iMac Intel 24" EMC 2134 and 2211 Diagnostic LED's: 0 단계, 이미지 1개 중 1개

  • To observe the LED's you need to apply power to the iMac with the front bezel off. Please ensure you don't touch any part of the iMac or the exposed circuit boards while you have power connected.

  • Locate the Diagnostic LED's between the RAM slots and the SATA connector.

  • The LED's are numbered 1-4 from left to right. You may need to move the SATA cable to get a clear view of the LED's.

  • If you are using this guide for iMac Intel 20" EMC 2210 and 2133 the LED's are located above the SATA connector and not as visible.

  • LED 1 - Indicates that the trickle voltage from the power supply is detected by the main logic board. This LED will remain ON while the iMac is connected to the AC power. The LED will remain on even when the computer has been shut down or put to sleep. The LED will turn off only if the AC power is disconnected or the power supply is faulty.

  • LED 2 - Indicates that the main logic board has detected proper power from the power supply when the computer is turned on. This LED will be ON when the computer is turned on and the power supply is working correctly.

  • LED 3 - Indicates that the computer and the video card are communicating. This LED will be ON when the computer is communicating properly with the video card. If LEDs 1 and 2 are ON and you heard the startup sound, but LED 3 is OFF, then the video card might be installed incorrectly or need replacement.

  • LED 4 - Indicates that the computer and the LCD display panel are communicating. This LED will be ON when the computer is turned on and video signal is being generated. If the LED is ON and there is no image on the LCD display panel, the LCD display panel or inverter might be installed incorrectly or need replacement.

Para observar los LED, debes encender el iMac con el bisel frontal apagado. Asegúrate de no tocar ninguna parte de la iMac o las placas de circuito expuestas mientras tengas la alimentación conectada.

Localiza los LED de diagnóstico entre las ranuras de RAM y el conector SATA.

Los LED están numerados del 1 al 4 de izquierda a derecha. Es posible que debas mover el cable SATA para obtener una vista clara de los LED.

Si estás utilizando esta guía para iMac Intel 20" EMC 2210 y 2133, los LED están ubicados sobre el conector SATA y no son tan visibles.

LED 1: indica que la placa lógica principal detecta el voltaje lento de la fuente de alimentación. Este LED estará ENCENDIDO mientras el iMac esté conectado a la CA. El LED estará encendido incluso cuando la pc se apague o se suspenda. El LED se apagará solo si la CA está desconectada o si la fuente de alimentación está defectuosa.

LED 2: indica que la placa lógica principal ha detectado la alimentación adecuada de la fuente de alimentación cuando se enciende la computadora. Este LED estará ENCENDIDO cuando la computadora esté encendida y la fuente de alimentación funcione correctamente.

LED 3: indica que la pc y la tarjeta de video se están comunicando. Este LED estará ENCENDIDO si la computadora se esté comunicando correctamente con la tarjeta de video. Si los LED 1 y 2 están ENCENDIDOS y escuchaste el sonido de inicio, pero el LED 3 está APAGADO, es posible que la tarjeta de video esté mal instalada o necesite reemplazo.

LED 4: indica que la pc y el panel LCD se están comunicando. Este LED estará ENCENDIDO cuando la pc esté encendida y se esté generando la señal de video. Si el LED está ENCENDIDO y no hay imagen en el panel de la pantalla LCD, es posible que el panel de la pantalla LCD o el inversor estén instalados incorrectamente o necesiten reemplazo.
