On power sources

•

For use in your house: Use the AC power adaptor supplied with this recorder. Do not use any other AC power adaptor since it may cause the recorder to malfun ction.

Polarity of the plug

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.

Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270 ˚C

during repairing.

• Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering

or unsoldering.

CAUTION

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

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.

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.

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 viscou-s (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.

NOTES ON REPLACEMENT OF CSP (CHIP SIZE PACKAGE) IC

Replacement of MM1690NCBE (IC401), SN761059AZQLR (IC501), SC901585VAR2 (IC601) and CXD2681-225GG (IC801) used in this set requires a special tool.

OPERATION CHECK WHEN THE MAIN BOARD IS REMOVED

In making an operation check with the MAIN board removed from the set, short the SL894 of the MAIN board with the solder before starting the operation check.

Note: Be sure to remove the solder used for shortcircuit after the repaire

completed.

3-6. Servo Overall Adjustment

Note1: Be sure to adjustment so that the set is horizontal and the LCD is

upside. Unless performed in that state, it is not adjusted correctly.

Note2: If NG is displayed in the middle of this adjustments, perform “3-2.

Initialize The Adjustment Value” and “3-5. Setting The Adjustment Values” again, then retry this adjustments from step 1.

Procedure:

1. Enter the test mode (Display Check mode).

2. Press the [VOL--] key to enter the Overall Adjustment mode.

3. Insert the CD adjustment disc (TDYS-1).

4. Put the main unit horizontal so that the LCD becomes upside, and press the . key.

5. Wait until “CD OK” is displayed on the LCD.

6. Insert the MD1/HiMD1 hybrid adjustment disc (MDW-74/GA2).

7. Put the main unit horizontal so that the LCD becomes upside, and press the > key.

8. Wait until “MD1 OK” is displayed on the LCD.

9. Insert the Hi-MD3 adjustment disc (HMD1GSDJ).

10. Put the main unit horizontal so that the LCD becomes upside, and press the [VOL+] key.

11. Wait until “HMD3OK” is displayed on the LCD.

12. Eject the disc and close the lid.

13. Put the main unit horizontal so that the LCD becomes upside, and press the [VOL--] key.

14. Wait until “OfstOK” is displayed on the LCD.

15. Press the x key and back to the Display Check mode.

3-7. Resume Clear

Procedure:

1. Enter the test mode (Display Check mode).

2. Press the [VOL+] key to enter the Manual mode.

3. Press the [VOL+] key once, press the

> key once, press the

[VOL--] key once, press the > key once, and press the [VOL+] key twice, press the > key three times to select the item number 1933.

4. Press the X key on the set or – key on the remote commander to resume clear.

5. Press the x key four times and back to the Display Check mode.

3-8. Releasing The Test Mode

Note: When the power supply is switched on in the state where all

electrical adjustments have not finished, it is displayed on LCD as “Error EE’’ and the usual operation can’t be performed. When a power supply is accidentally turn off in the middle of electrical adjustments, it is again set as test mode and electrical adjustments is mode to complete.
