Today, I tried turning on my iMac A1058 computer and nothing happens (the indicator light won't even show. It was working perfectly fine the day before. I opened up the back panel and only LED 1 would light up. I don't see any corrosions and/or swelling on the 24 capacitors.

, sounds like a bad power supply. "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" Due to number LED 2 not turning on, you know that the first issue should be the power supply.
