I found this manual to be complete in every detail. Besides the schematic it has a complete set of alignment instructions which are easy to understand. It also includes a complete parts list as well as an explanation of how the power supply and safety shutdown circuits operate. Even a schematic of the tuner is included.
The product was good and just what I needed, however I had moderate difficulty with the down load because the sight would not recognize my pass word. I was finally given a direct link to the manual and that worked.
Very quick and easy website to use and fast download of manual, quality of manual is excellent and will be pleased to use this service again in the future, thanks so much!
It is an very good and clear scanned service manual.
Easy to order the manual. Good quality and fast delivery.
CDP-S3 SECTION 5 ELECTRICAL ADJUSTMENTS
E-F Balance (1 Track jump) Check
oscilloscope BD board TP(TEO) TP(DVC)
1. CD Block is basically designed to operate without adjustment. Therefore, check each item in order given. 2. Use LUV-P01 (4-999-032-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10Mâ¦ impedance. 4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks. S-Curve Check
BD board TP(FEO) TP(DVC) Oscilloscope
Procedure : 1. Connect an oscilloscope to TP (TEO) and TP (DVC). 2. Turn Power switch on. 3. Load a disc (LUV-P01) and playback the number nine track. 4. Press the N button. (Becomes the 1 track jump mode.) 5. Confirm that the level B and A (DC voltage) on the oscilloscope waveform.
1 track jump waveform center of waveform B DVC level=1.0 Â±0.5Vp-p symmetry A (DC voltage)
Procedure : 1. Connect an oscilloscope to TP (FEO). 2. Connect between TP (FEI) and TP (DVC) ( 1.65 V) by lead wire. 3. Turn Power switch on. 4. Load a disc (LUV-P01) and actuate the focus search. (In consequence of open and close the disc tray, actuate the focus search) 5. Confirm that the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 2 Â± 0.5 Vp-p.
S-curve waveform symmetry
6. Adjust RV101 on the BD board so that the center of waveform becomes the same voltage of DVC. (i.e. A=0V) Adjustment Location: [BD BOARD] (Conductor Side)
A within 2 Â±0.5Vp-p B
6. After check, remove the lead wire connected in step 2.
Note : â¢ Try to measure several times to make sure than the ratio of A : B or B : A is more than 10 : 7. â¢ Take sweep time as long as possible and light up the brightness to obtain best waveform.
RF Level Check
BD board TP(RFDC) TP(RFAC) TP(DVC) oscilloscope
TP (DVC) TP (RFAC) 15 1 IC103 16 30 TP (FEO) TP (TEO) 40 41 TP (RFDC)
IC101 60 61
Procedure : 1. Connect an oscilloscope CH1 to TP (RFDC) and CH2 to TP (RFAC). 2. Turn Power switch on. 3. Load a disc (LUV-P01) and playback. 4. Confirm that oscilloscope waveform is clear and check if RF signal level is correct or not.
Note : Clear RF signal waveform means that the shape â â â can be clearly distinguished at the center of the waveform.
