Common Projector Problems and Solutions
ProblemPossible Solution
Projector is not turning on when pushing the power button.
  • Make sure the outlet in which the projector is connected has power.
  • Some projectors also have "indicator" or "status" LED lights on the control panel. If this light is on or flashing please refer to your owner's manual or manufacturer's website for solutions and explanations.
Projector is not getting a signal or is not projecting the computer picture.
  • Check to make sure you are on the current input. Most projectors have multiple inputs (I.E., Computer 1, Computer 2, DVD, etc.), toggle through the inputs by pushing the input button on the top of the projector.
  • If that does not resolve the problem, check the video cable otherwise known as the VGA cable (Click here). Make sure the cable is connected to the computer's VGA port and the projector's VGA port (Click here).
  • If you are using a laptop, you may have to hit the FN key and a function button to get the picture to project from the projector. First locate the function key at the top of your keypad that reads LCD, CRT or it may have an icon that resembles a computer monitor. By pressing the FN key and the corresponding function key you will be able to obtain the image from the projector only or both the projector and the laptop screen.
Projector is only projecting a partial image or part of the image is cut off.
  • This is normally caused by the computer's resolution not being completely compatible with the projector's resolution.
  • You will need to adjust your computer's resolution to match the projector. (The projector's resolution can be found in the "specifications" page of the projector owner's manual or website).
  • To change your computer's resolution setting, right click the desktop and click on properties. Click on settings and change the resolution to a lower resolution by moving the slide cursor to the left (Click here)
The Projector powers on, but the LED light on the top is blinking.
  • While every projector is different, and you will have to consult each projector's manufacturer's website for specific information, a blinking LED light usually points to an exhausted projector lamp.
  • Average lamp hours range from 1,500 to 2,000 hours. Most projectors use a lamp hour counter to track the number of hours of lamp use. The projector will usually post a message on screen when the lamp is nearing the end of its life expectancy.
  • Contact your technology coordinator for a lamp replacement. Be sure to provide the tech coordinator with the make and model number of your project.
