WARNINGS AND CAUTIONS

CAUTION

Short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield, or carbon painted on the CRT,

after removing the anode.

WARNING!!

An isolation transformer should be used during any service to avoid possible shock hazard, because of live chassis. The chassis of

this receiver is directly connected to the ac power line.

! SAFETY-RELATED COMPONENT WARNING!!

Components identiﬁ ed 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 appear as shown in this manual or in supplements

published by Sony. Circuit adjustments that are critical for safe operation are identiﬁ ed in this manual. Follow these procedures

whenever critical components are replaced or improper operation is suspected.

ATTENTION!!

Apres avoir deconnecte le cap de l’anode, court-circuiter l’anode du tube cathodique et celui de l’anode du cap au chassis metallique

de l’appareil, ou la couche de carbone peinte sur le tube cathodique ou au blindage du tube cathodique.

Aﬁ n d’eviter tout risque d’electrocution provenant d’un chássis sous tension, un transformateur d’isolement doit etre utilisé lors de tout

dépannage. Le chássis de ce récepteur est directement raccordé à l’alimentation du secteur.

! ATTENTION AUX COMPOSANTS RELATIFS A LA SECURITE!!

Les composants identiﬁ es par une trame et par une marque

!

sur les schemas de principe, les vues explosees et les listes de

pieces sont d’une importance critique pour la securite du fonctionnement. Ne les remplacer que par des composants Sony dont

le numero de piece est indique dans le present manuel ou dans des supplements publies par Sony. Les reglages de circuit dont

l’importance est critique pour la securite du fonctionnement sont identiﬁ es dans le present manuel. Suivre ces procedures lors de

chaque remplacement de composants critiques, ou lorsqu’un mauvais fonctionnement suspecte.

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

touching 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 transistors,

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 speciﬁ ed 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 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

instructions.

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’s 250 and Sanwa SH-63TRD are examples of passive

VOMs that are suitable. Nearly all battery-operated digital multimeters

that have a 2 VAC range are suitable (see Figure A).

How to Find a Good Earth Ground

A cold-water pipe is a guaranteed earth ground; the cover-plate retaining

screw on most AC outlet boxes is also at earth ground. If the retaining

screw is to be used as your earth ground, verify that it is at ground

by measuring the resistance between it and a cold-water pipe with an

ohmmeter. The reading should be zero ohms.

If a cold-water pipe is not accessible, connect a 60- to 100-watt trouble-

light (not a neon lamp) between the hot side of the receptacle and the

retaining screw. Try both slots, if necessary, to locate the hot side on the

line; the lamp should light at normal brilliance if the screw is at ground

potential (see Figure B).

SELF-DIAGNOSTIC FUNCTION

The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED will automatically begin to ﬂ ash. The number

of times the LED ﬂ ashes translates to a probable source of the problem. A deﬁ nition of the STANDBY/TIMER LED ﬂ ash indicators is listed in the

instruction manual for the user’s knowledge and reference. If an error symptom cannot be reproduced, the Remote Commander can be used to review

the failure occurrence data stored in memory to reveal past problems and how often these problems occur.

Diagnostic Test Indicators

When an error occurs, the STANDBY/TIMER LED will ﬂ ash a set number of times to indicate the possible cause of the problem. If there is more than

one error, the LED will identify the ﬁ rst of the problem areas.

Results for all of the following diagnostic items are displayed on screen. If the screen displays a “0”, no error has occurred.

(FINE ADJUSTMENT)

If the jig described below is available, it is recommended that the G2

Fine Mode Adjustment be performed to set the screen controls to their

optimal condition. If desired, you can build the jig illustrated below,

using 3-watt resistors. Please note that if the proper voltage is not
