All In One Computer Wont Start

[Thewavinace]

I am having a problem with my all in one computer as it won't boot up. I have opened up the computer to check for any wires that have been disconnected and such but everything looks in-tact. I have also tried see if the power cord works by plugging it in to other devices compatible with it and there seems to be no problems with the power cord itself.

One thing I have noticed is that when I plug in the computer, no light id shown. When it used to work, it would display light that would indicate it's on and recovering power.

Any help would be widly appreciated 👍.
