SECTION 4 SERVICE MODE
Key Check Mode for Complete Lighting of LED/Fluorescent Display Tube Perform this mode to analyze and check malfunctions such as display defects and when buttons do not work. Procedure: 1. Press the 1/u button to turn on the power. 2. Press the DISPLAY button and ^ button together. 3. All LEDs and the fluorescent display tube will light up completely. 4. Pressing the FUNCTION button here will light the fluorescent display tube in the following order; Partial lighting 1 n Partial lighting 2 n Complete lighting n Partial lighting 1 Turning the VOLUME dial will switch the lighting order of the LED. To end without shifting to the key check mode, press the 1/u button to end. 5. Pressing the p button sets the key check mode. 6. During the key check mode, KEY=0 JOG=0 will be displayed on the fluorescent display tube. Pressing a button will increase the value of KEY=. However the value will not increase for buttons which have already been pressed once. Rotating the VOLUME knob in the clockwise direction increases the value of JOG= in the order of 1, 2, 3. and rotating in the counterclockwise direction decreases in order of 10, 9, and 8. 7. To end the check mode, press all buttons (8 buttons). KEY-OK will be displayed. Then press any button, and disconnect the power cord from the outlet. Checking the Sub-Clock Perform this mode to check clock operations. Procedure: 1. Connect an oscilloscope and frequency counter between the pin (TP791) and ground of IC701 of the MAIN board. 2. Press the and 1/u buttons together to display 91P = 32.768k on the fluorescent display tube. 3. Check that the signal on the oscilloscope becomes a 32 kHz rectangular waveform and the reading of the frequency counter becomes 32.768 kHz. 4. Press the 1/u button to end. Sled Servo Mode In this mode, the CD sled motor can be operated freely. Execute it when cleaning the pick-up. Round holes can be seen on the topmost board when the case is opened. Move the pick-up and clean off the dirt in these round holes using a cotton swab. Procedure: 1. Press the DISPLAY and buttons with the power of the unit OFF. 2. When the sled servo is set, MANUAL is displayed on the fluorescent display tube. 3. Pressing the +/TUNING/) button when the CD is in the stop state moves the pick-up to the outer track. Pressing the =/ TUNING/0 button moves it to the inner track. 4. To end this mode, perform the following steps. 1) Move the If not, the disc cannot be removed. 2) Press the DISPLAY and buttons together. Note: When ending this mode, be sure to move the pick-up to the innermost circumference. If not, the disc cannot be removed. Do not move the sled motor more than required as this will damage the gears.

CD SECTION

Note: 1. CD Block is basically designed to operate without adjustment. Therefore, check each item in order given. 2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10M impedance. 4. Clean the object lens by an applicator with lens cleaning liquid when the signal level is low than specified value with the following checks. 5. Adjust the focus bias adjustment when optical block is replaced. Focus Bias Adjustment Perform this adjustment when the optical pick-up has been replaced or repaired.

Procedure : 1. Connect oscilloscope to test point TP (FEO). 2. Connect between test point TP (FOK) and Ground by lead wire. 3. Turn Power switch on. 4. Put disc (YEDS-18) in and turned Power switch on again and actuate the focus search. (actuate the focus search when disc table is moving in and out.) 5. Check the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 2.4 0.7 Vp-p. S-curve waveform

symmetry

Procedure: 1. Connect oscilloscope to test point TP (RF). 2. Turned Power switch on. 3. Put disc (YEDS-18) in and playback. 4. Adjust RV101 so that the waveform is clear. (Clear RF signal waveform means that the shape can be clearly distinguished at the center of the waveform.) 5. After adjustment, check the RF signal level. RF signal VOLT/DIV: 200 mV TIME/DIV: 500 nS

6. After check, remove the lead wire connected in step 2. Note: Try to measure several times to make sure than the ratio of A : B or B : A is more than 10 : 7. Take sweep time as long as possible and light up the brightness to obtain best waveform. RF Level Check
