I failed to self repair my PC monitor. Help?

Testo:

One of my monitors, a AOC 2330Fz, recently stopped showing anything on screen, although it would power on and my PC would recognize it as a working display. After some research, and some examination, I learned that the backlight had stopped working , but the LCD was still functional.
 
Reading further into it, the probable cause was a bad capacitor(s) on the power supply board, so I opened up the monitor and found one visibly damaged capacitor. I ordered some 1000uf 25v Electrolitic capacitors that I thought would be suitable replacements for the bad 1000uf 25v Electrolitic capactitor that I found on the board. [https://www.amazon.com/gp/product/B06WGPNM19|These are the ones I ordered.] When I received these capacitors, I noticed that they are a little smaller than the bad capacitor, but I went ahead and replaced it anyway.
 
Now, my monitor seems to have a working backlight, but an entirely new problem. When I plug in the power to the monitor, it tries to power up. It lights up for less than a second and then there is a very faint click sound that comes from the power supply board and the monitor shuts off, briefly, then tries to power on again and continues to cycle this way.
 
'''TLDR''' - I replaced a capacitor on my monitors power supply board in order to fix the backlight. Now my monitor tries to power on, shuts off in less than a second, tries to power on again, and continues in the pattern.
 
Did I do something wrong in my repair? What might be causing this new problem?
 
Thanks!
