Hello leaders,
Motherboard number: 820-3588

I have a problem with an Imac A1418, she turns on when she wants, I have replaced the original power supply and it does the same.
The led diagnosis:
Led # 1 turns on and when I press the power button it blinks 1 time and led # 1 stays on.

I recorded this video for you:

I have tried turning it on without ram and it does the same.
I replaced the battery on the board and I have the same result.

Any bad resistance?
I really don't know, I'm starting with electronics, a push I need from you wise men.

Blessings.

Thank you, I am going to request that now, it will take me at least 19 days to receive those pieces, should I take into account any other matter?
