XG-V10XUTROUBLE SHOOTING T ABLE (Continued)Checking the video unit circuitIs there video signal output at pin (7)of IC1405?YesIs there video signal input at IC4001?YesAre there signal outputs at pins (6)and (8) of IC4001?YesCheck the low-pass and buffer circuitsof Q6008 thru Q6014. Is the signal asspecified?YesNoNoNoNoCheck the IC1403, IC1406 selectorswitch, terminal voltage and inputcircuit.Check the low-pass and buffercircuits of Q4002, Q4003 and Q4004.Check IC4001 and its peripheralcircuits (bias).Check Q4005 thru Q4008 and theirperipheral circuits.Go to "Checking IC801 (RGB signaloutput circuit)".Checking IC801 (RGB signal output circuit)NoAre there RGB output waveforms atpins (31), (32) and (33) of IC803?NoGo to "No colour or unusual tone","No Y signal" or "Out of sync".YesAre there output waveforms at pin1 of Q6801, Q6802, Q6803?NoCheck the data transfer and otherperformance at pins (17) and (18) ofvideo IC803.YesCheck Q6801, Q6802, Q6803 andtheir peripheral circuits.Are there output waveforms at pin(8), (10), (12) of SC8404?NoYesCheck IC6801, Q6807, Q6808,Q6809 and their peripheral circuits.Go to "Trouble shooting table for PCI/F unit".42
XG-V10XUTROUBLE SHOOTING T ABLE (Continued)Checking the chroma and Y signals of IC801(RGB signal output)Are there signal inputs at pins (12),(31) and (37) of SC401?NoYesGo to "Checking the video unitcircuit".Are there output waveforms at pins(7) of IC6014 (chroma signal) and(7), (Y signal)of IC6015?NoYesAre there signal inputs at pins (20)(chroma signal) and (21) (Y signal)of IC803?NoCheck the IC6009 IC6010 and IC6011switching and their peripheral circuits.If there is no signal at pins (1) ofIC6014 and pin (5) of IC6015 and pin(16) of IC6010 check 3-D noisereduction circuit (IC6009).Check IC6009 (3-D noise reductioncircuit) and its peripheral circuits.YesGo to "Checking IC801 (RGB signaloutput circuit)".Check IC803 and its peripheralcircuits.Checking IC806 (3-D noise reduction circuit)and its peripheral circuitsAre there signal inputs at pins (40)(Y signal) and (45)(chroma signal) ofIC6009?YesAre there signal outputs at pins (55)(Y signal) and (51)(chroma signal) ofIC8001?YesAre there signal outputs at theemitters of Q6010 (Y signal) andQ6015 (chroma signal)?YesCheck IC6011, IC6014, IC6015 andIC801 (RGB signal output circuit).NoNoNoCheck the buffer circuit of Q6007 thruQ6011 as well as Q6013 thru Q6014.Check IC6008, IC6010 (memory) andtheir peripheral circuits.Check the low-pass circuit aroundQ6010, Q6012 and Q6015.No colour or unusual tone (NTSC, PAL, PALM, PALN)Is there chroma signal input at pin(20) of IC801?YesAre there signal outputs at pins(46)(R-Y) and (45)(B-Y) of IC801?YesCheck IC804, IC805 and theirperipheral circuits.NoNoGo back to the signal processingblock.Check the oscillation of X801, X802,X803 and X804 and their peripheralcircuits.43
