SAFETY INSTRUCTIONS FOR SERVICEREPAIRS1. Use only the original spare parts with the same specifi-cations for replacement.2. Only the original fuse value should be used.3. Safety components, indicated by the symbol, shouldbe replaced by components identical to the original ones.4. Main leads and connecting leads should be checked forexternal damage before connection. Insulation must bechecked.5. Parts contributing to the safety of the product must notbe damaged or obviously unsuitable. This is valid especial-ly for insulators and insulating parts.6. Thermally loaded solder pads are to be sucked off andre-soldered.7. Ensure that the ventilation slots are not obstructed.8. Potentials as high as 25 KV are present when thisreceiver is operating. Operation of the receiver outside thecabinet or with back cover removed involve a shock hazardfrom the receiver.9. Servicing should not be attempted by anyone who is notthoroughly familiar with precautions necessary when work-ing on high voltage equipment. Perfectly discharge thehigh potential of the picture tube before handling it. Thepicture tube is highly evacuated and if broken. Glass frag-ments will be violently expelled. Always discharge the pic-ture tube anode to the receiver chassis to keep of theshock hazard before removing the anode cap.10. Keep wire away from the high voltage or high tempera-ture components.11. When replacing a wattage resistor, keep the resistor10mm away from the circuit board.12. Fast heating up (e.g. by bringing the Combi from a coldplace into warm and humid room) can result in moisturecondensing on the pickup lens of the DVD Module, thusinfluencing the playability for a certain time. Before check-ing the performance, the DVD Loader should be stabilizedfor 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 perma-nent damages.

HANDLING THE MOS CHIP COMPONENTSMOS circuit requires special attention with regard to staticcharges. Static charges may occur with any highly insulat-ed plastics and can be transferred to persons wearingclothes and shoes made of synthetic materials. Protectivecircuits on the inputs and outputs of MOS circuits give pro-tection to a limited extend only due to time of reaction.Please observe the following instructions to protect thecomponents against ESD.1. Keep MOS components in conductive package until theyare used. Most components must never be stored in styro-por materials or plastic magazines.2. Personnel must not touch the MOS components to avoidelectrostatic discharging.3. Hold the component by the body touching the terminals.4. Use only grounded instruments for testing and process-ing purposes.5. Remove or connect MOS Ics when operating voltage isdisconnected.6. Personnel in charge must make sure that they are con-nected with the same potential as the mass of the set by awristband with resistance.

X-RAY RADIATION PRECAUTION1. Excessive high voltage can produce potentially haz-ardous X-RAY radiation. To avoid such hazard, the highvoltage must not be above the specified limit. The nominalvalue of the high voltage of this receiver is 25KV at zerobeam current (minimum brightness) under 220 V AC powersource. The high voltage must not under any circumstance,exceed 30KV. It is recommended the reading of the highvoltage to be recorded as a part of the service record. It isimportant to use an accurate and reliable high voltagemeter.2. The primary source of X-RAY radiation in the TV receiv-er is the picture tube. For continued X-RAY radiation pro-tection, the replacement tube must be exactly the sametype tube as specified in the part list.

KEYBOARD

All the keys on the keyboard are used same as the relevant keys on the RC. But navigation in menus is quite differ-ent. In order to open Main Menu from keyboard V+ and V- keys must be pressed together. After displaying themenus P+ and P- keys will be used as Navigation Up and Navigation Down keys. There is no enter key on the key-board so V+ or V- will be used as Menu Right key if a submenu item is highlighted on the menu. These two keys willalso be used as Navigation Left and Navigation Right keys in order to change any highlighted options right sidevalue. To return previous menu V+ and V- keys should be pressed together.

The ST92195 microcontroller is developed and manufac-tured by STMicroelectronics using a pro-prietary n-wellHCMOS process. Its performance derives from the use ofa flexible 256-register pro-gramming model for ultra-fastcontext switching and real-time event response. The intelli-gent on-chip peripherals offload the ST9 core from I/O anddata management processing tasks allowing critical appli-cation tasks to get the maximum use of core resources.The ST92195 MCU supports low power consumption andlow voltage operation for power-efficient and low-costembedded systems. The advanced ST9+ Core consists of the Central Process-ing Unit (CPU), the Register File and the Interrupt con-troller. The general-purpose registers can be used as accu-mulators, index registers, or address pointers. Adjacentregister pairs make up 16-bit registers for addressing or16-bit processing. Although the ST9 has an 8-bit ALU, thechip handles 16-bit operations, including arithmetic,loads/stores, and memory/register and memory/memoryexchanges. Two basic addressable spaces are available:the Memory space and the Register File, which includesthe control and status registers of the on-chip peripherals.Power consumption of the device can be reduced by morethan 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 canbe configured on a bit basis under software control to pro-vide timing, status signals, timer and output, analogueinputs, external interrupts and serial or parallel I/O.

DescriptionThe TDA 16846 is optimised to control free running orfixed frequency flyback converters with or without PowerFactor Correction (Current Pump). To provide low powerconsumption at light loads, this device reduces theswitching frequency continuously with load, towards anadjustable minimum (e. g. 20 kHz in standby mode).Additionally, the start up current is very low. To avoidswitching stresses of the power devices, the power tran-sistor is always switched on at minimum voltage. A spe-cial circuit is implemented to avoid jitter. The device hasseveral protection functions: V CC over- and undervolt-age, mains undervoltage, current limiting and 2 freeusable fault comparators. Regulation can be done byusing the internal error amplifier or an opto coupler feed-back (additional input). The output driver is ideally suitedfor driving a power MOSFET, but it can also be used fora bipolar transistor. Fixed frequency and synchronizedoperation are also possible. The TDA 16846 is suited forTV-, VCR- sets and SAT receivers. It also can be goodused in PC monitors. The TDA 16847 is identical withTDA 16846 but has an additional power measurementoutput (pin 8) which can be used for a Temporary HighPower 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.

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 depen-dent 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.

QUICK REFERENCE DATA

TDA7057AQ2 x5 W stereo BTL Audio Output Amplifier with DC Volume Control

FEATURES DC volume control Few external components Mute mode Thermal protection Short-circuit proof No switch-on and switch-off clicks Good overall stability Low power consumption Low HF radiation ESD protected on all pins.

GENERAL DESCRIPTIONThe TDA7057AQ is astereo BTL output amplifier with DCvolume control. The device is designed for use in TV andmonitors, but are also suitable for battery-fed portablerecorders and radios.

Missing Current Limiter (MCL)A MCL protection circuit is built-in. The MCL circuit isactivated when the difference in current between theoutput terminal of each amplifier exceeds 100 mA (typical300 mA). This level of 100 mA allows for headphoneapplications (single-ended).

FUNCTIONAL DESCRIPTIONThe TDA7057AQ is a stereo output amplifiers with twoDC volume control stages. The device is designed for TVand monitors, but also suitable for battery-fed portable re-corders and radios.In conventional DC volume control circuits the control orinput stage is AC coupled to the output stage via externalcapacitors to keep the offset voltage low.In the TDA7057AQ the two DC volume control stages areintegrated into the input stages so that no coupling capa-citors are required and a low offset voltage is still mainta-ined. 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 twi-ce the signal frequency.Consequently, a reduced power supply with smaller capa

citors can be used which
