I have a sharp xv-z3100. On stand-by it shows solid green for power and red for lamp. I unplugged and replugged as manual suggested and it turned on correctly once, but now all uses of projector result in green power red lamp again. When I turn on projector the menu is reset to default (e.g. upside down view, all default colors, new keystones, and red screen) and no matter what input I select it will not display the content. But the menu is displayed...
