KEYBOARD
All the keys on the keyboard are used same as the relevant keys on the RC. But navigation in menus is quite differ­ent. In order to open Main Menu from keyboard V+ and V- keys must be pressed together. After displaying the menus P+ and P- keys will be used as Navigation Up and Navigation Down keys. There is no enter key on the key­board so V+ or V- will be used as Menu Right key if a submenu item is highlighted on the menu. These two keys will also be used as Navigation Left and Navigation Right keys in order to change any highlighted options right side value. To return previous menu V+ and V- keys should be pressed together.
2. SAFETY INSTRUCTIONS AND WARNINGS
SAFETY INSTRUCTIONS FOR SERVICE REPAIRS
1. Use only the original spare parts with the same specifi­cations for replacement.
2. Only the original fuse value should be used.
3. Safety components, indicated by the symbol, should be replaced by components identical to the original ones.
4. Main leads and connecting leads should be checked for external damage before connection. Insulation must be checked.
5. Parts contributing to the safety of the product must not be damaged or obviously unsuitable. This is valid especial­ly for insulators and insulating parts.
6. Thermally loaded solder pads are to be sucked off and re-soldered.
7. Ensure that the ventilation slots are not obstructed.
8. Potentials as high as 25 KV are present when this receiver is operating. Operation of the receiver outside the cabinet or with back cover removed involve a shock hazard from the receiver.
9. Servicing should not be attempted by anyone who is not thoroughly familiar with precautions necessary when work­ing on high voltage equipment. Perfectly discharge the high potential of the picture tube before handling it. The picture tube is highly evacuated and if broken. Glass frag­ments will be violently expelled. Always discharge the pic­ture tube anode to the receiver chassis to keep of the shock hazard before removing the anode cap.
10. Keep wire away from the high voltage or high tempera­ture components.
11. When replacing a wattage resistor, keep the resistor 10mm away from the circuit board.
12. Fast heating up (e.g. by bringing the Combi from a cold place into warm and humid room) can result in moisture condensing on the pickup lens of the DVD Module, thus influencing the playability for a certain time. Before check­ing the performance, the DVD Loader should be stabilized for at least 4 hours.
13. Never try to repair DVD module when it is ON. The
laser beam is highly dangerous and it may cause perma­nent damages.
HANDLING THE MOS CHIP COMPONENTS
MOS circuit requires special attention with regard to static charges. Static charges may occur with any highly insulat­ed plastics and can be transferred to persons wearing clothes and shoes made of synthetic materials. Protective circuits on the inputs and outputs of MOS circuits give pro­tection to a limited extend only due to time of reaction.
Please observe the following instructions to protect the components against ESD.
1. Keep MOS components in conductive package until they are used. Most components must never be stored in styro­por materials or plastic magazines.
2. Personnel must not touch the MOS components to avoid electrostatic discharging.
3. Hold the component by the body touching the terminals.
4. Use only grounded instruments for testing and process­ing purposes.
5. Remove or connect MOS Ics when operating voltage is disconnected.
6. Personnel in charge must make sure that they are con­nected with the same potential as the mass of the set by a wristband with resistance.
X-RAY RADIATION PRECAUTION
1. Excessive high voltage can produce potentially haz­ardous X-RAY radiation. To avoid such hazard, the high voltage must not be above the specified limit. The nominal value of the high voltage of this receiver is 25KV at zero beam current (minimum brightness) under 220 V AC power source. The high voltage must not under any circumstance, exceed 30KV. It is recommended the reading of the high voltage to be recorded as a part of the service record. It is important to use an accurate and reliable high voltage meter.
2. The primary source of X-RAY radiation in the 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 part list.

9.1 SAFETY AND HANDLING PRECAUTIONS
1. DO NOT use and store the Loader in dusty, high temperature or high humidity environments.
2. To avoid damage to the Loader by electrostatic dischargers, measuring equipment and operators should be
grounded during handling. The user of this unit takes all necessary precautions to avoid ESD (Electro-Static Discharge) failures during handling and assembly of this unit into the end product.
3. Contamination of the PCB might influence the performance. Avoid fingerprints and stains on the PCB and
handle the Loader in a clean environment.
4. The mechanism of the Loader has been adjusted carefully during manufacturing. High shocks on this unit
may damage and should be avoided.
5. Fast heating (e.g. by bringing the Loader unit from a cold place into a warm and humid room) can result in
moisture condensing on the pickup lens, thus influencing the playability for a certain time. Before checking the performance the Loader unit should be stabilized for at least 4 hours.
6. DO NOT disamble the loader to avoid ESD failures and to prevent from contamination.

ST92185 No-teletext
ST92195 With teletext
The ST92195 microcontroller is developed and manufac­tured by STMicroelectronics using a pro-prietary n-well HCMOS process. Its performance derives from the use of a flexible 256-register pro-gramming model for ultra-fast context switching and real-time event response. The intelli­gent on-chip peripherals offload the ST9 core from I/O and data management processing tasks allowing critical appli­cation tasks to get the maximum use of core resources. The ST92195 MCU supports low power consumption and low voltage operation for power-efficient and low-cost embedded systems.
The advanced ST9+ Core consists of the Central Process­ing Unit (CPU), the Register File and the Interrupt con­troller. The general-purpose registers can be used as accu­mulators, index registers, or address pointers. Adjacent register pairs make up 16-bit registers for addressing or 16-bit processing. Although the ST9 has an 8-bit ALU, the chip handles 16-bit operations, including arithmetic, loads/stores, and memory/register and memory/memory exchanges. Two basic addressable spaces are available: the Memory space and the Register File, which includes the control and status registers of the on-chip peripherals. Power consumption of the device can be reduced by more than 95% (Low power WFI).
Up to 28 I/O lines are dedicated to digital Input/Output. These lines are grouped into up to five I/O Ports and can be configured on a bit basis under software control to pro­vide timing, status signals, timer and output, analogue inputs, external interrupts and serial or parallel I/O. A set of on-chip peripherals form a complete system for TV set and VCR applications:

Non-Volatile Memory
These I_C-compatible electrically erasable programmable memory (E_PROM) is organized as 1024 x 8 bit and operate with a power supply of 5 V. The memory behaves as a slave device in the I_C protocol, with all memory operations syn­chronized by the serial clock. Read and Write operations are initiated by a START
condition, generated by the bus master. The START condition is followed by a Device Select Code and RW bit terminated by an acknowledge bit.

Description
The TDA 16846 is optimised to control free running or fixed frequency flyback converters with or without Power Factor Correction (Current Pump). To provide low power consumption at light loads, this device reduces the switching frequency continuously with load, towards an adjustable minimum (e. g. 20 kHz in standby mode). Additionally, the start up current is very low. To avoid switching stresses of the power devices, the power tran­sistor is always switched on at minimum voltage. A spe­cial circuit is implemented to avoid jitter. The device has several protection functions: V CC over- and undervolt­age, mains undervoltage, current limiting and 2 free usable fault comparators. Regulation can be done by using the internal error amplifier or an opto coupler feed­back (additional input). The output driver is ideally suited for driving a power MOSFET, but it can also be used for a bipolar transistor. Fixed frequency and synchronized operation are also possible. The TDA 16846 is suited for TV-, VCR- sets and SAT receivers. It also can be good used in PC monitors. The TDA 16847 is identical with TDA 16846 but has an additional power measurement output (pin 8) which can be used for a Temporary High Power Circuit.

Short Description of the Pin Functions
Pin Functions
1 A parallel RC-circuit between this pin and ground determines the ringing suppression time
and the standby-frequency.
2 A capacitor between this pin and ground and a resistor between this pin and the positive
terminal of the primary elcap quantifies the max. possible output power of the SMPS.
3 This is the input of the error amplifier and the zero crossing input. The output of a voltage
divider between the control winding and ground is connected to this input. If the pulses at pin 3 exceed a 5 V threshold, the control voltage at pin 4 is lowered.
4 This is the pin for the control voltage. A capacitor has to be connected between this pin
and ground. The value of this capacitor determines the duration of the softstart and the speed of the control.
PT 90 NEAT Service Manual
5 If an opto coupler for the control is used, it's output has to be connected between this pin
and ground. The voltage divider at pin 3 has then to be changed, so that the pulses at pin 3 are below 5 V.
6 Fault comparator 2: If a voltage > 1.2 V is applied to this pin, the SMPS stops.
7 If fixed frequency mode is wanted, a parallel RC circuit has to be connected between this
pin and ground. The RC-value determines the frequency. If synchronized mode is wanted, sync pulses have to be fed into this pin.
8 Not connected (TDA16846). / This is the power measurement output of the Temporary
High Power Circuit. A capacitor and a RC-circuit has to be connected between this pin and ground.
9 Output for reference voltage (5 V). With a resistor between this pin and ground the fault
comparator 2 (pin 6) is enabled.
10 Fault comparator i: If a voltage > 1 V is applied to this pin, the SMPS stops.
11 This is the input of the primary voltage check. The voltage at the anode of the primary
elcap has to be fed to this pin via a voltage divider. If the voltage of this pin falls below 1 V, the SMPS is switched off. A second function of this pin is the primary voltage depen­dent fold back point correction (only active in free running mode).
12 Common ground.
13 Output signal. This pin has to be connected across a serial resistor with the gate of the
power transistor.
14 Connection for supply voltage and startup capacitor. After startup the supply voltage is
produced by the control winding of the transformer and rectified by an external diode.

FUNCTIONAL DESCRIPTION
The TDA7057AQ is a stereo output amplifiers with two DC volume control stages. The device is designed for TV and monitors, but also suitable for battery-fed portable re­corders and radios.
In conventional DC volume control circuits the control or input stage is AC coupled to the output stage via external capacitors to keep the offset voltage low.
In the TDA7057AQ the two DC volume control stages are integrated into the input stages so that no coupling capa­citors are required and a low offset voltage is still mainta­ined. The minimum supply voltage also remains low.
The BTL principle offers the following advantages:
• Lower peak value of the supply current
• The frequency of the ripple on the supply voltage is twi­ce the signal frequency.
Consequently, a reduced power supply with smaller capa
citors can be used which results in cost reductions.
For portable applications there is a trend to decrease the supply voltage, resulting in a reduction of output power at conventional output stages. Using the BTL principle incre­ases the output power.
The maximum gain of the amplifier is fixed at 40.5 dB. The DC volume control stages have a logarithmic control characteristic. Therefore, the total gain can be controlled from +40.5 dB to -33 dB. If the DC volume control voltage falls below 0.4 V, the device will switch to the mute mode.
The amplifier is short-circuit protected to ground, Vp and across the load. A thermal protection circuit is also imple­mented. If the crystal temperature rises above 150 oC the gain will be reduced, thereby reducing the output power.
Special attention is given to switch-on and switch-off
clicks, low HF radiation and a good overall stability.

LM317 pos: IP02
1.2V TO 37V Voltage Regulator
GENERAL DESCRIPTION
The LM117 series of adjustable 3-terminal positive vol­tage regulators is capable of supplying in excess of 1.5A over a 1.2V to 37V output range. They are exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulati­on are better than standard fixed regulators. Also, the LM117 is packaged in standard transistor packages which are easily mounted and handled. In addition to higher performance than fixed regulators, the LM117 series offers full overload protection availab­le only in IC’s. Included on the chip are current limit, thermal overload protection and safe area protection. All overload protection circuitry remains fully functional even if the adjustment termi-nal is disconnected. Normally, no capacitors are needed unless the device is situ-ated more than 6 inches from the input filter capaci­tors in which case an input bypass is needed. An opti­onal output capacitor can be added to improve transient response. The adjustment terminal can be bypassed to achieve very high ripple rejection ratios which are diffi­cult to achieve with stan-dard 3-terminal regulators. Besides replacing fixed regulators, the LM117 is useful in a wide variety of other applications. Since the regula­tor is “floating” and sees only the input-to-output diffe­rential volt- age, supplies of several hundred volts can be regulated as long as the maximum input to output dif­ferential is not ex-ceeded, i.e., avoid short-circuiting the output. Also, it makes an especially simple adjustable switching regulator, a programmable output regulator, or by connecting a fixed resistor between the adjust­ment pin and output, the LM117 can be used as a pre­cision current regulator. Sup-plies with electronic shut­down can be achieved by clamping the adjustment ter­minal to ground which programs the out-put to 1.2V where most loads draw little current. For applications re­quiring greater output current, see LM150 series (3A) and LM138 series (5A) data sheets. For the negative complement, see LM137 series data sheet.

DESCRIPTION
Built on ESS’s proprietary and flexible Programmable Multi­media Processor architecture, the Vibratto TM series of DVD processors combine audio/video stream data process­ing, system control and housekeeping functions, video post­processing, and display format encoding, enabling various DVD-based multimedia electronics to be built with minimal external components. The Vibratto series includes new fea­tures for DVD-Audio support, progressive scan video out­put, and built-in TV encoder and video DACs.
All of the Vibratto DVD processors each include two parallel processing units, a RISC processor, a vector engine, and supplemental hardware resources for implementing special­ized encoding and decoding tasks in the device architec­tures. All of these resources are interconnected with two separate data buses, each with its own DMA unit and inter­face to external memory. The processing units enable simultaneous parallel execution of system commands and data processing.
Both the RISC processor and vector engine are indepen­dently programmable. Each has its own on-chip cache memory. The RISC processor and its associated hardware units perform bit stream parsing, control audio data output, transfer video and audio data to the vector engine and ser­vice system control and housekeeping functions. The vector engine and associated hardware units perform audio and video microcode processing required by A/V standards such as Dolby Digital TM, DTS TM, MPEG and JPEG. These processing tasks include audio DSP, video motion compen­sation and estimation, loop filtering, discrete cosine trans­forms (DCT) and inverse DCT, quantization and inverse quantization.
The Vibratto DVD processors support both JPEG/MP3 audio playback and the Kodak PictureCD JPEG display for­mat. These new features allow Picture CDs created with images and voiceovers from digital cameras to be enjoyed in a DVD player or Home Theater System.
