Won't boot - replaced power supply - now what?

iMac 21.5" EMC 2389 Model 1311

Hi

I was given the above iMac to fix following another person's diagnosis of a bad power supply and a PRAM battery needing replacing. Done both those things and still no joy. AC power all the way from the wall socket to the main line into the new power supply (measured at the solder points on the PC board). Not sure where the LED lights should be for this model, so I took some pictures of what I think are the right ones. If so, no LEDs illuminated.

Looking for suggestions as what to check next?

just to orient you

Thanks

Greg

If there are no LED's illuminated and you've replaced the power supply, either DC in or logic board I would imagine. If you have trickle power to the board, LED #1 will illuminate.

Check this question for the location of the diagnostic LEDs and what they mean: Where are the diagnostic led's on this model's logic board

Where did the new power supply come from?

You images need to be attached to the question.
