No video or sound after replacing the power supply but fan works

I recently replaced my power supply and now I hear the fan power up but have no video or sounds.

What could be the problem now?

I tried the SMU reset but all it did was make the fan louder.

Is this a good question?

Look at the diagnostic lights on the logic board to get an idea of where to go next.

2 lights are on. I also see writing that says sys reset and SMU reset but saw no buttons as you listed in a previous post.

What next?
