SELF-DIAGNOSIS FUNCTION
The self-diagnosis function consists of error codes for users which are displayed automatically when errors occur, and error codes which show the error history in the test mode during servicing. For details on how to view error codes for users, refer to the following box in the instruction manual. For details on how to perform checks during servicing, refer to the following "Procedure for Using the Self-Diagnosis Function (Error History Display Mode)".
Procedure for Using the Self-Diagnosis Function (Error History Display Mode) Note: Perform the self-diagnosis function in the "error history display mode" in the test mode. The following describes the least required steps. Be careful not to enter other modes by mistake. If other modes are set accidentally, press the ^ (CD) button to exit that mode. 1. 2. 3. 4. 5. 6. 7. 8. With the power off, press the ^ (MD) button while pressing the PLAY MODE button. Rotate the VOLUME knob until "ERR DP MODE" is displayed. Pressing the p (CD) button sets the error history mode and displays "total rec". Select the contents to be displayed or executed using the VOLUME knob. Pressing the 6 (CD) button displays or executes the contents selected. Pressing the 6 (CD) button another time returns to step 4. Pressing the ^ (CD) button displays "ERR DP MODE" and exits the error history mode. To exit the test mode, press the REPEAT button. The unit sets into the STANDBY state, and the test mode ends.

ITEMS OF ERROR HISTORY MODE ITEMS AND CONTENTS
Selecting the Test Mode Display total rec Details of History Displays the recording time in the form of "rh". The displayed time is the total number of hours the laser is high power, which is about one-fourth of the actual recording time. The time is displayed in decimal digits between 0h to 65535h. Displays the playback time in the form of "ph". The displayed time is the total actual play time. The paused time is not counted. The time is displayed in decimal digits between 0h to 65535h. Displays the total number of retries during recording and retry errors during playback in the form of "rp". "r" indicates the retries during recording while "p" indicates the retry errors during playback. The number of retries is displayed in hexadecimal digits between 00 to FF. Displays the total number of errors in the form of "total ". The number of errors is displayed in hexadecimal digits between 00 to FF. Displays the 10 latest errors in the form of "0 E@@". The indicates the history number. The smaller the number, the newer is the error. (00 is the latest error.) The @@ indicates the error code. Refer to the following table for details. Rotate the VOLUME knob to switch the error history. Mode which erases all the error histories. The error history serves as a reference for when to replace the optical pick-up. Perform this procedure when the optical pick-up has been replaced in order to erase past error histories and not at other times. Press the p (CD) button when "er refresh??" is displayed. The history will be erased and "Complete!" will be displayed momentarily.

SAFETY CHECK-OUT After correcting the original service problem, perform the following safety checks 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). Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers' instructions to use these instruments. 2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The "limit" indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A)

SECTION 1 SERVICING NOTE
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT 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. 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 three times.

SECTION 6 ELECTRICAL ADJUSTMENTS
MD SECTION 6-1. PRECAUTIONS FOR CHECKING LASER DIODE EMISSINON
When checking the emission of the laser diode during adjustments, never view directly from the top as this may cause blindness. Note : When performing laser power checks and adjustment (electrical adjustment), use of the new MD laser power meter 8010S (J-2501-145-A) instead of the conventional laser power meter is convenient. It sharply reduces the time and trouble to set the laser power meter sensor onto the objective lens of the pick-up.
6-2. PRECAUTIONS FOR USE OF OPTICAL PICKUP (KMS-260A)
As the laser diode in the optical pick-up is easily damaged by static electricity, solder the laser tap of the flexible board when using it. Before disconnecting the connector, solder first. Before connecting the connector, be careful not to remove the solder. Also take adequate measures to prevent damage by static electricity. Handle the flexible board with care as it breaks easily.

6-4. CREATING THE CONTINUOUSLY RECORDED DISC
· The disc is used for the focus bias adjustment and error rate check. The following describes how to create a continuously recorded disc. 1. Insert a disc (blank disc) commercially available. 2. Rotate the VOLUME knob to display "CREC MODE". 3. Press the p (CD) button to display "CREC MID". "CREC (0300)" will be momentarily displayed and recording started. 4. Complete recording within 5 minutes. 5. Press the ^ (CD) button and stop recording . 6. Press the 6 (MD) button and remove the disc. Create the continuous recorded disc for adjusting the focus bias and checking the error rate as described above. Note : · Be careful not to apply vibrations during continuous recording.

6-5. TEMPERATURE COMPENSATION OFFSET ADJUSTMENT
Save the current temperature data in the non-volatile memory as the 25 °C standard data. Notes: 1. Normally, this adjustment should not be preformed. 2. Set the surrounding temperature to 22 to 28 °C when performing this adjustment. Also perform this adjustment immediately after the power is turned on when the internal temperature of the unit is the same as the surrounding temperature (22 to 28 °C). 3. After replacing D101, perform this adjustment after the temperature of parts reach the surrounding temperature. Adjusting Procedure: 1. Rotate the VOLUME knob, to display "TEMP ADJUST". 2. Press the p (CD) button and select the "TEMP ADJUST" mode. " and the current temperature data are displayed. 3. "TEMP= 4. To save the data: Press the p (CD) button.
