Warranty on Cameras 1year parts and labor


There is no response from the camera while pressing any buttons.
The LCD screen is frozen or the camera is hanged.
Remove and re-install the battery or batteries to reset the camera. Your valuable data stored in the camera will not be lost.

I hope some of this helps, if not above is the contact number for Polaroid tech support. You camera seems to be still covered under warranty.
Good Luck
