ATTENTION AUX COMPOSANTS RELATIFS A LA SECURITE!!
Il ya des composants essentiels utilisés dans les téléviseurs LCD couleur qui sont importants pour la sécurité. Ces
composants sont identifiés à l’ombrage et
!
marque sur les schémas et la liste des pièces électriques. Il est essentiel que
ces parties critiques être remplacé uniquement avec le numéro de pièce figurant dans la liste des pièces électriques pour
éviter les chocs électriques, d’incendie ou autre danger.
NOTE: Ne pas modifier la version originale sans obtenir la permission écrite du fabricant ou que vous annulera les pièces
d’origine ainsi que la garantie du travail.
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 orifices de fixation
présents au couvercle arrière.
Pour éviter d’endommager l’écran LCD:
1) N’appuyez par sur le bord du panneau ou du cadre afin 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

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.

voltage élevé se produit dans le circuit inverseur à 650Vrms).
7) Nettoyez toujours le panneau ACL avec un chiffon doux.

d’endommager les films peut causer un court-circuit.
9) Protégez le panneau des décharges électrostatiques afin 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

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 in “Leakage Test”.
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. Follow the
manufacturers’ instructions provided with the
tester.
2. A battery-operated AC milliammeter.
3. Measuring the voltage drop across a resistor
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. Nearly all battery-operated
digital multimeters that have a 2 VAC range
are suitable. (see Figure A)

Figure A. Use an AC voltmeter to check AC leakage.
HOW TO FIND A GOOD EARTH GROUND
The cover-plate retaining screw on most AC outlet boxes
is at earth ground. Verify the AC outlet box retaining screw
ground by connecting a 60W to 100W incandescent (not
a neon lamp or fluorescent 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)

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.

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 :
Lead Free Solder is available under the following part numbers :
Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees celsius.
This requires soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.
