SECTION 1 - SAFETY AND FEATURES
SAFETY-RELATED WARNINGS
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.
1. Do not press on the panel or frame edge to avoid the risk of electric shock.
2. Do not scratch or press on the panel with any sharp objects.
3. Do not leave the module in high temperatures or in areas of high humidity for an extended period of time.
4. Do not expose the LCD panel to direct sunlight.
5. Avoid contact with water. It may cause a short circuit within the module.
6. Disconnect the AC power when replacing the backlight or inverter circuit.
(High voltage occurs at the inverter circuit at 650Vrms.)
7. Always clean the LCD panel with a soft cloth material.
8. Use care when handling the wires or connectors of the inverter circuit. Damaging the wires may cause a short.
9. Protect the panel from ESD to avoid damaging the electronic circuit (C-MOS).
10. During the repair, DO NOT leave the Power On for more than 1 hour while the TV is face down on a cloth.

SECTION 1 - SAFETY AND FEATURES
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 on the next page.

KDL-32EX725/40EX725/46EX725/55EX725 7
SECTION 1 - SAFETY AND FEATURES
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
The cover-plate retaining screw on most AC outlet boxes is at earth ground.Verify
the AC outlet box retaining screw ground by connecting 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).

SECTION 1 - SAFETY AND FEATURES
SELF DIAGNOSIS FUNCTION
The TVs in this manual contain a self-diagnostic function. If an error occurs, the standby LED will automatically begin to ash. The number of
times the LED ashes translates to a probable source of the problem. A denition of the standby LED ash indicator is listed in the Operating
Instruction manual for the user’s 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.
For complete information, refer to “Section 4 - Troubleshooting” on page 30.

SECTION 2 - SOFTWARE REQUIREMENTS
OVERVIEW
There are 2 reasons for updating the software on the TVs.
●Software updates for customers
These updates are for enhancements or improvements that
have been made to the software after the TV was released.
●Software update for servicers
These updates are specically for servicers to use during a
service call.
SOFTWARE UPDATES FOR CUSTOMERS
The subject of software updates is very important. The televisions
of today have advanced to the point where they are not simply a
television anymore. They are evolving into devices that are designed
to integrate with numerous other devices found in the home. Some
examples are: Portable audio and video devices, still cameras, home
computer networks and accessing the internet to name a few.
Communications with these varying devices requires that the
television be compatible with varying communications protocols.
Although standards are detailed for each of these protocols, the real
world dictates that occasional errors may occur that could prevent
devices from operating or communicating properly.
Keeping the software in the television up-to-date is a procedure that
is normally handled by the owner of the television. Most customers
who own computers and other digital devices are familiar with and are
accustomed to updating the software in their products. If a customer
contacts the Sony Customer Support Center and it is deemed to
be correctable with a software update, the issue is handled at the
customer level.

SECTION 2 - SOFTWARE REQUIREMENTS
SOFTWARE UPDATES FOR SERVICERS
The models in this manual utilize a generic type Main Board. In
the past, many different Main Boards needed to be stocked due to
differences in software requirements. The software loaded on the
board was specic to the model and its features along with the type
of LCD panel installed during production.
Replacement Main Boards are now stocked with basic software.
Once the replacement board is installed in the unit, the most current
software needs to be installed using a USB thumb drive containing
the necessary software downloaded.
This new method of supplying Main Boards signicantly reduces the
complexity of replacing LCD panels and Main Boards. Information
about the LCD panel is stored on the TCON circuits. This information
is automatically loaded onto the Main Board when the TV is powered
up. With the correct software version the Main Board and/or the
TCON or LCD panel can be replaced more efciently.
In addition to software installation, service adjustment information
may need to be modied or veried to complete the service of the
TV. Service adjustment information is covered in “Section 7 - Service
Adjustments” on page 68.
SOFTWARE UPDATE RESPONSIBILITY
Software updates are designed to be performed by the customer.
Warranty repairs in which the issue can be resolved by a software
update are not reimbursable. Most issues involving software
updates are handled by the customer service center and should not
be directed to an authorized service center. It is the responsibility
of the servicer to prevent service calls for issues that involve
software updates. Exceptions to this are certain cases whereby the
customer is unable or unwilling to perform the task. In this situation,
the servicer will be notied and receive the proper authorization for
reimbursement.
It is the servicer’s responsibility, however, to make certain that any
TV requiring a legitimate service is running the latest software
version and to install it if necessary.
