I really need some help. I have a mitsubishi 65" projection screen tv modle WS-65517. When i hit the device menu button the tv starts to run slow then it goes in to reset mode. I have tried to reset it manualy like the manual said to do and it still does the same thing. All of the other buttons work even the pip but i cant get the device menu to come up. Every thing is tight in back and all the wires are connected. How can i fix it? So my children can watch tv when they get up please help
