Sorry if this is the wrong spot to post this, I don’t see anywhere else to put it.

I decided to clean my keyboard today, and I’m not sure if it’s mechanical or not, it might be somewhere in between. It’s a Medion from the early 2000’s. Anyways, I unplugged it, unscrewed the casing, and took it apart to clean the keys and underneath. I made sure to not touch any electronics, since half of he keyboard houses electronics and the other half (the keys) is all plastic. I cleaned it well, put it together, and when I plug it in, it doesn’t work anymore. The lights for caps lock and such blink and that’s it, so I know it gets power. Any help? (No keys work at all)
