 ;
fast delevery of the manual and very complete manual, now my Akai works again, will buy again, thanks.
 ;
Tartalma megfelelő. Szebb kivitelű is lehetne a scannelés.
;
I never been disappointed in my dealings with owners-manuals.com
;
Excellent printing quality. A complete and very useful manual with all details.
;
Even if the PDF is a scan, I can read the information I need.
The price is affordable and the service (mail sending) is very fast.
Thanks ! Regards. William (Fan of Kenwood)

� Test mode check
Insert a high reflection (low reflection) disc, and once perform automatic adjustment in AUTO mode, and then check in MANUAL mode. Simultaneously observe waveforms of EFM(TP145), FEOUT(TP143), and TEOUT(TP144). Does the optical pickup move to outer/inner periphery when the / button is pressed? Yes Is tracking error offset measurement within allowable range? Yes Is focus error offset measurement within allowable range? No Yes Is laser power normal when laser lights? No Yes Does focus access occur in focus gain rough adjustment step? Yes Is adjustment out of allowable range? No Yes Check whether values of pins 10, 11, 14, and 15 of IC201, pins 30 and 32 of (IC101) (TP143) change when the / button is pressed. Check the pins 21 and 22 of IC101, the pins 6 and 52 of IC401, the periphery of Q101, Q102, and Q103, CNS101, and pickup flexible PWB insertion. No Check the pins 56 and 57 of IC201, the pins 25, 27, 29 and 30 No of IC601, the pins 10 and 11 of CNS601, and the slide motor terminal. Check Vref values of pins 3 and 4 of IC101 and pin 22 of IC201.
Check Vref values of pins 3 and 4 of IC101 and pin 22 of IC201.
No
Check the pins 52 and 53 of IC201, the pins 10, 12, 14, and 15 of IC601,and the pins 5 and 7 of CNS101.
Does the disc motor rotate in the same step? Yes Is focus servo applied in tracking gain adjustment step? Yes Doesn't the disc motor rotate at high speed in the same step? No No No
Check as stated in item "The disc motor does not rotate".
Check timing of pins 91 and 92 of IC401 and TP144(TEOUT).
Check EFM waveform of pin 23 of IC201 in case of high reflection. Check ADIP waveform of pin 4 of IC201 in case of low reflection.
Yes Is tracking gain adjustment within allowable range in the same step? Yes Is adjustment within allowable range in tracking error balance adjustment step? Yes Is tracking servo applied in focus gain fine adjustment step? Yes Is slide servo applied in continuous playback step? Yes Is cluster address counted up continuously in the same step? No Yes Continued on the next page. � 39 � No No Check whether value of pin 20 of IC201 and TP144(TEOUT) changes or DC shift occurs when the / button is pressed. Check whether values of pins 16 to 19 of IC201 and TP144(TEOUT) change when the / button is pressed.
No
No
Check waveforms of pins 54 and 55 of IC201, pins 18, 19, 21, and 23 of IC601, pins 4 and 6 of CNS101.
Replace IC201.
Check waveforms of pins 53 to 56 of IC101 and pins 23 to 25 of IC201. (In case of low reflection check also the waveform of pin 4 of IC201.)
