SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0OR DOTTED LINEWITH
MARK 0ON 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.
This appliance is classified as a CLASS 1 LASER product. The
CLASS 1 LASER PRODUCT MARKING is located on the rear
exterior.
Laser component in this product is capable
of emitting radiation exceeding the limit for
Class 1.
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 DVD
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 pick-
up 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.
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.
This caution
label is
located inside
the unit.

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 stored in the non-volatile memory. By storing 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), store the Iop
value on the optical pick-up according to the following procedure.
Record Precedure:
1. Press the ?/1button to turn on the power.
2. Press the FUNCTION button to select the “MD” function.
3. While pressing the xbutton and the REC MODE button at the same time, press the FUNCTION button.
4. Press the MD >“R” button to display “[Service]”. Then press the ENTER/YES “R” button.
5. Press the MD >“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 MD .“R” button or the MD >“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 button twice to exit the mode.
12. Press the ?/1button 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 xbutton and the REC MODE button at the same time, press the FUNCTION button.
4. Press the MD >“R” button to display “[Service]”. Then press the ENTER/YES “R” button.
5. Press the MD >“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 button twice.
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”.
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.
•0.93 mW power
Specified value : 0.85 to 0.91 mW (KMS-260B)
0.80 to 0.96 mW (KMS-260E)
•7.25 mW power
Specified value : 6.8 to 7.2 mW (KMS-260B)
7.0 to 7.5 mW (KMS-260E)
•Iop (at 7.25mW)
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)
Laser power check
(6-2 : See page 36)
Auto check
(6-4 : See page 37)
Temperature
compensation
offset check
(6-1 : See page 36)
Criteria for Determination
(Unsatisfactory if specified value is not satisfied)
•Clean the optical pick-up
•Adjust again
•Replace the optical pick-up
•Replace the optical pick-up
•Replace the optical pick-up
•Check for disconnection of the circuits around
D101 (BD board)
•Check the signals around IC101, IC151, CN102,
CN103 (BD board)
Measure if unsatisfactory
