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"

INSTRUCCIONES DE SEGURIDAD 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. La lectura no debe (READING SHOULD exceder 0.5mA NO T BEde ABO VE 0.5mA) LEAKAGE Probador CURRENT de fuga de corriente TESTER

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.

INSTRUCCIONES DE AJUSTE 1. Application Range This spec. sheet is applied to all of the PU84A chassis.

2. Specification (1) Because this is not a hot chassis, it is not necessary to use an isolation transformer. However, the use of isolation transformer will help protect test instrument. (2) Adjustment must be done in the correct order. (3) The adjustment must be performed in the circumstance of 25±5cC of temperature and 65±10% of relative humidity if there is no specific designation. (4) The input voltage of the receiver must keep 100~240V, 50/60Hz. Caution : 42PG20-UA must keep 100 ~ 120V, 50/60Hz.

(4) Click “Read” tab, and then load download file(XXXX.bin) by clicking “Read”

(5) The receiver must be operated for about 15 minutes prior to the adjustment. After RGB Full White in HEAT-RUN Mode, the receiver must be operated prior to the adjustment. O Enter into HEAT-RUN MODE (1) Press the POWER ON KEY on R/C for adjustment. (2) Press the ADJ KEY on R/C and enter EZ ADJUST Select “4. White Pattern” by using D/E(CH +/-) and press ENTER(V) Select “White” by using F / G (VOL +/-) and press ENTER(V) O

(5) Click “Auto” tab and set as below (6) Click “Run”. (7) After downloading, check “OK” message.

- Set is activated HEAT run without signal generator in this mode. - Single color pattern ( RED / BLUE / GREEN ) of HEAT RUN MODE uses to check panel. Caution: If you turn on a still screen more than 20 minutes (Especially digital pattern, cross hatch pattern), an after image may be occur in the black level part of the screen.

3. Download (1) Execute ISP program “Mstar ISP Utility” and then click “Config” tab. (2) Set as below, and then click “Auto Detect” and check “OK” message If display “Error”, Check connect computer, jig, and set. (3) Click “Connect” tab. If display “Can’t” , Check connect computer, jig, and set.

7. Adjustment of White Balance

(1) Adjust in the place where the influx of light like floodlight around is blocked. (illumination is less than 10ux). (2) In case of PDP: Measure and adjust after sticking the Color Analyzer (CA-100+, CA210) to the side of the module.

Caution: Press the POWER ON KEY on R/C before W/B adjustment.

7-1. Test Equipment - Color Analyzer (CS-1000, CA-100+(CH.10), CA-210(CH.10))

In case of LCD: Adhere closely the Color Analyzer ( CA210 ) to the module less than 10cm distance, keep it with the surface of the Module and Color Analyzer’s Prove vertically.(80~100°).

[ Please adjust CA-100+ / CA-210 by CS-1000 before measuring --> You should use Channel 10 which is Matrix compensated (White, Red, Green, Blue revised) by CS-1000 and adjust in accordance with White balance adjustment coordinate.

(3) Aging time 1) After aging start, keep the power on (no suspension of power supply) and heat-run over 15 minutes. 2) In case of PDP, keep white pattern using inside pattern. 3) In case of LCD, using ’no signal’ or ‘full white pattern’ or the others, check the back light on.
