HCD-F3MD SERVICE MANUAL E Model HCD-F3MD is the Amplifier, CD player, MD Deck and Tuner section in CMT-F3MD. US and foreign patents licensed from Dolby Laboratories.
SELF-DIAGNOSIS FUNCTION The self-diagnosis function consists of error codes for customers, 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 the customer, refer to the following box in the instruction manual. For details on how to check error codes during servicing, refer to the following “Procedure for using the Self-Diagnosis Function (Error History Display Mode)”.
ITEMS OF ERROR HISTORY MODE ITEMS AND CONTENTS Selecting the Test Mode Display Details of History total rec Displays the recording time. Displayed as “rssssssh”. The displayed time is the total time the laser is set to the high power state. This is about 1/4 of the actual recording time. The time is displayed in decimal digits from 0h to 65535h. total play Displays the play time. Displayed as “pssssssh”. The time displayed is the total actual play time. Pauses are not counted.

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.

MC COLD RESET • The cold reset clears all data including preset data stored in the RAM to initial conditions. Execute this mode when returning the set to the customer. Procedure: 1. Press the I/1 button to turn the power on. 2. While pressing the [PLAY MODE/TUNING MODE] and s (CD) buttons, press the I/1 button. 3. The set is reset, and displays “COLD RESET”, then becomes standby status. MC HOT RESET • This mode resets the set with the preset data kept stored in the memory.
MD SECTION JIG FOR CHECKING BD (MD) BOARD WAVEFORM The special jig (J-2501-149-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.
Note : About “R” As this unit has only a few buttons, some operations require the use of remote commander (RM-SF3MD/provided with unit: 1-476-068-11) buttons. These operations are indicated as “R” in this manual. Example: MENU/NO “R” ...Press the [MENU/NO] button of the remote commander. IOP DATA RECORDING AND DISPLAY WHEN OPTICAL PICK-UP AND NON-VOLATILE MEMORY (IC171 ON THE BD (MD) BOARD) ARE REPLACED The IOP value labeled on the optical pick-up can be recorded in the non-volatile memory.
CHECKS PRIOR TO PARTS REPLACEMENT AND ADJUSTMENTS 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”. Criteria for Determination (Unsatisfactory if specified value is not satisfied) Measure if unsatisfactory: • 0.9 mW power Specified value : 0.84 to 0.92 mW • 7.0 mW power Specified value : 6.8 to 7.
RETRY CAUSE DISPLAY MODE • In this test mode, the causes for retry of the unit during recording can be displayed on the fluorescent indicator tube. 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.

SECTION 5 ELECTRICAL ADJUSTMENTS MD SECTION 5-1. PARTS REPLACEMENT AND ADJUSTMENT • Check and adjust the mechanism deck as follows. The procedure changes according to the part replaced • Abbreviation OP : Optical pick-up OWH : Overwrite head • Temperature compensation offset check • Laser power check • Traverse check • Focus bias check • C PLAY check • Self-recording/playback check OK NG Check the sled and spindle mechanisms. Other causes can be suspected.
Note : About “R” As this unit has only a few buttons, some operations require the use of remote commander (RM-SF3MD/provided with unit: 1-476-068-11) buttons. These operations are indicated as “R” in this manual. Example: MENU/NO “R” ...Press the [MENU/NO] button of the remote commander. 5-2. PRECAUTIONS FOR CHECKING LASER DIODE EMISSION To check the emission of the laser diode during adjustments, never view directly from the top as this may lose your eye-sight. 5-3.
5-6. CHECK PRIOR TO REPAIRS These checks are performed before replacing parts according to “approximate specifications” to determine the faulty locations. For details, refer to “Checks Prior to Parts Replacement and Adjustments” (See page 11). 5-6-1. Temperature Compensation Offset Check When performing adjustments, set the internal temperature and room temperature of 22 °C to 28 °C. Checking Procedure: 1. Press the l m or M L button to display “TEMP CHECK”. 2. Press the ENTER/YES “R” button. 3.
9. Press the ENTER/YES “R” button to display “EFB = MO-P”. Then, the optical pick-up moves to the pit area automatically and servo is imposed. 10. Observe the waveform of the oscilloscope, and check that the specified value is satisfied. Do not Press the l m or M L button. Traverse Waveform A VC B Specified value : Below 10% offset value Offset value (%) = IA – BI X 100 2 (A + B) 11. Press the ENTER/YES “R” button to display “EF MO CHECK” The disc stops rotating automatically. 12.
5-8. RECORDING AND DISPLAYING THE IOP INFORMATION The IOP data can be recorded in the non-volatile memory. The IOP value on the optical pick-up label and the IOP value after the adjustment will be recorded. Recording these data eliminates the need to read the label on the optical pick-up. Recording Procedure : 1. Press the l m or M L button to display “Iop Write”, and press the ENTER/YES “R” button. 2. The display becomes Ref=@@@.
12. Press the ENTER/YES “R” button. When the display becomes Ref=@@@.@ (@ is an arbitrary number), press the ENTER/ YES “R” button to display “Measu=@@@.@” (@ is an arbitrary number). 13. The numbers which can be changed will blink. Input the Iop value noted down at step 9. To select the number : Press the l m or M L button. To select the digit : Press the [SYNC REC] button. 14. When the ENTER/YES “R” button is pressed, “Complete!” will be displayed momentarily.
18. Press the ENTER/YES “R” button, display “EFB = SAVE” for a moment and save the adjustment results in the non-volatile memory. Next “EF CD ADJUST” will be displayed. 19. Press the A (MD) button and take out the disc. 5-12. FOCUS BIAS ADJUSTMENT Adjusting Procedure : 1. Load the continuously-recorded disc. (Refer to “5-5. CREATING CONTINUOUSLY-RECORDED DISC”) 2. Press the l m or M L button to display “CPLAY MODE”. 3. Press the ENTER/YES “R” button to display “CPLAY MID”. 4.
5-15-2. MO Auto Gain Control Output Level Adjustment Adjusting Procedure : 1. Load the test disc (MDW-74/AU-1). 2. Press the l m or M L button to display “AG Set (MO)”. 3. When the ENTER/YES “R” button is pressed, the adjustment will be performed automatically. “Complete!!” will then be displayed momentarily when the value is recorded in the non-volatile memory, after which the display changes to “AG Set (MO)”. 4. Press the A (MD) button and take out the test disc.
Note: Clear RF signal waveform means that the shape “◊” can be clearly distinguished at the center of the waveform. CD SECTION 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 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.
