WARNINGS AND CAUTIONS
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
To avoid dropping the TV and causing serious injury, be sure to follow these guidelines:
s Before carrying the TV, disconnect all cables. s Carrying the large size TV requires two or more people. s When you carry the TV, place your hand as illustrated and hold it
securely. Do not put stress on the LCD panel.
s When lifting or moving the TV, hold it firmly from the bottom. Place
your palm directly under the panel.
s When carrying, do not subject the TV to shocks or vibration, or
excessive force.
s Place your palm directly underneath, but do not squeeze the
panel’s speaker grill area.
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!!
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.
POUR TRANSPORTER LE TÉLÉVISEUR
Assurez-vous de suivre ces consignes pour éviter de laisser tomber le téléviseur et de provoquer des blessures graves :
s Avant de transporter le téléviseur, débranchez tous les câbles. s Le transport du téléviseur doit être effectué par au moins deux
personnes.
s Lorsque vous le transportez, placez vos mains tel que cela est illustré
et tenez solidement l’appareil. N’appliquez pas de pression sur l’écran ACL.
s Lorsque vous levez ou déplacez le téléviseur, assurez-vous de tenir
solidement de la base. Placez la paume des mains directement sous le panneau.
s Lorsque vous transportez le téléviseur, ne le soumettez pas à des
chocs ou vibrations, ni à une force excessive.
s Positionnez votre paume directement sous l’appareil et veillez à
ne pas exercer de pression contre la grille des haut-parleurs du panneau.
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.
! 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-40SL140/46SL140
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-40SL140/46SL140
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

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.
