� Record and playback operation
Insert the low reflection disc, and after verifying the audio output in the normal mode playback set the record/playback TEST mode Recording from start address cannot be performed. Yes No Check whether the disc is record-prohibited.
Is RF waveform output to the pin 1 IC1201 or TP1274 when playback is performed after recording? No Does the level of pins 3 and 26,39 of IC1401 and the pins 9 and 19 of CNS1101 in record state differ from that in playback state? Yes Does RF pattern appear on the pin 50 of IC1201? Yes Check the IC1251, Q1251 to 1254 and CNS1252.
Yes
Check periphery of IC1401 and CNS1101. No
Check for IC1201 soldering failure. No
Is input waveform given to the pins 18 and 20 of CNS1902 in AUX input record in the NORMAl mode? No Is input waveform given to the pins 3 to 5 of IC1701?
Check the system PWB. No
Check connection between IC1701 and CNS1902. No
Yes Check the periphery of IC1701, check the pins 70, 71, 72, and 73 of IC1201.
� Focus servo failure
Is waveform on the pins 27 and 28 of IC1101 normal in the TEST mode focus gain coarse adjustment step? Yes Is level of pin 81 of IC1201 changed from H to L? Is pulse waveform output to the pin 82 of IC1201? Yes Does the pulse waveform duty of pins 18 and 19 of IC1201 change? Does waveform of pin 7 of IC1602 change? Yes Does waveform change on the pins 12 to 15 of IC1601? Yes Does waveform change on the pins 2 and 4 of CNS1101? Yes OK Check CNS1101 and pickup. Check soldering joint and part of IC1601. Check soldering joint and part of IC1201. Check waveform on the pins 8 and 9 of IC1201 and soldering joint. No Check waveform on the pins 9 and 10 of IC1101 and soldering joint.
