SAFETY CHECK-OUT

After correcting the original service problem, perform the following

safety check before releasing the set to the customer:

Check the antenna terminals, metal trim, “metallized” knobs, screws,

and all other exposed metal parts for AC leakage.

Check leakage as described below.

LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground and

from all exposed metal parts to any exposed metal part having a

return to chassis, must not exceed 0.5 mA (500 microamperes.).

Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA

WT-540A. Follow the manufacturers’instructions to use these

instruments.

2. A battery-operated AC milliammeter. The Data Precision 245

digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a

VOM or battery-operated AC voltmeter. The “limit” indication

is 0.75 V, so analog meters must have an accurate low-voltage

scale. The Simpson 250 and Sanwa SH-63Trd are examples

of a passive VOM that is suitable. Nearly all battery operated

digital multimeters that have a 2 V AC range are suitable. (See

Fig. A)

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.

CAUTION

Use of controls or adjustments or performance of procedures

otherthanthosespecifiedhereinmayresultin hazardous radiation

exposure.

UNLEADED SOLDER

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

free 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 viscou-s (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.

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

The laser beam on this model is concentrated so as to be focused on

the disc reflective surface by the objective lens in the optical pick-

up block. Therefore, when checking the laser diode emission,

observe from more than 30 cm away from the objective lens.

SECTION 1

SERVICING NOTES

This appliance is classified as a

CLASS 1 LASER product.

The CLASS 1 LASER PRODUCT

MARKING is located on the rear

exterior.

Laser component in this product is capable of emitting radiation

exceeding the limit for Class 1.

NOTES ON HANDLING THE OPTICAL PICK-UP

BLOCK OR BASE UNIT

ANTITHEFT LOCK MODE

This mode is used to unable to take sample disc out of disc table in

the shop.

Procedure:

1. Press the @/1 button to turn the power on.

2. Press the CD

u

button to select “CD”.

3. Press two buttons of xCANCEL and Zfor 5 seconds.

4. The message “CD LOCKED” is displayed on the fluorescent

indicator tube and the disc slot is locked. (Even if pressing

the Zbutton, the message “CD LOCKED” is displayed on

the fluorescent indicator tube and the disc table is locked.)

5. To releasefromthismode,presstwo buttonsof xCANCEL and

Zfor 5 seconds.

6. The message “CD UNLOCKED” is displayed on the fluores-

cent indicator tube and the disc table is unlocked.

*Replacement of USB board IC8 and BT board IC905

used in this set requires a special tool.

•The voltage and waveform of CSP (chip size package) cannot

be measured, because its lead layout is different from that of

conventional IC.

•Lead layouts

Note on USB board replacement

New part of EEP ROM (IC6) on the USB board cannot be used. Therefore,

if the mounted USB board (X-2149-040-1) is replaced, exchange new

EEP ROM (IC6) with that used before the replacement.
