Troubleshooting a Dell projector starts with the connector port.


Dell projectors are made with digital circuits to handle various color palettes ranging from XGA to SVGA graphics. However, they can have problems with flashing colors and a blank display. Start your troubleshooting process between the connector on the projector and the incoming signal from the laptop or computer.


Problem


Inspect is the connector port, which is usually a 9-pin configuration. If any of the pins are crooked or bent, this could cause the projector to flash different colors. Each pin represents a color mode that collectively creates the color palette for the projector. Another source of problems includes a defective bulb within the projector.


Solution


If the problem is located within the 9-pin connector, the pins within the connector can be straighten with tweezer-nose pliers. Use extreme when straightening a connector pin because it could easily dislodge or snap. The projector can also be taken to a Dell technician for troubleshooting and repair.


Expert Insight


Other items to look for are the compatibility between the projector and the source, which is usually a laptop or computer. If the computer displays images in a graphics mode that is incompatible with the projector, it can cause color problems, inadequate display problems and a flashing color.
