SAFETY CHECK-OUT

SPECIAL COMPONENT NOTICE

After correcting the original service problem, perform the following

safety checks before releasing the set to the customer:

CAUTION

Ensure that this product is disconnected from the power plug

before the laser protective housing is removed.

The components identified by mark contain confidential

information.

Strictly follow the instructions whenever the components are

repaired and/or replaced.

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 power cable for cracks and abrasion. Recommend

the replacement of any such power cable to the customer.

6.ChecktheB+voltagetoseeitisatthevaluesspeciied.

7. Check the 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

microampers.).

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)

WARNING!!

WHEN SERVICING, DO NOT APPROACH THE LASER

EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS

NECESSARY TO CONFIRM LASER BEAM EMISSION,

BE SURE TO OBSERVE FROM A DISTANCE OF

MORE THAN 25 cm FROM THE SURFACE OF THE

OBJECTIVE LENS ON THE OPTICAL PICK-UP BLOCK.
