Safety & Maintenance Instructions, Warnings, and Notes

2. Safety & Maintenance Instructions, Warnings, and Notes

2.1 Safety Instructions For Repairs

2.1.1 General Safety

Safety regulations require that during a repair

• Due to the ‘hot’ parts of this chassis, the set must be

connected to the AC power via an isolation transformer.

• Safety components, indicated by the symbol , should be

replaced by components identical to the original ones.

• When replacing the CRT, safety goggles must be worn.
Safety regulations require that after a repair, the set must be
returned in its original condition. Pay particular attention to the
following points:

• General repair instruction: as a strict precaution, We advise

you to re-solder the solder connections through which the
horizontal deflection current is flowing, in particular:
– all pins of the line output transformer(LOT)
– fly-back capacitor(s)
– S-correction capacitor(s)
– line output transistor
– pins of the connector with wires tothe deflection

coil

– other components through which the deflection current

flows.
Note: This re-soldering is advised to prevent bad connections
due to metal fatigue in solder connections and is therefore only
necessary for television sets more than two years old.

• Route the wire trees and EHT cable correctly and secure

them with the mounted cable clamps.

• Check the insulation of the AC power cord for external

damage.

• Check the strain relief of the AC power cord for for proper

function, to prevent the cord from touching the CRT, hot
components,or heat sink.

• Check the electrical DC resistance between the AC plug

and the secondary side (only for sets that have an isolated
power supply). Do this as follows:

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

2. Turn on the main power switch (keep the AC power
cord unplugged)

3. Measure the resistance value between the pins of the
AC plug and the metal shielding of the tuner or the
aerial connection of the set. The reading should be
between 4 M and 8 M.

4. Switch the TV OFF and remove the wire between two
pins of the AC plug.

• Check the cabinet for defects, to prevent the the possibility
of the customer touching any internal parts.

Figure 2-1 Class 1 Laser Product

Note: Use of controls or adjustments or performance of

procedure other than those specified herein, may result in
hazardous radiation exposure. Avoid direct exposure to beam.

2. 1.3 Sh ock , F ire Hazar d Serv ice Te st

Caution: After servicing this appliance and prior to returning to

customer, measure the resistance between either primary AC
cord connector pins (with unit NOT connected to AC mains and
its Power switch ON), and the face or Front panel of the
product and controls and chassis bottom.
Any resistance measurement less than 1 Megohms should
cause unit to be repaired or corrected before AC power is
applied, and verified before return to user/customer. Ref. UL
Standard NO. 1492
Note on safety:
Symbol : Fire or electrical shock hazard. Only original parts
should be used to replace any part with symbol  (other than
original type), may increase risk or fire or electrical shock
hazard.

2. 2 2. 2 Ma i n te n a nc e I n st r u cti o n s

It is recommended to have a maintenance inspection carried
out by qualified service personnel. The interval depends on the
usage conditions:

• When the set is used under normal circumstances, for
example in a living room, the recommended interval is
three to five years.

• When the set is used in an environment with higher dust,
grease or moisture levels, for example in a kitchen, the
recommended interval is one year.

• The maintenance inspection includes the following actions:

1. Perform the 'general repair instruction' noted above.

2. Clean the power supply and deflection circuitry on the

chassis.

3. Clean the picture tube panel and the neck of the picture

Tube.

2.3 Warnings

2.1.2 2.1.2 Laser Safety

This unit employs a laser .Only qualified service personel
remove the cover, or attempt to service this device (duo to
possible eye injury).

Laser Device Unit

Type : semiconductor laser

GaA/As
Wavelength : 650 nm (DVD)
: 780 nm (VCD/CD)
Output Power : 7 mW (DVD)
: 10 mW (VCD/DVD)
Beam divergence : 60 degree

2.3.1 2.3.1 General

• In order to prevent damage to ICs and transistors, avoid all
high voltage flashovers. In order to prevent damage to the
picture tube, use the method shown in Fig. 2-1, to dischage
the picture tube. Use a high voltage probe and a multi­meter (position VDC). Discharge until the meter reading is
0 V (after approx. 30 s).

Safety & Maintenance Instructions, Warnings, and Notes

Figure 2-2

• All ICs and many other semiconductors 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 by a wristband with resistance. Keep
components and tools also at this potential. Available ESD
protection equipment:
– Complete kit ESD3 (small tablemat, wristband,

connection box, extension cable, and ground cable)
4822 310 10671.

– Wristband tester 4822 344 13999.

• Together with the deflection unit and any multi-pole unit.
flat square picture tubes form an integrated unit. The
deflection and the multi-pole units are set optimally at the
factory. Adjustment of this unit during repair is therefore not
recommended.

• Be careful during measurements in the high voltage
sect i o n sec t i on an d o n the p i c ture t u be.

• Never replace modules or other components while the unit
is switched ON.

• When you align the set, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a
circuit becoming unstable.

EN 5TC4.1U AA 2.

• Where necessary, measure the waveforms and voltages
with ( ) and without (  ) aerial signal. Measure the
voltages in the power supply section both in normal
operation (  ) and in standby (  ). These values are
indicated by means of the appropriate symbols.

• The picture tube panel has printed spark gaps. Each spark
gap is connected between an electrode of the picture tube
and the Aquadag coating.

• The semiconductors indicated in the circuit diagram and in
the parts lists are completely interchangeable per position
with the semiconductors in the unit, irrespective of the type
indication on these semiconductors.

2.3.2 Laser

• The use of optical instruments with this product, will
increase eye hazard.

• Only qualified service personnel may remove the cover or
attempt to service this device, due to possible eye injury.

• Repair handling should take place as much as possible
with a disc loaded inside the player.

• Text below is placed inside the unit, on the laser cover
shield.

5.1 Compair

5.1.1 Introduction

ComPair (Computer Aided Repair) is a service tool for Philips
Consumer Electronics products. ComPair is a further
development on the European DST (service remote
control),which allows faster and more accurate diagnostics.
Compare has three big advantages: .

• ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you
systematically through the repair procedures.

• ComPair allows very detailed diagnostics (on I2C level)
and is therefore capable of accurately indicating problem
areas. You do not have to know anything about I2C
commands yourself because ComPair takes care of this.

• ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the
microprocessor is working) and all repair information is
directly available. When ComPair is installed together with
the SearchMan electronic manual of the defective chassis,
schematics and PWBs are only a mouse click away.

5.1.2 Specifications

ComPair consists of a Windows based faultfinding program
and an interface box between PC and the (defective) product.
The ComPair interface box is connected to the PC via a serial
or RS232 cable.
In case of the M133 chassis, the ComPair interface box and the
TV communicate via a bi-directional service cable via the
service connector.
The ComPair faultfinding program is able to determine the
problem of the defective television. ComPair can gather
diagnostic information in two ways:

• Automatic (by communication with the
television):ComPair can automatically read out the
contents of the entire error buffer. Diagnosis is done on I2C
level. Compare can access the I2C bus of the television.
ComPair can send and receive I2C commands to the micro
controller of the television. In this way, it is possible for
ComPair to ommunicate (read and write) to devices on the
I2C busses of the TV-set.

• Manually (by asking questions to you): Automatic
diagnosis is only possible if the micro controller of the
television is working correctly and only to a certain extend.
When this is not the case, ComPair will guide you through
the faultfinding tree by asking you questions (example:
Does the screen give a picture? Click on the correct
answer: YES / NO) and showing you examples (example:
Measure P202 and click on the correct oscillogram you see
on the oscilloscope). You can answer by clicking on a link
(e.g. text or a waveform picture) that will bring you to the
next step in the faultfinding process.

• By a combination of automatic diagnostics and an
interactive question / answer procedure, ComPair will
enable you to find most problems in a fast and effective
way.

• Beside fault finding, ComPair provides some additional
features like:

• Up or downloading of presets.

• Managing of preset lists.

• If both ComPair and SearchMan (Electronic Service
Manual) are installed, all the schematics and the PWBs of
the set are available by clicking on the appropriate
hyperlink.

5.1.3 How To Connect

First install the ComPair Browser software before connecting
ComPair to the M133-DVD (see the Quick Reference Card for
installation instructions). In the M133-DVD, you can only
diagnose the TV. Always start the diagnosis by connecting the
ComPair tool to the TV-set. Connection to the TV-set.

1. Connect the RS232 interface cable between a free serial
(COM) port of your PC and the PC connector (marked with
'PC') of the ComPair interface.

2. Connect the mains adapter to the supply connector
(marked with 'POWER 9V DC') on the ComPair interface.

3. Switch the ComPair interface "off".

4. Switch the television set "off" with the mains switch.

5. Connect the ComPair interface cable (3122 785 90004)
between the connector on the rear side of the Compare
interface (marked with 'I2C') and the ComPair connector
P202 on the mono carrier.

PC VCR Power I2C

Figure 5-1 ComPair set-up

1. Plug the mains adapter in the mains outlet and switch "on"
the interface. The green and red LEDs light up together.
The red LED extinguishes after approx. 1 second while the
green LED remains lit.

2. Start the ComPair program and read the 'introduction'
chapter.

Connection to the DVD-module

Follow the instructions given on the screen for further
diagnosis.

1. Use the ComPair DVD interface cable (3122 785 90017) to
connect the DVD-module to the ComPair interface.

• ComPair interface cable for TV set: 3122 785 90004.

5.2 Error Codes

5.2.1 Error Buffer

The error code buffer contains all detected errors since the last
time the buffer was erased. The buffer is written from left to
right. When an error occurs that is not yet in the error code
buffer, it is written at the left side and all other errors shift one
position to the right.

EN 33TC4.1U AA 5.

5.2.2 Error Codes

In case of non-intermittent faults, clear the error buffer before
you begin the repair. These to ensure that old error codes are
no longer present.

If possible, check the entire contents of the error buffer. In
some situations an error code is only the result of another error
code and not the actual cause (e.g., a fault in the protection
detection circuitry can also lead to a protection).

9.2 Audio Signal Processing

Stereo

In stereo sets, the signal goes via the SAW filter (position
Z10A), to the audio demodulator part of the UOC IC101. The
audio output on pin 31 goes to the stereo decoder IC1001.The

Figure 9-1 Block Diagram

switch inside this IC selects either the internal decoder or an
external source (see also block diagram above).
The built-in stereo decoder item IC1001 (MSP3425G) can
receive 2CS, NICAM and BTSC stereo signals.The output is
fed ic601 to the audio amplifier (TDA7496 at position IC601).
The volume level is controlled at this IC (pin 10 ) by a 'Mute'

EN 66 TC4.1U AA9.

Circuit Description

control line from the microprocessor. The audio signal from
IC601 is then send to the speaker and headphone output
panel.

9.3 Video Signal Processing

9.3.1 Introduction

The video signal-processing path consists of the following
parts:

• RF signal processing.

• Video source selection.

• Video demodulation.

• Luminance/Chrominance signal processing

• RGB amplifier
The processing circuits listed above are all integrated in the
UOC TV processor. The surrounding components are for the
adaptation of the selected application. The I2C bus is for
defining and controlling the signals.

9.3.2 RF Signal Processing

The incoming RF signal goes to the tuner (pos. TU101), where
the IF signal is developed and amplified. The IF signals then
exits the tuner from pin 11 to pass through the SAW filter (pos.
Z101). The shaped signal is then applied to the IF processor
part of the UOC (pos. IC101).
Tuner AGC (Automatic Gain Control) will reduce the tuner gain
and thus the tuner output voltage when receiving strong RF
signals. Adjust the AGC takeover point via the Service
DefaultAlignment Mode (SDAM). The tuner AGC starts working
when the video-IF input reaches a certain input level and will
adjust this level via the I2C bus. The tuner AGC signal goes to
the tuner (pin 1) via the open collector output (pin 43) of the
UOC.The IC also generates an Automatic Frequency Control
(AFC) signal that goes to the tuning system via the I2C bus, to
provide frequency correction when needed.
The demodulated composite video signal is available at pin 30
and then buffered by transistor Q203.

9.3.3 Video Source Selection

The Composite Video Blanking Signal (CVBS) from buffer
Q201 goes to the audio carrier trap filters 1200, 1201, or 1202
(depending on the system used), to remove the audio
signal.The signal then goes to pin 26 of IC 101. The internal
input switch selects the following input signals:

• Pin 26: terrestrial CVBS input

• Pin 24: external AV1 CVBS input

• Pin 19,20,21: external DVD YUV signal input
Once the signal source is selected, a chroma filter calibration is
performed. The received color burst sub-carrier frequency is
used for this. Correspondingly, the chroma band pass filter for
PAL/NTSC processing is switched on. The selected luminance
(Y) signal is supplied to the horizontal and vertical
synchronization circuit and to the luminance processing circuit.
In the luminanceprocessing block, the luminance signal goes to
the chroma trap filter. This trap is switched 'on' or 'off'
depending on the color burst detection of the chroma
cal bration circuit.
The group delay correction part can be switched between the
BG and a flat group delay characteristic. This has the
advantage that in multi-standard receivers no compromise has
to be made for the choice of the SAW filter.

and not affected by the content of the video signal. The tuner
features stable receptivity while the signal output from the
video detector features high fidelity.
PLL built-in PMPA8823 generates 45.75MHZ demodulation
reference signal for Sync detector to demodulate the video
signal, which is called ‘PLL Sync demodulation’.

9.3.5 Chrominance signal Processing

Through the external BPF(band-pass filter) to single out the
chroma signal and burst signal within the range of Fsc
+1.3MHZ from among the composite signals output from the
video detector. After being amplified by ACC, the chroma
signal is fed into the synchronous detector to be demodulated
to obtain the color difference signal.

9.3.6 Luminance channel and matrix circuit

The luminance channel of TMPA8823 has the black strech
circuit to make the ‘darkish’ ingredient of the picture turn
‘atrous’, thus improve the contrast and depth perception of the
picture . It also has the delayed definition-enhanced circirt to
enable the details of the picture more vivid. The luminance
signal(Y) is sent into the matrix circuit after being delayed for

0.6s and composed R/G/B signal combined with three color­difference signals(B-Y,R-Y,B-Y).

9.3.7 CRT Drive Circuit

Adopting the cascode to amplify voltage and current of R/G/B
signal ,the CRTdrive circuit is able to demodulate the cathode
beam current of the CRT. The R/G/B signal input into the
cascode circuit is of negative polarity.

9.4 Sync Separation and Deflection Processing
Circuit

TMPA8823 has the 32fh PLL (fh = horizontal frequency). In
accordance with the frequency and phase information carried
by composite sync signal, PLL generates scan clock signal with
32fh and horizontal drive pulse will be obtained through 32fh
countdown. Use integrating circuit to extract vertical sync
signal from the composite sync pulse to control the counter for
vertical countdown. The counter countdown the 32fh clock
signal, thus vertical frequency sync pulses under various
systems can be obtained.
TMPA8823 includes the vertical SW former(sawtooth wave
former) and control the gain and linear of SW(sawtooth wave).
Therefore, the vertical amplitude control and the linearity
correction of the scanning raster can be achieved by setting the
data with remote controller via I2C bus input.

9.3.4 Video Demodulation

The IF channel mainly ensures the sensitivity and selectivity of
the complete machine. The IF AMP integrated in TMPA8823 is
made up of the third-stage dual-differential amplifier with gain
value above 70dB, SNR of 55Db and bandwidth of 6MHZ. The
video demodulation circuit is made from the built-in PLL Sync
detector. The spectrum of the demodulation carrier is unitary

9.5 Power Supply

Circuit Description

EN 67TC4.1U AA 9.

Figure 9-2 Figure 9-2 Internal block diagram of the driver IC (TDA16846)

9.5.1 Introduction

The supply is a Switching Mode Power Supply (SMPS). The
frequency of operation varies with the circuit load. The power
supply starts operating when a DC voltage goes from the
rectifier circuit (D810-D804) via T803, R812 to pin 14. The
operating voltage for the driver circuit is also taken from the
'hot' side of this transformer.
The switching regulator IC 801 starts switching the FET (Q801)
'on' and 'off', to control the current flow through the primary
winding of transformer T803. The energy stored in the primary
winding during the 'on' time is delivered to the secondary
windings during the 'off' time.

The 'MainSupply' line is the reference voltage for the power
supply. It is sampled by resistors R840, VR821 and R841 ,
regulator IC803 can get different output by adjusting VR821.
This regulator drives the feedback opto-coupler IC802 to set
the feedback control voltage on pin 5 of IC801.
The power supply in the set is 'on' any time AC power goes to
the set.

Derived Voltages

The voltages supplied by the secondary windings of T5520 are:

• +24V derived from pin 10 of T803 and +12V derived from
pin 16 of T803 are for the audio circuit

EN 68 TC4.1U AA9.

• +12V derived from pin 12 of T803 ,-14V derived from pin 4
of LOT T402 and +5V derived from pin 13 of T803 are for
the DVD module

• 'MainSupply' for the horizontal output, +33V for tuning
system is the secondary output of Mainsupply

• +9V is the secondary output of +12V, +5V is derived from
+9V by regulator IC103, these two voltages are for
UOC,signal processing circuit .

Other supply voltages are provided by the LOT. It supplies
+14V and -14V for the Frame deflection circuit, +200 V source
for the video drive. The secondary voltages of the LOT are
monitored by the 'EHT information' lines. These lines are fed to
the video processor part of the UOC IC 101 on pins 2 and 27.
This circuit will shut 'off' the horizontal drive in case of
overvoltage or excessive beam current.

9.5.2 Basic IC Functionality Description

The TDA 16846 is optimized to control free running or fixed
frequency flyback converters with or without Power Factor
Correction (Current Pump). To provide low power consumption
at light loads, this device reduces the switching frequency
continuously
with load, towards an adjustable minimum (e. g. 20 kHz in
standby mode). Additionally, the start up current is very low. To
avoid switching stresses of the power devices, the power
transistor is always switched on at minimum voltage. A special
circuit is implemented to avoid jitter. The device has several
protection functions: VCC over- and undervoltage, mains
undervoltage, current limiting and 2 free usable fault
comparators. Regulation can be done by using the internal
error amplifier or an opto coupler feedback (additional input).
The output driver is ideally suited for driving a power MOSFET,
but it can also be used for a bipolar transistor. Fixed frequency
and synchronized operation are also possible.
The TDA 16846 is suited for TV-, VCR- sets and SAT receivers.
It also can be good used in PC monitors.

Start Up Behaviour (Pin 14)

When power is applied to the chip and the voltage V14 at Pin
14 (VCC) is less than the upper threshold (VON) of the Supply
Voltage Comparator (SVC), input current I14 will be less than
100 mA. The chip is not active and driver output (Pin 13) and
control output
(Pin 4) will be actively held low. When V14 exceeds the upper
SVC threshold (VON) the chip starts working and I14
increases. When V14 falls below the lower SVC threshold
(VOFF) the chip starts again at his initial condition. Figure 9-3
shows the start-up circuit and Figure9-4 shows the voltage
V14 during start up. Charging of C14 is done by resistor R2 of
the “Primary Current Simulation” (see later) and the internal
diode D1, so no additional start up resistor is needed. The
capacitor C14 delivers the supply current until the auxiliary
winding of the transformer supplies the chip with current
through the external diode D14.

For proper operation of the special internal anti jitter circuit,
TC1 should have the same value as the resonance time “TR”
of the power circuit (Figure 9-6). After charging C1 up to 3.5 V

resistor R1. The voltage

9.5.3 Protection Functions

The chip has several protection functions:

Current Limiting

See “Primary Current Simulation PCS (Pin 2) / Current
Limiting” and “Fold Back Point Correction PVC (Pin 11)”.

Over- and Undervoltage Lockout OV/SVC (Pin 14)

When V14 at Pin 14 exceeds 16 V, e. g. due to a fault in the
regulation circuit, the ErrorFlip Flop ERR is set and the output
driver is shut-down. When V14 goes below the lower SVC
threshold, ERR is reset and the driver output (Pin 13) and the
soft-start (Pin 4) are
shut down and actively held low.

Primary Voltage Check PVC (Pin 11)

When the voltage V11 at Pin 11 goes below 1 V the Error Flip
Flop (ERR) is set. E.g. a voltage divider from the rectified mains
at Pin 11 prevents from high input currents at too low input
voltage.

Free Usable Fault Comparator FC1 (Pin 10)

When the voltage at Pin 10 exceeds 1 V, the Error Flip Flop
(ERR) is set. This can be used e. g. for mains overvoltage
shutdown.

Free Usable Fault Comparator FC2 (Pin 6)

When the voltage at Pin 6 exceeds 1.2 V, the Error Flip Flop
(ERR) is set. A resistor between Pin 9 (REF) and ground is
necessary to enable this fault comparator.

Voltage dependent Ringing Suppression Time

During start-up and short-circuit operation, the output voltage
of the converter is low and parasitic zero crossings are applied
for a longer time at Pin 3. Therefore the Ringing Suppression
Time TC1 (see “Off-Time Circuit OTC (Pin 1)”) is made longer
with factor 2.5 at low output voltage. To ensure start-up of the
circuit, the value of resistor R1 (Pin 1, Figure 9-5) must be
higher than 20 kW.

9.6 Control

Circuit Description

EN 71TC4.1U AA 9.

9.6.1 Introduction

The microprocessor part of the UOC, has the complete control
on board. User menu, Service Default Mode, Service
Alignment Mode and Customer Service Mode are generated by
the uP. Communication to other ICs is done via the I2C-bus.

9.6.2 I2C-Bus

The main control system, which consists of the microprocessor
part of the UOC (IC101), is linked to the external devices (tuner,
NVM, MSP, etc) by means of the I2C-bus. An internal I2C-bus
is used to control other signal processing functions, like video
processing, sound IF, vision IF, synchronization, etc.

9.6.3 User Interface

The M133 uses a remote control with RC5 protocol. The
incoming signal is connected to pin 63 of the UOC.
The 'Top Control' keyboard, connected to UOC pin 3, can also
control the set. Button recognition is done via a voltage divider.
The front LED (D401) is connected to an output control line of
the microprocessor (pin 56). It is activated to provide the user
information about whether or not the set is working correctly
(e.g., responding to the remote control, normal operation (USA
only) or fault condition)

9.6.4 In- and Output Selection

For the control of the input and output selections, there are
three lines:
STATUS1. In the TV mode, it outputs TV signal, including
VIDEO and AUDIO signal.
STATUS2. In the AV mode, it outputs AV signal, including
VIDEO and AUDIO signal.
STATUS3. In the DVD mode, it outputs DVD signal, including
VIDEO and AUDIO signal.

9.6.5 Power Supply Control

The microprocessor part is supplied with 5V derived from the
'MainAux' voltage via a 5V stabilizer (D817) and a diode.Two
signals are used to control the power supply:

Figure 9-13 lock diagram set control

Stdby_con. This signal is generated by the microprocessor

when over-current takes place at the 'MainAux' line. This is
done to enable the power supply into standby burst mode, and
to enable this mode during a protection. This signal is 'low'
under normal operation conditions and goes to 'high' (5V)
under 'standby' and 'fault' conditions.
POWER_DOWN. This signal is generated by the power
supply. Under normal operating conditions, this signal is 'high'
(5 V). During 'standby' mode, this signal is a pulse train of
approx. 10 Hz and a 'high' duration of 5 ms. It is used to give
information to the UOC about the fault condition in the Audio
amplifier supply circuit. This information is generated by
sensing the current on the 'MainAux' line (using voltage drop
across R249 to trigger Q207). This signal goes 'low' when the
DC-current on the 'MainAux' line exceeds 1.6 - 2.0 A. It is also
used to give an early warning to the UOC about a power failure.
Then the information is used to mute the sound amplifier to
prevent a switch off noise and to solve the switch-off spot.

9.6.6 Protection Events

Several protection events are controlled by the UOC:
BC protection, to protect the picture tube from a too high beam
current. The UOC has the capability of measuring the normal
back level current during the vertical flyback. Soif for some
reason the CRT circuit is malfunctioning (i.e. high beam
current), the normal black current will be out of the 75 A range,
and the UOC will trigger the power supply to shut down.
However, this is a high beam-current situation, the TV screen
will be bright white before the set is shut down.
I2C protection, to check whether all I2C ICs are functioning.
In case one of these protections is activated, the set will go into
'standby'.
The 'on' and 'standby' LEDs are controlled via the UOC.
