Why my iMac does not Turn ON?

I have been using my imac for a year.

Yesterday I tried to turn on the machine without any success.

I only hear a short noise if I have my ear in the side of the optical drive and after that a fan working (low noise). Nothing else after that, the screen remains off.

There is only one green LED at the lower part of the iMac.

The only way to turn off the fan is by forcing a shut down with the power button.

The aforementioned LED remains off after shutdown.

I removed the power cable, check the source voltage, tried another outlet without any luck.

Help please. Thanks

Do you know where I can find the Power supply and the Part Number? (I am assuming that the logic control board is OK)

Thanks for your help.:-)

Hi, Here is a link to another answer that explains the LEDs. Based on what I see I think you may have a power supply problem. Good luck.
