Before final test unit was 4 days on burn-in-bench with music.2. Take the unit from burn-in-bench to Q.C and play it immediately. Keep the line 120V A.C.3. Check physically and check the components.-check all capacitor and devices direction. Capacitor stand up right way i.e. check co-solder.-check any missing parts.-check all fuse sockets.-check main board tight up with screw and washer.-check any screw missing.-check balance lock working smoothly.-check all output transistors position with pad.-check main transistors position with pad.-check main transformer tight very well.4. Adjust bias 26mV for every output devices for both channels. Wait 7 to 8 minutes after each adjustment. Also adjust offset to 0mV.5. Measure rail and pre-driver voltage.6. Measure A.C voltage for bridge.7. Measure supply voltage for relays. +15V and 15V for both channels. +12V and 12V.8. Measure reference voltage 8.1V on both channels.9. Measure reference voltage for protection 78V.10. After setting the bias, connect load and input signal. Check output signal. Check phase with input signal.11. Measure frequency response, slew rate, gain, signal to noise ratio.12. Check the output signal from 20Hz to 20KH with load in following combination. Also measure the output power.Regegur-stereoBalance-stereoRegegur-monoBalance-mono13. Check phone-jack.14. Check protection on both channels.15. Check noise with speaker.16. Put the jumpers and varistor for required A.C voltage.17. Plug unit again and check rail and pre-driver voltage.DIAGRAMSCD/DVD-1POWER SUPPLY - B2A1XR03 (1)Class - 16CD/DVD-1Class - 17POWER SUPPLY - B2A1XR03 (2)CD/DVD-1RIGHT OUTPUT - B2A2XR02 (2)Class - 18CD/DVD-1VIDEO OUTPUT - B2A6XR06Class - 19CD/DVD-1HDCD - B2A7XR04Class - 20CD/DVD-1DISPLAY - B1A5XR01Class - 21CD/DVD-1Block diagrams 29ASD-16.6.Block diagramsServoDISK MOTORSLEDGE MOTORTRAY MOTOR6 MHz8.46 MHzLM833DuP (8051 CORE)ADC7207SAA7399MACE2SERVOB_V4B_SYNCB_FLAGB_DATAB_BCLKB_WCLK6SAA7335HL/E/M2HD61DECODERHF-IN37304BA6856FPMOTOR-ICHALL-FEEDBACKDRIVEMOTO-INTACHO-OUTLOADERCDMOPUDVD-LASERCD-LASERRADIALFOCUSMHALLMHALLMEND-SWITCH4-WIRESFLEX 24PFLEX 11PFLEX 8PPCS-PRE-AMPLDRIVERS71047103424424+5GNDPCSPHI-INPUTREFBA5938FMSERVO OUTPUTSTRAY-SWITCHSLEDGERADIAL FOCUSTRAY1TRAY2522CONTROLLINES1104110613011100117311CONTROL BUSDATA/ADDRESS BUSAD0:7AD0:7A8:16A0:16A0:7AD0:7AD0:7PSENNFLASH ROMADRESS LATCH72027201MEMORY132KS-RAMDATAADDRESSCONTROL81514268_1362012Laser#1Laser#2DiodeAmplifiersProcessingDPDLand/GrooveSwapDual LaserSupplySerialI/FacePush Pull3 BeamTrackingVar GainServoSignalsDVDCDD1-D6MUXCALF_MACEO_CENTRALLandV & I referencesHeaderOffsetMutecompensationsMUXSILDSICLSIDA4646TO STi5505 ON DIAGRAM 5DVDALAS2+TZA1033RFoSTB_DALASASD1 BOARD SERVO PART73107102CY7C199-15CAM29F00274HCT573DBLOCKDIAGRAM DIGITAL PARTTXD_BERXT_BECFRSUR4TO/FROM STi5505 ON DIAGRAM 5S2BI2SHPSWEQUALIZER7110-71117100-7106-7101RSTNPOR132?CL06532065_036.eps180500 30ASD-16.Block diagramsDidital7504ST24E32M675057612-76187611SERVICERESETN-8Vstby76007503STi5505SERVICE4I/OOSDDECODERENCODERCONTROLLERI2CSDRAM CONTROLLERPROGRAMMABLEVIDEOAUDIOMPEG DECODERDEMULTIPLEXERMEMORY INTERFACEHOSTST20UARTUARTINTERFACEFRONT END16MbB_SYNCB_FLAGB_BCLKB_DATAB_WCLKB_V41501STB_CONTAM29LV160BT7401MK27427616SEL_ACLKCTS_SERRTS_SERRXD_SERTXD_SER4SURCFRRXD_BETXD_BES2B4I2S616021600TO/FROMDISPLAYBOARDA/V-MUXINTERFACESERIALSUPPLYPOWER STB_CONT+6Vstby+5Vstby+5V+3V3SYNTHESIZERFLASHCLOCK27 MHz1603MUTEMUTE_AVSCART0_6_12VDEEM0:1P506-5V+5VR/CGB/CVBSCVBS/YTO/FROMCONN.CONN.CONN.CONN.0/6/12VSERVICE+12Vstby7608,7609,76107604, 7607AUDIOVIDEOSUBPICTURE3V35VVIDEOFILTERBUFFER24SCART0:1MUTESCLKPCM_OUT0PCM_CLKLRCLKSPDIF_OUTR_OUTG_OUTB_OUTC_OUTCVBS_OUTY_OUT2431604CONN.BOARDA/V-MUXTO2OPTION+12Vstby+3V3+6Vstby-8VstbyHSYNCPCMout1PCMout2Y - CEEPROMDIG_OUTBCLKDATAACLKWCLKSDASCLK2222SDASCLKSCLKSDA7405SDRAM7404MT48LC1M16A1TG -7S16MbSDRAM16MbSDRAM INTERFACESYSTEM DATA BUSSYSTEM ADDRESS BUSSYSTEM CONTROL BUSCVBSRGBS-VHSDIG.
