@pvh, P Vanhemert, stefanie powers, If able to return it as defective for exchange/refund. There is probably an internal problem with the circuitry. If not returnable, 1st link below is a disassembly guide that can get you inside the zoomer dino to check for loose wires/connections/damaged components on board/etc. 2nd link is a troubleshooting link. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
