2014 iMac Won't turn on and already replaced power supply

Testo:

So about a year ago my daughter hit the screen on my iMac. it instantly shut off never to power up again.

The 1st Diagnostic LED  on the logic board is lit but I can’t get the 2nd LED to turn on. I bought a replacement power supply and installed it with no change.

I also replaced the PRAM button battery and again no change. I verified the power button works using my multimeter and ohming it.

Not sure what else I can do beside a new logic board which at this point cost’s an outrageous amount for a 6 year old computer.

Any additional troubleshooting tips would be very appreciated!!
