Why is my projector only showing a white light?
There could be a number of reasons why your projector is only displaying a white light. It could be due to a loose or faulty connection, a problem with the projector's bulb or color wheel, or an issue with the input source. Try checking the connections, replacing the bulb, or troubleshooting the input source to see if that resolves the issue.
How does a light bulb in a projector make all the colors?
The colors are not created by the bulb. Instead, some form of filter (film, slides, transparent writing surfaces, etc) is placed between the bulb and the screen (or whatever surface onto which the light is being projected). The filter blocks certain portions of light from passing through, and allows others. The result is that a lighted version of the filter's coloration pattern (picture, writing, etc) is visible on the screen or surface.
