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.

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.

CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardousradiation exposure.

SERVICING NOTE

NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electro-static break-down because of the potential difference generatedby the charged electrostatic load, etc. on clothing and the humanbody.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and should be handled withcare.

NOTES ON LASER DIODE EMISSION CHECKNever look into the laser diode emission from right above whenchecking it for adjustment. It is feared that you will lose your sight.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK(LCX-4R)The laser diode in the optical pick-up block may suffer electro-static break-down easily. When handling it, perform solderingbridge to the laser-tap on the flexible board. Also perform mea-sures against electrostatic break-down sufficiently before the op-eration. The flexible board is easily damaged and should be handledwith care.

OPTICAL PICK-UP FLEXIBLE BOARD

• In performing the repair with the power supplied to the set,removing the MAIN board causes the set to be disabled.In such a case, fix a convex part of the open/close detect switch(S806 on MAIN board) with a tape in advance.Handle the FLEXIBLE board (overwrite head) with care, as ithas been soldered directly to the MAIN board.In repairing the component side of MAIN board, connect theFLEXIBLE board (overwrite head) and the MAIN board withthe lead wires in advance. (See page 7)

• Replacement of CDX2671-204GA (IC801) used in this setrequires a special tool.

• On the set having the microcomputer version 1.000, someadjusted values were set in the manual mode at the shipment,but these data will be cleared when the NV is reset. Therefore,on the set having the microcomputer version 1.000, change theadjusted values following the Change of Adjusted Valuesimmediately after the NV was reset. (See page 17)

SECTION 4TEST MODE

4-3. 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 dis-

play.

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

4-4. Releasing the Test ModeFor test mode set with the method 1:Turn off the power and open the solder bridge on TAP801 (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:Turn off the power.Note: If electrical adjustment (see page 17) has not been finished

completely, always start in the test mode. (The set cannotstart in normal mode)

4-1. 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 betweenCD and MO, and each adjustment is automatically executed inorder. If a fault is found, the system displays its location. Also,the manual mode allows each individual adjustment to be auto-matically adjusted.

4-2. Setting Method of Test ModeThere are two different methods to set the test mode:1 Short TAP801 (TEST) on the MAIN board with a solder bridge

(connect pin 3 of IC801 to the ground). Then, turn on thepower.

Manual ModeMode 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, powersupply adjustment, and laser power check before performingautomatic adjustments in the Overall Adjustment mode.

• Transition method in Manual Mode1. Setting the test mode (see page 11).2. Press the > or[VOL +] key activates the manual mode where

the LCD display as shown below.

3. During each test, the optical pick-up moves outward or in-ward while the > or . key is pressed for several sec-onds respectively.

4. Each test item is assigned with a 3-digit item number;100th place is a major item, 10th place is a medium item, andunit place is a minor item.The values adjusted in the test mode are written to thenonvolatile memory (for the items where adjustment wasmade).

4-8. Self-Diagnosis Result Display ModeThis set uses the self-diagnostic function system in which if anerror occurred during the recording or playing, the mechanismcontrol block and the power supply control block in themicrocomputer detect it and record its cause as history in thenonvolatile memory.By checking this history in the test mode, you can analyze a faultand determine its location.Total recording time is recorded as a guideline of how long theoptical pickup has been used, and by comparing it with the totalrecording time at the time when an error occurred in the self-diagnosis result display mode, you can determine when the erroroccurred.Clear both self-diagnosis history data and total recording time, ifthe optical pickup was replaced.

• Self-Diagnosis Result Display Mode Setting Method

1. Setting the test mode (see page 11).2. In the display check mode, press the [ENTER] key activates the

self-diagnosis result display mode where the LCD display asshown below.

3. Then, each time the > key is pressed, LCD display descendsby one as shown below. Also, the LCD display ascends by onewhen the . key is pressed.

4. Quit the self-diagnosis result display mode, and press the x keyto return to the test mode (display check mode).

5. The display changes a shown below each time the[ENTER] key on the set is pressed.

However in the power mode (item number 700’s), only theitem is displayed.

6. Quit the manual mode, and press the x key to return to thetest mode (display check mode).

4-7. Overall Adjustment ModeMode to adjust the servo automatically in all items.Normally, automatic adjustment is executed in this mode at therepair.For further information, refer to “Section 5 Electrical Adjustments”(see page 17).
