No power, only one diag light is on

Hey everyone,

I recently rebuilt a 2013 27” iMac and upon reassembly the iMac shows no signs of power, with the only diagnostic light being the one indicating AC power is present. Any ideas what I should troubleshoot from here?

Thanks

What did you do? Swap out the drives or CPU?

@danj Swapped out CPU.

I’m suspecting the CPU chip is not fully seated and you may have a few bent pins. The RAM cage and the heavy springs makes replacing the CPU harder than one would expect.
