For some reason our pp is working but you can not change any of the settings. None of the buttons work. Has anyone had this problem before?

I've had it with my pp.The problem was the flatcable in the display the + was broken.I could not repair it so i bought a new one.

Hmmmm... call Perfect Pass.... or maybe they wont know... or hmmm... maybe they will... after all.... They are the manufacturer...
