How to confirm it is logic board of PSU issue?

crwdns2934249:0crwdne2934249:0:

My iMac doesn't turn on at all, did the followings:

# removed the screen panel completely.
# Get power cable connected.
# No diagnostic indicators on logic board is light up.

Is there a way to detect if something wrong with the PSU or logic board in this case?

Thanks,
