inappropriate iMac behavior
#1
my mum says her 2006 Intel 17" won't power up.
We haven't got to the nuance of reseating cables yet, nor the SMC reset.
The screen is black, the power button does nothing and the "night lite" is off.

I've been told that there are diagnostic LEDs inside the case that will give certain info, provided there's any power at all, I 'spect.

Does anyone know about said LEDs existence and what they might indicate?
Has anyone here ever dove in and swapped a PS in this beast, if need be.

I'm hoping for organic fix, butcha never know.

Not true. The aluminum series has them as well.

Ditto for the white intel iMacs...

To Access the LEDs:

1. Follow the take apart instructions to remove the RAM access door, front bezel, and lower EMI shield.

2. Locate the SO-DIMM slot and LVDS video connector. The three troubleshooting LEDs 1, 2, and 3 are located to the right of the LVDS cable connector, under a square of black tape. Peel back the tape to view the LEDs. Note that the LEDs are marked 1, 2, 3 from left to right. An additional front LED is located in an opening at the center of the right speaker.

LED #1
• Indicates that the trickle voltage from the power supply has been detected by the main logic board. This LED will remain ON whenever the iMac is connected to a working AC power source. 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 source 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 LCD display are communicating. This LED will be ON when the computer is turned on and video signal is being generated.

Front LED • Indicates that the computer has power but no video signal (e.g., the computer is starting up or the display has entered Sleep mode, turning off the video signal). This LED will pulse when the entire system has entered Energy Saver mode.
