1. SERVICE PRECAUTIONS

1.1SERVICE PRECAUTIONS

1.You should conform to the regulations governing the product (safety, radio and noise, and other regulations), and should keep the safety during servicing by following the safety instructions described in this manual.

2.Before disassembling the unit, be sure to turn off the power. Unplugging and plugging the connectors during power-on mode may damage the ICs inside the unit.

3.To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment (shorting-solder) by referring to "the DISASSEMBLY".

4.After replacing the pickup unit, be sure to check the grating.

5.Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by electrostatic induction.

1.2NOTES ON SOLDERING

A

B

C

For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.

Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering.

Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of the soldering iron.

Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting temperatures (hard to melt/easy to harden).

The following lead-free solders are available as service parts:

Parts numbers of lead-free solder:

GYP1006 1.0 in dia.

GYP1007 0.6 in dia.

GYP1008 0.3 in dia.

5.2ERROR CODE LIST

-Error Messages

If a CD is not operative or stopped during operation due to an error, the error mode is turned on and cause(s) of the error is indicated with a corresponding number. This arrangement is intended at reducing nonsense calls from the users and also for facilitating trouble analysis and repair work in servicing.

(1) Basic Indication Method

1)When SERRORM is selected for the CSMOD (CD mode area for the system), error codes are written to DMIN (minutes display area) and DSEC (seconds display area). The same data is written to DMIN and DSEC. DTNO remains in blank as before.

2)Head unit display examples

Depending on display capability of LCD used, display will vary as shown below. xx contains the error number.

			8-digit display			6-digit display			4-digit display
			ERROR-xx			ERR-xx			E-xx
(2) Error Code List
Code	Class		Displayed error code		Description of the code and potential cause(s)
10	Electricity		Carriage Home NG		CRG can't be moved to inner diameter.
			SERVO LSI Com-		CRG can't be moved from inner diameter.
			munication Error		-> Failure on home switch or CRG move mechanism.
					Communication error between microcomputer and SERVO LSI.
11	Electricity		Focus Servo NG		Focusing not available.
					-> Stains on rear side of disc or excessive vibrations on REWRITABLE.
12	Electricity		Spindle Lock NG		Spindle not locked. Sub-code is strange (not readable).
			Subcode NG		-> Failure on spindle, stains or damages on disc, or excessive vibrations.
					A disc not containing CD-R data is found.
					Turned over disc are found, though rarely.
					CD signal error.
17	Electricity		Setup NG		AGC protection doesn't work. Focus can be easily lost.
					-> Damages or stains on disc, or excessive vibrations on REWRITABLE.
30	Electricity		Search Time Out		Failed to reach target address.
					-> CRG tracking error or damages on disc.
44	Electricity		ALL Skip		Skip setting for all track.
					(CD-R/RW)
50	Mechanism		CD On Mech Error		Mechanical error during CD ON.
					-> Defective loading motor, mechanical lock and mechanical sensor.
A0	System		Power Supply NG		Power (VD) is ground faulted.
					-> Failure on SW transistor or power supply (failure on connector).

Remarks: Mechanical errors are not displayed (because a CD is turned off in these errors). Unreadable TOC does not constitute an error. An intended operation continues in this case. Upper digits of an error code are subdivided as shown below:

1x: Setup relevant errors, 3x: Search relevant errors, Ax: Other errors.

• As for the double speed (2x), audio output cannot be supported

*) • After the [Eject] key is pressed keys other than the [Eject] key should not be pressed, until disc ejection is complete.

• When the key [2] or [3] is pressed during the Focus Search, the power supply should be immediately turned off (otherwise the lens

sticks to Wall, causing the actuator to be damaged).

F

• In the case of TR jump other than to 100TR, the function shall continue to be processed even if the TR jump key is released. As for

the CRG Move and 100TR Jump, the mechanism shall be set to the Tracking Close mode when the key is released.

• When the power is turned on/off the jump mode is reset to the Single TR (91) while the gain of the RFAMP is reset to 0 dB. At the

same time all the self-adjusting values shall return to the default setting.
