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 (over write head) with care, as ithas been soldered directly to the MAIN board.In repairing the component side of MAIN board, connect theFLEXIBLE board (over write head) and the MAIN board withthe lead wires in advance. (See page 8)

• Replacement of CXD2674-204GA (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 18)

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.

Caution: On the set having the microcomputer version 1.000,some adjusted values were set in the manual mode atthe shipment, but these data will be cleared when theNV is reset. Therefore, on the set having the micro-computer version 1.000, change the adjusted valuesfollowing the Change of Adjusted Values immediatelyafter the NV was reset (see page 18).

4-4. Releasing the Test ModeFor test mode set with the method 1:Turn off the power and open the solder bridge on SL801 (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 18) 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

(PB) and MO (REC/PB) disk to be automatically adjusted whenin the test mode. In this overall adjustment mode, the disc isdiscriminate between CD and MO, and each adjustment isautomatically executed in order. If a fault is found, the systemdisplays its location. Also, the manual mode allows eachindividual adjustment to be automatically adjusted.

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

• For the LCD display, the LCD on the set is shown.

4-2. Setting Method of Test ModeThere are two different methods to set the test mode:1 Short SL801 (TEST) on the MAIN board with a solder bridge

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

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 pick-up 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 pick-up was replaced.

• Self-diagnosis result display mode setting method1. Setting the test mode (see page 12).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.

If the [ENTER] key on set is pressed with this display, the LCDswitches to the simple display mode.

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.

Common note on Schematic Diagram:• All capacitors are in µF unless otherwise noted. pF: µµF

50 WV or less are not indicated except for electrolyticsand tantalums.

• All resistors are in Ω and 1/4 W or less unless otherwisespecified.

• % : indicates tolerance.• C : panel designation.

• A : B+ Line.• Total current is measured with Minidisc installed.• Power voltage is dc 3V and fed with regulated dc power

supply from external power voltage jack.• Voltage and waveforms are dc with respect to ground

under no-signal conditions.no mark : PB( ) : REC< > : TUNER

∗ : Impossible to measure• Voltages are taken with a VOM (Input impedance 10 MΩ).

Voltage variations may be noted due to normal produc-tion tolerances.

• Waveforms are taken with a oscilloscope.Voltage variations may be noted due to normal produc-tion tolerances.

• Circled numbers refer to waveforms.• Signal path.

E : PBj : REC (ANALOG)l : REC (DIGITAL)

Note: The components identified by mark 0 or dotted linewith mark 0 are critical for safety.Replace only with part number specified.
