Safety instructions, maintenance instruction, warnings and Notes

2. Safety instructions, maintenance instruction, warnings and Notes

2.1 Safety instructions for repairs

1. Safety regulations require that during a repair: – The set should be connected to the mains via an

isolating transformer;

– Safety components, indicated by the symbol h,

should be replaced by components identical to the original ones;

– When replacing the CRT, safety goggles must be

worn.

2. Safety regulations require that after a repair the set must be returned in its original condition. In particular attention should be paid to the following points. – As a strict precaution, we advise you to resolder the

solder joints through which the horizontal deflection current is flowing, in particular ('general repair instruction'):

• 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 to the deflection

coil;

• Other components through which the deflection current flows.

• Note:

• This resoldering is advised to prevent bad

connections due to metal fatigue in solder joints and is therefore only necessary for television sets older than 2 years.

– The wire trees and EHT cable should be routed

correctly and fixed with the mounted cable clamps.

– The insulation of the mains lead should be checked for

external damage.

– The mains lead strain relief should be checked for its

function in order to avoid touching the CRT, hot components or heat sinks.

– The electrical DC resistance between the mains plug

and the secondary side should be checked (only for sets which have a mains isolated power supply). This check can be done as follows:

• Unplug the mains cord and connect a wire between the two pins of the mains plug;

• Set the mains switch to the "on" position (keep the mains cord unplugged!);

• Measure the resistance value between the pins of the mains plug and the metal shielding of the tuner or the aerial connection on the set. The reading should be between 4.5 MΩ and 12 M

• Switch off the TV and remove the wire between the two pins of the mains plug.

– The cabinet should be checked for defects to avoid

touching of any inner parts by the customer.

hhhh

2.2 Maintenance instruction

It is recommended to have a maintenance inspection carried out by a qualified service employee. 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 3 to 5 years.

– When the set is used in circumstances with higher dust,

grease or moisture levels, for example in a kitchen, the recommended interval is 1 year.

– The maintenance inspection contains the following actions:

• Execute the above mentioned 'general repair

instruction'.

• Clean the power supply and deflection circuitry on the chassis.

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

2.4 Notes

The direct voltages and oscillograms should be measured with regard to the tuner earth (H), or hot earth (I) as this is called. The direct voltages and oscillograms shown in the diagrams are indicative and should be measured in the Service Default

Ω

Mode (see chapter 8) with a colour bar signal and stereo sound (L:3 kHz, R:1 kHz unless stated otherwise) and picture carrier at 475.25 MHz. Where necessary, the oscillograms and direct voltages are measured with (D) and without aerial signal (E). Voltages in the power supply section are measured both for normal operation (G) and in standby (F). These values are indicated by means of the appropriate symbols. The picture tube PWB 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.

• COMPAIR mode

5.2.1 Service Default Mode (SDM)

The purpose of the SDM is:

GB 10 L9H.2E5.

Service Modes, DST, error messages, protections, fault finding and repair

• provide a situation with predefined settings to get the same measurements as in this manual

• start the blinking LED procedure

• Setting of options controls

• Inspect the error buffer

Entering the SDM:

• By transmitting the "DEFAULT" command with the RC7150 Dealer Service Tool (this works both while the set is in normal operation mode or in the SAM)

• RC sequence 062596 followed by the key “MENU” (only via set up remote, T374A)

The information displayed on the screen in the SDM mode is given in fig. 5.1 (SDM menu).

Exit the SDM:

Switch the set to Standby or press EXIT on the DST (the error buffer is also cleared). Note: When the mains power is switched off while the set is in SDM, the set will switch to SDM immediately when the mains is switched on again. ( The error buffer will not be cleared ).

5.4 Error code buffer and error codes

5.4.1 Error code buffer

The error code buffer contains all errors detected 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, the error is written at the left side and all other errors shift one position to the right

• the error code buffer will be cleared in the following cases:

1. exiting SDM or SAM with the “Standby" command on

the remote control

2. transmitting the commands “EXIT” with the DST

(RC7150)

3. transmitting the commands “DIAGNOSE-9-9-OK” with

the DST.

• The error buffer is not reset when the set is switched off by the mains switch.

Examples:

• ERROR: 0 0 0 0 0 : No errors detected

• ERROR: 6 0 0 0 0 : Error code 6 is the last and only

detected error

• ERROR: 5 6 0 0 0 : Error code 6 was first detected and error code 5 is the last detected (newest) error

The audio sub menu (for stereo sets only) contains the following items:

• ST-NT : Stereo noise treshold (only if option SB=50)

• SAP-NT : SAP noise treshold (only if option SB=50)

• LA : Input level adjust (only if option SB=50/52/55)

• WIDEB : Stereo adjust for wide band expander (only if option SB=50/52/55)

• SPECT : Stereo adjust for special expander (only if option SB=50/52/55)

• AT : Attack time at AVL (only if option SB=52/55)

• STEREO : Stereo adjust MSP34xx (only if option SB=IT/NB/NDIT)

The sound adjustments sub menu is not available in Mono sets. The presence of an item in the menu strongly depends on the selected sound board (option SB).

5.4.2 Error codes

In case of non-intermittent faults, clear the error buffer before starting the repair to prevent that “old” error codes are present. If possible check the entire content of the error buffers. In some situations an error code is only the RESULT of another error code (and not the actual cause). Note: a fault in the protection detection circuitry can also lead to a protection. a. Error 0 = No error b. Error 1 = X-ray ( Only for USA sets ) c. Error 2 = High beam current protection

– High beam protection active; set is switched to

protection; error code 2 is placed in the error buffer; the LED will blink 2 times ( repeatedly ).

– As the name implies, the cause of this protection is a

too high beam current (bright screen with flyback lines). Check whether the +160V supply to the CRT panel is present. If the voltage is present, the most likely cause is the CRT panel or the picture tube. Disconnect the CRT panel to determine the cause. If

• flyback capacitor 2434

• line output stage

• short circuit of flyback diode 6434

This error is usually detected during start-up and hence will

prevent the set from starting up. c. Error 6 = Bimos (TDA884x ) IIC error Note that this error may also be reported as a result of error codes 4 (in that case the Bimos might not be the actual problem) a. Error 7 = General IIC error. This will occur in the following

cases:

• SCL or SDA is shorted to ground

• SCL is shorted to SDA

• SDA or SCL connection at the micro controller is open

circuit.

b. Error 8 = Microprocessor ( IC7600 ) internal RAM error ( A7

) The micro controller internal RAM test indicated an error of the micro controller internal memory (tested during start-up); a. Error 9 = EEPROM Configuration error ( Checksum error );

EEPROM is corrupted. b. Error 10 = IIC error EEPROM . NV memory (EEPROM)

does not respond to the micro controller c. Error 11 = IIC error PLL tuner. Tuner is corrupted or the IIC

line to the Tuner is low or no supply voltage present at pin

9, pin 6 or pin 7 of the tuner.

5.6 Customer Service Mode (CSM)

The set is equipped with the “Customer Service Mode” (CSM). CSM is a special service mode to identify the status of the set. It can be activated and deactivated with the set-up remote transmitter (RG4172BK). The CSM is a 'read only' mode, therefore modifications in this mode are not possible.

5.6.1 Entering the Customer Service Mode (in “Commercial mode)

The Customer Service Mode can be switched on by pressing RECALL on the set-up remote control RG4172BK. When the CSM is activated:

• picture and sound settings are set to nominal levels

•“Service unfriendly modes” are ignored

• In “Consumer mode”: RC “Mute” = local keyboard buton >4

seconds simultaneously

5.6.2 Exit the Customer Service Mode

The Customer Service Mode will switch off after:

• pressing one of the keys RECALL or MENU on the set-up

remote control RG4172BK

• switching off the TV set with the mains switch. All settings that were changed at activation of CSM are set back to the initial values

5.6.3 The Customer Service Mode information screen

The following information is displayed on screen:

5.5 The “blinking LED” procedure

The contents of the error buffer can also be made visible through the “blinking LED” procedure. This is especially useful when there is no picture. There are two methods:

• When the SDM is entered, the LED will blink the number of times, equal to the value of the last (newest) error code (repeatedly).

• With the DST all error codes in the error buffer can be made visible. Transmit the command: “DIAGNOSE x OK” where x is the position in the error buffer to be made visible x ranges from 1, (the last (actual) error) to 5 (the first error). The LED will operate in the same way as in point 1, but now for the error code on position x.

Example: Error code position1 2 3 4 5 Error buffer:8 9 5 0 0

• after entering SDM: blink (8x) - pause - blink (8x) - etc.

• after transmitting “DIAGNOSE- 2- OK” with the DST blink

(9x) - pause - blink (9x) - etc.

• after transmitting “DIAGNOSE- 3- OK” with the DST blink(5x) - pause - blink(5x) - etc.

• after transmitting “DIAGNOSE- 4- OK” with the DST nothing happens

5.7 ComPair

5.7.1 Introduction

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

• ComPair helps you to quickly get an understanding how to repair the sets in short time by guiding you step by step through the repair procedures.

• ComPair allows very detailed diagnostics (on I is therefore capable of accurately indicating problem areas. You do not have to know anything about I yourself; ComPair takes care of this.

• ComPair speeds up the repair time since it can automatically communicate with the sets (when the micro processor is working) and all repair information is directly available. When ComPair is installed together with the SearchMan electronic manual, schematics and PCBs are only a mouse-click away.

ComPair consists of a Windows based fault finding 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 L9H chassis, the ComPair interface box and the L9H communicate via an IIC cable (bidirectional) and via infra red communication (uni-directional; from ComPair interface box to L9H. The ComPair fault finding program is able to determine the problem of the defective television. ComPair can gather diagnostic information in 2 ways:

1. Communication to the television (automatic)

2. Asking questions to you (manually)

ComPair combines this information with the repair information in its database to find out how to repair the set.

Automatic information gathering

Reading out the error buffer, ComPair can automatically read out the contents of the entire error buffer. Diagnosis on I television. ComPair can send and receive I micro controller of the television. In this way it is possible for ComPair to communicate (read and write) to devices on the I busses of the

2

C level. ComPair can access the I2C bus of the

2

C commands to the

2

C level) and

2

C commands

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.

Additional features

Beside fault finding, ComPair provides some additional features like:

• Uploading/downloading of presets

• Managing of preset lists

• Emulation of the Dealer Service Tool

Connecting the ComPair interface

The ComPair Browser software should be installed and set-up before connecting ComPair to the set. (See the ComPair Browser Quick Reference Card for installation instructions.)

Connect the RS232 interface cable to a free serial

Manual information gathering

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 fault finding tree by asking you questions and showing you examples. You can answer by clicking on a link (e.g. text or an waveform pictures) that will bring you to the next step in the faultfinding process. A question could be: Do you see snow? (Click on the correct answer) YES / NO An example can be: Measure test point I7 and click on the correct oscillogram you see on the oscilloscope

5.9.1 THE DEFLECTION CIRCUIT:

1. Measure the +VBATT ( 95V) is present across 2551 ( A2 Line deflection ). If the voltage is not present, disconnect coil 5551. (Horizontal deflection stage is disconnected). If the voltage is present then the problem might be caused by the deflection circuit. Possibilities:

• Transistor 7402 is faulty

• The driver circuit around transistor 7400 is faulty

• No horizontal drive signal coming from the BIMOS

7250-D pin 40 ( A4 - Synchronisation )

• Timer-IC 7607 or transistor 7608 is defect ( A7 -

Control )

2. Note: If the Collector of 7402 is shorted to the Emitter, hickup noise can be heard from the power supply. In this case the E/W protection is disabled. is correctly working ( a parabolic picture )

3. Also take note of protection circuits in the line output stage. If any of these circuits are activated, the set will shut down. Depending on the protection, the led will blink according to the fault defined. In order to determine which protection circuit is active, isolation of each separate circuit is necessary. These protection circuits are:

• High beam current protection ( LED blinks repetitively

2 times ) - CRT panel ( B )

• Vertical protection ( LED blinks repetitively 3 times ) -

Vertical deflection ( A3 )

5.9.2 THE POWER SUPPLY

To trouble shoot the L9 SMPS, first check the Vaux voltage on C2561. If this voltage is not present, check fuse F1572 and D6560. If F1572 or D6560 is not open circuit, the problem might be caused on the primary side of the switching supply. Check the output of the bridge rectifier on C2508 for approximately 300V DC at an input voltage of 230Vac. If this voltage is missing, check the bridge diodes 6502 .. 6505 and the fuse

1500. If fuse F1500 is found open, check MOSFET 7518 to

make sure that there is no short circuit present and check R3518. If the 300V DC is present on C2508, check for a startup voltage of approx. 13V on pin 1 of IC7520. If no start-up voltage is present, check if R3510 is open or diode 6510 is a short-circuit. It is necessary to have a feedback signal from the hot primary side of switch mode transformer T5545 at pin 1 and pin 2 for the power supply to oscillate. If the start-up voltage of 13V is present on pin 1 of IC7520 and the supply is not oscillating, check R3529 and D6540. Check for a drive signal at the gate of MOSFET 7518, square wave signal - P1. Check pin 3 of IC7520 and R3525. To determined whether OVP is active, check the presence of Vaux at C2561.

Circuit description new circuits

9. Circuit description new circuits

9.1 Introduction

9.1.1 General

The switch mode power supply (Fixed Frequency ) is mains isolated. The control IC7520 (MC44603A) produces pulses for driving FET 7518. Power supply regulation is achieved by using duty cycle control at a fixed frequency of nominal 70 kHz in normal operation. In stand-by, slow-start and overload situations the SMPS runs at frequencies other than 70 kHz. Basic characteristics of this SMPS :

• Mains Isolated flyback Converter type

• Input range : 150 - 276 Volts AC

• Secundaire voltage adjustment via potentiometer R3540 at the primary side

• IC7520 is featured with Slow-Start circuitry

• Protection Circuits

• Degaussing circuit

9.1.2 Output voltages

• AudioSupply 10V/14V ( +18V ) for the Sound amplifier ( D2 )

• Vbatt/MainSupply ( +95V ) for the Line deflection stage (A2), Tuner video IF ( A5 )

• Vaux / MainAux ( +9.5V ) for the Line Deflection ( A2 ) and the Control (A7)

9.1.3 The switching periods of TS7518

becomes high-ohmic which reduces the degaussingcurrent. During normal operation, the degaussing current is signal.very small, because of the high impedance of PTC R3504.

9.2.2 Start up and take over

• Start-up : The start-up circuitry consisting of 3510, 3530 and 3529 use the voltage coming from the 230V AC mains to start-up IC7520 via the supply pin 1. The output drive waveform (pin 3) is blocked by using the ICs internal logic until the voltage on pin 1 reaches 14.5 Volts however with less than 14.5 volts on Pin 1 the IC only consumes 0.3mA. Once pin 1 reaches the 14.5 Volts threshold, IC7520 will start up (FET 7518 will conduct) and pin 1 sinks a typical supply current of about 17 mA. This supply current cannot be delivered by the start-up circuitry, so a take-over circuit must be present. If take-over does not occur then the voltage on pin 1 will decrease below 9V and IC7520 will switch off. The supply begins a new Start-up cycle, see top of this paragraph. This cycle will repeat itself and can be noticed by an audible hick-up sounding noise.

• Take over : During start-up a voltage across winding 1-2 is gradually built up. At the moment the voltage across winding 1-2 reaches approx. (14.5 Volts, D6540 start conducting and takes over the supply voltage Vpin 1 of IC7520 (take over current is approx. 17mA).

Note: This power supply is a FFS (= Fixed Frequency Supply) and not a SOPS (= Self Oscillating Power Supply).

The power supply duty cycle is dependent on the T-on of FET

7518. The FET is driven by pin 3 of IC7520. This IC controls the secondary voltage (VBATT via potentiometer 3540. The primary voltage at pin1-2 of transformer 5545 is rectified by D6537 and smoothed by C2537. The switching period of TS7518 can be divided into three main phases: Duty cycle Ton, T-off and T-dead.

• During T-on, FET 7518 conducts.

• Energy is stored in the primary winding (4-7) of transformer T5545 by using a linear increasing primary current. The slope depends on the rectified mains-voltage present across C2508. The T-on period is varied to provide regulation of the drive waveform at pin 3 of IC7520. By controlling the duty cycle of the SMPS in this way the (VBATT is controlled.

• During T-off, FET 7518 is switched off and therefore does not conduct. The energy is now transferred to the secondary side of the transformer and then supplied to the load via the secondary diodes (D6550, D6560 and D6570). The current through the secondary side of the transformer decreases until it reaches zero.

• During T-dead FET 7518 does not conduct .The voltage at the drain of the FET decays and eventually reaches the input voltage of approximately 300V.

9.2 Primary side

9.2.1 Mains input and degaussing

• Mains voltage: this voltage is filtered by L5500 and L5501, rectified by the bridge diode 6502 .. 6505 and then smoothed by C2508 which provides a DC input voltage of 300V DC for an ac input voltage of 230V.

• Degaussing : R3504 is a PTC. When switching "on" the set, the PTC is cold and has a low-ohmic value. This allows a very high degaussing current at initial power on. The PTC will then heat up due to the high current involved and

9.3 Control circuitry

9.3.1 IC7520 control mechanisms

IC7520 controls the T-on time of FET 7518 in three different ways:

• "Primary-voltage-sensing" controls the secondary output voltages via the feedback voltage pin 14

• "Primary current sensing" controls the maximum primary current via the current sense voltage pin 7

• "Demagnetization control" prevents the transformer T5545 from going into saturation via the so-called "DEMAG" function at pin 8

9.3.2 Secondary voltage sensing (pin 14 of IC7520)

When the output voltage +VBATT increases (due to a reduction in the load ) the primary voltage at winding 1-2 will increase, therefore the voltage across capacitor 2537 increases. This will reduce the on-time of FET 7518 due to an increase of the voltage present on pin 14. In the event of an increase of the load (decrease of output voltage +VBATT ), the control circuit will work in the opposite way to the explanation above.

9.3.3 Primary sensing (pin 7 of IC7520)

The current sense voltage at pin 7 is used to measure the primary current through FET7518. The primary current is converted into a voltage by R3518.

9.3.4 Demagnetization control (pin 8 of IC7520)

Winding 1-2 has the same polarity as the secondary winding that supplies the load. When FET 7518 is turned off the voltage at winding 1 becomes positive. The power supply transfers the

Circuit description new circuits

GB 53L9H.2E 9.

stored energy at the secondary side. Until the transformer is demagnetized the voltage on the winding remains positive. At the moment that the energy is fully transferred to the load, the voltage at pin 9 of the transformer becomes negative. Additionally with a certain dead time the voltage at control pin 8 of IC 7520 also drops below zero which releases the output buffer (pin 3) and a new cycle starts.

9.3.5 Peak current limiting

An internal clamp at pin 7 allows peak current limiting to be achieved . This pin can never exceed 1V DC and so the maximum primary current through FET 7518, and also the maximum output power is determined. In case of an output being short-circuited or loaded excessively, the I-prim becomes too high which is detected by pin 7. As a result the primary current is limited to its maximum value and the secondary voltages will drop. The voltage at pin 1, which is coupled with the output voltage, will also drop. When the voltage at pin 1 drops below the 9V, IC7520 will stop functioning and the output voltage will rapidly drop to zero. Via start-up circuitry 3510, 3530 and 3529 the voltage originating from the 230V AC mains is used to start-up IC7520 via the supply pin 1. As soon as this voltage reaches the 14.5V, IC7520 starts functioning. If the load is still too much or the output is short-circuited the same cycle will happen again. This fault condition can be clearly identified as the power supply will be loudly tripping.

9.3.6 Slow-start

As soon as Vpin 1 > 14.5V the SMPS will start-up. During the slow-start procedure both the frequency and the duty cycle will be built up slowly. The duty cycle will initially slowly increase commencing with the absolute lowest possible duty cycle. The maximum duty cycle is determined by C2530 at pin 11 of IC7520, as C2530 is uncharged at start-up.

9.3.7 Standby mode

In standby mode the SMPS switches to the so-called "reduced frequency mode" and runs at about 20 kHz. During standby the SMPS only has to deliver a minimal level of output power. The minimal load threshold level is determined by R3532 at pin 12. In the L9 chassis the SMPS does not have a burst mode in standby but only a reduced frequency mode of about 20 kHz as stated above. In normal operation mode the internal oscillator is around 70 kHz. This frequency is controlled by C2531 at pin 10 of IC7520 and by R3537 at pin 16 of IC7520. In standby mode the frequency of operation is determined by R3536 at pin 15 of IC7520.

9.3.8 Protections

Over voltage protection of the secondary voltages.

After start-up the supply voltage pin 1 will be "taken over" by winding 1-2. Pin 1 of IC 7520 is used to detect an over voltage situation on the secondary side of the transformer. If this voltage exceeds 17V (typical ), the output buffer is disabled, and IC 7520 goes into over voltage protection and a complete restart sequence is required. Check in this case IC7520, D6537 and the secondary voltage +VBATT ( +95V ). REMARK: In the event of the over voltage situation remaining present, the SMPS will go in protection, start up cycle, protection, etc. The standby led on the front of the set starts flashing.

Under voltage protection of the secondary voltages

If the supply voltage at pin 1 of IC 7520 drops below 9V because of a short-circuit or excessive load, the drive pulse present at pin 3 will be disabled and IC7520 will switch off the

complete SMPS. Capacitor C2540 is charged up via start-up resistors if3529,3510 and 3530, however once the voltage exceeds 14.5V start up threshold, the SMPS will once again commence a re start cycle. In the event of the under voltage situation remaining, the SMPS will again go in protection mode, start up cycle, protection, etc. and so the cycle repeats. This effect is highly audible.

9.5 Tuner and Video IF (see circuit diagram A5)

9.5.1 Introduction:

In Figure 9-4 a simplified block diagram of the video path is shown. The main item in the block diagram shown in Fig.9.14 is the video processor item 7250. The IC performs the following functions, video IF demodulation, chroma processing and RGB processing. Additionally synchronisation processing, mono IF audio demodulation and audio selection takes place. The used video processor:

• TDA8842 N2 for SW CENELEC BG/DK, CENELEC I

For a detailed block diagram of the TDA8844/8845 see Figure 9-3.

9.5.2 Tuner

2

The PLL tuner (item 1000) is digitally controlled via the I The tuner is suitable to receive off-air, S-(cable) and hyper band channels. Tuner pin description:

• Pin 1: AGC, Automatic gain control voltage input (0.3 -

4.0V)

• Pin 2: VT, tuning voltage input (not connected)

• Pin 3: AS, address select (not connected)

• Pin 4: SCL, IIC-bus serial clock

• Pin 5: SDA, IIC-bus serial data

• Pin 6: not connected

• Pin 7: Vs, PLL supply voltage +5V

• Pin 8: not connected

• Pin 9: Vst, tuning voltage +33V

• Pin 10: ground

• Pin 11: IF, asymmetrical IF output Note: The +5V supply voltage and the +33V tuning voltage is derived from the line output stage, see diagram A2).

9.5.3 IF band pass filter (SAW FILTER)

C-bus.

The main functions of the video IF part are (see also figure 9-3):

• IF- amplifier

• PLL-demodulator

• Video buffer

• AFC

• IF-AGC

• Tuner AGC

9.5.5 IF- amplifier

The IF-amplifier incorporates symmetrical inputs (pins 48 and

49). By using IIC bus control (IFS) the AGC attenuation can be adjusted by up to -20dB. Remark: If the BIMOS is replaced the AGC value should be adjusted as part of the repair process. ( see Ch 8 - Alignments ).

9.5.6 PLL-demodulator

The IF-signal is demodulated with the assistance of the PLL detector. The video IF-demodulator can handle both negative and positively modulated IF signals; selection is achieved via the IIC bus (bit MOD).

9.5.7 Video buffer

The video buffer is present to provide a low ohmic video output with the required signal amplitude. Additionally, it provides protection against (pin 6) the occurrence of noise peaks. The video buffer stage also contains a level shifter and a gain stage for both the positive and negative video modulation formats, so that the correct video amplitude and DC level are always present at pin 6 regardless of the input signal.

9.5.8 Video-IF AGC

An AGC system controls the gain of the IF amplifier such that the video output amplitude is constant. The demodulated video signal is supplied, via a low pass filter inside the IC to an AGC detector. External AGC de coupling is provided by capacitor 2201 at pin 53. The AGC detector voltage directly controls the IF amplification stages.

9.5.9 The tuner AGC

Tuner AGC is provided to reduce the tuner gain and thus the tuner output voltage when receiving to strong RF signal. The tuner AGC starts working when the video-IF input reaches a certain input level. This level can be adjusted via the IIC bus. The tuner AGC signal is applied to the tuner via the open collector output pin 54 of the BIMOS.

Between the tuner output and the video IF input of the video processor the IF band pass filtering take place. For the IF band pass filtering SAW filters are used (item 1003 or 1005). 5 Types of SAW filters are used depending on the version of the set.

9.5.4 Video IF

General: Video IF-demodulation is achieved in combination with reference circuit L5006 connected at pin 3 and 4 of IC7250-A. The AGC control for the tuner is applied via pin 54 of IC7250-A. Internally the IC uses the top sync level as a reference for AGC control. The AGC adjustment can be readjusted via the SAM (service alignment menu). C2201 connected to pin 53 determines the time constant of the AGC. The Base band CVBS signal is present at pin 6 of IC7250-A (normal amplitude 3.2Vpp). From here the signal is fed via transistor 7266 to the sound trap filters and then on to the video source selection circuit.

9.5.10 AFC

The AFC output information is available for search tuning. The AFC output is available via the I For alignment purposes it is displayed in the TUNER submenu of the SAM (See chapter 8).

9.6.4 PAL and SECAM demodulation via the Auto system manager

The colour decoder circuit detects whether the signal is a PAL signal. The result is made known to the auto system manager. The base-band delay line is activated when a PAL or SECAM signal is detected. For the SECAM colour standard a reference voltage is generated at pin16 of the TV-processor. Connected at Pin 9 of the TV-processor, is the band-gap decoupling circuit, which consists of (2214,2215). The band-gap circuit provides a very stable and temperature independent reference voltage. It ensures optimal performance of the TVprocessor and is used by almost all functional blocks inside the processor. The Y signal and the demodulator outputs R-Y and B-Y are present at pin 28, 29, 30 of the TV-processor. The auto system manager identifies PAL and SECAM colour standards and is controllable via the IIC bus. Connected on pin 36 of the TV-processor is the Loop Filter for the phase detector The filter chosen provides an optimal transient response, which ensures both an optimum for noise bandwidth and colour acquisition time.

9.6.5 YUV / RGB processing/ black stretching

The signal Y, R-Y and B-Y present on pins 27, 31, 32 of the TVprocessor are used as the input signals for the colour decoding section of the BiMOS (IC7520-C). The YUV processor enables the colour saturation control and also converts the Y, B-Y and B-Y signals to the R, G, B signal format via the colour matrix circuit. The black stretcher circuit , initial stage of the matrix circuit, extends the Grey signal level towards the actual black level. The amount of extension depends upon the difference between actual black level and the darkest part of the incoming video signal level. This feature is fully integrated. The user can switch this circuit on or off by using the Contrast Plus option in the user menu.

9.6.6 Second RGB insertion

Pins 23, 24, 25 are used as the inputs for the second R, G, B signals insertion. Pin 26 of the TV-processor is the input for the insertion control signal which is called "FBL". When the FBL signal level becomes higher than 0.9V (but less than 3V) the R, G, B signals at pins 23,24,25 are inserted into the picture by using the internal switches incorporated in the TV-processor. This second insertion possibility is used for insertion of the on screen display signals , TXT or R. G. B signals from the SCART socket.

9.6.7 RGB processing

9.6.3 Luminance / Chroma signal processing

Once the signal source has been selected, CHROMA filter calibration is performed. The received colour burst-sub-carrier frequency is used for the calibration. Correspondingly, the CHROMA band-pass filter for PAL processing or the cloche filter for SECAM processing is switched on. Pins 34, 35 have the crystals connected to them. These crystals are used for multi-purpose calibration of the burst sub-carrier. The selected luminance signal is then supplied to the Horizontal and Vertical synchronisation processing circuits and to the luminance processing circuits. In the Luminance processing block, the luminance signal is applied to the CHROMA trap. This trap is switched on or off depending upon on the colour burst detection of the CHROMA calibration circuit. Before the luminance signal is applied to pin 28 of the TV-processor the signal is applied to a "peaking" and "coring" circuit. In these circuits the sharpness and noise level of the signal can be influenced via the remote control (control menu in the user menu ).

The RGB processing circuit enables the picture parameters to be adjusted by using a combination of the user menus and the remote control. Additionally automatic gain control for the RGB signals via cut-off stabilisation is achieved in this functional block.. The block also inserts the cut off point "measuring pulses" into the RGB signals during vertical retrace period.. From outputs 19,20 and 21 the RGB signals are then applied to the output amplifiers on the CRT panel.

9.6.8 Black current calibration loop

The black current calibration loop ensures that the white balance at low signal levels and low light white balance is skipped. By means of the inserted measuring pulses, the black current calibration loop, tracks the beam current feed back of the RGB signals at the cathodes of the picture tube. As a result of this calibration, the individual black level of the RGB output signals is shifted to a level which allocates around 10uAof beam current to each of the RGB signals. Pin 18 (BC_info) of

Circuit description new circuits

GB 57L9H.2E 9.

the BIMOS is used as the feed back input from the CRT base panel.

9.6.9 Beam current limiting

A beam current limiting circuit inside the BiMOS handles the contrast and brightness control for the RGB signals. This prevents the CRT tube being over driven, which may cause serious damage in the line output stage. The reference used for this purpose is the DC voltage on Pin 22 (BLCIN) of the TVprocessor. Contrast and brightness reduction of the RGB output signals is therefore proportional to the voltage present on this pin. Contrast reduction starts when the voltage on pin 22 is lower than 3.0 V. Brightness reduction starts when the voltage on pin 22 is less than 2.0 V. The voltage on pin 22 is normally 3.3V (limitor not active). To enable correct operation however, an external adaptation to the circuit is required for the correct functioning of the limiting function. This is connected to Pin 22, the circuit therefore ensures that correct peak white limiting and the average beam current limiting takes place. Components 6212, 3246 are for the average beam current limiting. As a reference for the average beam current control the signal ABL_info is used. This signal is a measurement of the picture contents. As the time constant of the filter is much bigger than the frame period time, the DC at the anode of 6212 represents the average value of the picture content. Via 6212 and 2226 the DC voltage at pin 22 is slowly. The RGB output signals are applied to the CRT panel via connector 0243. Via diodes 6213, 6214 and 6215 and series resistor 3214, the RGB signals are also connected to the CRT_discharge signal. The level of this signal is only high during the time the set is switched off. And id due to the cathodes of the CRT are driven fully negative. That means that the beam current is increased. and consequently the CRT quickly discharged.

9.8 SP/LS (Smart-plug) Diagram I

9.8.1 SP (Smart Plug)

The smart plug is a modular jack connector used for communication with external set-top boxes for interactive TV. Beside this, the smart plug can be used with a “smart-loader” for copying TV settings from one TV to another. The “smart-loader” contains a 16K NVM. When the power is switched on the micro-computer is checking the smart plug if there is any smart-loader connected. If this is the case then the user is prompted via OSD to upload or download the VNM. Via connector 0238 the data on the smart-plug is applied to the micro-computer. The pin-configuration is:

• Pin 1 Clock signal

• Pin 2 Data in (signal is inverted by 7940)

• Pin 3 + 5V

• Pin 4 Data out

• Pin 5 Ground

• Pin 6 IR Data

9.8.2 LS(Loudspeaker socket for external bathroom speaker).

The socket for the external bathroom speaker is a 3.5mm headphone socket with switch. The bathroom speaker will be connected in series with the internal mono/right speaker. The switch takes care that when the jack is unplugged the TV speaker is muted.

9.9 Smart Card Interface panel (Diagram J)

On the Smart Card Interface the 32 pin connector is mounted for plug in the Smart Card. Moreover all interface circuits (buffers) are mounted on this panel needed for interfacing between Smart Card and TV chassis.

On the CRT panel the analog output amplifiers for the RGB signals are located. The B-signal is amplified by the analog amplifier formed by a circuit build around the transitors 7331, 7332 and 7333. The G- signal is amplified by the analog amplifier formed by a circuit build around the transitors 7321, 7322 and 7323. The R- signal is amplified by the analog amplifier formed by a circuit build around the transitors 7311, 7312 and 7313. The supply voltage for the transistors is +160VA and is derived from the line output stage.

9.7 EPS (External power supply, Diagram F)

For system executions the connected Smart Card needs to be powered at all times. There for an external power supply (EPS) is needed. The EPS panel is located inside the TV set at the right side of the main chassis. The external supply is connected in parallel to the TV mains supply, bypassing the TV mains switch. The EPS is a switched mode power supply with secondary voltage sensing via an opto coupler IC2. IC1 contains the control and FET- switching function. At the secondary side 2 DC voltages +12V and +5V are available. This 2 voltages are applied to the Smart Card Interface panel. For more details see the description of the interface panel.

9.9.1 Supply

At the interface panel .via connector 0228 the +5V and +12V delivered by the EPS panel are applied. The +12V(+12Veps) is used for supplying the Interface panel and the Smart Card. Also via the diodes 7611 and 6712 this voltage is applied to pin 1 of connector 0241. This voltages is used as supply voltage for the audio part in stand by position (needed for buzzer function). The +5V(+5Veps and +5Vchas) are used for supplying the interface panel and the Smart Card . Also the +5Vchas voltage is applied to pin 5 of connector 0241.This voltage is used for supplying:

• Micro-computer item 7600 (Diagram A7)

• EEPROM (NVM) item 7601 (Diagram A7)

• IR receiver item 7680 (Diagram A8)

• LED item 6680 (Diagram A8) This is necessary because above mentioned parts need always be powered. For a quick overview of the voltage connections see supply voltage diagram in this manual.

9.9.2 Additional reset circuit item 7710, 7702, 7703

In system executions the TV microprocessor is continuously powered by the EPS panel, therefore an adapted reset circuit is needed. In system sets the original reset circuit formed by TS7605 (diagram A7) is deleted and is replaced by the reset circuit on Diagram I formed by TS7702, TS7703 and reset pulse former IC 7710. Each time the Vaux is switched on 7702 is conducting for a short time and so pin 1 of IC 7710 is short circuit to mass. If 7702 is cut off again IC 7710 starts generating a reset pulse. This reset pulse is applied to the Smart Card

9.11.1 FM-Radio item 1901

The FM radio panel is only available in non system executions. The FM tuner item 1901 is tuned by the micro-computer via the IIC bus and output expander 7904. The 12V (for internal varicap) tuning voltage on pin 8 of the FM tuner is derived from the Vbatt voltage via pin 2-0255. To give the Vbatt enough load to work properly also in stand-by position the Vbatt is in stand-by additional loaded via 3928 (3K3 5W) and 7925. In position ON this additional load is switched off via 7930. The outputs 9, 11 (L and R) of the tuner are applied to amplifier

7903. Via electronic switch IC7901 a selection can be made between TV and FM tuner sound. Only one audio channel (mono) is used (plug 0256 is not connected).

9.11.2 Smart-plug item 1950

The smart plug is a modular jack connector used for communication with external set-top boxes for interactive TV. Beside this, the smart plug can be used with a “smart-loader” for copying TV settings from one TV to another. The “smart-loader” contains a 16K NVM. On power up the micro-computer is checking the smart plug if there is any smartloader connected. If this is the case then the user is prompted via OSD to upload or download the VNM. Via connector 0238 the data on the smart-plug is applied to the micro-computer. The pin-configuration is:

On pin 3-0255 the 9V MainAux supply voltage enters the panel and is stabilized to 5V (+5E) by 7920. The +5E is used for supplying the circuits on the panel itself but is also applied via fuse 1920 to pin 5 of connector 0255. This voltage is used for a stable supply voltage for the micro-computer and NVM on Diagram A7. Loudspeaker socket for external bathroom speaker. The socket for the external bathroom speaker is a 3.5mm headphone socket with switch. The bathroom speaker will be connected in series with the internal mono/right speaker. The switch takes care that when the jack is unplugged the TV speaker is muted
