No response when power button is pressed.
Hi guys,
I have recently acquired a 2017 21.5” iMac which is dead. Only 1 of the diagnostic LEDs are on, so I changed the PSU and it's still the same. I have disconnected all (but the PSU connections, tried an SMC reset, drained all the power and took the Logic Board out and gave it a visual inspection but now I've ran out of ideas. I assume it's likely a board level repair but I was just wondering if any of you gurus on here have any ideas, or obvious solutions?
Any help would be greatly appreciated.
Thanks,
Andy.
Is this a good question?

Have you tried plugging it into an external display?

No, it doesn't boot at all, no fans spinning or LED lights past the first one, so it didn't cross my mind.

@andyc7117 Can you check for voltage from the power supply?
