WARNINGS AND CAUTIONS - ENGLISH
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.

! ATTENTION AUX COMPOSANTS RELATIFS A LA SECURITE!!
Les composants identifi es par une trame et par une marque ! sur les schemas de principe, les vues explosees et les listes de pieces sont d’une
importance critique pour la securite du fonctionnement. Ne les remplacer que par des composants Sony dont le numero de piece est indique dans le
present manuel ou dans des supplements publies par Sony. Les reglages de circuit dont l’importance est critique pour la securite du fonctionnement
sont identifi es dans le present manuel. Suivre ces procedures lors de chaque remplacement de composants critiques, ou lorsqu’un mauvais
fonctionnement suspecte.

SAFETY-RELATED COMPONENT WARNING
KDL-32XBR6/37XBR6
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.
KDL-32XBR6/37XBR6
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

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.

SAFETY CHECK-OUT
KDL-32XBR6/37XBR6
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.
