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.
KDL-40NX720/46NX720/55NX720/60NX720 9
VÉRIFICATION DE SÉCURITÉ
Après avoir corrigé le problème de service original, effectuez les vérications de sécurité suivantes avant de remettre le
téléviseur au client :
1. Vériez le secteur de votre réparation an de vous assurer qu’il ne reste aucune connexion non soudée ou mal soudée.
Vériez toute la surface du circuit pour la présence d‘éclaboussures ou de ponts de soudure.
2. Vériez le lage inter-modules an de vous assurer qu’aucun l n’est « pincé » ou soit en contact avec des résistances à
wattage élevé.
3. Assurez-vous que tous les boutons de contrôle, écrans, couvercles, courroies de mise à la terre et équipement de xation
ont été remplacés. Soyez absolument certain d’avoir remplacé tous les isolateurs.
4. Recherchez la présence de pièces de remplacement non autorisées, surtout au niveau des transistors, qui auraient été
installés lors d’une réparation antérieure. Faites-en la remarque au client et recommandez leur remplacement.
5. Recherchez toute pièce qui, quoique fonctionnelle, fait montre de signez évidents de détérioration. Faites-en la remarque au
client et recommandez leur remplacement.

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.
4. 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).
Figure A. Using an AC voltmeter to check AC leakage.
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).

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 denition 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.

SECTION2-SOFTWAREREQUIREMENTS
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.
These updates are accessed by the customer from the Sony
Support Site at http://esupport.sony.com.
● Software update for servicers
These updates are specically for servicers to use during a
service call and are only available on the Sony Authorized
Servicer Portal at http://www.sony.com/asp.
SOFTWARE UPDATES FOR CUSTOMERS
The subject of software updates is a 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.
Software updates can be performed by:
● Customer Manual Downloads: Software updates can be
accessed by the customer from the Sony Support Site at
http://esupport.sony.com where they can be downloaded
and placed on a USB thumb drive to be loaded onto the TV.
The instructions for downloading the software le vary from
chassis to chassis and sometimes from model to model. The
customer is provided with the instructions to properly format
the USB thumb drive, unzip the le, and the procedures for
loading the software into the television.
KDL-40NX720/46NX720/55NX720/60NX720 19
SECTION 2 - SOFTWARE REQUIREMENTS
● Network Downloads: Internet software updates are
becoming more prevalent as more and more models
incorporate home network capabilities. This method is the
most practical since the television will check for the latest
version of software. The models using the this wchassis
provide the customer with a choice of turning the automatic
software update feature on or off. If set to on, the television
will lookup software information while the unit is in standby.
If a newer version is available, it will be downloaded and
installed without any input from the customer.
● Built-in Tuner: OTA or cable sources having the proper
station that is transmitting software update data packets.
Although the ability to transmit software update is possible in
this way, it is the least common and is reserved for particular
situations where a critical update is “forced”, thereby
updating the unit without any input from the customer.
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 specic 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 signicantly 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
efciently. The software update and procedures for the software
installation are located on the Sony Authorized Servicer Portal at
http://www.sony.com/asp.
In addition to software installation, service adjustment information
may need to be modied or veried to complete the service of the
TV. Service adjustment information is covered in “Section 7 - Service
Adjustments” on page 60.
KDL-40NX720/46NX720/55NX720/60NX720 20
SECTION 2 - SOFTWARE REQUIREMENTS
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 notied 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.
CHECKING THE SOFTWARE VERSION
The easiest way to check the version of software that is currently on
the TV is to access the Contact Sony screen by using the customer
menu.
EXAMPLES OF SOFTWARE CORRECTABLE SYMPTOMS
Always check the Sony Authorized Servicer Portal at http://www.
sony.com/asp site for any known and/or listed issues that are
software related. Most symptoms that are correctable by software
updates involve communications issues with other devices or minor
glitches in the operation of a specic function. Below is a list of some
of the symptoms that may be corrected with a software update:
● Fluctuations in picture brightness
● Intermittent picture freezing or noise
● Problems with certain inputs (especially HDMI)
● Intermittent or distorted audio
● Erratic remote control operation
● Unit turns on and off by itself
● Loss of color
● Internet connectivity
● Certain features not working correctly
