Depends entirely on what you mean by "takes time". These projectors require a few minutes to reach full brightness, and many models even activate an LCD shutter to black out the image until the lamp has reached reasonable brightness.
If you mean it takes several minutes to produce any picture at all, it may just be time to replace the lamp, as it may not be striking (starting the lamp) correctly due to a fault in the lamp starter circuit or the lamp itself. In the absence of a detailed fault description, my best guess is that it's most probably a tired lamp :o)
