Nizo S48 Movie camera

Well-maintained and clean camera.
After inserting the batteries, it can be controlled automatically via the switch.
But it won't turn on; you can hear a 'will' to start, but nothing happens.
Battery compartment is absolutely clean.
The battery indicator also works.
With user manual, lens hood, and camera bag.
The zipper pull on the camera bag is missing.
Otherwise no defects.
I’m including the film as well, but I can’t say to what extent it has been used or if at all.
