Polaroid is no longer the company it used to be.

Polaroid was sold, several years ago, to a company that finds foreign business partners for American companies.

Polaroid is now a marketing company.
Which means they import things into the USA and sells them.
Most of the items are made in China.

If something breaks, they don't repair it, they replace it.
So there are probably not any parts available.

Check and see if the camera is still under warranty.
If it is, call Polaroid and get it replaced.
If it is not, toss it in the trash and buy something better.
