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 (500microamperes).
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” indica-tion 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 VOMs that are suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suitable. (See Fig. A)
After correcting the original service problem, perform the fol-lowing safety checks before releasing the set to the customer:1.Check the area of your repair for unsoldered or poorly-sol-dered 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.Check that all control knobs, shields, covers, ground straps,
and mounting hardware have been replaced. Be absolutely certain that you have replaced all the insulators.
4.Look for unauthorized replacement parts, particularly tran-sistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement.
5.Look for parts which, though functioning, show obvious
signs of deterioration. Point them out to the customer and recommend their replacement.
6.Check the line cords for cracks and abrasion. Recommend
the replacement of any such line cord to the customer.
7.Check the B+ and HV to see if they are specified values.
Make sure your instruments are accurate; be suspicious of your HV meter if sets always have low HV.
8.Check the antenna terminals, metal trim, “metallized”
knobs, screws, and all other exposed metal parts for AC Leakage. Check leakage as described right.
SAFETY CHECK-OUT
WARNING!!
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY SHADING AND MARK ! ON THE SCHEMATIC DIAGRAMS, EXPLODED VIEWS AND IN THE PARTS LIST ARE CRITICAL FOR SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS AP-PEAR AS SHOWN IN THIS MANUAL OR IN SUPPLE-MENTS PUBLISHED BY SONY. CIRCUIT ADJUST-MENTS THAT ARE CRITICAL FOR SAFE OPERATION ARE IDENTIFIED IN THIS MANUAL. FOLLOW THESE PROCEDURES WHENEVER CRITICAL COMPONENTS ARE REPLACED OR IMPROPER OPERATION IS SUS-PECTED.
AVERTISSEMENT!!
ATTENTION AUX COMPOSANTS RELATIFS À LA SÉCURITÉ!!
LES COMPOSANTS IDENTIFIÉS PAR UNE TRAME ET UNE MARQUE ! SONT CRITIQUES POUR LA
SÉCURITÉ. NE LES REMPLACER QUE PAR UNE PIÈCE PORTANT LE NUMÉRO SPECIFIÉ. LES
RÉGLAGES DE CIRCUIT DONT L’IMPORTANCE EST CRITIQUE POUR LA SÉCURITÉ DU
FONCTIONNEMENT SONT IDENTIFIÉS DANS LE PRÉSENT MANUEL. SUIVRE CES PROCÉDURES LORS DE CHAQUE REMPLACEMENT DE COMPOSANTS CRITIQUES, OU LORSQU’UN MAUVAIS FONCTIONNEMENT EST SUSPECTÉ.
