SECTION 1 SERVICING NOTES NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT
MODEL IDENTIFICATION – Back Panel –
The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down 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.
MODEL NUMBER LABEL
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. UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size) : LEAD FREE MARK Unleaded solder has the following characteristics. • Unleaded solder melts at a temperature about 40 °C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350 °C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! • Strong viscosity Unleaded solder is more viscou-s (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. • Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

CD ERROR CODE The past errors of the CD mechanism (CDM) are displayed as the CDM Errors, and those of the optical pick-up system (= optical unit + CD board) are displayed as the BD Errors as shown below. Procedure: 1. Press the [I/1] button to turn the power on. 2. Press the [FUNCTION] button to select CD function. 3. Press three buttons of [TUNING + M L], [x] and [DISPLAY] simultaneously. 4. Then, the CDM error code is displayed as “M0xxxxxx” (x means hexadecimal number) on the liquid crystal display as shown below. 5. Every pressing of the [TUNING + M L] button in this mode increments the number after “M” starting from “M0” up to “M9”, and then returns to “M0”. Every pressing of the [l m – TUNING] button in this mode decrements the number after “M”. The smaller the error code number is, the newer the error content is. 6. When the [USB SYNC REC/REC 1] button is pressed then, the BD error code is displayed as “D0xxxxxx” (x means hexadecimal number) on the liquid crystal display as shown below. In the same way as the CDM error code, use of the [TUNING + M L] and the [l m – TUNING] buttons in this mode enables tracing of the error history. 7. To release from this mode, press the [I/1] button to turn the power off.

CD SECTION Note: 1. CD Block is basically constructed to operate without adjustment. 2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10 MΩ 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. 5. Check the focus bias check when optical pick-up block is replaced.
