iMac wont power up, have tried everythingreplaced power supply. Bad logic board?

テキスト:

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.
