WARNINGS AND CAUTIONS

CAUTION

These servicing instructions are for use by qualifi ed service personnel only. To reduce the risk of electric shock, do not perform any

☛

servicing other than that contained in the operating instructions unless you are qualifi ed to do so.

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!!

Ces instructions de service sont à l’usage du personnel de service qualifi é seulement. Pour prévenir le risque de choc électrique, ne

☛

pas faire l’entretien autre que celui contenu dans le Mode d’emploi à moins que vous soyez qualifi é faire ainsi.

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

KDF-55WF655/60WF655

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 milliampmeter. 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

Self Diagnosis

Supported model

The units in this manual contain a self-diagnostic function. If an error occurs, the POWER/STANDBY or LAMP 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 POWER/STANDBY or LAMP LED fl ash
indicators is listed in the instruction manual for the user’s knowledge and reference. If an error symptom is diffi cult to reproduced use the Remote
Commander to display the record that is stored at the internal NVM to specify the cause of the failure.

Diagnostic Test Indicators

When an error occurs, the POWER/STANDBY or LAMP 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. If the errors occur simultaneously, the one that corresponds to the fewest
fl ashes is identifi ed fi rst.
Results for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a “0”.

Self-Diagnostic Circuit

Self-Diagnosis Function Operation

3 : Lamp cover The rib at the back of the lamp cover closes the SW on the T board to ground pin 3 of CN8001.

It is monitored by the DE-micro (pin 94 of IC6902) and turns off the lamp when it is opened.

4 : Fan Fan rotation is detected by "FAN-PROT" and the DE-micro (pin 92 of IC6902) turns off the lamp

when it is "high".

4 : Temp When the temperature sensor on the H3 board (WE models) or H4 board (WF/XS models)

detects high temperature, or IIC-E line connector (CN6022:G2 board, CN44:H3board/H4board)
is not seated securely, the DE-micro turns off the lamp.

5 : Lamp driver When the "LAMP-PROT" (pin 95) is low, the lamp is not turned on. If the "LAMP-HV-DET"

6 : Low B error When no "DD 6V " is detected, pin 129 of TV-micro is low and it turns off the main power.

(pin 96) is low at the same time, it is classified as no high voltage of the lamp driver.

7 : Audio When DC voltage is detected at the speaker or woofer outputs, pin 128 of TV-micro is low and it

turns off the main power.

8 : D-OVP When overvoltage of "+3.3V" or "+2.5V" is detected, pin 126 of TV-micro is low and it turns off

the main power.

10 : ATSC-OVP When no "Digital Module 5V" is detected, pin 127 of TV-micro is low and it turns off the main

power.

LAMP : Lamp When the "LAMP-PROT" (pin 95) is low, the lamp is not turned on. If the

"LAMP-HV-DET" (pin96) is high at the same time, it is classified as no lamp or a dead lamp.
