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 identified by shading and!mark on the schematic diagrams, exploded views, and in the parts list are critical forsafe 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 identified in this manual. Follow these procedures

whenever critical components are replaced or improper operation is suspected.

ATTENTION!!

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

de lappareil, ou la couche de carbone peinte sur le tube cathodique ou au blindage du tube cathodique.

Afin deviter tout risque delectrocution provenant dun chssis sous tension, un transformateur disolement doit etre utilis lors de tout

dpannage. Le chssis de ce rcepteur est directement raccord lalimentation du secteur.

! ATTENTION AUX COMPOSANTS RELATIFS A LA SECURITE!!

Les composants identifies par une trame et par une marque!sur les schemas de principe, les vues explosees et les listes de

pieces sont dune importance critique pour la securite du fonctionnement. Ne les remplacer que par des composants Sony dontle numero de piece est indique dans le present manuel ou dans des supplements publies par Sony. Les reglages de circuit dont

limportance est critique pour la securite du fonctionnement sont identifies dans le present manuel. Suivre ces procedures lors de

chaque remplacement de composants critiques, ou lorsquun 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 dur ing 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 below.

Leakage Test

The AC leakage from any exposed metal part to earth ground an

all exposed metal parts to any exposed metal part having a retur

chassis, must not exceed 0.5 mA (500 microamperes). Leakage

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 t

instructions.

2. A battery-operated AC milliampmeter. The Data Precision 245

multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a V

or battery-operated AC voltmeter. The limit indication is 0.75

so analog meters must have an accurate low voltage scale. T

Simpsons 250 and Sanwa SH-63TRD are examples of passiv

that are suitable. Nearly all battery-operated digital multimeter

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 r

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

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

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

ohmmeter. The reading should be zero ohms.

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

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

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

line; the lamp should light at normal brilliance if the screw is at grpotential (see Figure B).

Detected Symptoms

SELF-DIAGNOSTIC FUNCTION

*If a +B overcurrent is detected, stoppage of the vertical deflection is detected simultaneously. The symptom that is diagnosed first by the

mircrocontroller is displayed on the screen.

Stopping the Standby/Timer LED Flash

Turn off the power switch on the TV main unit or unplug the power cord from the outlet to stop the STANDBY/TIMER LAMP from flashing.

Self DiagnosisSupported model

Standby/Timer LED

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

of times the LED flashes translates to a probable source of the problem. A definition of the STANDBY/TIMER LED flash indicators is listed in th

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

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 flash a set number of times to indicate the possible cause of the problem. If there is more

one error, the LED will identify the first of the problem areas.

Results for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a 0.

Self-Diagnostic Screen Display

For errors with symptoms such as power sometimes shuts off or screen sometimes goes out that cannot be confirmed, it is possible to bring

past occurrences of failure on the screen for confirmation.

To Bring Up Screen Test

In standby mode, press buttons on the Remote Commander sequentially, in rapid succession, as shown below:

Display Channel 5 Sound Volume - Power ON

Handling of Self-Diagnostic Screen DisplaySince the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen during repairs. Whe

have completed the repairs, clear the result display to 0.

Unless the result display is cleared to 0, the self-diagnostic function will not be able to detect subsequent faults after completion of the repairs

Clearing the Result Display

To clear the result display to 0, press buttons on the Remote Commander sequentially when the diagnostic screen is displayed, as shown belo

Channel 8 ENTER

Quitting the Self-Diagnostic Screen

To quit the entire self-diagnostic screen, turn off the power switch on the Remote Commander or the main unit.

Self-Diagnostic Circuit

+B overcurrent (OCP)

Occurs when an overcurrent on the +B (135V) line is detected by pin 18 of IC1301 (MB Board). If the voltage of pin 18 of IC1301 (MB Board) is

than 1V when V.SYNC is more than seven verticals in a per iod, the unit wil l automatically turn off.

I-Prot

Occurs when an absence of the vertical deflection pulse is detected by pin 17 of IC1001 (MB Board). Power supply will shut down when wavefo

interval exceeds 2 seconds.

IK (AKB)

If the RGB levels* do not balance within 2 seconds after the power is turned on, this error will be detected by IC1301 (MB Board). TV will stay

on, but there will be no picture.

*(Refers to the RGB levels of the AKB detection Ref pulse that detects 1K).

Note that this differs from enter ing the Service Mode (Sound Volume + ).

ANODE CAP REMOVAL PROCEDURE

WARNING: High voltage remains in the CRT even after the power is disconnected. To avoid electric shock, discharge CRT beforeattempting to

attempting to remove the anode cap. Short between anode and coated earth ground strap of CRT.

NOTE: After removing the anode cap, short circuit the anode of the picture tube and the anode cap to either the metal chassis, CRT shield, or

carbon painted on the CRT.

HOW TO HANDLE AN ANODE CAP

1. Do not use sharp objects which may cause damage to the surface of the anode

cap.

2. To avoid damaging the anode cap, do not squeeze the rubber covering too hard.

A material fitting called a shatter-hook terminal is built into the rubber.

3. Do not force turn the foot of the rubber cover. This may cause the shatter-hook

terminal to protrude and damage the rubber.
