HANDLING CHIP COMPONENTS

1-6

GB

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.

Tous les IC et beaucoup d’autres semi-conducteurs sont sensibles aux décharges statiques (ESD). Leur longévité pourrait être considérablement écourtée par le fait qu’aucune précaution n’est prise à leur manipulation. Lors de réparations, s’assurer de bien être relié au même potentiel que la masse de l’appareil et enfiler le bracelet serti d’une résistance de sécurité. Veiller à ce que les composants ainsi que les outils que l’on utilise soient également à ce potentiel.

WARNUNG

Alle ICs und viele andere Halbleiter sind empfindlich gegenüber elektrostatischen Entladungen (ESD). Unsorgfältige Behandlung im Reparaturfall kan die Lebensdauer drastisch reduzieren. Veranlassen Sie, dass Sie im Reparaturfall über ein Pulsarmband mit Widerstand verbunden sind mit dem gleichen Potential wie die Masse des Gerätes. Bauteile und Hilfsmittel auch auf dieses gleiche Potential halten.

ESD PROTECTION EQUIPMENT:

NL

Alle IC’s en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen verminderen. Zorg ervoor dat u tijdens reparatie via een polsband met weerstand verbonden bent met hetzelfde potentiaal als de massa van het apparaat. Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.

Tutti IC e parecchi semi-conduttori sono sensibili alle scariche statiche (ESD). La loro longevità potrebbe essere fortemente ridatta in caso di non osservazione della più grande cauzione alla loro manipolazione. Durante le riparazioni occorre quindi essere collegato allo stesso potenziale che quello della massa dell’apparecchio tramite un braccialetto a resistenza. Assicurarsi che i componenti e anche gli utensili con quali si lavora siano anche a questo potenziale.

INFORMATION ABOUT LEAD-FREE SOLDERING

Philips CE is producing lead-free sets from 1.1.2005 onwards.

IDENTIFICATION:

Regardless of special logo (not always indicated) one must treat all sets from 1 Jan 2005 onwards, according next rules:

Example S/N:

Bottom line of typeplate gives a 14-digit S/N. Digit 5&6 is the year, digit 7&8 is the week number, so in this case 2005 wk12

So from 0501 onwards = from 1 Jan 2005 onwards

Important note

: In fact also products of year 2004 must be treated in this way as long as you avoid mixing solder-alloys (leaded/ lead-free). So best to always use SAC305 and the higher temperatures belong to this.

Due to lead-free technology some rules have to be respected by the workshop during a repair:

• Use only lead-free solder alloy Philips SAC305 with order code 0622 149 00106. If lead-free solder-paste is required, please contact

the manufacturer of your solder-equipment. In general use of solder-paste within workshops should be avoided because paste is not easy to store and to handle.

• Use only adequate solder tools applicable for lead-free solder alloy. The solder tool must be able

o To reach at least a solder-temperature of 40 o To stabilize the adjusted temperature at the solder-tip o To exchange solder-tips for different applications.

• Adjust your solder tool so that a temperature around

− is reached and stabilized at the solder joint. Heating-time of the solder-joint should not exceed ~ 4 sec. Avoid temperatures above 400∞C otherwise wear-out of tips will rise drastically and flux-fluid will be destroyed. To avoid wear-out of tips switch off un-used equipment, or reduce heat.

• Mix of lead-free solder alloy / parts with leaded solder alloy / parts is possible but PHILIPS recommends strongly to avoid mixed

solder alloy types (leaded and lead-free). If one cannot avoid or does not know whether product is lead-free, clean carefully the solder-joint from old solder alloy and re-solder with new solder alloy (SAC305).

• Use only original spare-parts listed in the Service-Manuals. Not listed standard-material (commodities) has to be purchased at

external companies.

• Special information for BGA-ICs:

- always use the 12nc-recognizable soldering temperature profile of the specific BGA (for de-soldering always use the lead-free temperature profile, in case of doubt)

- lead free BGA-ICs will be delivered in so-called 'dry-packaging' (sealed pack including a silica gel pack) to protect the IC against moisture. After opening, dependent of MSL-level seen on indicator-label in the bag, the BGA-IC possibly still has to be baked dry. (MSL=Moisture Sensitivity Level). This will be communicated via AYS-website. Do not re-use BGAs at all.

• For sets produced before 1.1.2005 (except products of 2004), containing leaded solder-alloy and components, all needed spare-parts

will be available till the end of the service-period. For repair of such sets nothing changes.

• On our website www.atyourservice.ce.Philips.com

you find more information to:

∗

BGA-de-/soldering (+ baking instructions)

∗

Heating-profiles of BGAs and other ICs used in Philips-sets

You will find this and more technical information within the "magazine", chapter "workshop news".

For additional questions please contact your local repair-helpdesk.

SERVICE INSTRUCTION

1. Unplug the AC Power cord and connect a wire between the two pins of the AC Power plug.

2. Set the AC Power switch to the "on" position (keep the AC Power cord unplugged!).

3. Measure the resistance value between the pins of the AC Power plug and the metal shielding of the tuner or the aerial connection on the set. The reading should be larger than 4.5 Mohm (For U.S. it should be between

4.2 Mohm and 12 Mohm).

4. Switch "off" the set, and remove the wire between the two pins of the AC Power plug.

Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to the following points:

· Route the wire trees correctly and fix them with the mounted cable clamps.

· Check the insulation of the AC Power lead for external damage.

· Check the strain relief of the AC Power cord for proper function.

· Check the electrical DC resistance between the AC Power Plug and the secondary side (only for sets which have a AC Power isolated power supply):

• Check the cabinet for defects, to avoid touching of any

inner parts by the customer.

stripped portion of the speaker wire into the

terminal as shown.

Helpful Hint:

– Ensure that the speaker cables are correctly

connected. Improper connections may damage the

system due to short-circuit.

– Do not connect more than one speaker to any

one pair of +/- speaker terminals.

Step 3: Connecting the AC

power cord

Service hints

In case of symptom „skipping tracks“ perform following actions:

1. VERIFY THE COMPLAINT

PLAYABILITY CHECK

use CD-RW Printed Audio Disk . . . . . .7104 099 96611

TR 3 (Fingerprint) TR 8 (600µ black dot) maximum at 01:00

• playback of these two tracks without audible disturbance playing time for: Fingerprint ≥10seconds

Black dot from 00:50 to 01:10

• jump forward/backward (search) within a reasonable time

2. CLEAN THE LENS

CD DRIVE – LENS CLEANING

Before touching the lens it is advised to clean the surface of the lens by blowing clean air over it in order to avoid that little particles make scratches on the lens.

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”, 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. It is advised to clean the lens gently (don’t press too hard) with a soft and clean cotton bud moistened with the special lens cleaner.

3. MEASURE THE LASER CURRENT

CD DRIVE – LASER CURRENT MEASUREMENT

The laser current can be measured as a voltage drop on resistor 3822. Typical value 55mV (DA11 disc drive).

If the value is higher than 80mV (DA11 disc drive) or the current increases just after switching the laser on - the laserdiode is most probably defective. In that case the CD drive has to be replaced.

4. GENERAL HINTS

Since the HF pre-amplifier is integrated into the new ”CD18“ signal processor the well-known eye pattern signal is not available as external signal and cannot be measured anymore. Also measuring the offset voltages is not necessary because the new signal processor contains an automatic offset compensation.

Universal Loader

(Single Disc Tray Loader)

This document describes the version with the Sanyo CD drive The CD drive used in a specific application is stated on the type plate, located on one of the side walls of the changer module.

The used sensitivity can be found out by either measuring the Monitor voltage or counting the up/down movements of the OPU until focus is found. e.g. when a normal CD DA is played back Monitor voltage should measure 150mV respectively Focus should be found within the first up/down movement of the OPU.

In case a higher sensitivity setting can be observed than defined, there are following possible reasons:

- disc scratched or dirty

- poor reflectivity of the disc - disc not conform standard

- lens of the OPU dirty

- laser power too low

Service hints

The following steps have to be done when replacing the CD mechanism:

1. Disconnect flexfoil cable from the old CD drive

2. Put a paperclip onto the flexfoil cable to short-circuit the contacts (fig.1)

3. Remove the old CD drive

4. Remove paperclip from the flexfoil cable and connect it to the new CD drive

5. Position the new CD drive on its studs

6. Remove solder joint from the Laser unit (see below)

CHARGED CAPACITORS ON THE SERVO BOARD MAY DAMAGE THE CD DRIVE ELECTRONICS WHEN CONNECTING A NEW CD MECHANISM.THAT´S WHY, BESIDES THE SAFETY MEASURES LIKE

• SWITCH OFF POWER SUPPLY

• ESD PROTECTION ADDITIONAL ACTIONS MUST BE TAKEN BY THE REPAIR TECHNICIAN.

fig.1

Attention: The laser diode of this CD drive is protected against ESD by a solder joint which short-circuits the

laser diode to ground. For proper functionality of the CD drive this solder joint must be removed after connecting the drive to the set.

Power 2003 Module

(75 - 150W Class D)

The oscillator frequency is created by 7312-3; it is a dual-frequency oscillator with ceramic resonators 5300 and 5302, which resonate at 500kHz and 425kHz respectively. The resonators are switched by transistors 7309 and 7316, controlled by the "OZ_SW" line from the port expander 7406. The reason for 2 frequencies is to avoid tuner disturbances in the AM-band. The oscillator signal is shaped to square wave with 7312-2, afterwards buffered and fed to the amplifier modulators (ROZ to the right channel, LOZ to the left). One channel gets inverted clock to balance supply loading.

• Modulator

The modulator forms the pulse width modulated signal. For each channel a seperate modulation is required.

• Power FETs

The FETs require drivers which supply the gates. One for the high-side-FET and one for the low-side-FET. Because of the different supply voltages also an additional level shifter is necessary per driver.

• Output filter

The output filter is necessary to block the 500kHz square wave signal from the speaker. Refers to the left channel in schematic diagrams. It consists of a series-mode coil 5101 and a capacity of approx. 550nF (2116, 2134), which forms a Chebycheff filter with 40kHz cut-off frequency at 6Ω load. For EMC reasons both, the speaker output and the return ground are fed through a common mode coil (5102).The filter is further improved by splitting the output capacity into 2116 before and 2134 after the common mode coil.

All above mentioned circuitries are located inside the metal shielding box.

Functional Description:

Refers to the left channel in schematic diagrams. The first stage of the modulator is an error integrator which compares the input to the (24 dB amplified) output signal of the 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 again integrating.The output signal leads to a triangle wave form (see oscillogram E).The DC value of this triangle signal is

floating, dependent on the amplitude of the analog input signal.The next stage is a comparator, which compares the integrated voltage with the internal switching levels - thus creating a voltage controlled duty cycle.7122 C and D improve the shape of the pulses.For details see oscillograms A-F. At pin 8 of IC7122 there is a square wave with the same frequency 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 by feeding the gate in respect to the source connection. Inverters 74LV14 are used as dr ivers. The driver for the lowside FET (7121) is supplied by the negative supply -VL2 and a voltage +VL (generated by 7115 and 6113), which is

7.5V higher than -VL2.The digital signal is level-shifted by 7128 to the low side driver stage.3142, 6111 and 2126 together form a delay circuit for rising edges by approx. 100ns for the low side FET. 3154, 6109 and 2137 delay the rising edge by 50ns for the high side FET. This to compensate the switch-off delay of the FETs and ensures that both FETs are not conducting at the same time. The high-side FET (7109) is controlled by the inverted signal taken from pin 2 of 7118, which is level-shifted by transistor 7119.The driver for the high-side FET is supplied by a floating voltage between the amplifier output -V1L and +V1L, created by the charge pump 6110, 2114 regulated by 7114 and 6114 to a 7.5V higher level.The pump is additionally supplied (via 3151) by +45V to ensure supply at start-up (no signal). The last stage in the gate driver consists of three gates in parallel for increased output current for the capacitive load of the FET. For additional increase of the switching speed push/pull transistors 7132/7111 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 is then sensed by 7104, the negative supply overcurrent triggers 7117, which then also triggers 7104. The collector current in turn triggers the monoflop 7122-5 and -6, giving a "High" pulse at pin 10.This shuts off level-shifter 7128 and blocks transistor 7129 and 7131, which draws current into the emitter resistor 3134 of level-shifter 7119.It is now also shut 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 is

done by pulling pin 13 of 7122 via signal line "AMP_OFF" and transistor 7130 to high level.The line "AMP_OFF" is controlled by the port expander 7406 which detects the headphone via signal line "HP_DET".

The loudspeakers are protected against DC voltages resulting e.g. from defective FETs.Voltages higher than ±2V are detected by 7110 respectively 7112.The transistors conduct and pull the "DC_PROT" line down, blocking transistor 7243 which in turn disables speaker relay 1201.

Adjustments:

The gain of the class-D amplifier is 24dB, adjusted by the feedback resistors 3155, 3136, 3149 and the input resistors 3139, 3340.The input reference voltage for 7122-A is approx. half the supply, therefore 3144, 3148 are used for offset compensation.This compensation has to be finetuned with trimpotentiometers 3306 and 3307 to obtain <1mV DC output.

Service Hints:

The analog part of the Combi Board can be repaired without opening the metal shielding box. In case of a ‘Class D’ problem it is advised to disassemble the board first, desolder the metal bottom cover of the shielding box and assemble 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 flow

2)Do not use de-solder wick

3)Simply hold the board upright down as shown in picture 1. Heat up solder joints and move tip of soldering iron slowly along the edge of the metal frame. Solder will flow along the soldering tip and rest on the metal plate. A small amount will drop off. A small gap will become visible as indication that the solder connection is released. When all solder joints are released the cover can be removed by help of a screwdriver. Begin at the cor ner indicated 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 that the arrow indicator on the cover is positioned in line with the arrow printed on the printed board → see picture 3.

2)Press the metal cover smoothly down until the gap between cover and printed board becomes a minimum. This is important for proper shielding.

3)Heat up the residual solder on the metal cover.The solder will flow back to the solder areas.If necessary apply additional new solder.

4)Take care that all solder joints are re-soldered again.

Attention: Poor soldering of the metal shielding box results

in disturbance of the tuner.

In most cases the FETs 7109 and/or 7121 for the left channel, respectively 7218 and/or 7231 for the right channel will be defective.This can easily be checked with an ordinary Ohm-meter.
