Apple iii repair help?

Hey guys,

So I recently got an apple iii from Jenn, it was working and then the cap blew, she gave me the option to fix it myself or she could fix it. I recapped it and turned it on and had no signs of life. I put the power cord on the power supply backwards...

Now when I turn on the computer I get a bunch of dots, and then it switches to a screen pattern of 5v + and - I'll attach photos below... Any ideas?
I'm thinking it was either from me or something is not reading right because fedex dropped and damaged the computer.

Thanks
Sam
