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.

CAUTION

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

On power sources

•Use house current, nikel metal hydride rechargeable battery, LR6 (SG) battery, or car battery.

•For use in your house: For the supplied battery charging stand, use the AC power adaptor supplied with this recorder. Do not use any other AC power adaptor since it may cause the recorder to malfunction

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.

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.

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

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

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (ABX-1R)

The laser diode in the optical pick-up block may suffer electrostatic break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perform measures against electrostatic break-down sufficiently before the operation. The flexible board is easily damaged and should be handled with care.

laser-tap

•Replacement of SN761058ZQL (IC501), CDX2678-202GA (IC801) used in this set requires a special tool

•The shipment data will be cleared when the NV is reset. Therefore, change the NV adjusted values following the Change of NV Adjusted Values immediately after the NV was reset. (See page 17)

•This set requires the patch data in the nonvolatile memory (IC851) to be rewritten using the application, when the MAIN board was replaced. (See page 28)

TEST MODE

Outline

•This set provides the Overall adjustment mode that allows CD and MO discs to be automatically adjusted when in the test mode. In this overall adjustment mode, the disc is discriminate between CD and MO, and each adjustment is automatically executed in order. If a fault is found, the system displays its location. Also, the manual mode allows each individual adjustment to be automatically adjusted.

•Operation in the test mode is performed with the set. A key having no particular description in the text, indicates a set key.

•For the LCD display, the LCD on the remote commander is shown, but the contents of LCD display on the set are same. (Both displays may be displayed.)

Setting Method of Test Mode

There are three different methods to set the test mode:

1Short SL803 (TEST) on the MAIN board with a solder bridge (connect pin <zx. of IC801 to the ground) and turn on the power.

2In case of setting the test mode only by keys on the set:

In the normal mode, turn on the [HOLD] switch. While press-

ing the [GROUP] key press the following order:

> t > t . t . t > t

. t > t . t X t X

3In case of setting the test mode by keys on the set and remote commander:

In the normal mode, turn on the [HOLD] switch on the set. While pressing the x key on the set, press the keys on the remote commander with the following order:

>t > t . t . t > t

. t > t . t t

Note: If electrical adjustment (CD and MO overall adjustment) has not been finished completely, “ERROR” is displayed on LCDs of the set and the remote commander.

Operation in Setting the Test Mode

•When the test mode becomes active, first the display check mode is selected.

•Other mode can be selected from the display check mode.

•When the test mode is set, the LCD repeats the following display.

•When the X key is pressed and hold down, the display at that time is held so that display can be checked.

Releasing the Test Mode

For test mode set with the method 1:

Turn off the power and open the solder bridge on SL803 (TEST) on the MAIN board.

Note: Remove the solders completely. Remaining could be shorted with the chassis, etc.

For test mode set with the method 2 or 3: Turn off the power.

Manual Mode

Mode to adjust or check the operation of the set by function. Normally, the adjustment in this mode is not executed. However, the Manual mode is used to clear the memory, power supply adjustment, and laser power check before performing automatic adjustments in the Overall Adjustment mode.

The manual mode consists of a major item, a medium item and a minor item.

The manual mode is divided into four groups of major items.

SERVO	: item number 000	- 500, 800 -
AUDIO	: item number 600	-
POWER	: item number 700	-
OP	: item number 900	-

A medium item divides a major item and is used to select functions.

In a minor item, adjustments or operation checks are performed.

• Transition method in manual mode

1.Set the test mode (see page 11).

2.Press the > key, [VOL +] key or [VOL +] key on the remote commander activates the manual mode where the LCD display as shown below.

Normally, automatic adjustment is executed in this mode at the repair.

For further information, refer to “SECTION 5 ELECTRICAL ADJUSTMENTS” (see page 17).

MZ-N10

Self-Diagnosis Result Display Mode

This set uses the self-diagnostic function system in which if an error occurred during the recording or playing, the mechanism control block and the power supply control block in the microcomputer detect it and record its cause as history in the nonvolatile memory.

By checking this history in the test mode, you can analyze a fault and determine its location.

Total recording time is recorded as a guideline of how long the optical pick-up has been used, and by comparing it with the total recording time at the time when an error occurred in the selfdiagnosis result display mode, you can determine when the error occurred.

Clear both self-diagnosis history data and total recording time, if the optical pick-up was replaced.

• Self-diagnosis result display mode setting method

1.Set the test mode (see page 11).

2.In the display check mode, turning the jog dial (down) or pressing the [DISPLAY] key on the remote commander activates the self-diagnosis result display mode where the LCD display as shown below.
