Hi, if your LCD projector turns on and projects light with sound but not the picture on your computer screen, first make sure the projector is plugged into your computer. If it is, check your computer display settings. Go to "Control Panel" and "Settings" or "Windows Setup." Select "Display." Make sure it's set to appear on your laptop screen and the the projector screen. Most laptops have a "Fn" key dedicated to changing the output display setting.
If your projector turns on but emits no light or picture, replace the projector's bulb, often called the lamp. Most have a life of between 2,000 and 6,000 hours. Your projector may warn you when the lamp life is about to expire, although some models simply stop working when the lamp needs replacing.
Thank you.
