Hi, I was wondering if anyone was familiar with an "F76" error with the Panasonic Q. The problem is that when I turn on the machine it starts to boot and then it just turns off, and the LCD display says "F76." If I try to open the tray it will start to open but ends up turning off before the entire tray has been ejected from the cube. I have had this thing for 3 years and have been using it continuously...and it totally worked fine just yesterday, so I am kind of confused as to what this might be. Any help would be greatly appreciated.
