SAFETY-RELATED WARNINGS
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 backlight 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).
10. During the repair, DO NOT leave the Power On for more than 1 hour while the TV is face down on a cloth.

AVERTISSEMENTS DE SÉCURITÉ
FAITES ATTENTION LORS DE LA MANIPULATION DE L’ÉCRAN ACL
Au moment de réparer l’écran ACL, assurez-vous d’être mis à la terre à l’aide d’un bracelet à cet effet.
Au moment d’installer le panneau ACL sur un mur, il doit être maintenant en place à l’aide des 4 orices de xation présents au
couvercle arrière.
1. N’appuyez par sur le bord du panneau ou du cadre an d’éviter le risque de choc électrique.
2. Ne rayez pas ou n’appuyez pas sur le panneau avec des objets pointus.
3. Ne laissez pas le module exposé à des températures élevées ou dans des secteurs à haut niveau d’humidité pour une
période prolongée.
4. N’exposez pas le panneau ACL à l’ensoleillement direct.
5. Évitez le contact avec l’eau, car elle peut causer un court-circuit dans le module.
6. Déconnectez l’alimentation c.a. au moment de remplacer le rétroéclairage ou le circuit inverseur (Un voltage élevé se produit
dans le circuit inverseur à 650Vrms).
7. Nettoyez toujours le panneau ACL avec un chiffon doux.
8. Faites attention lors de la manipulation des ls ou connecteurs du circuit inverseur. Le fait d’endommager les lms peut
causer un court-circuit.
9. Protégez le panneau des décharges électrostatiques an d’éviter d’endommager le circuit électronique (C-MOS).
10. Pendant la réparation, NE LAISSEZ PAS l’alimentation en fonction pendant plus de 1 heure pendant que l’écran du téléviseur
repose sur un tissu.

SECTION 1 - SAFETY AND FEATURES
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.

KDL-46HX820/55HX820 10
SECTION 1 - SAFETY AND FEATURES
VÉRIFICATION DE SÉCURITÉ
Après avoir corrigé le problème de service original, effectuez les vérications de sécurité suivantes avant de remettre le
téléviseur au client :
1. Vériez le secteur de votre réparation an de vous assurer qu’il ne reste aucune connexion non soudée ou mal soudée.
Vériez toute la surface du circuit pour la présence d‘éclaboussures ou de ponts de soudure.
2. Vériez le lage inter-modules an de vous assurer qu’aucun l n’est « pincé » ou soit en contact avec des résistances à
wattage élevé.
3. Assurez-vous que tous les boutons de contrôle, écrans, couvercles, courroies de mise à la terre et équipement de xation
ont été remplacés. Soyez absolument certain d’avoir remplacé tous les isolateurs.
4. Recherchez la présence de pièces de remplacement non autorisées, surtout au niveau des transistors, qui auraient été
installés lors d’une réparation antérieure. Faites-en la remarque au client et recommandez leur remplacement.
5. Recherchez toute pièce qui, quoique fonctionnelle, fait montre de signez évidents de détérioration. Faites-en la remarque au
client et recommandez leur remplacement.
6. Vériez la présence de ssures et d’abrasions sur les cordons. Recommandez le remplacement de ces cordons au client.
7. Vériez les terminaux d’antenne, les garnitures en métal, les boutons « métallisés », les vis et autres pièces en métal
exposées pour toute fuite de courant. Vériez les fuites de la façon décrite ci-dessous.

KDL-46HX820/55HX820 11
SECTION 1 - SAFETY AND FEATURES
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.
4. 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 DIAGNOSIS FUNCTION
The TVs in this manual contain a self-diagnostic function. If an error occurs, the standby LED will automatically begin to ash. The number of
times the LED ashes translates to a probable source of the problem. A denition of the standby LED ash indicator is listed in the Operating
Instruction manual for the user’s 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.
For complete information, refer to “Section 4 - Troubleshooting” on page 33.
