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 a tray, and chuck the disc. 2. Press the button and play back the disc. 3. The following will be displayed on the fluorescent indicator tube. Display : 1KHZ/0 DB 4. Rotate AMS knob to switch the track. The text data of each track will be displayed. For details of the displayed contents for each track, refer to Table 1 : CD-TEXT TEST DISC Recorded Contents and Display. Restrictions in CD-TEXT Display In this unit, some special characters will not be displayed properly. These will be displayed as a space or a character resembling it. Table 1 : CD-TEXT TEST DISC Recorded Data Contents and Display (TRACKS No. 1 to 32:Normal Characters) TRACK No.

SECTION 1 SERVICING NOTE

HOW TO OPEN THE DISC TRAY WHEN POWER SWITCH TURNS OFF NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic breakdown and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the S curve check in CD section adjustment and check that the S curve waveform is output two times.
Insert a screwdriver into the aperture of the unit bottom, and move it in the direction of arrow.

The following operations are performed in the ADJ mode, which is set by connecting the TP21 (ADJ) terminal to the Ground and turning on the power. During playback, there is no problem even if the GFS is continuously LOW. High speed search is prohibited during access. During playback, the gain of focus servo and spindle servo does not decrease. Servo related manual operations and measurement can be performed. (For details of operations, refer to Table of Key Operations in ADJ Mode.)

Check the level B of the oscilloscope's waveform and the A (DC voltage) of the center of the Traverse waveform. Confirm the following : A/B x 100 = less than 22%
