IMPORTANT SERVICING NOTES

Only qualified service personnel are allowed to carry out maintenance and repair of this receiver.

Servicing of High Voltage System and CRT

It is important that the static charge is removed from the high voltage system when carrying out work on thereceiver. This can be achieved by connecting a 10K resistor (with a suitably insulated lead) from the CRTcavity connector to the CRT ground tag. This must be carried out with the AC supply disconnected from thereceiver.

Note the following:

• The CRT in this receiver employs Integral Implosion Protection.• If the CRT has to be changed it MUST be replaced with the correct type for continued safe working.• DO NOT lift the CRT by its neck.• When handing the CRT, ensure that shatterproof goggles are worn.• Ensure that the CRT is discharge before handling.

X-Ray

This receiver is designed to keep any x-ray emission to an absolute minimum. Some fault conditions andservicing procedures may produce potentially hazardous x-ray radiation levels. This is a problem when inclose proximity to the receiver for long periods of time. To reduce any risks associated with this, pleaseobserve the following precautions:

1. When undertaking any servicing on this chassis, DO NOT increase the EHT to more than 27.5 KV, (at ainstantaneous beam current of 1000 µA).

2. Ensure that during normal operation the EHT does not exceed 25.6 KV (at a beam current of 800 µA).This level has been preset in the factory. Always check that this level has not been exceeded aftercarrying out any repair on the receiver.

3. DO NOT replace the CRT with any other type than that specified in the parts listing as this may causeexcessive x-ray radiation.

Before returning the receiver to the customer

In addition to the above checks, the following should also be carried out before returning the receiver to thecustomer.

1. Inspect all the leads to ensure that they are dressed correctly and that they are not obstructed or pinchedby any other parts.

2. Ensure that all protective devices are in good condition. These will include nonmetallic control knobs,insulating fish papers, cabinets backs, compartment covers or shields, mechanical insulators, etc.

1 Introduction

11AK36 is a 90º chassis capable of driving 14" tubes at the appropriate currents. The chassis is capable of operating inPAL, SECAM and NTSC standards. The sound system is capable of giving 3 watts RMS output into a load of 16 ohms.One page and US Closed Caption is also provided. The chassis is equipped with a 21 pin Eu-Scart connector.

2 Small Signal Part With STV2248:

STV2248 video processor is essential for realizing all small signal functions for a colour TV receiver.2.01 Vision IF AmplifierThe vision IF amplifier can demodulate signals with positive and negative modulation. The PLL demodulator iscompletely alignment-free. Although the VCO (Toko-coil) of the PLL circuit is external, yet the frequency is fixed tothe required value by the original manufacturer thus the Toko-col1 does not need to be adjusted manually. Thesetting of the various frequencies (38.9 or 4575 MHz) can be made via changing the coil itself.

2.02 QSS Sound Circuit (QSS Versions)The sound IF amplifier is similar to the vision IF amplifier and has an external AGC de-coupling capacitor. The singlereference QSS mixer is realised by a multiplier. In this multiplier the CIF signal is converted to the inter-carrierfrequency by mixing it with the regenerated picture carrier from the VCO. The mixer output signal is supplied to theoutput via a high-pass filter for attenuation of the residual video signals. With this system a high performance hi-fistereo sound processing can be achieved. The AM sound demodulator is realised by a multiplier. The modulatedsound IF signal is multiplied in phase with the limited SIF signal. The demodulator output signal is supplied to theoutput via a low-passfilter for attenuation of the carrier harmonics. The AM signal is supplied to the output via thevolume control.

2.03 AM DemodulatorThe AM demodulated signal results from multiplying the input signal by itself, it is available on AM/FM output.

2.04 FM Demodulator and Audio Amplifier (Mono Versions):The FM demodulator is realized as narrow-band PLL with external loop filter, which provides the necessary selectivitywithout using an external band-pass filter. To obtain a good selectivity a linear phase detector and constant inputsignal amplitude are required. For this reason the inter-carrier signal is internally supplied to the demodulator via again controlled amplifier and AGC circuit. The nominal frequency of the demodulator is tuned to the required frequency(4,5/5.5/6.0/6.5 MHz) by means of a calibration circuit that uses the clock frequency of the microcontroller/Teletextdecoder as a reference. The setting to the wanted frequency is realized by means of the software. It can be readwhether the PLL frequency is inside or outside the window and whether the PLL is in lock or not. With this informationit is possible to make an automatic search system for the incoming sound frequency. This is realized by means of asoftware loop that alternate the demodulator to various frequencies, then select the frequency on which a lockcondition has been found. De-emphasis output signal amplitude is independent of the TV standard and has thesame value for a frequency deviation of ±25 kHz at the 4.5 MHz standard and for a deviation of ±50 kHz for the otherstandards. When the IF circuit is switched to positive modulation the internal signal on de-emphasis pin is automaticallymuted. The audio control circuit contains an audio switch and volume control. In the mono inter-carrier sound versionsthe Automatic Volume Leveling (AVL) function can be activated. The pin to which the external capacitor has to beconnected depends on the IC version. For the 900 types the capacitor is connected to the EW output pin (pin 20).When the AVL is active it automatically stabilizes the audio output signal to a certain level.

2.05 Video SwitchingThe video processor (STV2248C) has three CVBS inputs and two RGB inputs. The first CVBS input is used forexternal CVBS from SCART 1, the second is used for either CVBS from FAV, and the third one is used for internalvideo. The selection between both external video inputs signals is realized by means of software switches.

2.06 Synchronization CircuitThe video processor (STV224X) performs the horizontal and vertical processing. The external horizontal deflectioncircuit is controlled via the Horizontal output pulse (HOUT). The vertical scanning is performed through an externalramp generator and a vertical power amplifier IC controlled by the Vertical output pulse (VOUT).The main components of the deflection circuit are:

PLL1 : the first phase locked loop that locks the internal line frequency reference on the CVBS input signal. It iscomposed of an integrated VCO (12 MHz) that requires the chroma Reference frequency (4.43MHz or 3.58MHzcrystal oscillator reference signal), a divider by 768, a line decoder, and a phase comparator.

AK - 36CHASSIS

PLL2: The second phase locked loop that controls the phase of the horizontal output (Compensation of horizontaldeflection transistor storage time variation). Also the horizontal position adjustment is also performed in PLL2.A vertical pulse extractor.A vertical countdown system to generate all vertical windows (vertical synchronization window, frame blankingpulses, 50/ 6OHz identification window ...).Automatic identification of 50/60Hz scanning.PLL1 time constant control.Noise detector, video identification circuits, and horizontal coincidence detector.Vertical output stage including de-interlace function, vertical position control.Vertical amplitude control voltage output (combined with chroma reference output and Xtal 1 indication).

2.07 Chroma and Luminance Processing:The chroma decoder is able to demodulate PAL, NTSC and SECAM signals.The decoder dedicated to PAL and NTSC sub-carrier is based on a synchronous demodulator, and a Xtal PLLlocked on the phase reference signal (burst). The SECAM demodulation is based on a PLL with automatic calibrationloop. The colour standard identification is based on the burst recognition. Automatic and forced modes can beselected through the I2C bus. NTSC tint, and auto flesh are controlled through 12C bus. Xtal PLL can handle up to 3crystals to work in PAL M, PAL N and NTSC M for South America. ACC an ACC overload control the chroma sub-carrier amplitude within 26dB range. Both ACCs are based on digital systems and do not need external capacitor. Allchroma filters are fully integrated and tuned via a PLL locked on Xtal VCO signal.A second PLL is used for accurate fine-tuning of the SECAM bell filter. This tuning is achieved during the frameblanking. An external capacitor memorizes the bell filter tuning voltage. A base-band chroma delay-line rebuilds themissing colour line in SECAM and removes transmission phase errors in PAL. The base-band chroma delay line isclocked with 6MHz signal provided by the horizontal scanning VCO. The luminance processor is composed of achroma trap filter, a luminance delay line, a peaking function with noise coring feature, a black stretch circuit. Trapfilter and luminance delay lines are achieved with the use of bi-quad integrated filters, auto-aligned via a master filterphase locked loop.

2.08 RGB output circuit:The video processor performs the R, G, B processing. There are three sources:

1. Y,U,V inputs (coming from luma part (Y output), and chroma decoder outputs (R-Y, B-Y outputs).2. External R,G,B inputs from SCART (converted internally in Y,U,v), with also the possibility to input YUVsignals from a DVD player, (YUV specification is Y=0.7 V PP , U= 0.7 V PP , V = 0,7V PP for 100% colour bar.)3. Internal R,G,B inputs (for OSD and Teletext display.)

The main functions of the video part are:- Y,U,V inputs with integrated clamp loop, allowing a DC link with YUV outputs,- External RGB inputs (RGB to YUV conversion), or direct YUV inputs,- Y,U,V switches,- Contrast, saturation, brightness controls,- YUV to RGB matrix,- OSD RGB input stages (with contrast control),- RGB switches,-APR function,- DC adjustment of red and green channels,- Drive adjustments (R, G, B gain),- Digital automatic cut-off loop control,- Manual cut-off capability with 12C adjustments,- Half tone, oversize blanking, external insertion detection, blue screen,- Blanking control and RGB output stages.

It also controls the video processor, the audio processor, and the tuner. Thecircuits just mentioned are controlled via the I²C bus. Also IC501 controls the video source switching, vertical positionadjustment and the vertical linearity adjustment via its ports.An external 8K EEPROM is used by the micro. The EEPROM comes fully programmed. The main clock oscillator is4.0 MHz crystal X501 on pins 50 and 51. Reset is provided on pin 2 via Q504. On switching on pin 2 becomes highand the controller gets reset which stays valid till a low signal comes on that pin.

2.09.01 ControlsCommand information from the infrared remote controller is fed through the sensor IC502 to pin 1 of the micro-processor. Operation of the customer front panel keys is detected by pin 8 that is an ADC (analogue to digitalconverter). Pressing a switch will connect the 5V to the ground through a particular resistor that determines thevalue of the voltage on pin 8 at that instant. This obtained value is comprehended by the micro and the correspond-ing operation is performed. Refer to the following table:

10.06 UC3842/3General description:The UC3842/3/4/5 family of control ICs provides the necessary features to implement off-line or DC to DC fixedfrequency current mode control schemes with a minimal external parts count. Internally implemented circuits includeunder voltage lockout featuring start-up current less than 1 mA, a precision reference trimmed for accuracy at theerror amp input, logic to insure latched operation, a PWM comparator which also provides current limit control, anda totem pole output stage designed to source or sink high peak current. The output stage, suitable for driving N-Channel MOSFETs, is low in the off-state. Differences between members of this family are the under-voltage lockoutthresholds and maximum duty cycle ranges. The UC3842 and UC3844 have UVLO thresholds of 16V (on) and 10V(off), ideally suited off-line applications The corresponding thresholds for the UC3843 and UC3845 are 8.5 V and 7.9V. The UC3842 and UC3843 can operate to duty cycles approaching 100%. A range of the zero to <50 % is obtainedby the UC3844 and UC3845 by the addition of an internal toggle flip flop which blanks the output off every otherclock cycle.
