Sony KDL-46XBR10 / KDL-52XBR10 Service Manual ▷ View online

KDL-46/52XBR10 (UC)     3
CAUTION
These servicing instructions are for use by qualified 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.
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.
CARRYING THE TV
Be sure to consider the following while carrying the TV:
• Disconnect all cables when carrying the TV.
• Carry the TV with the adequate number of people; larger 
size TVs require two or more people.
• Correct hand placement while carrying the TV is very 
important for safety and to avoid damage.
SETTING U P THE TV
Be sure to consider the following while setting up the TV:
• Ensure your TV has adequate ventilation.
• For best picture quality, do not expose the screen to direct 
illumination or sunlight.
• Avoid installing the TV in a room with refl ective wall and 
fl oor materials.
• Avoid moving the TV from a cold area to a warm area. 
Sudden room temperature changes may cause moisture 
condensation. This may cause the TV to show poor picture 
and/or poor color. Should this occur, allow moisture to 
evaporate completely before powering the TV on.
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.
Replace all components with Sony parts whose part numbers 
appear as shown in this manual or in supplements
published by Sony.
WARNINGS AND CAUTIONS - ENGLISH
KDL-46/52XBR10 (UC)     4
ATTENTION!!
Ces instructions de service sont à l’usage du personnel de service 
qualifi  é seulement. Pour prévenir le risque de choc électrique, 
ne pas faire l’entretien autre que celui contenu dans le Mode d’
emploi à moins que vous soyez qualifi  é faire ainsi.
WARNING!!
Afi  n d’eviter tout risque d’electrocution provenant d’un chássis 
sous tension, un transformateur d’isolement doit etre utilisé lors 
de tout dépannage. Le chássis de ce récepteur est directement 
raccordé à l’alimentation du secteur.
TRANSPORTER LE  TÉLÉVISEUR
Tenez compte de ce qui suit pendant l’installation du téléviseur :
• Débranchez tous les câbles avant de transporter le téléviseur.
• Transportez le téléviseur avec le nombre de personnes 
approprié ; un téléviseur de grande taille doit être transporté 
par au moins deux personnes.
• Lors du transport du téléviseur, l’emplacement des mains est 
très important pour votre sécurité, ainsi que pour éviter de 
causer des dommages.
INSTALLATION DU MONITEUR
Tenez compte de ce qui suit pendant l’installation du moniteur :
• Assurez-vous que le moniteur est entouré d’une ventilation 
adéquate.
• Pour obtenir une qualité d’image optimale, n’exposez pas l’
écran à la lumière directe d’une lampe ou du soleil.
• Évitez d’installer le moniteur dans une pièce dont le sol et 
les murs sont d’un matériau réfl échissant.
• Évitez de déplacer le moniteur d’un endroit froid à un 
endroit chaud. Un changement soudain de température 
peut provoquer de la condensation. Ce phénomène peut 
affecter la qualité de l’image et/ou des couleurs affi chées 
par le moniteur. Si cela se produit, laissez la condensation 
s’évaporer complètement avant de mettre le moniteur sous 
tension.
 ATTENTION AUX COMPOSANTS RELATIFS
A LA SECURITE!!
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.
WARNINGS AND CAUTIONS - FRENCH
KDL-46/52XBR10 (UC)     5
It is essential that all 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 repairing the LCD panel on the 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 (CCFL) 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).
SAFETY-RELATED COMPONENT WARNING

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 below.   
 
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. 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).
