1-3 A TSS sorting method

The TV set sweeps all the TV bands from be ginning of VHF to end of UHF. The TV controlling softw are for each program checks if a VPS CNI code is transmitted. If no VPS CNI code is found, the system check if a CNI code is transmitted in the teletext lines ( Packet 8/30 f ormat 1 ). If such a code ( VPS or teletext ) is found and if this code is in the ATSS list, the program is automatically named. The programs found are then sorted in 4 groups :

Group I : It contains all the programs from the selected country and named by the TV controlling software. Within this group the sorting order is fix ed by the A TSS list.

Group II : It contains all the programs with a strong signal strength which are not listed in group I. Group III : It contains all the programs with a weak signal strength which are not listed in group I. Group IV : If two or more programs with the same code are found, only the strongest ( or if the y ha v e the

same level the one with the lo west frequenc y) is listed in group I, II or III. The others are listed in group IV.

Note : If two programs with the same name but a dif ferent code are found these two programs are listed in group I, II or III ( e.g. Regional program SW3 in Germany ).

The sorting order within group II, III, and IV is based on the channel frequency. The program with the lowest frequency is allocated the f irst rank in its group, and so f orth until the last program of the group which has the highest frequency.

Special case : France If France is selected the TV controlling software sweeps the whole TV bands f irstly with France system selected ( positive video modulation) and secondly with Europe system selected ( ne gativ e video modulation).

Special case : Switzerland If Switzerland is selected the TV controlling software sweeps the whole TV bands f irstly with Eur ope system selected (negati ve video modulation) and secondly with France system selected ( positi ve video modulation).

Special case : GB Note for satellite receiver user s : Before starting A TSS turn On your satellite recei v er and tune “ SKY NEWS “. If GB is selected the TV controlling software seeks for programs only in UHF ( C21 to C70 ). The sorting order is : 1 - BBC1 2 - BBC2 3 - ITV 4 - CH4 5 - CH5 6 - NEWS

If two or more “ identical “programs ( same name but dif ferent code e.g. BBC1 and BBC1 Scotland ) are found the following programs in the list will be shifted up. (1 - BBC1, 2 - BBC1, 3 - BBC2, 4 - ITV, 5 CH4, 6 - CH5, 7 - NEWS, ..)

If one of the program above is not found, the associated program number remains empty ( freq.=467.25 Mhz - Skip selected - no name - system=GB). example A : 1 - BBC1, 2 - BBC2, 3 - ITV, 4 - ——, 5 - CH5, 6 - NEWS, ... example B ( if 2 BBC1 found ) : 1 - BBC1, 2 - BBC1, 3 - BBC2, 4 - ITV, 5 - ——, 6 - CH5, 7 - NEWS, ...

2 - Safety instruction

WARNING: Only competent service personnel may carry out work in v olving the testing or repair of this

equipment.

X-RAY RADIATION PRECAUTION

1. Excessiv e high voltage can produce potentially hazardous X-RAY RADIATION. T o a void such hazards, the high voltage must not exceed the specif ied limit. T he nominal v alue of the high voltage of this receiver is 28 KV at max beam current. The high v oltage must not, under an y circumstances, exceed 30KV. Each time a receiver requires servicing, the high voltage should be checked. It is important to use an accurate and reliable high voltage meter.

2. The only source of X-RAY Radiation in this TV receiver is the picture tube. For continued X-RAY RADIATION protection, the replacement tube must be exactly the same type tube as specified in the parts list.

SAFETY PRECAUTION

1. Potentials of high voltage are present when this recei ver is operating. Operation of the receiv er outside the cabinet or with the back board removed in v olv es a shock hazard from the receiv er.

1) Servicing should not be attempted by anyone who is not thoroughly familiar with the

precautions necessary when working on high voltage equipment.

2) Discharge the high potential of the picture tube before handling the tube. The picture tube is

highly evacua ted and if broken, glass fragments will be violently expelled.

2. If any Fuse in this TV recei v er is blo wn, replace it with the FUSE specified in the Replacement P arts List.

3. When replacing a high wattage resistor (oxide metal film resistor) in circuit board, keep the resistor 10 mm away from circuit board.

4. Keep wires away from high v oltage or high temperature components.

5. This receiver must operate under AC 230 volts, 5O Hz. NEVER connect to DC supply or any other power or frequency.

PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in this equipment have special safety-related c haracteristics. These characteristics are often passed unnoticed by a visual inspection and the X-RAY RADIA TION protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which hav e these special safety characteristics are identified in this manual and its supplements, electrical components having such features are identif ied by designated symbol on the parts list. Before replacing any of these components, read the parts list in this manual carefully . The use of substitutes replacement parts which do not hav e the same safety characteristics as specified in the parts list may create X-RAY Radiation.

Data Capture

The Data Capture section takes in the analogue Composite Vidéo and Blanking Signal (CVBS), and from this extracts the required data, which is then decoded and stored in memory.

The extraction of the data is performed in the digital domain. The first stage is to convert the analogue CVBS signal into a digital form. This is done using an ADC sampling at 12MHz. The data and clock recovery is then performed by a Multi-Rate Video Input Processor (MuIVIP). From the recovered data and clock the following data types are extracted WST Teletext (625/525), Closed Caption, VPS, WSS. The extracted data is stored in either memory (DRAM) via the Memory Interface or in SFR locations.

- one pair of four-fold oversampled D/A converters supplying a pair of SCART-outputs. output level per channel: max. 2 V RMS, output resistance: max. 0.5 kΩ, S/N-Ratio: >85 dB (20 Hz... 16 kHz)

Application Fields of the MSP 3415D

In the following sections, a brief overview about the two main TV sound standards, NICAM 728 and German FM Stereo, demonstrates the complex requirements of a multistandard audio IC.

NICAM plus FM/AM-Mono

According to the British, Scandinavian, Spanish, and French TV-standards, high-quality stereo sound is transmitted digitally. The systems allow two high-quality digital sound channels to be added to the already existing FM/AM-channel. The sound coding follows the format of the so-called Near Instantaneous Companding System (NICAM 728). Transmission is performed using Differential Quadrature Phase Shift Keying (DQPSK. Table below offers an overview of the modulation parameters. In the case of NICAM/FM (AM) mode, there are three different audio channels available: NICAM A, NICAM B, and FM/AM-mono. NICAM A and B may belong either to a stereo or to a dual language transmission. Information about operation mode and about the quality of the NICAM signal can be read by the controlling software via the control bus. In the case of low quality (high bit error rate), the controlling software may decide to switch to the analogue FM/AM-mono sound. Alternatively, an automatic NICAM-FM/AM switching may be applied.

German 2-Carrier System (DUAL FM System)

Since September 1981, stereo and dual sound programs have been transmitted in Germany using th e 2carrier system. Sound transmission consists of the already existing first sound car r ier and a second sound carrier additionally containing an identification signal. More details of this standard are given in Tables below. For D/K very similar system is used.

FUNCTIONAL DESCRIPTION OF VIDEO PROCESSOR Vision IF amplifier

The vision IF amplifier can demodulate signals with positive and negative modulation. The PLL demodulator is completely alignment-free.

The VCO of the PLL circuit is internal and the frequency is fixed to the required value by using the clock frequency of the µ-Controller/Teletext decoder as a reference. The setting of the various frequencies is made by the controlling software in subaddress 27H (38.9 MHz for all system except L’ or 33.9 MHz for system L’). Because of the internal VCO the IF circuit has a high immunity to EMC interferences.

QSS Sound circuit

The sound IF amplifier is similar to the vision IF amplifier and has an external AGC decoupling capacitor.

The single reference QSS mixer is realised by a multiplier. In this multiplier the SIF signal is converted to the intercarrier frequency by mixing it with the regenerated picture carrier from the VCO. The mixer output signal is supplied to the output via a high-pass filter for attenuation of the residual video sig nals. With this system a high performance hi-fi stereo sound pr ocessing can be achieved.

Video switches

The video switch has one input for an external CVBS or Y/C signal. The selected CVBS signal can be supplied to pin 38, the IF video output. The selection between both signals is realised by the controlling software in subaddress 22H.

The video ident circuit is connected to the selected signal. This ident circuit is independent of the synchronisation.

Synchronisation circuit

The IC contains separator circuits for the horizontal and vertical sync pulses and a data-slicing circuit which extracts the digital teletext data from the analogue signal.

The horizontal drive signal is obtained from an internal VCO which is running at a frequency of 25 MHz. This oscillator is stabilised to this frequency by using a 12 MHz signal coming from the reference oscillator of the µ-Controller/Teletext decoder.

The horizontal drive is switched on and off via the soft start/stop procedure. This function is realised by means of variation of the TON of the horizontal drive pulses.

The vertical synchronisation is realised by means of a divider circuit. The vertical ramp generator needs an external resistor and capacitor. For the vertical drive a differential output current is available. The outputs are DC coupled to the vertical output stage.

In the type TDA9367, intended for 90° picture tubes the following geometry parameters can be adjusted:

•

Horizontal shift

•

Vertical amplitude

•

Vertical slope

•

S-correction

•

Vertical shift

The types which are intended to be used in combination with 110° picture tubes have an East-West control circuit. The additional controls for these types are:

•

EW width

•

EW parabola width

•

EW upper and lower corner parabola correction

•

EW trapezium correction

•

Vertical zoom, horizontal parallelogram and bow correction.

Chroma and luminance processing

The chroma band-pass and trap circuits (including the SECAM cloche filter) are realised by means of gyrators and are tuned to the right frequency by comparing the tuning frequency with the reference frequency of the colour decoder. The luminance delay line and the delay cells for the peaking circuit are also realised with gyrators. The circuit contains a black stretcher function which corrects the black level for incoming signals which have a difference between the black level and the blanking level.

Colour decoder

The ICs can decode PAL, NTSC and SECAM signals. The PAL/NTSC decoder does not need external reference crystals but has an internal clock generator which is stabilised to the required frequency by using the 12 MHz clock signal from the reference oscillator of the µ-Controller/Teletext decoder.

The Automatic Colour Limiting (ACL) circuit (switchable via the ACL bit in sub address 2OH) prevents that oversaturation occurs when signals with a high chroma-to-burst ratio are received. The ACL circuit is designed such that it only reduces the chroma signal and not the burst signal. This has the advantage that the colour sensitivity is not affected by this function.

SOFTWARE CONTROL

The CPU communicates with the peripheral functions using Special function Registers (SFRS) which are addressed as RAM locations. The registers for the Teletext decoder appear as normal SFRs in the µController memory map and are written to these functions by using a serial bus. This bus is controlled by dedicated hardware which uses a simple handshake system for software synchronisation.

For compatibility reasons and possible re-use of software blocks, the TV processor is controlled by I2C bus. The TV processor control registers cannot be read. Only the status registers can be read ( Read address 8A ).

- 23 -

Page 49

Appendix Service manual CP-795

The SECAM decoder contains an auto-calibrating PLL demodulator which has two references, via the divided 12 MHz reference frequency (obtained from the µ-Controller) which is used to tune the PLL to the desired free-running frequency and the bandgap reference to obtain the correct absolute value of the output signal. The VCO of the PLL is calibrated during each vertical blanking period, when the IC is in search or SECAM mode.

The base-band delay line (TDA 4665 function) is integrated. This delay line is also active during NTSC to obtain a good suppression of cross colour effects. The demodulated colour difference signals are internally supplied to the delay line.

RGB output circuit and black-current stabilisation

In the RGB control circuit the signal is controlled on contrast, brightness and saturation. The ICs have a linear input for external RGB signals. The signals for OSD and text are internally supplied to the control circuit. The output signal has an amplitude of about 2 Volts black-to-white at nominal input signals and nominal settings of the various controls.

To obtain an accurate biasing of the picture tube the 'Continuous Cathode Calibration’ system has been included in these ICs. A black level off set can be made with respect to the level which is generated by the black current stabilisation system. In this way differ ent colour temperatures can be obtained for the bright and the dark part of the picture. The black current stabilisation system checks the output level of the 3 channels and indicates whether the black level of the highest output is in a certain window or below or above this window. This indication is read from the status byte 01 and is used for automatic adjustment of the Vg2 voltage during the production of the TV receiver.

During switch-off of the TV receiver a fixed beam current is generated by the black current control circuit. This current ensures that the picture tube capacitance is discharged. During the switch-off period the vertical deflection is placed in an overscan position so that the discharge is not visible on the screen.

2-2 IF

The TDA936x has an alignment free IF PLL demodulator. Th e fully integrated oscillator is automatically calibrated, using the 12 MHz crystal as a frequency reference. The IF frequency is simply set in TVProcessor by I2C bus. The AFC information is available via I2C bus from the TV-Processor status bytes. The controlling software uses this information for tuner frequency tracking ( automatic following ). The AFC windows is typically 125Khz wide. The minimum frequency step of the tuner is 62.5 KHz. This AFC function is disabled when a program is tuned using the direct frequency entry or after fine tuning adjustment. Therefore it is recommended to tune channel with the TV search function ( manual or ATSS ) or using the direct channel entry to enable the Automatic Frequency Control.

- Channel 2 ( L, D/K, I, B/G) with one pass band for sound carriers between 32.40 MHz and 33.40 MHz

For SECAM L and L’ the TDA936x is switched to positive modulation via I2C bus. SECAM L’ only occur in VHF band I and have their picture and sound carrier interchanged, compared to SECAM L and PAL B/G channels. For SECAM L’ the picture carrier is situated at 33.9 MHz and the AM sound carrier at 40.40 MHz. The IF PLL reference is tuned from 38.9 to 33.9 MHz, this is done via I2C Bus and the SIF filter is switched from channel 2 to channel 1 ; this is done by pin 4 of TDA 936x. The tuner AGC time constant is slower than for negative modulation, because the TDA936x reduces its AGC current. To even slower the AGC time constant an extra series resistor R103 is added. To prevent IF overload when jumping from a very strong transmitter to a weak transmitter a diode D101 has been added The SAW filter ( SF1 ) has a double Nyquist slope at 38.9 MHz and 33.9 MHz needed for this multistandard application. The disadvantage of this choice is that a 5.5 MHz trap filter ( Z501 ) is needed to suppress the residual sound carrier in the video for B/G signals.

2-3 Source switching

The TDA936x has only one external video input, the external video switch ing circuit made with Q504, Q505, Q507, Q508 and Q509 allows 2 external video signal inputs. The switching command can be either the SCART1 slow switching pin 8 or the µ-Controller pin 8 when the software takes control of the video source. The µ-Controller pin 8 is automatically configured by the controlling software ( See table below ). This pin is also capable of detecting the 3 Status ( 0, 1A, 1B ) described in SCART specifications for automatic format switching.

AV 1 forced Output - Push Pull Max. 3.3V

AV 2 Output - Push Pull < 0.2 V

The controlling software via I2C bus selects the signal source :

- Video signal from tuner ( Pin 40 ).

- External video ( SCART 1 or 2 ) depending on Q508 base level.

- External SVHS from SCART 2.

The sound source switching is done in the MSP3415D ( I601 ), by the µ-Controller via I2C bus.

Fast R, G, B insertion : The external R, G, B insertion needs a fast switching and cannot be controlled b y the software ( instruction cycle of 1µ sec ). The fast switching pin 16 of SCART 1 is directly connected to the TV processor pin 45 ( Fast blanking input ). The display is synchronised with the selected video source, i.e. to get stable R, G, B inserted signal they must be synchronised with the selected video source. The controlling software only enable or disable ( AV2, SVHS, or Forced RF source selected ) fast blanking.

2-4 µ-Controller I/O pin configuration and function

The I/O pins of the µ-Controller can be configured in many way. All port functions can be individually programmed by use of the SFR registers. Each I/O port pin can be individually programmed in these configurations :

Open drain In this mode, the port can function as in and output. It requires an external pull-up resistor. The maximum allowable supply voltage for this pull up resistor is +5V. So in this mode it is possible to interface a 5 Volt environment like I2C while the µ-Controller has a 3.3 Volt supply.

Quadrature Mixers The digital input coming from the integrated A/D con v erter may contain audio information at a frequency range of theoretically 0 to 9 MHz corresponding to the selected standards. By means of two programmable quadrature mixers, two different audio sources ; for e xample, NICAM and FM-mono, may be shifted into baseband position.

Appendix Service manual CP-795

Phase and AM discrimination The filtered sound IF signals are demodulated by means of the phase and amplitude discriminator block. On the output, the phase and amplitude is available for further processing. AM signals are derived from the amplitude information, whereas the phase information serves for FM and NICAM demodulation.

NICAM decoder In case of NICAM - mode, the phase samples are decoded according the DQPSK - coding scheme. The output of this block contains the original NICAM bitstream.

DSP section All audio baseband functions are performed by digital signal processing (DSP). The DSP section controls the source and output selection, and the signals processing.

Sound Mode switching In case of NICAM transmission, the controlling software read the bit error rate and the operation mode from the NICAM Decoder. When the set is in “Auto detection” mode ( default mode after ATSS ) the controlling software set automatically the sound mode ( NICAM mono, NICAM Dual 1 or NICAM Dual 2 ) depending on the transmitted mode. In case of 2 Carrier FM transmission, the controlling software read the transmission mode and the signal quality level from the Stereo Detection Register. When the set is in “Auto detection” mode the contro lling software set automatically the sound mode ( mono, Stereo, Dual 1, Dual 2 ) depending on the transmitted mode. In “Auto detection” mode the controlling software evaluate the signal quality and automatically switch to the analogy sound carrier 1, if the transmission quality is too poor. To avoid unwanted automatic switching the threshold levels mono to stereo and stereo to mono is different. In “forced mono “ mode ( Red OSD in recall section ), the controlling software configure the MSP3415D to demodulate only the analogue (FM or AM) sound carrier 1, no matter the signal quality. The sound mode “ forced “ or “ Autodetect” is stored for each programme.

2-6 Sound amplification The TDA8944J (TDA8946J) is a stereo BTL audio amplifier capable of delivering 2 x 7 W (2 x 15 W) output power to an 8 Ω load at THD = 10%, using a 12 V power supply and an exter nal heatsink. The voltage gain is fixed at 32dB.

With the three-level MODE input the device can be switched from ‘standby’ to ‘mute’ and to ‘operating’ mode. The TDA 8944J outputs are protected by an internal thermal shutdown protection mechanism and shortcircuit protection.

Power amplifier The power amplifier is a Bridge Tied Load (BTL) amplifier with an all-NPN output stage, capable of delivering a peak output current of 1.5 A. The BTL principle offers the following advantages :

- Lower peak value of the supply current.

- The ripple frequency on the supply vo ltage is twice the signal frequency.

- No DC-blocking capacitor

- Good low frequency performance

Mode selection The TDA894xJ has several functional modes, which can be selected by applying the proper DC voltage to pin MODE.

Mute : In this mode the amplifier is DC biased but not operational (no audio output). This allows the input coupling capacitors to be charged to avoid pop-noise. The devices is in mute mode when 2.5 V < V (Vcc-1.5 V).

Operating : In this mode the amplifier is operating normally. The operating mode is activated at V

0.5 V.

2-7 Vertical deflection The vertical driver circuit is a bridge configuration. The deflection coil is connected between the output amplifiers, which are driven in phase opposition. The differential input circuit is voltage driven. The input circuit is especially intended for direct connection to driver circuits which deliver symmetrical current signals, but is also suitable for asymmetrical currents. The output current of these devices is converted to voltages at the input pins via resistors R350 and R351. The differential input voltage is compared with the output current through the deflection coils measured as voltage across R302, which provides internal feedback information. The voltage across R302 is proportional to the output current. Flyback voltage The flyback voltage is determined by an additional supply voltage V

. The principle of operation with

flb

two supply voltages (class G) makes it possible to fix the supply vo ltage Vp optimum for the scan voltage and the second supply voltage V efficiency is achieved. The supply voltage V

optimum for the flyback voltage. Using this method, very high

- overvoltage of output stage A

The guard signal is not used by the TDA936x to blank the screen in case of fault condition.

Damping resistor For HF loop stability a damping resistor (R305) is connected across the deflection coil.

EAST-WEST Amplifier (TDA8358J only) The East-West amplifier is current driven. It can only sink currents of the diode modulator circuit. A feedback resistor R397 is connected between the input and output of this inverting amplifier in order to convert the East-West correction input into an output voltage.

When the MOSFET turns OFF, charging of STR-F6653 internal capacitor C1 is released and C1 starts discharging by the STR-F6653 internal resistance R1. So, C1 voltage starts falling in accordance with the gradient regulated by the constant discharging time of C1 and R1. So, this means that the fixed time determined by C1 and R1 is the OFF-time of the MOSFET.

When C1 voltage falls to around 3.7V, the STR-F6653 internal oscillator is reversed again and the MOSFET turns ON. C1 is quickly charged to around 6.5V

The MOSFET continues to oscillate by repeating the above procedure.

2-9-1-2 TV start-up and microcontroller initialization

- When SW801 power switch is pushed, main AC voltage is applied to T801 transformer (after

rectification by D801...D804 diodes). Then, T801 SMPS transformer starts operating and supplies DC voltage to I823 (3.3V regulator).

- This regulator provides 3.3V DC voltage to I501 microcontroller power supply pins (pins 54, 56, 61) and

to the reset pulse circuit which provides reset pulse to I501 microcontroller reset pin (pin 60).

- Then, the microcontroller starts its initialization. Its power pin (p in 63) is set to high which allows

delivery of power supply voltages (123V, 8V, 5V...). At this step, all IC’s start working but no picture appears on screen: I501 IC doesn’t provide horizontal drive voltage.

- Then, the microcontroller consults I702 EEPROM via I2C bus to know the last TV set mode (normal run

mode or stand-by mode ) before switching off.

If the TV set was on normal run mode before switching off, the microcontroller delivers

horizontal drive voltage at pin 33 and picture appears on screen.

If the TV set was on stand-by mode before switching off, the microcontroller sw itches TV set to

stand-by mode, decreasing power pin voltage (pin 63). this matter will be explained on paragraph 5-9-2-b.

2-9-1-3 Reset pulse circuit:

2-9-1-4 Reset pulse circuit operations description

- When DC supply voltage from I823 regulator starts rising (from 0V to 1.2V), no current flows through

D591 zener diode. So, Q510 is in off mode. Also V

=Vcc/2 -Vcc = -Vcc/2 > -0.6V. So, Q511 is in off mode.

be Q511

Then, no voltage reaches I501 pin 60.

- When this voltage reaches 1.2 V, Q510 stays in off mode

but V

= -0.6V. So, Q511 is switched on and starts driving DC supply voltage to I501 pin 60.

Appendix Service manual CP-795

- When the DC supply voltage reaches (2.4V +0.6V ) =3.0V, Q510 starts conducting but as the Q511

base-emitter voltage is the same as the collector-emitter voltage of the saturated Q510, Q511 switches off and no voltage reaches I501 pin 60.

- If the DC supply voltage decreases below 3 V, Q510 switches off immediately. Q511 starts conducting,

pulling I501 pin 60 high. At the same time, it discharges the reset capacitor C501. Discharging this capacitor is necessary to garantee a defined reset pulse duration.

2-9-2 TV normal run and stand-by mode operations

Depending on remote control commands, I501 microcontroller part pin 63 (power) is set to:

- high for normal run mode

- low for stand-by mode

Appendix Service manual CP-795

On normal run mode, I501 microcontroller pin 63 (power) is set to high

•

So, I810 controlled rectifier is not conducting

- Q809 is conducting. So, Q808 is not conducting and Q807 is conducting

- So, Q807 collector is connected to the ground and I810 controlled rectifier gate pin is set to low (no conducting)

•

So, current from 11V DC voltage (from T801 SMPS transformer pin 13) does not flow through Q811 and Q810 transistors but flows through I806 IC error amplifier

- Q809 is conducting. So, Q810 is not conducting and no current flows from Q810 collector to the ground

Therefore, the power circuit diagram is the following one:

2-9-2-1-3 power supply functioning during T V set normal run mode

- I801 transmits controlled pulses to T801 which generates DC voltages after rectifications by secondary part diodes and electro capacitors (by example by D820 and C813 on 1 43V supply voltage line).

- 8V, 5V, 3.3V supply voltage lines have stabilized voltages obtained by I8 20, I822, I823 voltage regulators.

- On 143V supply voltage line, R823 resistor has been chosen to reach exact DC voltage required on this line.

- 143V supply voltage line includes an IC error amplifier (I806) which corrects unexpected DC voltage variations on this line.

2-9-2-2-2 TV set stand-by mode operations

-On stand-by mode, I501 microcontroller pin 63 (power) is set to low.

- So, Q809 collector is set to high.

-Then, I810 controlled rectifier gate pin is set to high and I810 is conducting.

- So, current flows from pin 16 SMPS transformer to the ground via I804 photo coupler and Q810 and

Q811 transistors (which are conducting).

- In these conditions, I801 delivers pulses on light mode and T801 produces voltages with reduced power.

- As I810 is conducting, current flows also from pin 16 SMPS transformer to I823 (3.3V regulator) for

I501 µcom, IR receiver and front mask buttons supply voltage (then, remote control or front mask buttons can be activated to leave stand-by mode).
