Toy Clock partially working

Toy Clock partially working

We have an Animated Haunted Halloween Clock we bought at Grandin Road (you can see the video of how it works on Youtube). The 2 issues are: the eyes no longer light up, and the ghoul no longer pops out and moves his mouth. We opened the back and there is a tiny pcb and needless to say - it’s greek to us. I can send pics. Please help. Thank you. Stacey
