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.

FOR CD

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.

FOR MD

NOTES ON LASER DIODE EMISSION CHECK

Never look into the laser diode emission from right above when checking it for adjustment. It is feared that you will lose your sight.

Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.

This appliance is classified as a CLASS 1 LASER product. This label is located on the rear exterior.

The following caution label is located inside the apparatus.

CAUTION

Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

Notes on chip component replacement

•Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be damaged by heat.

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 viscous (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.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

5. Press the > “R” button to display “Iop Write” (C05) and press the ENTER/YES “R” button.

6. The display becomes “Ref=@@@.@” (@ is an arbitrary number) and the numbers which can be changed will blink.

7. Input the Iop value written on the optical pick-up. To select the number : Press the . “R” button or the > “R” button. To select the digit : Press the REC MODE button.

8. When the ENTER/YES “R” button is pressed, the display becomes “Measu=@@@.@” (@ is an arbitrary number).

9. As the adjustment results are stored for the 6 value. Leave it as it is and press the ENTER/YES “R” button.

10. “Complete!” will be displayed momentarily. The value will be stored in the non-volatile memory and the display will become “Iop Write” (C05).

11. Press the REPEAT “R” button to exit the mode.

12. Press the ?/1 button to turn off the power.

Display Precedure:

1. Press the ?/1 button to turn on the power.

2. Press the FUNCTION button to select the “MD” function.

3. While pressing the x button and the ENTER/START button at the same time, press the FUNCTION button.

4. Press the > “R” button to display “[Service]”. Then press the ENTER/YES “R” button.

5. Press the > “R” button to display “Iop Read” (C26) and press the ENTER/YES “R” button.

6. “@@.@/##.#” is displayed and the recorded contents are displayed. @@.@ : indicates the Iop value labeled on the optical pick-up ##.# : indicates the Iop value after adjustment

7. To end, press the MENU/NO “R” button to display “Iop Read” (C26). Then press the REPEAT “R” button.

8. Press the ?/1 button to turn off the power.

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 “Section 5 Electrical Adjustments”.

Laser power check (6-2 : See page 34)

Auto check (6-4 : See page 35)

Temperature compensation offset check (6-1 : See page 34)

Criteria for Determination (Unsatisfactory if specified value is not satisfied)

• 0.93 mW power Specified value : 0.84 to 0.92 mW (KMS-262A)

0.90 to 0.96 mW (KMS-262E)

• 8.65 mW power Specified value : 8.1 to 8.7 mW (KMS-262A)

8.4 to 8.9 mW (KMS-262E)

• Iop (at 8.65 mW) Labeled on the optical pick-up Iop value ± 10mA

• Unsatisfactory if displayed as “NG : XXXX”NG (XXXX are arbitrary numbers)

• Unsatisfactory if displayed as “T=@@ (##) [NG]” NG (@@, ## are both arbitrary numbers)

• Clean the optical pick-up

• Adjust again

• Replace the optical pick-up

• Check for disconnection of the circuits around D101 (BD (MD) board)

• Check the signals around IC101, IC151, CN102, CN103 (BD (MD) board)

Measure if unsatisfactory

Note:

The criteria for determination above is intended merely to determine if satisfactory or not, and does not serve as the specified value for adjustments. When performing adjustments, use the specified values for adjustments.

7. 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. Display “AUTO CHECK” and press the ENTER/YES “R” button. If “LDPWR check has not been performed. In this case, perform the laser power check and Iop Compare (C27), and then repeat from step1.

2. If a disc is in the mechanical deck, it will be ejected forcibly. “DISC IN” will be displayed in this case. Load a test disc (MDW-74/GA-1) which can be recorded.

3. If a disc is loaded at step 2, the check will start automatically.

4. When “XX CHECK” is displayed, the item corresponding to XX will be performed. When “06 CHECK” completes, the disc loaded at step 2 will be ejected. “DISC IN” will be displayed. Load the check disc (TDYS-1).

5. When the disc is loaded in step 4, the check will automatically be resumed from “07 CHECK”.

6. After completing to “0C CHECK”, check OK or NG will be displayed. If all items are OK, “CHK ALL OK” will be displayed. If any item is NG, it will be displayed as “NG:xxxx”.

When “CHK ALL OK” is displayed, it means that the optical pick-up is normal. Check the operations of other parts (spindle motor, sled motor, etc.). When displayed as “NG:xxxx”, it means that the optical pick-up is faulty. In this case, replace the optical pick-up.
