SERVICING NOTES

ABOUT VIOLET-COLOR-TYPE

NOTES ON HANDLING THE OPTICAL PICK-UP

BLOCK OR BASE UNIT

Not a whole set of the violet-color-type is colored violet, but only

the ornamental belt and window (ornament) is violet, and the up-

per panel, the case (rear) and the battery case lid are colored sil-

ver.

The laser diode in the optical pick-up block may suffer electro-

static break-down because of the potential difference generated

by the charged electrostatic load, etc. on clothing and the human

body.

upper panel (silver)

battery case lid (silver)

During repair, pay attention to electrostatic break-down and also

use the procedure in the printed matter which is included in the

repair parts.

window (ornament)

(violet)

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.

VIOLET

The laser diode in the optical pick-up block may suffer electro-

static break-down easily. When handling it, perform soldering

bridge 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 handled

with care.

quires a special tool.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead-

free mark (LF) indicating the solder contains no lead.

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270 ˚C dur-

ing 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.

• In performing the repair with the power supplied to the set, re-

moving the MAIN board causes the set to be disabled.

In such a case, fix a convex part of the open/close detect switch

(S809 on MAIN board) with a tape in advance.

•

When entered in the TEST MODE, this set provides the Overall

Adjustment mode which allows CD and MO discs to be auto-

matically adjusted. In the OverallAdjustment mode, the system

discriminates between CD and MO discs, performs adjustments

in sequence automatically, and displays the faulty location if

any fault is found. In the Manual mode, selected adjustments

can be performed automatically.

4-2-3. How to release the TEST MODE

When method 1 was used:

Turn off the power and open the solder bridge on TAP601 on the

main board.

Note: The solder should be removed clean. The remaining solder

may make a short with the chassis and other part.

When method 2 was used:

Turn off the power.

Note: When the power supply is switched on in the state where all

electrical adjustments have not finished, it is displayed on

LCD as “NV Error’’ and the usual operation can’t be per-

formed.

When a power supply is accidentally turn off in the middle

of electrical adjustments, it is again set as test mode and elec-

trical adjustments is mode to complete.

The Self-diagnostic system is used in this set. If an error occurs

during playback, this system detects the fault through the

microprocessor’s mechanism and power control blocks and stores

the cause in EEPROM in a history format.

This history, which can be viewed in the TEST MODE, provides

the means of locating the fault in troubleshooting.
