Why does your projector have a yellow tint?

Answer 1

Computers use three signals to create a color image. Red, green and blue colors are mixed to create all colors on the screen. If one of the three colors is missing, a color cast will be seen. The green and yellow tints indicate that the blue signal is missing. White will therefore be a mix of red and green rather than a mix of all three colors. The color displayed will be yellow rather than white. Some projectors also use the same connectors for both RGB and component signals. Component signals also use three wires but the color is encoded differently. If the projector is looking for a component signal and actually receiving an RGB signal, color distortions will result. Check the input set up on the projector to see if it is set to component instead of RGB or VGA settings. Often, the problem can be tracked down to the interconnect between the computer and the display. VGA connectors and the cable are liable to fail after a period of time because of the delicate nature of the connecting pins or the cable itself. The first step is to replace the cable and see if the problem is fixed. If not, then the problem may well be within the display card of the computer or the receiver circuitry in the projector. If possible, use a known good computer display and cable to see if red green and blue are being output from the computer. If they are, then the input circuitry in the projector is suspect. If the fault persists, it points to a fault in the computer itself.
