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

1. Cuando el receptor está en operación, se producen voltajes potencialmente tan altos como 25,000-29,000 voltios. Operar el receptor fuera de su gabinete o con la tapa trasera removida puede causar peligro de choque eléctrico. (1) Nadie debe intentar dar servicio si no está debidamente

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

(2)Siempre descargue el ánodo del tubo de la imagen a tierra

para evitar el riesgo de choque eléctrico antes de remover la tapa del ánodo.

(3)Descargue completamente el alto potencial del tubo de

imagen antes de manipularlo. El tubo de la imagen es de alto vacío y, si se rompe, los fragmentos de vidrio salen despedidos violentamente.

2. Si se quemara algún fusible de este receptor de televisión, reemplácelo con otro especificado en la lista de partes.

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

4. Cuando reemplace un resistencia de vataje (resistor de película de óxido metálico) en el Tablero o Plaqueta de circuitos, mantenga la resistencia a un mínimo de 10mm de distancia.

5. Mantenga los alambres lejos de componentes de alto voltaje o de alta temperatura.

6. Este receptor de televisión debe conectarse a una fuente de 100 a 240 V AC.

7. Antes de devolver este aparato al cliente, haga una verificación de fuga de corriente sobre las partes metálicas del 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 de choque eléctrico. Enchufe el cordón directamente al tomacorriente de la línea de AC 100-240V.

No utilice una línea aislada de transformador durante esta verificación. Use un voltímetro de 1000 Ohmios por voltio de sensibilidad o más, en la forma que se describe a continuación. Cuando la unidad está ya conectada a la AC, pulse el conmutador primero poniéndolo en "ON" (encendiendo) y luego en "OFF" (apagando), mida desde un punto de tierra conocido, tal como una (cañería de metal, una manija metálica, una tubería etc.) a todas las partes metálicas expuestas del receptor de televisión (antenas, manijas de metal, gabinetes de metal, cubiertas de metal, palancas de control etc.,) especialmente cualquiera de las partes metálicas expuestas que puedan ofrecer un camino hacia el chasis. Ninguna medición de corriente eléctrica debe exceder de 0.5 miliamperios. Repita la prueba cambiando la posición del enchufe en el tomacorriente. Cualquier medición que no esté dentro de los límites especificados aquí representan un riesgo potencial de choque eléctrico que debe ser eliminado antes de devolver el equipo al cliente.

of the Color Temperature

(1) Purpose: Adjust the color temperature to reduce the

deviation of the module color temperature.

(2) Principle : To adjust the white balance without the

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

(3) Adjustment mode: Two modes of Cool, Warm and Medium

9-2. Required Equipment

(1) Remote controller for adjustment (2) Color Analyzer : CA-100+ or CA-210 or same product

- PLASMA TV(ch : 10)

(3) Auto W/B adjustment instrument(only for Auto adjustment)

- Do the white balance adjustment under the 10LUX

[ Notice: When using the Color Analyzer with PDP,

recommend the CA-100 more than CA-210. If CA-100 can not available, it is also good to use the CA-210.

(4) PC (for communication through RGB) (5) Pattern Generator (MSPG-925FA etc.)

-Before white balance, press the ADJ key and select third row like (Fig. 5)

-To enter White-balance mode, Enter Password Number “0 0 0 0” and select third row.

used in the calibrated ch by CS-1000(PDP : CH10)

2) Adjustment remocon

- For manual adjustment, it is also possible by the following

sequence. Operate the zero-calibration of the CA-100+ or CA-210, then stick sensor to the module when adjusting.

(1) Select white pattern of heat-run by pressing “POWER ON”

key on remote control for adjustment then operate heat run longer than 5 minutes. (recommend) (If not executed this step, the condition for W/B will be different)

(2) Changing to the AV mode by remote control.(Push front-

AV) (3) Input external pattern(85% white pattern). (4) Stick sensor to center of the screen and select each items

(Red/Green/Blue Gain and Offset) using

D/E(CH +/-) key

on R/C.. (5) Adjust R/ G/ B Gain using

F/G(VOL +/-) key on R/C.

(6) Adjust three modes of Cool, Medium(Vivid) and Warm as

below figure.

(Fix the one of R/G/B and change the others)

- Push the “VOL + “ key : Cool, Medium, Warm

[

Refer to the below case to know what value is fixed.

[CASE] First adjust the coordinate much away from the target value(x, y).

1. x, y > target

1) Decrease the R, G.

2. x, y < target

1) First decrease the B gain,

2) Decrease the one of the others.

- In case of decreasing the x, decreasing the R : fix G

- In case of decreasing the y , decreasing the G : fix R

3. x > target , y < target

1) First decrease B, so make y a little more than the target.

2) Adjust x value by decreasing the R

4. x < target , y > target

1) First decrease B, so make x a little more than the target.

2) Adjust x value by decreasing the G

(7) When adjustment is completed, Exit adjustment mode

using EXIT key on R/C.

9-5. Connecting diagram of Equipment for

Measuring

(For Automatic Adjustment)

(method 1, using IIC, You connect RGB Cable)

(1) Enter the adjustment mode of the white balance

- Enter the white balance adjustment mode at the same time heat-run mode when pushing the power on by power only key

- Maintain the white balance adjustment mode with same condition of Heat-run

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

(2) Release the white balance adjustment mode

- Release the adjust mode after AC off/on or std-by off/on in status of finishing the Hear-run mode

- push the “power on” key(IIC Mode) on Adjust remotecontroller.

- Release the Adjust mode when receiving the aging off command(F3 00 00) from adjustment equipment)

(3) Enter the adjust mode of white balance

- Enter the white balance adjustment mode with aging command(F3, 00, FF)

O Color Temperature & Color Coordinates Setting

- When adjusting the Color Temperature, Color Analyzer CA210(Matrix should be corrected through CH10 of CS-1000) should be used. When CA-210 have used, it don’t need to fit the CH10.

- Adjust the Color Temperature based below adjustment color coordinates.
