iMac wont power up, replaced power supply. Bad logic board?
Hello, I have an iMac A1418 . When I press the power button I get no chime, no hard drive spinning up, no fans going. I suspected faulty power supply so I ordered one and replaced it.
I have not plugged the screen in yet, just all the new power supply cables to test but I am still not getting any response from the computer. Things I have tried below.
1. Turned of machine and unplugged all cables. plugged just the power cable back in and tried turning on, nothing.
2. Tried using a different power cable
3. Tried using a different outlet.
4. Replaced with new power supply.
I was informed that their should be diagnostic led's that are next to the ram slots? Would this then mean that I need to disconnect the logicboard to access behind it where the ram is so I can view the diagnostic led ?
again the computer does absolutely nothing when attempting to power on. No chime, no fans, hard-drive does not spin up nothing.
Any help is greatly appreciated.

No te LED are not next to the ram. You see the LED without disconnecting the logic board. They are right in front of you. A bit lower then the RAM. (see pics in my question)
