    PRECAUCIONES DE SEGURIDAD

    ADVERTENCIA: Antes de dar servicio a este chasis, lea "PRECAUCIONES RESPECTO A RADIACION POR RAYOS X","INSTRUCCIONES DE SEGURIDAD" y "AVISO SOBRE SEGURIDAD DE PRODUCTOS"

    Muchas de las partes, electricas y mecnicas en este chasis tienen caracteristicas relacionadas con la seguridad. Estascaracteristicas frecuentemente pasan desapercibidas en las inspecciones visuales y la proteccion que proporcionan contra laRADIACION DE RAYOS-X no siempre necesariamente se obtiene al mismo grado cuando se reemplazan piezas o componentesdiseados para voltajes o vatajes mayores, etc. Las piezas que tienen estas caracteristicas de seguridad se identifican por lamarca impresa sobre el diagrama esquematico y la marca impresa en la lista de partes. Antes de reemplazar alguno deesos componente, lea cuidadosamente la lista de este manual. El uso de partes de reemplazo que no tengan las mismascaracteristicas de seguridad, como se especifica en la lista de partes, puede crear Radiacion de Rayos-X.

    1. Cuando el receptor est en operacin, se producen voltajespotencialmente tan altos como 25,000-29,000 voltios. Operarel receptor fuera de su gabinete o con la tapa traseraremovida puede causar peligro de choque elctrico.(1)Nadie debe intentar dar servicio si no est debidamente

    familiarizado con las precauciones que son necesariascuando se trabaja con un equipo de alto voltaje.

    (2)Siempre descargue el nodo del tubo de la imagen a tierrapara evitar el riesgo de choque elctrico antes de removerla tapa del nodo.

    (3)Descargue completamente el alto potencial del tubo deimagen antes de manipularlo. El tubo de la imagen es dealto vaco y, si se rompe, los fragmentos de vidrio salendespedidos violentamente.

    2. Si se quemara algn fusible de este receptor de televisin,reemplcelo con otro especificado en la lista de partes.

    3. Cuando reemplace tableros o plaquetas de circuitos,cuidadosamente enrolle sus alambres alrededor de lasterminales antes de soldar.

    4. Cuando reemplace un resistencia de vataje (resistor depelcula de xido metlico) en el Tablero o Plaqueta decircuitos, mantenga la resistencia a un mnimo de 10mm dedistancia.

    5. Mantenga los alambres lejos de componentes de alto voltajeo de alta temperatura.

    6. Este receptor de televisin debe conectarse a una fuente de100 a 240 V AC.

    7. Antes de devolver este aparato al cl iente, haga unaverificacin de fuga de corriente sobre las partes metlicasdel gabinete expuestas, tales como antenas, terminales,cabezas de tornillos, tapas de metal, palancas de control etc.,para estar seguro de que el equipo funciona sin peligro dechoque elctrico. Enchufe el cordn directamente altomacorriente de la lnea de AC 100-240V.

    No utilice una lnea aislada de transformador durante estaverificacin. Use un voltmetro de 1000 Ohmios por voltiode sensibilidad o ms, en la forma que se describe acontinuacin.Cuando la unidad est ya conectada a la AC, pulse elconmutador primero ponindolo en "ON" (encendiendo) yluego en "OFF" (apagando), mida desde un punto de tierraconocido, tal como una (caera de metal, una manijametlica, una tubera etc.) a todas las partes metlicasexpuestas del receptor de televisin (antenas, manijas demetal, gabinetes de metal, cubiertas de metal, palancas decontrol etc.,) especialmente cualquiera de las partesmetlicas expuestas que puedan ofrecer un camino hacia elchasis. Ninguna medicin de corriente elctrica debe excederde 0.5 miliamperios. Repita la prueba cambiando la posicindel enchufe en el tomacorriente. Cualquier medicin que noest dentro de los lmites especificados aqu representan unriesgo potencial de choque elctrico que debe ser eliminadoantes de devolver el equipo al cliente.

    INSTRUCCIN DE AJUSTE

    1. Application RangeThese instructions are applied to all of the LCD TV, LP81AChassis.

    2. Notice2.1 Because this is not a hot chassis, it is not necessary to

    use an isolation transformer. However, the use ofisolation transformer will help protect test instrument.

  • 5. Adjusting the White Balance5.1 Purpose and Principle for adjustment of the

    color temperature - Purpose : Adjust the color temperature to reduce the

    deviation of the module color temperature.- Principle : To adjust the white balance without the

    saturation,(Fix the one of R/G/B gain to C0 and decrease the others.)

    5.2 Adjustment mode : Two modes of Cool and Warm(Medium data is automatically calibrated by theCool data)

    O Required Equipments- Remote controller for adjustment - Color Analyzer : CA100+ or CA-210 or same product

    LCD TV( ch : 9 ),- Auto W/B adjustment instrument(only for Auto adjustment)

    5.3 Connecting diagram of equipment formeasuring (For Automatic Adjustment)

    (1) Enter the adjustment mode of DDC- Set command delay time : 50ms- Enter the DDC adjustment mode at the same time heat-- Maintain the DDC adjustment mode with same condition

    of Heat-run -> Maintain after AC off/on in status of Heat-run pattern

    display)

    (2) Release the DDC adjustment mode- Release the adjust mode after AC off/on or std-by off/on

    in status of finishing the Hear-run mode- Release the Adjust mode when receiving the aging off

    command(F3 00 00) from adjustment equipment- Need to transmit the aging off command to TV set after

    finishing the adjustment.- Check DDC adjust mode release by exit key and

    release DDC adjust mode

    (3) Enter the adjust mode of white balance- Enter the white balance adjustment mode with aging

    command(F3, 00, FF)

    * Luminance min value is 200cd/ in the cool mode( ForLCD)

    6. Adjustment of White Balance Adjustment mode : Two modes (Cool and Warm)(Medium data is automatically calibrated by the Cool data) Color analyzer(CA100+, CA210) should be used in the

    calibrated ch by CS-1000(LCD : CH9, PDP : CH10)

    Operate the zero-calibration of the CA100+ or CA-210, thenstick sensor to the module when adjusting.

    For manual adjustment, it is also possible by the followingsequence.

    1) Select white pattern of heat-run by pressing "POWER ON"key on remote control for adjustment then operate heat runlonger than 15 minutes. (If not executed this step, the condition for W/B may bedifferent.)

    2) Push "Exit" key.3) Change to the AV mode by remote control.(Push front-AV

    or Input key)4) Input external pattern(85% white pattern)5) Push the ADJ key two times (entering White Balance

    mode)6) Stick the sensor to the center of the screen and select

    each items (Red/Green/Blue Gain and Offset) using /(CH +/-) key on R/C..

    7) Adjust R/ G/ B Gain using / (VOL+/-) key on R/C.8) Adjust two modes (Cool and Warm)

    (Fix the one of R/G/B and change the others)9) When adjustment is completed, Exit adjustment mode

    using EXIT key on R/C.
