power supply, or ...?

A borrowed machine was being placed in a new environment for the first time.

The power cable was not fully seated into the power supply on the back of
the machine, and when power was supplied, there was a flash and a pop. Power
was removed from that machine, the cable was checked for damage, the power
inlet appeared normal (although there was the distinct electrical odor for a
while).

The power supply was removed and examined, with no visible signs of damage
or gross electrical odor. A small apparent fuse within the ILSSAN ISP 120S
Rev. C-2 appeared normal, as the small copper strip was continuous and no
discoloration of the glass wall was evident.

After re-assembly, the power indication light on the front of the box does
not light when the main switch is pressed on, nor is there any other type of
system activity.

The question is, please: Is it likely that a simple power supply replacement
will solve the problem, or is it possible that the main switch has been
damaged? I can't find a pinout diagram for the power supply, so don't know
which connectors to test for continuity to the main switch etc. where it
connects to the backplane

A replacement power supply is about US $25, but I wanted to check with the
wealth of knowledge here about what to do or consider before possibly
wasting the money. I'm well aware of the general eMachine opinions and agree
with them, but this box is borrowed.

Thank you.
