VA). Replace safety components, indicated by the symbol h, only by
components identical to the original ones. Any other component
substitution (other than original type) may increase risk of fire
or electrical shock hazard. Wear safety goggles when you replace
the CRT. Safety regulations require that after a repair, the set
must be returned in its original condition. Pay in 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 flows.
In particular this is valid for the: 1. Pins of the line output
transformer (LOT). 2. Fly-back capacitor(s). 3. S-correction
capacitor(s). 4. Line output transistor. 5. Pins of the connector
with wires to the deflection coil. 6. 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 Mains/AC Power lead for external damage. Check
the strain relief of the Mains/AC Power cord for proper function,
to prevent the cord from touching the CRT, hot components, or heat
sinks. Check the electrical DC resistance between the Mains/AC
Power plug and the secondary side (only for sets that have a
Mains/AC Power isolated power supply): 1. Unplug the Mains/AC Power
cord and connect a wire between the two pins of the Mains/AC Power
plug. 2. Set the Mains/AC Power switch to the "on" position (keep
the Mains/AC Power cord unplugged!). 3. Measure the resistance
value between the pins of the Mains/AC Power plug and the metal
shielding of the tuner or the aerial connection on the set. The
reading should be between 4.5 Mohm and 12 Mohm. 4. Switch "off" the
set, and remove the wire between the two pins of the Mains/AC Power
plug. Check the cabinet for defects, to prevent touching of any
inner parts by the customer.
2.3
Warnings 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 figure Discharge picture
tube, to discharge the picture tube. Use a high voltage probe and a
multi-meter (position VDC). Discharge until the meter reading is 0
V (after approx. 30 s).
V
E_06532_007.eps 250304
Figure 2-1 Discharge picture tube All ICs and many other
semiconductors are susceptible to electrostatic discharges (ESD w).
Careless handling during repair can reduce life drastically. Make
sure that, during repair, 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 same potential. Available ESD
protection equipment: Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable and earth cable) 4822 310 10671.
Wristband tester 4822 344 13999. Be careful during measurements in
the high voltage section. 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 prevents circuits from becoming unstable.
2.42.4.1
NotesGeneral Measure the voltages and waveforms with regard to
the chassis (= tuner) ground (H), or hot ground (I), depending on
the tested area of circuitry. The voltages and waveforms shown in
the diagrams are indicative. Measure them in the Service Default
Mode (see chapter 5) with a color bar signal and stereo sound (L: 3
kHz, R: 1 kHz unless stated otherwise) and picture carrier at
475.25 MHz for PAL, or 61.25 MHz for NTSC (channel 3). Where
necessary, measure the waveforms and voltages with (D) and without
(E) aerial signal. Measure the voltages in the power supply section
both in normal operation (G) and in stand-by (F). These values are
indicated by means of the appropriate symbols. The semiconductors
indicated in the circuit diagram and in the parts lists, are
interchangeable per position with the
2.2
Maintenance InstructionsWe recommend a maintenance inspection
carried out by qualified service personnel. The interval depends on
the usage conditions: When a customer uses the set under normal
circumstances, for example in a living room, the recommended
interval is three to five years. When a customer uses the set 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:

2.4.2
Schematic Notes All resistor values are in ohms, and the value
multiplier is often used to indicate the decimal point location
(e.g. 2K2 indicates 2.2 kohm). Resistor values with no multiplier
may be indicated with either an "E" or an "R" (e.g. 220E or 220R
indicates 220 ohm). All capacitor values are given in micro-farads
(= x10-6), nano-farads (n= x10-9), or pico-farads (p= x10-12).
Capacitor values may also use the value multiplier as the decimal
point indication (e.g. 2p2 indicates 2.2 pF). An "asterisk" (*)
indicates component usage varies. Refer to the diversity tables for
the correct values. The correct component values are listed in the
Spare Parts List. Therefore, always check this list when there is
any doubt.

lead-free logo (which is not always indicated), one must treat all
sets from this date onwards according to the rules as described
below.
2.4.3
Rework on BGA (Ball Grid Array) ICs General Although (LF)BGA
assembly yields are very high, there may still be a requirement for
component rework. By rework, we mean the process of removing the
component from the PWB and replacing it with a new component. If an
(LF)BGA is removed from a PWB, the solder balls of the component
are deformed drastically so the removed (LF)BGA has to be
discarded. Device Removal As is the case with any component that is
being removed, it is essential when removing an (LF)BGA, that the
board, tracks, solder lands, or surrounding components are not
damaged. To remove an (LF)BGA, the board must be uniformly heated
to a temperature close to the reflow soldering temperature. A
uniform temperature reduces the risk of warping the PWB. To do
this, we recommend that the board is heated until it is certain
that all the joints are molten. Then carefully pull the component
off the board with a vacuum nozzle. For the appropriate temperature
profiles, see the IC data sheet. Area Preparation When the
component has been removed, the vacant IC area must be cleaned
before replacing the (LF)BGA. Removing an IC often leaves varying
amounts of solder on the mounting lands. This excessive solder can
be removed with either a solder sucker or solder wick. The
remaining flux can be removed with a brush and cleaning agent.
After the board is properly cleaned and inspected, apply flux on
the solder lands and on the connection balls of the (LF)BGA. Note:
Do not apply solder paste, as this has been shown to result in
problems during re-soldering. Device Replacement The last step in
the repair process is to solder the new component on the board.
Ideally, the (LF)BGA should be aligned under a microscope or
magnifying glass. If this is not possible, try to align the (LF)BGA
with any board markers. So as not to damage neighboring components,
it may be necessary to reduce some temperatures and times. More

Figure 2-3 Lead-free logo Due to lead-free technology some rules
have to be respected by the workshop during a repair: Use only
lead-free soldering tin Philips SAC305 with order code 0622 149
00106. If lead-free solder paste is required, please contact the
manufacturer of your soldering 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 soldering tin. The solder tool must be able: To reach
a solder-tip temperature of at least 400C. To stabilize the
adjusted temperature at the solder-tip. To exchange solder-tips for
different applications. Adjust your solder tool so that a
temperature of around 360C - 380C is reached and stabilized at the
solder joint. Heating time of the solder-joint should not exceed ~
4 sec. Avoid temperatures above 400C, otherwise wear-out of tips
will increase drastically and flux-fluid will be destroyed. To
avoid wear-out of tips, switch off unused equipment or reduce heat.
Mix of lead-free soldering tin/parts with leaded soldering
tin/parts is possible but PHILIPS recommends strongly to avoid
mixed regimes. If this cannot be avoided, carefully clean the
solder-joint from old tin and re-solder with new tin. 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 lead-free BGA ICs: these ICs
will be delivered in so-called "dry-packaging" to protect the IC
against moisture. This packaging may only be opened shortly before
it is used (soldered). Otherwise the body of the IC gets "wet"
inside and during the heating time the structure of the IC will be
destroyed due to high (steam-) pressure inside the body. If the
packaging was opened before usage, the IC has to be heated up for
some hours (around 90C) for drying (think of ESD-protection!). Do
not re-use BGAs at all!
Safety Instructions, Warnings, and Notes For sets produced
before 1.1.2005, containing leaded soldering tin and components,
all needed spare parts will be available till the end of the
service period. For the repair of such sets nothing changes.

In case of doubt whether the board is lead-free or not (or with
mixed technologies), you can use the following method: Always use
the highest temperature to solder, when using SAC305 (see also
instructions below). De-solder thoroughly (clean solder joints to
avoid mix of two alloys). Caution: For BGA-ICs, you must use the
correct temperatureprofile, which is coupled to the 12NC. For an
overview of these profiles, visit the website
www.atyourservice.ce.philips.com (needs subscription, but is not
available for all regions) You will find this and more technical
information within the "Magazine", chapter "Repair downloads". For
additional questions please contact your local repair help desk.
2.4.5 Alternative BOM identification In September 2003, Philips CE
introduced a change in the way the serial number (or production
number, see Figure 2-1) is composed. From this date on, the third
digit in the serial number (example: AG2B0335000001) indicates the
number of the alternative BOM (Bill of Materials used for producing
the specific model of TV set). It is possible that the same TV
model on the market is produced with e.g. two different types of
displays, coming from two different O.E.M.s. By looking at the
third digit of the serial number, the service technician can see if
there is more than one type of B.O.M. used in the production of the
TV set he is working with. He can then consult the At Your Service
Web site, where he can type in the Commercial Type Version Number
of the TV set (e.g. 28PW9515/12), after which a screen will appear
that gives information about the number of alternative B.O.M.s
used. If the third digit of the serial number contains the number 1
(example: AG1B033500001), then there is only one B.O.M. version of
the TV set on the market. If the third digit is a 2 (example:
AG2B0335000001), then there are two different B.O.M.s. Information
about this is important for ordering the correct spare parts! For
the third digit, the numbers 1...9 and the characters A...Z can be
used, so in total: 9 plus 26 = 35 different B.O.M.s can be
indicated by the third digit of the serial number. 2.4.6 Practical
Service Precautions It makes sense to avoid exposure to electrical
shock. While some sources are expected to have a possible dangerous
impact, others of quite high potential are of limited current and
are sometimes held in less regard. Always respect voltages. While
some may not be dangerous in themselves, they can cause unexpected
reactions that are best avoided. Before reaching into a powered TV
set, it is best to test the high voltage insulation. It is easy to
do, and is a good service precaution.

Adjust the AGC data in Factory Mode in such a way the noise just
disappears. 3. Change the signal to 90dB. 4. Measure the voltage at
test Pin C of Q101 (this is the PreAmplifier output). 5. Write down
this voltage, and call it V1P-P. 6. Apply an 8-scale gray signal
with Color Bar (90Db) 7. Adjust the AGC data in Factory Mode in
such a way the picture is without distortion and interference. 8.
Change the signal to 8-scale gray signal (90dB). 9. Measure the
voltage at test Pin C of Q101 (Pre-Amplifier output) 10. Write down
this voltage and call it V2P-P. 11. Calculate the value VP-P with
the following formula: VPP={(V2P-P)-(V1P-P)}/3.
12. Apply 8-scale gray signal (90dB). 13. Measure the voltage at
test Pin C of Q101 (Pre-Amplifier output) 14. Adjust AGC data until
the voltage of Pin C of Q101 reaches the value of VP-P

Brief Introduction of the ChassisChassis block diagram
G_16340_010.eps 100306
Figure 9-1 Chassis block diagram 9.1.2 Power Supply Section This
section mainly consists of IC STR-W6735 (IC801). Transformer
(T803). Bridge rectifier (DB801). Accessory circuits. The supply
voltage for this chassis should be AC 110V. The allowed voltage
range is 90V to 140V, the frequency range is 50/60Hz. The AC power
with high/low frequency interference goes through an RC filter,
consisting of C801, T801, C802, R801, and T802. The filter removes
the high/low frequency interference. Then DB801 transforms the AC
power to DC power. T803 and IC 801 work in standby state. T803 will
provide a power voltage to IC101. IC101 scans for the "KEY IN"
signal (Pin 3 of IC101) from the ON/OFF switch on the keyboard. If
"KEY IN" = "power on" signal, pin 64 (IC101) will generate a signal
to drive the photo coupler (IC8021). It acts as a feed back circuit
(feed back to Pin 6 of IC801) for controlling IC801 to adjust
MOSFET. Transformer T803 provides the following voltages: +13V
voltage from Pin16. +130V (B+) voltage from Pin1. +12V from Pin 15.
Pin 15 is also connected to two Positive Voltage Regulators (IC201,
IC202) in-series. The outputs of these regulators are +9V and +5V
respectively. The picture below shows IC201 and IC202:

Figure 9-3 Pre-amplifier circuit 9.1.4 Sound Process Section The
SIF signal is sent out together with the TV signal from Pin30 of
IC101. It passes through Q203, R225. X202 and a High-pass filter
(consisting of C254, L206, C253) filters out the video signal and
low frequency interference.

From Pin58 of IC101 the I2C bus clock signal goes to the tuner.
The tuner works during the clock time. IC101 will send out a data
signal from Pin57 to control the tuner's working state by
controlling the +33V voltage. +33V is provided from Pin10 of T803.
That voltage is put into the tuner at Pin7. A circuit inside the
tuner transforms +33V into a voltage between 0 and +33V (as a
function of the data, sent by IC101). The AGC signal is a close
loop control voltage that keeps the amplitude of the signal
constant. Output of tuner is the Intermediate Frequency signal (IF
signal). The IF signal will pass pre-amplifier circuit (refer to
the picture below). The amplified IF signal passes the SAW filter
and is then sent to IC101 Pin41/42. IC101 creates a CVBS signal and
sends it out from Pin30. CVBS will be selected by IC901, and then
pass from Pin13 of IC901 to Pin20/24 if IC101. IC101 will
demodulate the CVBS signal into an R, G, B signal. Next IC101 will
send this R, G, B signal from Pin50/51/52 to the CRT board.
Figure 9-4 Sound process section 1 SIF will be finally sent into
Pin2 of IC1001. An analog automatic gain control circuit (AGC)
allows a wide range of input levels. The analog-to-digital
conversion of the IF sound signal is done by an A/D-converter. The
high pass filter, formed by a coupling capacitor at SIF_IN1+
suppresses video components. IC1001 is controlled via the I2C bus
slave interface. The AV sound signal will be directly sent to
Pin37/38 or Pin40/ 41 of IC1001. Q901/2 and Q903/4 form
Emitter-Follower circuits to provide a better load ability. The
(analog) sound signal will go from Pin26/27 of IC1001 to Pin4/12 of
IC602. IC602 is a dual bridge amplifier. The output voltage of
IC602 drives the speakers. The volume is adjusted via the I2C
bus.

Vertical Output Section This section mainly consists of IC301
(TDA8172), the Vertical Coil and the related circuit. The supply
voltage of IC301 are +14V and -14V. These two voltages are provided
by the LOT section. For the vertical scan, IC101 creates a
Saw-tooth waveform at Pin16. This is the input signal of IC301. The
main task of IC101 is to create the vertical scan waveform. The
output signal of IC301 drives the Vertical Coil. If IC301 works in
normal state, Pin6 will send a square-signal to maintain a high
voltage at D214. If it does not, D214 will get a low voltage, Pin2
of IC101 senses this change and IC101 sends out a standby
signal.
9.1.6
Horizontal Output and LOT Section The horizontal drive pulse is
a square wave. IC101 creates this waveform at Pin13. Via Q401 the
signal goes to the input of Q411. Q411 is a horizontal output
triode with a damper inside. The signal from Pin C of Q411 drives
the Horizontal Coil. When Q411 goes into cut-off state, a sub-coil
inside the LOT will generate an EHT by inductance.
