I have a ceiling mounted Infocus SP4800 that I have had for a couple years now and it has worked great. Today I turned it on and it would not display my HDTV signal plugged into the vga (computer) input on the projector. I tried a DVD player in progressive scan mode (that has always worked before) and that didn't work either.

I next tried my playstation 2 on Video Input in progressive scan mode (normally projects 480i). The image was doubled horizontally, like if you connect a progressive scan image to a non-progressive scan display. I took the PS2 off of progressive scan and the image displayed OK.

What could have happened to make my progressive scan sources suddenly stop working? I tried a factory reset and upgraded my firmware to the latest but to no avail. Anyone have suggestions or options?

Thanks!
