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.

KLV-40W300A/46W300A/52W300A

SAFETY-RELATED COMPONENT WARNING

There are critical components used in LCD color TVs that are important for safety. These components are identiﬁ ed with shading and

mark on the schematic diagrams and the electrical parts list. It is essential that these critical parts be replaced only with the part number

speciﬁ ed in the electrical parts list to prevent electric shock, ﬁ re, or other hazard.

NOTE: Do not modify the original design without obtaining written permission from the manufacturer or you will void the original parts and

labor guarantee.

USE CAUTION WHEN HANDLING THE LCD PANEL

When repairing the LCD panel, be sure you are grounded by using a wrist band.

When installing the LCD panel on a wall, the LCD panel must be secured using the 4 mounting holes on the rear cover.

To avoid damaging the LCD panel:

 do not press on the panel or frame edge to avoid the risk of electric shock.

 do not scratch or press on the panel with any sharp objects.

 do not leave the module in high temperatures or in areas of high humidity for an extended period of time.

 do not expose the LCD panel to direct sunlight.

 avoid contact with water. It may cause a short circuit within the module.

 disconnect the AC adapter when replacing the backlight (CCFL) or inverter circuit.

(High voltage occurs at the inverter circuit at 650Vrms.)

 always clean the LCD panel with a soft cloth material.

 use care when handling the wires or connectors of the inverter circuit. Damaging the wires may cause a short.

 protect the panel from ESD to avoid damaging the electronic circuit (C-MOS).

LEAKAGE CURRENT HOT CHECK CIRCUIT

KLV-40W300A/46W300A/52W300A

The circuit boards used in these models have been processed using

Lead Free Solder. The boards are identified by the LF logo located

close to the board designation e.g. H1 etc [ see example ]. The

servicing of these boards requires special precautions to be taken as

outlined below.

example 1

It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality of new solder joints.

Lead Free Solder is available under the following part numbers :

Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees centigrade.

This requires soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.

For more information on the use of Lead Free Solder, please refer to

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 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).

PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS INFORMATION

All voltages are in V.

S : Measurement impossibility.

: B+line.

: B-line. (Actual measured value may be different).

: signal path. (RF)

Circled numbers are waveform references.

The components identiﬁ ed by shading and

symbol are critical for safety. Replace

only with part number speciﬁ ed.

The symbol indicates a fast operating fuse and is displayed on the component

side of the board. Replace only with fuse of the same rating as marked.

Les composants identiﬁ es per un trame et une marque

sont critiques pour la

securite. Ne les remplacer que par une piece portant le numero speciﬁ e.

Le symbole indique une fusible a action rapide. Doit etre remplace par une

fusible de meme yaleur, comme maque.

NOTE: The components identiﬁ ed by a red outline and a mark contain conﬁ dential

information. Speciﬁ c instructions must be adhered to whenever these components

are repaired and/or replaced.

See Appendix A: Encryption Key Components in the back of this manual.

All capacitors are in μF unless otherwise noted. pF : μμF 50WV or

less are not indicated except for electrolytics and tantalums.

All electrolytics are in 50V unless otherwise speciﬁ ed.

All resistors are in ohms. kΩ=1000Ω, MΩ=1000kΩ

Indication of resistance, which does not have one for rating

electrical power, is as follows: Pitch : 5mm

Rating electrical power :

W in resistance,

W and

W in chip resistance.

: nonﬂ ammable resistor

: fusible resistor

: internal component

: panel designation and adjustment for repair

: earth ground

: earth-chassis

All variable and adjustable resistors have characteristic curve B,

unless otherwise noted.

Readings are taken with a color-bar signal input.

Readings are taken with a 10MΩ digital multimeter.

Voltages are DC with respect to ground unless otherwise noted.

Voltage variations may be noted due to normal production

tolerances.
