HCD-PX333 SECTION 1 SERVICING NOTES 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.
HCD-PX333 SERVICE POSITION • In checking the MD mechanism deck section (MDM-7X2A), prepare two extension jigs (Part No. J-2501-100-A: 1.00 mm 27 core and Part No. J-2501-198-A: 1.00 mm 17 core). • In checking the CD mechanism deck section (CDM55A-21BD53), prepare extension jig (Part No. J-2501-075-A: 1.00 mm 21 core.) Connect extension jig (J-2501-198-A) to the BD (MD) board (CN103) and MD DIGITAL board (CN1004).
HCD-PX333 JIG FOR CHECKING BD (MD) BOARD WAVEFORM The special jig (J-2501-196-A) is useful for checking the waveform of the BD (MD) board. The names of terminals and the checking items to be performed are shown as follows.
HCD-PX333 Note 1: About “R” As this unit has only a few buttons, some operations require the use of remote commander (RM-S55EN/provided with unit: 1-476-664-21) buttons. These operations are indicated as “R” in this manual. Example: MENU/NO “R” ... Press the [MENU/NO] button of the remote commander. Note 2: Incorrect operations may be performed if the MD test mode is not entered properly. In this case, press the ?/1 button to turn the power off, and retry to enter the MD test mode.
HCD-PX333 CHECKS PRIOR TO PARTS REPLACEMENT AND ADJUSTMENTS IN MD Before performing repairs, perform the following checks to determine the faulty locations up to a certain extent. Details of the procedures are described in “5 Electrical Adjustments”.
HCD-PX333 RETRY CAUSE DISPLAY MODE IN MD • In this test mode, the causes for retry of the unit during recording can be displayed on the liquid crystal display. During playback, the “track mode” for obtaining track information will be set. This is useful for locating the faulty part of the unit. • The following will be displayed : During recording and stop : Retry cause, number of retries, and number of retry errors. During playback : Information such as type of disc played, part played, copyright.

(3) Press the ENTER/YES “R” button to change the display to “CPLAY2MID”. (4) When access completes, the display changes to “C = AD = )”. Note: The numbers “ ” displayed show you error rates and ADER. 2.
HCD-PX333 7. TEST MODE DISPLAYS Each time the [CD SYNC HIGH] button is pressed, the display changes in the following order. When CPLAY or CREC are started, the display will forcibly be switched to the error rate display as the initial mode. 1. Mode display Displays “TEMP ADJUST” (C03), “CPLAY2MODE” (C36), etc. Mode display 2. Error rate display Displays the error rate in the following way. C= AD = ) C = : Indicates the C1 error. AD = : Indicates ADER.
HCD-PX333 8. AUTOMATIC SELF-DIAGNOSIS FUNCTION This test mode performs CREC and CPLAY automatically for mainly checking the characteristics of the optical pick-up. To perform this test mode, the laser power must first be checked. Perform AUTO CHECK after the laser power check and Iop Compare. Procedure: 1. Press the . “R” or > “R” button to display “AUTO CHECK” (C01). 2. Press the ENTER/YES “R” button. If “LDPWR ” is displayed, it means that the laser power check has not been performed.
HCD-PX333 SECTION 5 ELECTRICAL ADJUSTMENTS MD SECTION Note 1: About “R” As this unit has only a few buttons, some operations require the use of remote commander (RM-S55EN/provided with unit: 1-476-664-21) buttons. These operations are indicated as “R” in this manual. Example: MENU/NO “R” ...Press the [MENU/NO] button of the remote commander. Note 2: Incorrect operations may be performed if the MD test mode is not entered properly.
