Fully functional usable service manual. Considering the age of the manual and device quality was better than expected
;
Thank you very much, I've been very happy to find this manual on "Owner Manual". It's a perfect copy and it has been really useful for my work!
;
It took about 24-hours after my payment before I was able to get to the download. Apparently, payment processing is not 100% automated. That is no big deal, just be aware of that going in.
After I got to it, it was in good shape, easy to read, etc. Not some cheap FAX copy looking thing.
Also, this site was the cheapest I found. Another Plus!
;
Good price, very legible manual, exactly what I needed -- but had to wait a day to actually get the download of the manual. Would have preferred to download it immediately after payment rather than waiting for someone to "process" my order. I was surprised that I had to wait that long.
;
As the only source for this manual it rather rank quite high since it is well scanned and perfectly readable.
SECTION 5 ELECTRICAL ADJUSTMENTS
Precautions for Adjustment 1. Before beginning adjustment, set the equipment to service mode. After the completion of adjustment, be sure to reset the service mode. For more information, see �Service Mode (service program) � on page 8. 2. Perform adjustments in the order given. 3. Use YEDS-18 disc (Part No.: 3-702-101-01) unless otherwise indicated. 4. Power supply voltage requirement: DC2.5 V in battery terminal VOLUME knob : Minimum RESUME switch : OFF ESP switch : OFF AVLS switch : NORMAL HOLD switch : OFF Before Beginning Adjustment Set the equipment to service mode (See page 8) and check the following. If there is an error, repair the equipment. � Checking of the sled motor 1. Open the upper panel. 2. Press the + and = keys and check that the optical pickup can move smoothly without sluggishness or abnormal noise in innermost periphery n outermost periphery n innermost periphery + :The optical pick-up moves outwardly. = :The optical pick-up moves inwardly. � Checking of focus searching 1. Open the upper panel. 2. Press the ^ key. (Focus searching operation is activated continuously.) 3. Check the object lens of the optical pick-up for smooth up/ down motion without sluggishness or abnormal noise. 4. Press the p key. Check that focus searching operation is deactivated. If not, again press the p key slightly longer. VCC Adjustment Adjustment Procedure:
digital voltmeter (DC range) MAIN board TP401 (VCC) (See page 11) + �
Focus bias Check Condition: � Hold the set in horizontal state. Check Procedure:
oscilloscope (AC range) MAIN board TP522 (RFO) TP520 (VC) (See page 11) 2k�

1. Set the equipment to service mode stop state. (See page 8.) 2. Connect the oscilloscope to the test point TP522 (RFO) of the MAIN board. 3. Move the optical pick-up to the center by pressing the + and = keys. 4. Put the disc (YEDS-18). 5. Press the ^ key. From focus searching, focus is turned ON while entering CLV drawing-in mode. Tracking and sled are turned OFF. 6. Press the PLAY MODE key. (Both tracking and sled are turned ON.) 7. Check the oscilloscope waveform is as shown below. A good eye pattern means that the diamond shape (�) in the center of the waveform can be clearly distinguished. RF SIGNAL REFERENCE WAVEFORM (EYE PATTERN)
VOLT/DIV : 200 mV (With the 10:1 probe in use) TIME/DIV : 500 ns
RF level 1.0 ± 0.2V
To watch the eye pattern, set the oscilloscope to AC range and increase the vertical sensitivity of the oscilloscope for easy watching.
8. Stop revolving of the disc motor by pressing the p key. 9. After the completion of adjustment, reset service mode. (See page 8.) Check Location: MAIN Board (See page 11.)
1. Set the equipment to service mode stop state. (See page 8.) 2. Connect the digital voltmeter to TP401 (VCC) of the MAIN board. 3. Adjust RV401 on the MAIN board so that the reading on digital voltmeter goes 2.75± 0.05 V. 4. After the completion of adjustment, reset service mode. (See page 8.) Adjustment Location: MAIN board (See page 11)
