SAFETY CHECK-OUT After correcting the original service problem, perform the following safety check before releasing the set to the customer: Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. LEAKAGE The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microampers.).
CD-TEXT TEST DISC This unit is able to display the test data (character information) written in the CD on its fluorescent indicator tube. The CD-TEXT TEST DISC (TGCS-313:4-989-366-01) is used for checking the display. To check, perform the following procedure. Checking Method: 1. Turn ON the power, set the disc on the disc table with the side labeled as “test disc” as the right side, close the front cover, and chuck the disc. 2. Press the · button and play back the disc. 3.

SECTION 4 TEST MODE ADJ MODE FLUORESCENT INDICATOR TUBE, LED ALL LIT, AND KEY CHECK MODE 1. Press the I/u button to turn ON the power, and open the front cover. 2. Place the CD on the slit, close the front cover, and chuck the the CD. 3. Press the I/u button to turn OFF the power. 4 Disconnect the power supply from the outlet. 5. Short-circuit the test point (TP ADJ) and test point (TP GND) of the MAIN board with a lead wire. 6. Insert the power plug into the outlet.
AGING MODE Partially lit 1 1 DISCS G A B C D E F • Mode which repeatedly changes and plays back discs automatically in the unit. • It will repeat aging as long as no errors occur. • If an error occurs during aging, it will stop all servos, motors, etc. instantaneously, display the error number, and stop operations. However, the stopping conditions differ according to whether the unit is equipped with the “self-protection function during errors” described later.
Error Display *3 Aging cycle count function: Functions which displays the number of agings carried out on the Fluorescent indicator tube in numbers. One aging cycle Aging carried consists of six discs. 1 DISCS 40 (Hexadecimal) 1 DISCS CD1 DISC 51 Disc number TRACK 1 Error code SEC Without remote commander for aging mode: 1. Turn ON the power of the unit. Open the front cover. 2. Press the [PLAY MODE], · , and ≠ buttons in order. 3. When the disc set mode is set, the · and P LEDs blink.
SECTION 5 MECHANICAL ADJUSTMENTS To adjust the mechanism section, enter the mechanism section adjustment mode. For how to enter the mechanism section adjustment mode, refer to each adjustment section. DISC SENSOR ALIGMENT 1. Make sure that there is no disc in the unit. 2. Connect an oscilloscope to TP501 of the MAIN board. oscilloscope D.SENS (CH1) HHOUT (CH2) GND GND HHOUT D.SENS MAIN board TP501 3. While pressing the [CLEAR] and [PLUS ONE] buttons at the same time and turn ON the power.
8. Move the holder (sensor) center so that the flat portion center at the top of the D.SENS (CH1) input waveform and the ‘’H” center of HHOUT (CH2) coincide. Flat portion center of D. SENS (CH1) waveform HHOUT (CH2) waveform D.SENS (CH1) waveform Fixed screw Holder (sensor) 9. Tighten the fixed screw to fix the disc table, then press the [CLEAR] button. 10. The disc table rotates in the clockwise direction. Measure the waveform and make sure that the flat portion center at the top of the D.
MAGNET ASSY ALIGMENT 1. Check that there is no disc in the unit and then turn ON the power. Open the door, and set a disc in the PLUS ONE slit. 2. Turn OFF the power, close the door, and while pressing the [CLEAR] and [PLUS ONE] buttons simultaneously, turn ON the power again. 3. Press the [CHECK] button, and set the loading mode. 4. Press the ± button and chuck the disc. 5. Adjust the magnet assembly and magnet holder so that A=B as shown in the figure.
SECTION 6 ELECTRICAL ADJUSTMENTS 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 10MΩ 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. 11. Turn OFF the power, and remove the lead wire connected at step 7.
When a general remote commander is not used: 1. Solder lead wires to TP (DVDD) and TP (TOFF) on the BD board severally. 2. Connect the oscilloscope to TP (TE) of the BD board. 3. Press the I/u button and turn ON the power supply. 4. Open the front cover, and press the [PLUS ONE] button. 5. Set the disc (YEDS-18) into the “PLUS ONE” slit. 6.
