Why does my iMac G5 not power up after logic board exchange?

Texte:

Hello

I exchanged my Logic Board in this computer now it will not start up.

The old board had a couple bad capacitors and the computer would sometimes start and run for awhile before freezing up.

I have checked the LED's and the # 1 light is on when plugged in.

When I hit the power button the # 2 light comes on, the chime sounds and then the # 4 light comes on, red color, and the computer powers down. The # 2 light goes out and the # 4 light stays on.

I can get the # 4 light to go out by bumping the power button but when I try to start up again the same thing happens.

Checked my power supply and it has a small burnt spot in the upper left part of the lower right quadrant and a white foaming looking substance on the board. Not sure if this is why it is not powering up because of the # 4 light coming on.

In all the research I have done I have not come across this issue so not sure what is going on.

So my questions are;

Why is the # 4 light coming on while the computer is starting up?

Is this why it is shutting down?

What is causing this issue and how do I fix it?

Or is it all tied to the power supply?

Any advice would be very much appreciated and thank you in advance.
