Notes on chip component replacement

• Never reuse a disconnected chip component.

Q

• 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 other than those specified herein may result in hazardous radiation

SAFETY CHECK-OUT

After correcting the original service problem, perform the following

0

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 manuf acturers’ 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 v oltmeter . The “limit” indication is 0.75 V, so analog meters must hav e an accurate low-v oltage 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 A C range are suitable. (See Fig. A)

SECTION 1

SERVICING NOTES

Ver. 1.5

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 pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.

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

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40 ˚C higher

• Strong viscosity

Caution: The printed pattern (copper foil) may peel away if

the heated tip is applied for too long, so be careful!

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.

It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

LASER DIODE AND FOCUS SEARCH OPERATION CHECK

Q

During normal operation of the equipment, emission of the laser diode is prohibited unless the upper lid is closed while turning ON the S820. (push switch type) The following checking method for the laser diode is operable.

• Method

Emission of the laser diode is visually checked.

1. Open the upper lid.

2. Push the S820 as shown in Fig.1.

Note: Do not push the detection lever strongly, or it may be bent or damaged.

3. Press the u button.

4. Check the object lens for confirming normal emission of the laser diode. If not emitting, there is a trouble in the automatic power control circuit or the optical pick-up. In this operation, the object lens will move up and down 2

operation as normal (SHUF) Play.

Notes on Repeat Play

• All tracks or ﬁles on a disc are played repeatedly up to ﬁve times.

• “REPEAT 1” indicates that a single track or ﬁle is repeated until you stop it.

Notes on playing MP3 discs

• Do not save other types of ﬁles or unnecessary folders on a disc that has MP3 ﬁles.

• Folders that have no MP3 ﬁles are skipped.

• MP3 ﬁles are played back in the order that they are recorded onto the disc.

• The system can only play MP3 ﬁles that have a ﬁle extension of “.MP3.”

• If there are ﬁles on the disc that have the “.MP3” ﬁle extension, but that are not MP3 ﬁles, the unit may produce noise or may malfunction.
