    Toshiba TLP-670U. I was given this projector from my boss with the warning
    that it had stopped working for no good reason. I took it and it turns on,
    projects light and a quick colour change as its booting but then it only
    projects white light and I can't see any menus and doesn't seem to recieve
    input. The on and lamp lights are green and it seems to have no major
    errors. I was wondering if anyone could point me in the right direction on

    the monitor passthrough works as well, if I hook up my computer to the
    projector at 640x480x60hz then hook up my monitor to the projector my
    monitor works but still the projector only outputs white light

    Might not be a lot you can do. I'd start with the obvious, open it up and
    check all the outputs of the power supply. If they're labelled it's easy, if
    not, often you can guess more or less what they should be. It'd also be
    worth checking for loose connectors.

    most likely the LCD panel timing IC is wasted. common problem in those
