Safety Instructions, Warnings, and Notes
2.Safety Instructions, Warnings, and Notes
Index of this chapter:
2.1 Safety Instructions
2.2 Maintenance Instructions
2.3 Warnings
2.4 Notes
2.1Safety Instructions
Safety regulations require the following during a repair:
•Connect the set to the Mains/AC Power via an isolation
transformer (> 800 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.
2.2Maintenance Instructions
We 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:
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.
2.3Warnings
•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 V
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.
•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.
2.4Notes
2.4.1General
•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 colour 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
semiconductors in the unit, irrespective of the type
indication on these semiconductors.

2.4.2Schematic 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 (μ= x10
nano-farads (n= x10
•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.
2.4.3Lead-free Soldering
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 400°C.
– 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
360°C - 380°C 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 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
-9
), or pico-farads (p= x10
-12
avoid mixed regimes. If this cannot be avoided, carefully
clear the solder-joint from old tin and re-solder with new tin.
2.4.4Alternative BOM identification
In September 2003, Philips CE introduced a change in the way
the serial number (or production number, see Figure 2-2) is
-6
),
).
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.
2.4.5Practical 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.

Waveforms".
Perform measurements under the following conditions:
•Service Default Mode.
•Video: colour bar signal.
•Audio: 3 kHz left, 1 kHz right.
5.2Ser vice Modes
This chassis does not contain a specific Service Mode. Service
and Alignment of the TV set can be done via the Factory Mode
by the service technician, see further down in this manual.
5.3Error Codes
Not applicable.
5.4.6Picture not or incorrect Coloured
•Check the circuit from IC201 to R.G.B. three gun circuit.
•Check the IC soldering and relevant circuitry on physical
damage or check for defective capacitors.
5.4.7Picture with Horizontal Bright Line and Sound
Check both supply voltages of vertical IC301 and relevant
circuitry on correctness. Also check the vertical synchronizing
signal from IC201.
5.4.8Remote Control Malfunction
Check the voltage on pin 64 of IC201. The normal value should
be 5.15 V. If this is correct check front control panels soldering
connections. If can't be solved, check the remote control,
crystal or transmitting diode of the remote control are in good
condition.
5.4.9No Sound
Check power supply of sound IC (IC402) and relevant circuitry.
Check as well the BTSC board, check the power supply of
IC801 and relevant output signal pins 21 and 27 of this IC. Do
not exclude IC801 and/or IC402 to be defective. If needed
replace the speakers.
5.4Fault Finding
5.4.1 Power on Failure
Check whether the power supply is working properly and
whether the values of voltages normal. If those are correct,
check line transistor and transformer are working properly or
check fore or back line for defects.
5.4.2Horizontal Deflection Transistor Defective: No Picture, No
Sound.
To find the fault for a defect horizontal deflection transistor
please check the following items:
•Over voltage to breakdown.
•Over current to burn.
•Horizontal frequency too low.
•Horizontal drive inefficient.
5.4.3Picture Interference
•Check if the signal line contact is good.
•Change Tuner if is necessary.
5.4.4Can't find any TV program
Checking method: Check the closed circuit from tuner to
picture decoder IC to detect whether there are defective
components. Or check whether the resistance of R117, R118,
R203 and R204 has increased which also could cause the
problem.
5.4.10 Poor Sound Quality
Check the sound system after searching the channel which
should set at NTSC or AUTO. If still has problem, check
accompany board circuit on chassis good or not.
5.4.5No Good Picture or Double Image
Check the correctness of the signal from IF1/IF2 to Q101 and
relevant circuit. In this case the problem can be Q101 and/or
SAW101.

9.1Introduction
The SK5.0L CA is a CRT TV for the year 2007, based on the
5P19 platform. In this chapter, only a general description of the
various circuits is given. For more detailed information, see the
circuit diagrams in this manual.
9.2The various circuits
9.2.1Tuner
The function of the tuner is to select the channel to be received
and suppress the interference of neighboring channels, to
amplify the high frequency signal, to improve the receiving
sensitivity and SNR, and to generate a PIF signal through
frequency conversion.
9.2.2IF Channel
The IF Channel mainly ensures the sensitivity and selectivity of
the complete TV set. The IF AMP integrated in the UOCIII is
made up of a three-stage dual-differential amplifier with a gain
value above 70dB, a SNR of 55dB and a bandwidth of 7 MHz.
The video demodulation circuit is made from the built-in PLL
Sync Detector. The spectrum of the demodulation carrier is
unitary and it is 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. The built-in PLL
circuit of the UOCIII generates a 38.0 MHz or 38.9 MHz
demodulation reference signal for the sync detector to
demodulate the video signal; this is called “PLL sync
demodulation”.
9.2.3Sound Channel
An external ceramic filter is used to select the second SIF
signal for the sound channel of UOCIII from the signal output of
the video detector. The audio signal is obtained after limiting
amplification and demodulation by the intermediate frequency
detector for the SIF signal, and then the audio signal is fed to
the BTSC stereo/SAP decoder TDA9850. From that it is output
to the audio amplifier TFA9842, which drives the speakers to
provide the sound. The intermediate frequency detector and
volume-control attenuator that are built in the UOCIII are set
and adjusted via the CPU.
9.2.4BTSC stereo/SAP decoder
resonator. The stereo channel separation is adjusted by an
automatic procedure to be performed during set production.
The stereo identification can be read by the I
different pilot thresholds (data STS = 1; STS = 0) can be
selected via the I
SAP Demodulator
The composite signal is fed from the output of the input level
adjustment stage to the SAP demodulator circuit through a 5fH
band-pass filter. The demodulator level is automatically
controlled. The SAP demodulator includes an internal field
strength detector that mutes the SAP output in the event of
insufficient signal conditions. The SAP identification signal can
be read by the I
Noise Detector
The composite input noise increases with decreasing antenna
signal. This makes it necessary to switch stereo or SAP off at
certain thresholds. These thresholds can be set via the I
bus. With ST0 to ST3 the stereo threshold can be selected and
with SP0 to SP3 the SAP threshold. A hysteresis can be
achieved via software by making the threshold dependent of
the identification bits STP and SAPP.
Mode Selection
The stereo/SAP switch feeds either the L - R signal or the SAP
demodulator output signal via the internal dbx noise reduction
circuit to the dematrix/switching circuit. Different switch modes
provided at the output pins OUTR and OUTL are available.
dbx Decoder
The dbx circuit includes all blocks required for the noise
reduction system in accordance with the BTSC system
specification. The output signal is fed through a 73 ms fixed deemphasis circuit to the dematrix block.
SAP Output
Independent of the stereo/SAP switch, the SAP signal is also
available at pin SAP. At SAP, the SAP signal is not dbx
decoded. The capacitor at SDE provides a recommended deemphasis (150 ms) at SAP.
Integrated Filters
The filter functions necessary for stereo and SAP demodulation
and part of the dbx filter circuits are provided on-chip using
transconductor circuits. The required filter accuracy is attained
by an automatic filter alignment circuit.
9.2.5CRT Drive Circuit
In the driver circuit, both the voltage and current of the R/G/B
signal are amplified, after which the CRT drive circuit
modulates the cathode beam current of the CRT. The R/G/B
signal input into the driver circuit is of negative polarity.

Input Level Adjustment
The composite input signal is fed to the input level adjustment
stage. The control range is from -3.5 to +4.0 dB in steps of
0.5 dB. The maximum input signal voltage is 2 V (RMS).
Stereo Decoder
The output signal of the level adjustment stage is coupled to a
low-pass filter which suppresses the baseband noise above
125 kHz. The composite signal is then fed into a pilot detector/
pilot cancellation circuit and into the MPX demodulator. The
main L + R signal passes a 75 ms fixed de-emphasis filter and
is fed into the dematrix circuit. The decoded sub-signal L - R is
sent to the stereo/SAP switch. To generate the pilot signal the
stereo demodulator uses a PLL circuit including a ceramic
9.2.6Power Supply Circuit
The function of the power supply circuit is to supply various
stabilized operating voltages and to provide protections against
excessive voltages and currents.
