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.

Details and possible causes

10 Servo Carriage Home NG The CRG cannot move toward the inner track.

The CRG cannot move from the inner track.

--> Defective HOME SW; Failure in CRG movement.

7

Servo TOC reading NG TOC information cannot be read.

--> The partial disk or TOC content is illegal.

11

Servo Focus Search NG Focusing not available

--> Disc placed upside-down; Stains on the disc; excessive vibration.

17 Servo Setup NG AGC protection does not work. Focus can be easily lost.

--> Scratches or stains on the disc; excessive vibration.

15 Servo Failure in RF data RF not read

--> A CD-R disc that does not contain data loaded

--> A CD-RW disc that does not contain data loaded

12

Servo Spindle Lock NG

Subcode NG
RF-amp NG

Spindle not locked. Subcode not readable.
Proper RF AMP gain not obtained.

--> Defective spindle; Scratches or stains on the disc; excessive vibration.

-->

A CD-R disc that does not contain data loaded, or in a rare case, disc placed upside-down.

--> CD signal error.

30

Servo Search Time Out Failed to reach a target address

--> CRG tracking error; Scratches on the disc; Stains on the disc

50 Mechanism Failure in ejection

Load NG

Disc ejection not completed
Disc loading not completed

--> A foreign object inserted in the mechanism; Disc jammed.

51

Mechanism Failure in retried

turning for ejection

Disc could not be ejected even after disc turning had been retried.

--> A foreign object inserted in the mechanism; Disc jammed.

NOTES

• Indications of error codes are available only during disc operations, because CD operations are
unavailable if a mechanical error is generated.

• If the TOC cannot be read, this is not processed as an error, and operation continues accordingly.

• If you design a new head unit, be sure to use one of the display formats indicated in “Display example of
the main unit.”

ERROR CODES

(1) DISPLAY METHOD

If “0xFD” error mode is displayed in CD MODE (CD MODE area for display), an error code will be displayed in the MIN (minute
display) and SEC (second display) areas.

The same code is displayed in the MIN and SEC areas.
The TNO area is blank (#0FFH), as it conventionally was.

• Display example of the main unit
Depending on the display capability of LCDs, the display format varies, as shown below. XX denotes an error number.
Note: In a case of an OEM product, the error display format is subject to the specifications used by the equipment
manufacturer.

If a CD memory device is inoperable, or operation of such media is stopped by an error, the error mode is established and a
cause of the error is displayed by an error code. Indication of error codes is intended to reduce the number of calls from
customers and facilitate failure analysis and repair work in servicing.

• The 2 high-order digits of an error code denote the main
classification, shown below.
0x: Servo-related errors
1x: Servo-related errors
3x: Servo-related errors
5x: Mechanism-related errors

• How to restore from each error is shown below.
0x, 1x and 3x: ACC-OFF then ON, CD-OFF then ON,
Disc ejection
5X: ACC-OFF then ON, Disc ejection, Disc reloading
