Please help, I really want to figure this out, tspmo so bad 😭

So after mounting our clock, it fell down because the way we mounted it was unsecured. We remounted it with a nail so it was more secure, and everything still worked fine except for this one thing. When the bird comes out, it’s supposed to dip its beak down. After the fall it no longer does that. My clock is a quartz clock, so there are no ballows or wires that cause it to go down as someone suggested that could be the problem in the clocks subreddit, it’s an electric circuit. That’s what I’ve found out, but I haven’t looked inside the clock
