There must be service reps in Wisconsin - here I am in the UK and I used the internet (it operates across national boundaries) to find this for you...

Give them a call - they sell Pinnacle Laminators so they will know who you can call on for help.
The on/off switch on your machine may indeed be broken but I would suspect an issue with the machine's power supply.
Have you checked the circuit breaker?
Good Luck...
