SAFETY CHECK-OUT

To Exposed Metal Parts on Set
0.15 µF
Earth Ground
AC Voltmete
r
(0.75V)
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.
Figure A. Using an AC voltmeter to check AC leakage.
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-22BX320/22BX321 5
SAFETY CHECK-OUT
Trouble Light
AC Outlet Box
Ohmmeter
Cold-water Pipe
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.
Figure B. Checking for 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).

SEC 1. SOFTWARE REQUIREMENTS

1-1. OVERVIEW

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. The software
update and procedures for the software installation are located on the Sony Authorized Servicer Portal at www.sony.com/asp.
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 Sec 3. Service
Adjustments on page 20.

1-2. SOFTWARE UPDATES

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-22BX320/22BX321 12
SEC 1. SOFTWARE REQUIREMENTS

1-3. 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.

1-3-1. 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.
1-3-2. EXAMPLES OF SOFTWARE CORRECTABLE
SYMPTOMS
Always check the Sony Authorized Servicer Portal at 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 specic function. Below is a list of some of the
symptoms that may be corrected with a software update:
Î Fluctuations in picture brightness
Î Intermittent picture freezing or noise
Î Problems with certain inputs (especially HDMI)
Î Intermittent or distorted audio
Î Erratic remote control operation
Î Unit turns on and off by itself
Î Loss of color
Î Internet connectivity
Î Certain features not working correctly
