SAFETY PREAUTIONS 1.1 GENERAL GUIDELINES 1. When servicing, observe the original lead dress. if a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. 2. After servicing, see to it that all the protective devices such as insulation barrier, insulation papers shields are properly installed. 3. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards. 2.PREVENTION OF ELECTRO STATIC DISCHARGE(ESD)TO ELECTROSTATICALLY SENSITIVE(ES)DEVICES Some semiconductor(solid state)devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive(ES)Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor chip components. The following techniques should be used to help reduce the incidence of component damage caused by electro static discharge(ESD). 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your body by touching a known earth ground. Alternatively, obtain and wear a commercially availabel discharging ESD wrist strap, which should be removed for potential shock reasons prior to applying power to the unit under test. 2. After removing an electrical assembly equipped with ES devices,place the assembly on a conductive surface such as alminum foil, to prevent electrostatic charge buildup or exposure of the assembly. 3. Use only a grounded-tip soldering iron to solder or unsolder ES devices. 4. Use only an anti-static solder removal device. Some solder removal devices not classified as anti-static (ESD protected)can generate electrical charge sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, alminum foil or comparable conductive material). 7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the chassis or circuit assembly into which the device will be installed. Caution Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity(ESD). notice (1885x323x2 tiff) 1 3.Control Button Locations and Explanations Front Panel Illustration 6 2 3 4 7 8 9 5 10 11 12 13 14 POWER switch 6 Disc tray 11 STOP/BAND button 2 MIC 1 jack 7 Remote control signal sensor 12 FUNCTION button 3 MIC 2 jack 8 OPEN/CLOSE button 13 4 MIC VOLUME 1 knob 9 VFD display window DVD MODE PREV button TUNER MODE<< TUNING button 5 MIC VOLUME 2 knob 10 PLAY/PAUSE button 14 DVD MODE: NEXT button TUNER MODE: TUNING >> button 2 4.PREVENTION OF STATIC ELECTRICITY DISCHARGE The laser diode in the traverse unit (optical pickup)may brake down due to static electricity of clothes or human body. Use due caution to electrostatic breakdown when servicing and handling the laser diode. 4.1.Grounding for electrostatic breakdown prevention Some devices such as the DVD player use the optical pickup(laser diode)and the optical pickup will be damaged by static electricity in the working environment.Proceed servicing works under the working environment where grounding works is completed. 4.1.1. Worktable grounding 1. Put a conductive material(sheet)or iron sheet on the area where the optical pickup is placed,and ground the sheet. 4.1.2.Human body grounding 1 Use the anti-static wrist strap to discharge the static electricity from your body. safety_3 (1577x409x2 tiff) 4.1.3.Handling of optical pickup 1. To keep the good quality of the optical pickup maintenance parts during transportation and before installation, the both ends of the laser diode are short-circuited.After replacing the parts with new ones, remove the short circuit according to the correct procedure. (See this Technical Guide). 2. Do not use a tester to check the laser diode for the optical pickup .Failure to do so willdamage the laser diode due to the power supply in the tester. 4.2. Handling precautions for Traverse Unit (Optical Pickup) 1. Do not give a considerable shock to the traverse unit(optical pickup)as it has an extremely high-precise structure. 2. When replacing the optical pickup, install the flexible cable and cut is short land with a nipper. See the optical pickup replacement procedure in this Technical Guide. Before replacing the traverse unit, remove the short pin for preventingstatic electricity and install a new unit.Connect the connector as short times as possible. 3. The flexible cable may be cut off if an excessive force is applied to it.Use caution when handling the cable. 4. The half-fixed resistor for laser power adjustment cannot be adjusted. Do not turn the resistor. 3 5.

This servo DSP is capable of performing complex operations an d also provides a friendly interface for the system controller. By issuing type 1 and type 2 commands from the system controller, the servo DSP can accomplish various complicated servo control functions, such as tracking, seeking and MT1336/MT1376 chip register programming. As for the servo I/O circuits, it provides interface between the input servo signals and the Servo DSP. It has built-in ADCs to digitize the servo control signal and DACs to provide signals for the actuator and sledge motor. It also has a serial interface to communicate with the MT1336/MT1376 chip. Analog Front End The analog front end contains a data slicer circuit and a data PLL circuit. The RF analog signal from MT1336/MT1376 is quantized by the data slicer to form the EFM/EFM+ bit st ream, from which the channel bit clock is extracted by the data PLL.The EFM/EFM+bit stream and bit clock are then output to DPU for channel bit processing. DPU Data path unit (DPU) provides protection on data with lost synchronization patterns and demodulates EFM/EFM+ bit stream into the channel raw data that will be corrected by the decoder. The synchronization protection makes data after the synchronization pattern to be extracted even if the synchronization pattern is not found. Spindle Controller The spindle controller is used to control disc spindle motor. It includes a varipitch CLV clock generator, a CLV/CAV controller, and a PWM generator. The varipitch CLV clock enerator generates a reference colck for the speed of operation. The CLV/CAV 31 MT1379 PRELIMINARY, SUBJECT TO CHANGE WITHOUT NOTICE MTK CONFIDENTIAL, NO DISCLOSURE controller changes the mode and speed of operation according to servo register setting. The PWM generator generates pulse -width-modulated signal to drive disc spindle motor driver. CSS/CPPM The CSS/CPPM module provides functions necessary for decoding discs conforming to CSS/CPPM specification. System Parser The system parser is used to help the system controller to decode DVD/SVCD/VCD bitstream just after the channel decoder performing error correction. Acting as a DMA master, it moves bitstream data from RSPC buffer to video, audio, or sub-picture buffer according to system controller request. It also decrypts the scramble data of the CSS/CPPM sectors. Another function of system parser is providing system controller/DSP a DRAM memory copy controller to enhance system controller/DSP performance. Video Decoder The primary function of MT1379 is to support MPEG1 and MPEG2 video decoding. The video decode engine comprises of variable length decoder (VLD), inverse transformer (IT), motion compensator (MC), and block reconst ructor (BR). The video decode engine decodes the variable length encoded symbols in MPEG bitstream and performs inverse scan, inverse quantization, mismatch control and inverse discrete cosine transform onto the variable length decoded data. The motion compensator fetches prediction data from reference picture buffer according to motion vectors and motion prediciton mode for P and B pictures. Finally, the block reconstructor combines both the results of inverse transformer and motion compensator to derive the reconstructed image macroblock and write back to picture buffer. The video decode engine can also support JPEG and BMP file decoding by common image compression hardware kernels. Video Output The Video Output unit contains Video Processor, SPU, OSD, Cursor, TV encoder units, it performs § Reading decoded video from DRAM buffer § Scaling the image § Gamma/Brightness/Hue/Saturation adjustment and edge enhancement § Reading and decoding SPU and OSD data from DRAM buffer § Generating hardware cursor image § Merging the video data, SPU, OSD and cursor Video Processor The Video Processor unit controls the transfer of video data stored in the DRAM to an internal or external TV encoder. It uses FIFOs to buffer outgoing luminance and chrominance data, and performs YUV420 to YUV422 conversion and arbitrary vertical/horizontal decimation/interpolation, from 1/4x to 256x. With this arbitrary ratio scaling capability, the Video Processor can perform arbitrary image conversion, such as PAL to NTSC, NTSC to PAL, MPEG1 to MPEG2, Letterbox, Pan-Scan conversion or zoom in, zoom out. It is also capible of interlace to progressive conversion. The Video Processor unit performs the following functions: § Requests and receives the decoded picture data from the picture buffer in external DRAM for display § Resample vertical data to create 4:2:2 sample format § Optionally performs vertical/horizontal resampling of both luminance and chrominance data § Performs optional Gamma correction, luminance/chrominance adjustment, and edge enhancement The V ideo Processor unit contains two 2-tap vertical filters for luminance and chrominance . These filters are used to interpolate and reposition luminance and chrominance line to improve picture quality. These filters are capble of generating up to eight, unique subline value between two consecutive scan lines. The generation of lines depends on the ratio between the height of the source image and the target image. In applications where DRAM bandwidth are critical the filters can be configured as simple line-repeating to reduce the DRAM bandwidth required. The Video Processor unit integrates two separate horizontal postprocessing filter, a simple 2-tap linear horizontal filter and an 8-tap programmable filter. These filters are provided for scaling images horizontally along the scan line. These two filters is capable of generating up to eight, unique subpixel values between two consecutive pixels on a scan line. The generation of pixels depends on the ratio between the width of the source image and the target image. SPU 32 MT1379 PRELIMINARY, SUBJECT TO CHANGE WITHOUT NOTICE MTK CONFIDENTIAL, NO DISCLOSURE This is a hardware sub-picture decoder. It decodes the compressed SPU image bitstream and CHG_COLCON commands according to SPU header information previously decoded by system controller. The SPU module also allows two SPU objects to be displayed at the same time. SPU image is blended with main video stream. OSD The OSD module can operate with 2/4/16/256 -color bitmap format (1/2/4/8 bits), and 16/256 color RLC format, all have 16 levels of transparency. In addition, it accepts an special WARP mode, which inserts one programmable RLC code in the bitmap to reduce the image size stored in DRAM. It also features automatic shadow/outline generation in 2-color mode, 2 Hilight areas, 1 ChangeColor area and 1 OSDVoid area. One OSD area can occupy the full or a partial screen, or multiple OSDs can occur in a screen at the same time, only if they don't occupy the same horizontal line. The output image is blended with the video-SPU mixed stream. Cursor A hardware cursor generator is integrated in Video Ou tput Unit. The cursor image is a 32x32 4-color bitmap image, each colors are programmable. Cursor can be enlarged by 2 in both vertical and horizontal directions. Cursor image is multiplexed with video-SPU-OSD mixed stream. Audio Interface Audio interface consists of Audio Output Interface and Microphone Input Interface. Audio Output Interface The MT1379 can support up to 8 channel audio outputs. The output formats can be 16, 24, or 32-bit frames. Left alignment, 2 right alignment, or I S formats are all supported. With built-in PLL, MT1379 can provide the audio clock (ACLK) for external audio DAC at 384Fs, where Fs is usually 32KHz, 44.1KHz, 48KHz, 96KHz, or 192KHz. ACLK can also be programmed to be from outside MT1379. When ACLK is input to MT1379, the frequency could be 128*n Fs, where n is from 1 to 7. Audio raw (encoded) data or cooked (decoded) data can be output on a single line using S/PDIF interface. The output slew rate and driving force of this pad are programmable. Microphone Input Interface The MT1379 provides a microphone input interface. Two independent microphones’ data could be input to the MT1379. There are two independent digital volume control for these two input channels. The input data formats can also be left 2 alignment, right alignment, or I S formats. System Controller MT1379 uses an embedded Turbo-8032 as System Controller and provide ICE interface to increase the feasibility of F/W development. Also, MT1379 includes an build-in internal 373 to latch lower byte address from 8032 Port 0 and provide a glue-logic free solution. MT1379 supports up to 1M X 16 bits Flash ROM to store 8032 code, H/W related data, User data, etc. F/W upgrade can be achieved either by debug interface or by disk. 33 MT1379 PRELIMINARY, SUBJECT TO CHANGE WITHOUT NOTICE MTK CONFIDENTIAL, NO DISCLOSURE E LECTRICAL C HARACTERISTICS Absolute Maximum Rating Symbol Parameters Value Unit VDD3 VDD2 VDDA VIN VOUT Ta 3.3V Supply voltage 2.5V Supply voltage Analog Supply voltage Input Voltage Output Voltage Ambient Temperature -0.3 to 3.6 -0.3 to 3.0 -0.3 to 3.6 -0.3 to 5.5 -0.3 to VDD3+0.3 0 to 70 V V V V V °C DC Charateristics Symbol Parameters Min Typ Max Unit VIH VIL VOH VOL IIH IIL PD PDown Input voltage high Input voltage low Output voltage high Output voltage low High level input current Low level input current Power dissapation Power down mode 2.4 3.0 - - 3.6 0.8 VDD3 0.5 10 V V V V uA uA W W -10 1.0 0.1 34 8.3 Am29LV160D 16 Megabit (2 M x 8-Bit/1 M x 16-Bit) CMOS 3.0 Volt-only Boot Sector Flash Memory DISTINCTIVE CHARACTERISTICS ■ Single power supply operation ■ Embedded Algorithms — Full voltage range: 2.7 to 3.6 volt read and write operations for battery-powered applications — Regulated voltage range: 3.0 to 3.6 volt read and write operations and for compatibility with high performance 3.3 volt microprocessors ■ Manufactured on 0.23 µm process technology — Fully compatible with 0.32 µm Am29LV160B device — Embedded Erase algorithm automatically preprograms and erases the entire chip or any combination of designated sectors — Embedded Program algorithm automatically writes and verifies data at specified addresses ■ Minimum 1,000,000 write cycle guarantee per sector ■ 20-year data retention at 125°C ■ High performance — Reliable operation for the life of the system — Access times as fast as 70 ns ■ Ultra low power consumption (typical values at 5 MHz) ■ Package option — 48-ball FBGA — 200 nA Automatic Sleep mode current — 48-pin TSOP — 200 nA standby mode current — 44-pin SO ■ CFI (Common Flash Interface) compliant — 9 mA read current — 20 mA program/erase current ■ Flexible sector architecture — One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and thirty-one 64 Kbyte sectors (byte mode) — Provides device-specific information to the system, allowing host software to easily reconfigure for different Flash devices ■ Compatibility with JEDEC standards — One 8 Kword, two 4 Kword, one 16 Kword, and thirty-one 32 Kword sectors (word mode) — Pinout and software compatible with singlepower supply Flash — Supports full chip erase — Superior inadvertent write protection ■ Data# Polling and toggle bits — Sector Protection features: A hardware method of locking a sector to prevent any program or erase operations within that sector Sectors can be locked in-system or via programming equipment — Provides a software method of detecting program or erase operation completion ■ Ready/Busy# pin (RY/BY#) Temporary Sector Unprotect feature allows code changes in previously locked sectors ■ Unlock Bypass Program Command — Provides a hardware method of detecting program or erase cycle completion (not available on 44-pin SO) ■ Erase Suspend/Erase Resume — Reduces overall programming time when issuing multiple program command sequences ■ Top or bottom boot block configurations available — Suspends an erase operation to read data from, or program data to, a sector that is not being erased, then resumes the erase operation ■ Hardware reset pin (RESET#) — Hardware method to reset the device to reading array data This Data Sheet states AMD’s current technical specifications regarding the Product described herein.

HY57V641620HG is organized as 4banks of 1,048,576x16. HY57V641620HG is offering fully synchronous operation referenced to a positive edge of the clock. All inputs and outputs are synchronized with the rising edge of the clock input. The data paths are internally pipelined to achieve very high bandwidth. All input and output voltage levels are compatible with LVTTL. Programmable options include the length of pipeline (Read latency of 2 or 3), the number of consecutive read or write cycles initiated by a single control command (Burst length of 1,2,4,8 or Full page), and the burst count sequence(sequential or interleave). A burst of read or write cycles in progress can be terminated by a burst terminate command or can be interrupted and replaced by a new burst read or write command on any cycle. (This pipelined design is not restricted by a `2N` rule.) FEATURES • Single 3.3±0.3V power supply Note) • Auto refresh and self refresh • All device pins are compatible with LVTTL interface • 4096 refresh cycles / 64ms • JEDEC standard 400mil 54pin TSOP-II with 0.8mm of pin pitch • Programmable Burst Length and Burst Type • All inputs and outputs referenced to positive edge of system clock - 1, 2, 4, 8 or Full page for Sequential Burst • Data mask function by UDQM or LDQM • Internal four banks operation - 1, 2, 4 or 8 for Interleave Burst • . 40 Programmable CAS Latency ; 2, 3 Clocks HY57V641620HG PIN CONFIGURATION VDD DQ0 VDDQ DQ1 DQ2 VSSQ DQ3 DQ4 VDDQ DQ5 DQ6 VSSQ DQ7 VDD LDQM /WE /CAS /RAS /CS BA0 BA1 A10/AP A0 A1 A2 A3 VDD 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 54pin TSOP II 400mil x 875mil 0.8mm pin pitch VSS DQ15 VSSQ DQ14 DQ13 VDDQ DQ12 DQ11 VSSQ DQ10 DQ9 VDDQ DQ8 VSS NC UDQM CLK CKE NC A11 A9 A8 A7 A6 A5 A4 VSS PIN DESCRIPTION PIN PIN NAME DESCRIPTION CLK Clock The system clock input.

The product features good sound effect in appropriate space, and it has the following features: 1) 2.1/5.1 sound channel output; 2) Built-in five sound channel power amplification, and adaptable to AC-3/DTS and stereo music replay; 3) Six sound channel volume control and independent level control, with tone adjustment function. 二、Principle block diagram Signal input Electronic volume and tone adjustment CPU system control Power amplific ation Output Remote Receiving and display part 三、 System composition The device comprises input board, output board, power amplification board and control panel. The input board and output board only consist of a few terminals. The power amplification board is the most important part, fulfilling control, amplification and power supply for the whole system. In the following is the brief description of the principles for the power amplification board. 1、 Power supply part In consideration of the big output power of the subwoofer, the device employs a ring transformer for power supply. A group of 18V(AC) voltages is output from the transformer, which will be subject to rectification and filtering and will output +22 V voltage to power IC TDA8947 and IC TFA9843 for power supply. One line of output 22V voltage goes through the current limiting resistor R101, voltage regulating diode VD104 and capacitor C108 and then output +9V voltage to IC 75347; the other line goes through R100 and voltage regulating diode VD105 and then output 5V voltage power supply for the CPU and the control panel. 2. Signal input, volume adjustment The device has six channels for signal input. The signals input through each channel will go through the filtering capacitor before being directly delivered to the IC TDA7448 for volume adjustment. In addition, one line of signals will be derived from the L and R main sound channels and overlapped on the SW input. As a result, 2.1 output result will be achieved even when there are only L and R sound channel inputs. IC TDA7448 is an IC with six-channel independent volume adjustment. With its gains adjustable from 0 to 79 single DB, it is applicable to home theater products. With benefits such as small range of power supply, low power consumption and wide temperature scope, it is a quite competent IC, and the functions of its main pins are listed in the following table: Pin name Pin Numbering Function description IN1 2 Signal input IN2 19 Signal input IN3 3 Signal input IN4 18 Signal input IN5 4 Signal input IN6 17 Signal input OUT1 7 Signal output OUT2 14 Signal output OUT3 6 Signal output OUT4 15 Signal output OUT5 5 Signal output OUT6 16 Signal output GND 11 Grounding pin CREF 20 Reference voltage VS 1 Power voltage SCL 10 Clock control line SDA 9 Data control line ADDR 12 Digital voltage The IC principle diagram is illustrated in the following figure: 2、 Amplifying circuit part Principle: as far as the signals output from the IC 7448 are concerned, the signals of the main sound channel will be delivered to the N101 IC TFA9843 for power amplification; the central surround signals will be filtered and delivered to the N106 IC TDA8947 for amplification; the subwoofer signals will first pass experience amplitude limit (the amplitude limit circuit comprises VD110 and VD113 diodes) and pretreatment before being delivered to the N102 IC TFA9843. Amplitude limit is aimed at preventing excessive size of signals, which may, after amplification, damage the loudspeaker due to excessive power. Because the power supply of the amplification IC is fulfilled by a single power source, all amplified and output signals will have DC, therefore, the signals will still experience filtering before being output to the loudspeaker. IC TFA9843J is used for dual sound channel power amplification. With standby and mute modes, free from switch impact, and with functions such as short circuit protection and overheat protection, it can effectively be prevented from being damaged in case of IC abnormality. In ordinary output mode, the IC can supply for each channel a maximum of 20W power output. When BTL output is employed, the power can be as high as 40W. In addition, the IC features powerful anti-ripple performance, with little power consumption in the standby state. The functions of the various pins of the IC TFA9843J are listed in the following table: Symbol Pin Function IN2+ 1 2nd channel input OUT2- 2 2nd channel output CIV 3 Common mode input voltage suppression 1N1+ 4 1st channel input GND 5 Ground SVR 6 Reference voltage MODE 7 Mode selection OUT1+ 8 1st channel output VCC 9 Power supply IC TDA8947J is used for four channel power amplification. Its features are similar to those of the IC TFA9843J, however, its output power is bigger, and a single sound channel can be as high as 25 W. 3、 Control circuit The device employs IC AT89C2051 to serve as its core part to control the operation of the whole device. With low voltage and high performance, it employs 8-bit 2K bytes flash and ROM single-chip. Boasting 15 I/O ports and six interrupt sources; it has features such as low power consumption and standby mode. The principle block diagram of the IC is illustrated in the following figure: Reset circuit: The device employs high level for resetting. By making use of the feature of the capacitor C109 that there is no jump for of voltage, the device ensures that there is no jump of capacitor voltage at the instant of power on. The base electrode of the triode V100 has low level, so that the triode is not on, and the 5V voltage is added to the first pin of the CMP through resistor R114. With capacitor charging, the positive voltage of the capacitor gradually climbs; when the voltage attains a certain limit, the voltage regulating diode is reversely on, so that the base electrode of the triode has high level, the triode is on, the reset pin voltage turns into low level, thus fulfilling resetting. The circuit diagram is illustrated in the following figure: Reset circuit Mainly remote control is employed for adjustment of the status of the device. The signals received by the remote controller are delivered to the sixth pin of the CPU. After the signals are processed inside the CPU, pins 8 and 9 deliver control signals to adjust the volume of the device. Then there will be corresponding display on the control panel through P1 port, so that users are able to understand the status of the device. In addition, pins 2 and 3 of the CPU are used to control the mute state of the main sound channel and the central surround. 5. Control panel The control panel of the device consists of a remote control receiver and a nixie tube. Because the device is operated through remote control, the remote control receiver is the sole path for man-machine communication. The nixie tube is used to display the ongoing operation and the state of the whole system. 6. Power on/off mute and mute circuit Power on/off mute: as shown in the figure, at the instant of power on, the voltages on both sides of capacitor C169 won’t experience jump-off, as a result, the low level will remain unchanged, the triode V106 is off, V105 is on, MUTE1 output turns into low level, LRM and SCM signal levels turn lower, and then there is mute. When the capacitor is charged to turn on VD109 5.1V voltage regulator tube and V104 9014 triode, the level of the V105 base electrode will become lower, so that triode V105 turns off, MUTE1 outputs high level, and the mute then comes to an end. The same case applies to power off. Capacitor C169 experiences fast discharge through diode VD112, so that the positive voltage experiences fast decrease, triode V106 turns off, V105 turns on, MUTE outputs low level and turns on. It is through this circuit that we achieve no impact sound when power is on/off. Mute circuit: the mute function is realized through the mute signals transmitted by the CPU. Press the MUTE key on the remote controller, the remote control receiver will receive signals and transmitted them to the CPU for processing. Then, pins 2 and 3 of the CPU will transmit high level, so that triodes V107 and V108 turn on, LRM and SCM levels become lower, and the mute is on. It makes use of the mode selection feature of the IC TDA9843 and IC TDA8947. For more details, please refer to the information for the IC TDA9843. 四、 Troubleshooting The electronic circuit inside the device is relatively simple, without too many complicated control and detection circuits. As a result, signal injection method is employed for the maintenance of the device, namely, signals are added to the input end, and flow along the signal procedure. If signals are interrupted at a certain place, then we can determine that the fault may happen here. The maintenance of the device is in compliance with the following procedures: 1、 Check whether the power supply part is normal, namely, check whether the power supply of 22V, 9V and 5V is normal; 2、 In case of abnormal sound but normal power supply, check whether the mute level is normal, and then consider whether it is attributed to the wrongness of other parts; 3、 For a device with abnormal display, first determine whether there is anything wrong with the nixie tube, and then check whether there is anything wrong with the CPU. ******************ATTACHMENT*************************** 1: Block diagram 2: Electronic diagram 3: PCB silk screen 4: IC specifications OUTPUT BOARD MAIN BOARD L R R 5.1CH INPUT VOL C SL SR L R C¡¢SR¡¢SL CONTROL CONNECTED BLOCK SL POWER AMP SW SL Coupling Capacitor POWER AMP L SW R L¡¢R INPUT BOARD C L SR C LPF SR AMP SW ground POWER AMP CPU MUTE CONTROL SW BTL LED REMOTE RECEIVER PANEL BOARD POWER connected DISPLAY SUPPLY +5V R100 270/3W VD100 XS100 2 1 CON2 1N5404 +22V +9V R101 620/1W VD101 1N5404 C100 VD102 1N5404 4700u/35V FL100 T6.3AL 250V +5V 18K 104/100V VD104 C102 C103 VD105 C108 9.1V 220u 473 5.1V VD116 3.3V C104 T2AL 250V C126 103 1 2 R104 22K R122 4.7K C109 4.7K 22K R110 22K R124 4.7K R109 22K R126 4.7K R113 22K R165 47K 2 3 18 10u/16V C116 4 10u/16V C117 OUT2 IN3 OUT3 IN4 OUT4 IN6 11 20 10u/16V C118 OUT1 TDA7448 1 MUTE1 OUT6 SCL CREF SDA ADDR R127 10u/16V +9V R151 100K C127 N105A 3 100K +9V P_LRM R171 L P1.7 (TXD)P3.1 P1.6 XTAL2 P1.5 XTAL1 P1.4 (INT0)P3.2 P1.3 (INT1)P3.3 P1.2 6 SL 15 SR R134 R133 R135 R136 19 18 17 (T1)P3.5 P1.0(AIN0) 15R117 4.7K 14 R119 4.7K 13R118 4.7K 12 R120 4.7K R173 LRM 1K 100u/25V C146 0.1u C132 R176 P_SCM C134 1K R166 100K 9 0.1u C139 472 C135 0.1u 1K 1u/16V 150K 22K C152 1 2 3 4 5 6 7 8 9 SR 22u OUT+ OUT4+ GND1 VCC2 VCC1 GND2 OUT2OUT3MODE2 CIV IN2+ IN4+ SGND SVR IN1+ MODE1 IN3+ 0.1u 6 100K 5 N105B IC4558 C136 1u 7 LRM R144 1K R172 100K VD108 1N4148 V109 2N5401 0 R143 V110 R146 10K S8050 100K C137 0.47u C145 C163 22u/16V 100u/25V 473 C147 100u/35V TFA9843J OUT/SL +22V 17 OUT/C 16 15 14 13 12 11 10 VD107 C106 473 100u/35V C148 C174 C144 1u/16V 100u/25V 1N4148 TDA8947J C C149 +22V 9 8 7 6 5 4 3 2 1 47u/35V OUT/R N102 VCC OUT1+ MODE SVR GND IN1+ CIV OUT2IN2+ TFA9843J C160 104 R158 C107 473 R155 C105 VCC OUT1+ MODE SVR GND IN1+ CIV OUT2IN2+ OUT/SR C140 472 1K +22V N106 10K GND N101 R174 9014 C173 R145 R112 100K 182 C150 C142 472 MUTE1 1N4148 VD115 SL R148 100K R152 100K R 104 R111 C120 R156 C143 C133 10u/16V R177 4.7K 9 8 7 6 5 4 3 2 1 OUT/L C170 472 R139 10u/16V C121 OUT/R 22u/25V L 0.1u P_SCAN 10K VD106 1N4148 C129 +5V RE CON12 9015 V108 10 V104 9015 1K R147 100K SW V103 9015 R175 10u/16V C115 C V102 9015 11 GND AT89C2051P3.7 1 2 3 4 5 6 7 8 9 10 11 12 330 330 330 330 V101 16 C138 472 10u/16V C119 12 XS105 20 (T0)P3.4 P1.1(AIN1) R142 R168 100K 10 VD114 MUTE1 1N4148 R141 C114 R 16 (RXD)P3.0 V107 9014 C131 104 10u/16V 14 5 Vcc C113 100 C130 10U/16V Vr 4.7K RST/Vpp Vr IC4558 100K C166 22K 1 C165 R164 R116 223 2 R163 103 +5V 4.7K R131 7 10u/16V C151 4 47K R115 4.7K R1531N4148 1N4148 47K C167 103 R154 6 7 P_LRM VD113 VD110 47u/16V C122 10u/16V 10u/16V 4.7u/50V OUT5 GND VS 4M 10 100 IN2 5 8 9014C IN1 IN5 17 G100 C172 N103 19 30P 30P R130 C164 C123 9 C110 10u/16V C112 4.7K R149 100K CON7 R123 103 4 4.7u/50V 1u/16V 10u/16V C111 22K R108 R125 CON2 R150 100K R105 XS106 L 7 R 6 SL 5 GND 4 SR 3 C 2 SW 1 4.7K S8050 V106 C169 CON2 XS103 CON2 R121 R167 10K R140 VD109 5.1V 8 2 1 R138 47K XS102 1 2 C124 C125 270 V105 FL101 XS101 22K R106 2.7K/0.25W C168 3 V100 9014 473 R102 22K 100u R132 N100 2 +22V 1N4148 R107 22u/50V 1 R114 4.7K R103 +5V P_SCM C101 VD112 1N4004 P_LRM 10K R170 10K R169 VD103 1N5404 VD111 R128 4.7K 10K R129 OUT/L R157 1/1W OUT/SL C128 104 OUT/SR XS104 1 2 CON2 OUT/C C153 220u/25V C154 220u/25V C155 220u/25V C156 220u/25V C157 220u/25V 1/0.5W R159 C158 104 1/0.5W R160 XS107 C159 104 1/0.5W R161 C161 104 1/0.5W R162 1/0.5W C162 104 1 2 3 4 5 6 7 CON7 R L SL SR C GND
