FET is suppliedby a floating voltage between the amplifier output -V1L and+V1L, created by the charge pump 6110, 2114 regulated by7114 and 6114 to a 7.5V higher level. The pump isadditionally supplied (via 3151) by +45V to ensure supply atstart-up (no signal). The last stage in the gate driverconsists of three gates in parallel for increased outputcurrent for the capacitive load of the FET. For additionalincrease of the switching speed push/pull transistors7132/7111 are added.
Protection Circuits:
The amplifier is protected against low load impedance(including short circuit). Current is sensed by shunts 3101,3130 in both supplies. Overcurrent at the positive supply isthen sensed by 7104, the negative supply overcurrenttriggers 7117, which then also triggers 7104. The collectorcurrent in turn triggers the monoflop 7122-5 and -6, giving a"High" pulse at pin 10. This shuts off level-shifter 7128 andblocks transistor 7129 and 7131, which draws current intothe emitter resistor 3134 of level-shifter 7119. It is now alsoshut off. So, both FETs are shut off within approx. 0,2 sec.The monoflop can be reset by:- switching mains off and on again- pressing Standby button and afterwards any source button- plugging headphone in for a short moment
When a headphone is used the amplifier is shut off. This isdone by pulling pin 13 of 7122 via signal line "AMP_OFF"and transistor 7130 to high level. The line "AMP_OFF" iscontrolled by the port expander 7406 which detects theheadphone via signal line "HP_DET".
The loudspeakers are protected against DC voltagesresulting e.g. from defective FETs. Voltages higher than ±2Vare detected by 7110 respectively 7112. The transistorsconduct and pull the "DC_PROT" line down, blockingtransistor 7243 which in turn disables speaker relay 1201.
Adjustments:
The gain of the class-D amplifier is 24dB, adjusted by thefeedback resistors 3155, 3136, 3149 and the input resistors3139, 3340. The input reference voltage for 7122-A isapprox. half the supply, therefore 3144, 3148 are used foroffset compensation. This compensation has to be fine-tuned with trimpotentiometers 3306 and 3307 to obtain<1mV DC output.
Service Hints:
The analog part of the Combi Board can be repairedwithout opening the metal shielding box. In case of a ‘ClassD’ problem it is advised to disassemble the board first,desolder the metal bottom cover of the shielding box andassemble the board again. This takes a few minutes only.
To de-solder the metal bottom cover proceed as follows:1)Remove top cover of shielding box to reduce heat flow2)Do not use de-solder wick3)Simply hold the board upright down as shown in picture 1.
Heat up solder joints and move tip of soldering iron slowlyalong the edge of the metal frame.Solder will flow along the soldering tip and rest on themetal plate. A small amount will drop off.A small gap will become visible as indication that thesolder connection is released.When all solder joints are released the cover can beremoved by help of a screwdriver. Begin at the cornerindicated by an arrow → see picture 2.
To re-mount the metal bottom cover proceed as follows:1)The solder connections are not distributed evenly.
Therefore the cover has to be mounted in that way thatthe arrow indicator on the cover is positioned in line withthe arrow printed on the printed board → see picture 3.

2)Press the metal cover smoothly down until the gapbetween cover and printed board becomes a minimum.This is important for proper shielding.
3)Heat up the residual solder on the metal cover. The solderwill flow back to the solder areas. If necessary applyadditional new solder.
4)Take care that all solder joints are re-soldered again.
Attention: Poor soldering of the metal shielding box resultsin disturbance of the tuner.
In most cases the FETs 7109 and/or 7121 for the leftchannel, respectively 7218 and/or 7231 for the right channelwill be defective. This can easily be checked with anordinary Ohm-meter.LEFT CHANNEL:In case 7109 is defect replace following parts:7109, 7111, 7132, 7105, 7119, 7104, 3101, 3103 and 2106
In case 7121 is defect replace following parts:7121, 7113, 7133, 7118, 7117, 3129, 3130 and 2118
RIGHT CHANNEL:In case 7218 is defect replace following parts:7218, 7221, 7244, 7209, 7228, 7208, 3205, 3209 and 2206
In case 7231 is defect replace following parts:7231, 7210, 7245, 7235, 7227, 3241, 3243 and 2220
Attention: Do not forget to adjust the DC-offset afterreplacing the FET!
If none of the FETs is defective the fault is most probablylocated in the modulator. To check the operation - follow thegiven signals.

In this pulse width modulated square wave the analogAudio signal is included. Measurements with an analogscope will show a jitter on the falling edge.
The modulator frequency is still fixed to 500kHz. Similar to afrequency modulation - in this case the amplitude of theanalog audio signal varies the pulse width, the frequencydefines the speed.
Measuring point G:
The low-side driver signal <G1> (Ch2) is the modulatoroutput level-shifted by transistor 7128. The high-side driversignal <G2> (Ch1) is the inverted low-side driver signallevel-shifted by transistor 7119.
Service Hints
Measuring point H: gate-signal of the FETs
Ch1 = H1, CH2 = H2
Measuring point I:
Digital output signal.
Measuring point J:The following three signals are measured after output filter5101 with different timebases.
Measuring point K:
After common mode coil 5102 - the audio signal is restored.
