SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety checks before releasing the set to the customer.

1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges.

2. Check the interboard wiring to ensure that no wires are "pinched" or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair . Point them out to the customer and recommend their replacement.

4. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement.

5. Check the line cord for cracks and abrasion. Recommend the replacement of any such line cord to the customer.

6. Check the B+ voltage to see it is at the values specified.

7. Check the antenna terminals, metal trim, "metallized" knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.

T o Exposed Metal

Parts on Set

0.15 µF

1.5 kΩ

Voltmeter (0.75 V)

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 0.5mA (500 microampers). Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA TW-540A. Follo w the manufacturers' instructions to use these instruments.

2. A battery-operated A C 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 0.75V, so analog meters must have an accurate lo w volta ge 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 A C range are suitable. (See Fig. A)

WARNING!!

WHEN SERVICING, DO NO T APPRO A CH THE LASER EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS NECESSARY TO CONFIRM LASER BEAM EMISSION, BE SURE TO OBSERVE FROM A DIST ANCE OF MORE THAN 25 cm FR OM THE SURF A CE OF THE OBJECTIVE LENS ON THE OPTICAL PICK-UP BLOCK.

CAUTION:

The use of optical instrument with this product will increase eye hazard.

CAUTION

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

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.

1. REPLACING OPTICAL PICK-UP

SERVICE NOTE

1-1. Handling

A red laser diode for DVD requires more attention to static electricity than general infrared laser diodes for CD. Because its durability to static electricity is far weaker than that of infrared laser diodes, always use an earth band when handling the optical pick-up block as service parts.

Turntable (spindle motor)

1-2. When the turntable is removed, be sure to

perform the sensor adjustment.

Refer to “8. 300 CHG Mecha Con Menu 2” of Section “6. TEST MODE” (page 6-10) for the adjustment procedure.

SELF-DIAGNOSIS FUNCTION

Self-diagnosis function

When the self-diagnosis function activates to prevent the player from malfunctioning, a five-character service number (combination of a letter and digits) flashes on the screen and on the front panel display. In this case, check the following table.

C:13:00

First three characters

C13

C31

Exx (xx is any number)

Cause and/or Corrective Action

•The disc is dirty. Clean the disc with a cleaning

cloth. (page 6)

•The disc is not facing the correct

direction.

Place the disc in the slot so that

the playing side is facing left.

•The front cover will not open or close

all the way.

Remove any objects that may be

blocking the movement of the front cover.

•To prevent a malfunction, the player

has performed the self-diagnosis function. The front cover automatically open and the player enters standby mode.

When you contact your Sony dealer or local authorized Sony service facility, remove all of the discs in the player and give the 5-character service number. (example: E:61:10)
