MDS-JE470 SECTION 1 SERVICE NOTES SAFETY CHECK-OUT (US model only) 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.
MDS-JE470 JIG FOR CHECKING BD BOARD WAVEFORM The special jig (J-2501-196-A) is useful for checking the waveform of the BD board. The names of terminals and the checking items to be performed are shown as follows.
MDS-JE470 Iop DATA RECORDING AND DISPLAY WHEN OPTICAL PICK-UP AND NON-VOLATILE MEMORY (IC195 OF BD BOARD) ARE REPLACED The Iop value labeled on the optical pick-up can be recorded in the non-volatile memory. By recording the value, it will eliminate the need to look at the value on the label of the optical pick-up. When replacing the optical pick-up or non-volatile memory (IC195 of BD board), record the Iop value on the optical pick-up according to the following procedure. Record Precedure: 1.
MDS-JE470 OPTICAL PICK-UP BLOCK TYPE DISCRIMINATION There are two types of the optical pick-up block in this model. These are compatible except for the laser power. Check the type of the optical pick-up block before replacement. Ajdust following items after replacing the optical pick-up block. • 5-6-2. Laser Power Check (See page 28) • 5-10.
MDS-JE470 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”. • 5-6-2. Laser power check (see page 28) • 5-6-3. Iop Compare (see page 28) • 5-6-4.
MDS-JE470 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.
MDS-JE470 Reading the Display: Convert the hexadecimal display into binary display. If more than two causes, they will be added. Example When 42 is displayed: Higher bit : 4 = 0100 t b6 Lower bit : 2 = 0010 t b1 In this case, the retry cause is combined of “CLV unlock” and “ader5”. When A2 is displayed: Higher bit : A = 1010 t b7+b5 Lower bit : 2 = 0010 t b2 The retry cause in this case is combined of “access fault”, “IVR rec error”, and “ader5”.

MDS-JE470 SECTION 4 TEST MODE 4-1. PRECAUTIONS FOR USE OF TEST MODE • As loading related operations will be performed regardless of the test mode operations being performed, be sure to check that the disc is stopped before setting and removing it. Even if the A EJECT button is pressed while the disc is rotating during continuous playback, continuous recording, etc., the disc will not stop rotating. Therefore, it will be ejected while rotating.
MDS-JE470 4-5. SELECTING THE TEST MODE There are 26 types of test modes as shown below. The groups can be switched by rotating the l AMS L knob. After selecting the group to be used, press the YES button. After setting a certain group, rotating the l AMS L knob switches between these modes. Refer to “Group” in the table for details selected. All adjustments and checks during servicing can be performed in the test mode in the Service group. NOTE: Do not use the test mode in the [Develop] group.

MDS-JE470 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. PRECAUTIONS FOR USE OF OPTICAL PICKUP (KMS-260B/260E) 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, desolder first. Before connecting the connector, be careful not to remove the solder.
MDS-JE470 5-5. USING THE CONTINUOUSLY RECORDED DISC * This disc is used in focus bias adjustment and error rate check. The following describes how to create a continuous recording disc. 1. Insert a disc (blank disc) commercially available. 2. Rotate the l AMS L knob and display “CREC1 MODE”. 3. Press the YES button again to display “CREC1 MID”. Display “CREC (0300)” and start to recording. 4. Complete recording within 5 minutes. 5. Press the MENU/NO button and stop recording . 6.
MDS-JE470 5-6-4. Auto Check This test mode performs C-REC and C-PLAY 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 YES button. If “LDPWR minicheck” is displayed, it means that the laser power check has not been performed. In this case, perform the laser power check and Iop compare, and then repeat from step 1. 2.
MDS-JE470 16. Observe the waveform of the oscilloscope, and check that the specified value is satisfied. Do not rotate the l AMS L knob. (Traverse Waveform) A VC B Specified value : Below 10% offset value Offset value (%) = IA – BI X 100 2 (A + B) 17. Press the YES button and display “EF CD CHECK”. 18. Press the A EJECT button and remove the check disc (MD) TDYS-1. Note 1 : MO reading data will be erased during if a recorded disc is used in this adjustment.
MDS-JE470 5-7. INITIAL SETTING OF ADJUSTMENT VALUE 5-9. TEMPERATURE COMPENSATION OFFSET ADJUTMENT Note: Mode which sets the adjustment results recorded in the non-volatile memory to the initial setting value. However the results of the temperature compensation offset adjustment will not change to the initial setting value. If initial setting is performed, perform all adjustments again excluding the temperature compensation offset adjustment. For details of the initial setting, refer to “5-4.
MDS-JE470 7. Then, rotate the l AMS L knob and display “LDPWR CHECK”. 8. Press the YES button once and display “LD 0.9 mW $ ”. Check that the reading of the laser power meter become the specified value. 9. Press the YES button once more and display “LD 7.0 mW $ ”. Check that the reading the laser power meter and digital volt meter satisfy the specified value. Note down the digital voltmeter reading value. Specified Value : Laser power meter reading : LD 0.9mW : 0.85-0.91mW (260B) 0.90-0.96mW (260E) LD 7.
MDS-JE470 11. Rotate the l AMS L knob until the waveform of the oscilloscope moves closer to the specified value. In this adjustment, waveform varies at intervals of approx. 2%. Adjust the waveform so that the specified value is satisfied as much as possible. (Traverse Waveform) A VC B Specification A = B 12. Press the YES button, and save the adjustment results in the non-volatile memory. (“EFB = SAVE” will be displayed for a moment.) Next “EF MO ADJUS” is displayed.
