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.

CARRYING THE TV

Be sure to follow these guidelines to protect your property and avoid causing serious injury.

• Before carrying the TV, disconnect all cables.

• Carrying the large size TV requires two or more people.

• When carrying the TV, place your hand as illustrated and hold it securely. Do not subject the TV to shocks, vibration, or excessive force.

• Lift the TV by placing your palm directly underneath the panel but do not:

• squeeze the speaker grill area

• place your fingers in the groove above the speaker grill area

• put stress on the LCD panel.

• Do not lift the TV from the bottom center.

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.

SAFETY-RELATED COMPONENT WARNING

KLV-52V410A/52W410A

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).

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.

KLV-52V410A/52W410A

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 :

rebmuntraP retemaiD skrameR

91-500-046-7mm3.0gK52.0

02-500-046-7mm4.0gK05.0

12-500-046-7mm5.0gK05.0

22-500-046-7mm6.0gK52.0

32-500-046-7mm8.0gK00.1

52-500-046-7mm2.1gK00.1

62-500-046-7mm6.1gK00.1

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

KLV-52V410A/52W410A

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.

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

The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY LED indicator 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 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.

1. Diagnostic Test Indicators

When an error occurs, the STANDBY LED indicator will ﬂ ash a set number of times to indicate the possible cause of the problem. If there is more than one error, the indicator will identify the ﬁ rst of the problem areas.
