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 2V AC range are suitable. (See Fig. A)

SAFETY-RELATED COMPONENT WARNING!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

SERVICING NOTES

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.

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 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 viscous (sticky, less prone to ﬂ ow) 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.

CAUTION

Use of controls or adjustments or performance of procedures other than those speciﬁ ed herein may result in hazardous radiation exposure.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT

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 ﬂ exible 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 reﬂ ective 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.

This appliance is claassiﬁ ed as a CLASS 1 LASER product. This label is located on the rear exterior.

1)

MP3 (MPEG 1 Audio Layer 3) is a standard format deﬁ ned by ISO/MPEG which compresses audio data. MP3 audio tracks must be in MPEG 1 Audio Layer 3 format.

2)

A logical format of ﬁ les and folders on CD-ROMs, deﬁ ned by ISO (International Organization for Standardization).

3)

This is a recording method that enables adding of data using the Track-At-Once method. Conventional discs begin at a disc control area called the Lead-in and end at an area called Lead-out. A Multi Session disc is a disc having multiple sessions, with each segment from Lead-in to Lead-out regarded as a single session.

NOTE OF REPLACING THE IC102 AND IC4605 ON THE DMB21 BOARD

IC102 and IC4605 on the DMB21 board cannot exchange with single. When these parts on the DMB21 board are damaged, exchange the entire mounted board.

NOTE OF REPLACEMENT OF THE MS-214 BOARD

When the MS-214 board is defective, exchange the entire MD (AU) ASSY.

MAIN BOARD DISCRIMINATION

In this set, the MAIN board has been changed in the midway of production. Repair after distinguishing each type set to doing the repair referring to the following.

– MAIN Board (Component Side) –

SUFFIX-11 : 1-883-863-11 SUFFIX-12 : 1-883-863-12

NOTE OF REPLACING THE IC103 AND C242 (Combination: TYPE B) ON THE MAIN BOARD (Sufﬁ x-12)

IC103 and C242 (Combination: TYPE B) on the MAIN board (Sufﬁ x-12) cannot exchange with single. When these parts on the MAIN board (Sufﬁ x-12) are damaged, remove IC103 and C242 (Combination: TYPE B) and replace with IC102 and C239 (Combination: TYPE A)

TEST MODE

HCD-SH2000

PANEL TEST MODE

This mode is used to check the ﬂ uorescent indicator tube, LEDs, keys, [MASTER VOLUME] jog, model, destination and software version.

Procedure:

1. Press [SEARCH] button and [OPTIONS] button simultaneously and hold 3 seconds.

2. All LEDs and segments in ﬂ uorescent indicator tube will light up.

3. When you want to enter to the software version display mode, press [FLANGER] button. The model information appears on the ﬂ uorescent indicator tube. Press [FLANGER] button again to view the destination information.

4. During the destination information display, press [FLANGER] button. Each time [FLANGER] button is pressed, the ﬂ uorescent indicator tube shows the version of each category software in the following sequence: SC, MTK (DMB Board ﬁ rmware version), UI, PF, SYS, CD, CDMA, CDMB, ST, TA, TAS, TM and return back to model information display.

5. When [SEARCH] button is pressed while the version numbers are being displayed except model and destination, the date of the software creation appears. When [SEARCH] button is pressed again, the display returns to the software version display.

6. Press [ISOLATOR] button, the key check mode is activated.

7. In the key check mode, the ﬂ uorescent indicator tube displays “K 0 V0”. Each time a button is pressed, “K” value increases. However, once a button has been pressed, it is no longer taken into account.

“V” value increases in the manner of 0, 1, 2, 3 ... if [MAS-

TER VOLUME] knob is turned clockwise, or it decreases in the manner of 0, 9, 8, 7 ... if [MASTER VOLUME] knob is turned counterclockwise.

8. When [SOUND FLASH] button is pressed after all LEDs and segments in ﬂ uorescent indicator tube light up, alternate segments in ﬂ uorescent indicator tube and LEDs would light up. If you press [SOUND FLASH] button again, another half of alternate segments in ﬂ uorescent indicator tube and LEDs would light up. Pressing [SOUND FLASH] button again would cause all segments in ﬂ uorescent indicator tube and LEDs light OFF. Pressing [SOUND FLASH] button again would cause all segments in ﬂ uorescent indicator tube and all LEDs light up.

9. To release from this mode, press the [SEARCH] button and [OPTIONS] button in the same manner as step 1, or disconnect the power cord.

COMMON TEST MODE

This mode is used to check operations of the Ampliﬁ er section.

Procedure:

To enter Common Test Mode
