Caution
These servicing instructions are for use by quali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 qualied to do so.
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.
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 identied by shading and ! mark on the exploded views are critical for safe operation.
Replace all components with Sony parts whose part numbers appear as shown in this manual or in supplements published by Sony. It is
essential that all critical parts be replaced only with the part number specied in this manual to prevent electric shock, re, or other hazard.
Circuit adjustments that are critical for safe operation are identied in this manual.
Follow these procedures whenever critical components are replaced or improper operation is suspected.
NOTE: Do not modify the original design without obtaining written permission from the manufacturer or you will void the original parts and
labor guarantee.

attEntion!!
Ces instructions de service sont à l’usage du personnel de service quali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 qualié faire ainsi.
pour 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.
alErtE!!
A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 identi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 identies dans le present manuel. Suivre ces procedures lors de chaque remplacement de composants
critiques, ou lorsqu’un mauvais fonctionnement suspecte.
WARNING AND cAUTIONS

KDL-32EX301/32EX400/40EX400/40EX401 5
SAFETY-RELATED WARNING
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.
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 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).
10) During the repair, DO NOT leave the Power On for more than 1 hour while the TV is face down on a cloth.

After correcting the original service problem, perform the following safety checks before releasing the set to the customer:
SAFETY CHECK-OUT
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.
