2. Safety Instructions, Warnings, and Notes

Index of this chapter:2.1 Safety Instructions2.2 Maintenance Instructions2.3 Warnings2.4 Notes

2.1 Safety 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.

2.2 Maintenance 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.

2.3 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).

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.

2.4 Notes

2.4.1 General

• 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.

Directions for Use EN 5SK5.0l CA 3.

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 (μ= 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.

2.4.3 Lead-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

avoid mixed regimes. If this cannot be avoided, carefully clear the solder-joint from old tin and re-solder with new tin.

2.4.4 Alternative BOM identification

In September 2003, Philips CE introduced a change in the way the serial number (or production number, see Figure 2-2) 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.

2.4.5 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.

Service Modes, Error Codes, and Fault FindingEN 8 SK5.0l CA5.

5. Service Modes, Error Codes, and Fault Finding

Index of this chapter:5.1 Test Points5.2 Service Modes5.3 Error Codes5.4 Fault Finding

5.1 Test Points

See chapter 6 "Block Diagrams, Testpoint Overviews, and Waveforms". Perform measurements under the following conditions:• Service Default Mode.• Video: colour bar signal.• Audio: 3 kHz left, 1 kHz right.

5.2 Service 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.

5.3 Error Codes

Not applicable.

5.4 Fault 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.

5.4.2 Horizontal 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.

5.4.3 Picture Interference

• Check if the signal line contact is good.• Change Tuner if is necessary.

5.4.4 Can'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.

5.4.5 No 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.

5.4.6 Picture 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.

5.4.7 Picture 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.

5.4.8 Remote 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.

5.4.9 No 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.

5.4.10 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.

8.1 General Alignment Conditions

8.1.1 Default Alignment Settings

Perform all electrical adjustments under the following conditions:• Power supply voltage: 230 VAC / 50 Hz (± 10%). • Connect the set to the mains via an isolation transformer

with low internal resistance.• Allow the set to warm up for approximately 20 to 30

minutes.• Measure voltages and waveforms in relation to chassis

ground (with the exception of the voltages on the primary side of the power supply).Caution: never use heatsinks as ground.

• Test probe: 100: 1, Ri > 10 Mohm, Ci < 3.5 pF.• Use an isolated trimmer/screwdriver to perform

alignments.

8.2 Hardware Alignments

For this TV set there are no hardware alignments.

8.3 Software Alignments

Put the set in its MENU mode (factory mode) as follows (see also figure “Factory Mode” on the next page):• Press the keys [i+], “smart sound” and “smart picture” to

enter the factory menu.• Press the keys [i+] again and “ADJUST” appear on screen.• Press the number keys to enter the adjust page, press B /

y to choose the items that to be adjusted, Press z /A to adjust its value.

• Press [i+] to quit factory mode.The different alignment parameters are described further on.

8.3.1 Rf AGC Voltage Adjust

1. Provide a 294.25 MHz, 60 dB half colour bar signal.2. Enter factory mode and press key 1. 3. Measure tuner AGC point voltage, adjust AGC item till the

voltage is 2.2 V, or till picture noise just disappears. (typical value is at 32).

8.3.2 Focus Fine Adjust

1. Provide a cross-hatch pattern signal.2. Set state to “Rich” mode. 3. Adjust flyback transformers Focus knob till picture is clear.

8.3.3 Screen Voltage Adjust

1. Set picture to “Standard” mode, without signal input.2. Press the keys [i+], “Smart sound” and “Smart picture” to

enter the factory menu. When in “B/W BALANCE” page, press “mute” on the RC. There will be a level light line displays.

3. Adjust flyback transformers Screen knob till the level bright line just can be seen.

4. When in the light-line screen, CUT R and CUT G can be adjusted if needed with the following RC key mapping:To increase /decrease CUT R (See table 8-1)To increase /decrease CUT G (See table 8-2)

5. Press “MUTE” key to return to the “B/W BALANCE” page.

Table 8-1 To increase /decrease CUT R

Table 8-2 To increase /decrease CUT G

8.3.4 Horizontal Adjustment (Key 1)

1. Provide a 50 Hz monoscope pattern.– Press the keys [i+], “Smart sound” and “Smart picture”

to enter the factory menu. – Press the keys [i+] again and “ADJUST” appear on

screen. 2. Press key “0” and adjust “HPH” to set picture horizontal

centre to CRT horizontal centre.

8.3.5 Vertical & YUV/RGB Horizontal Adjust (Key 2)

1. Provide a 50 Hz cross hatch signal, set TV to standard mode. Adjust VSL so that half picture of the pane cross appears. The picture’s vertical line is just at the bottom of the half picture. Adjust VSL to make the centre of the picture’s vertical line and the kinescope are in superposition.

2. Adjust VSI to obtain picture’s vertical re-display ratio more than 90%.

3. Provide a 60 Hz cross hatch signal, do step 1 and 2 again to adjust.

4. If necessary, fine adjust above items.

8.3.6 OSD Position (Key 4)

1. Menu OSD position adjustment: Provide a 50/60 Hz cross hatch pattern. Put the set in MENU mode. – Press the keys [i+], “Smart sound” and “Smart picture”

to enter the factory menu. – Press the keys [i+] again and “ADJUST” appears on

screen. 2. Press key 4 to enter the factory mode. Adjust VP and HP

item, to obtain menu OSD at the centre of CRT screen.3. Provide a RGB or YUV cross hatch signal, set the TV in the

standard mode, adjust “YUV OSD HS” till picture horizontal centre is at the CRT centre (optional).

9.1 Introduction

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.

9.2 The various circuits

9.2.1 Tuner

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.

9.2.2 IF 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”.

9.2.3 Sound 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.

9.2.4 BTSC stereo/SAP decoder

Input Level AdjustmentThe 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 DecoderThe 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

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 I2C-bus. Two different pilot thresholds (data STS = 1; STS = 0) can be selected via the I2C-bus.

SAP DemodulatorThe 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 I2C-bus.

Noise DetectorThe 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 I2C-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 SelectionThe 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 DecoderThe 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 de-emphasis circuit to the dematrix block.

SAP OutputIndependent 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 de-emphasis (150 ms) at SAP.

Integrated FiltersThe 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.

9.2.5 CRT 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.

9.2.6 Power 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.
