Your projector’s old or burned-out bulb will probably make the image appear yellowish. The reason for this is that the faulty bulb is no longer emitting the proper spectrum of light.

Quick Fix

The bulb needs to be changed because that is the simplest solution. Make sure, though, that you are using the right kind of bulb for your projector first.

This information is available in the projector’s handbook or online at the maker’s website.

However, if you don’t know what you’re doing, opening up a projector can be extremely dangerous.

Take the projector to a service provider and seek assistance if you don’t feel confident opening it up yourself.

Examine your wires


Let’s say you followed the instructions but the accuracy of the colors was the same. Your input signal connection cord can be the problem in that instance.

Quick Fix

To begin with, make sure your connectors are secure and undamaged. Image problems are brought on by faulty connectors or a loose VGA connection.

Defective optical components

Polarisers, which are found within LCD projectors, regulate the colors as they travel through the LCD screens.

These panels may eventually stop consistently and correctly passing colors.

Polarizers typically degrade gradually, first showing discoloration in isolated regions before eventually covering the entire screen.

Quick Fix

Sometimes the little circular disc will stop spinning due to the buildup of dirt and dust. The color wheel will need to be changed in this situation.

Projection Software

The image can appear yellow if there is a problem with the projection software.

Quick Fix

You will need to update or reinstall the software in this situation.

Image is Projected on a Yellow Surface

The projected picture will also seem yellow on the screen if it is displayed against a yellow background.

Quick Fix

The simplest course of action in this situation is to relocate the projector or simply display the image on a white surface.

How can I make my projector’s color better?

  1. Something is likely preventing the light from reaching the entire surface. To check if it helps, try moving anything that might be in front of it or to your side. This will at least let light in and let you see the problem’s root cause more clearly.
  2. The light won’t be able to adequately shine through if you are too far away, creating a shadow. If it is too low to the ground, this may also be of assistance.
  3. To get rid of any shadows that show up on your screen, make sure the focus is tightened. If that doesn’t work, there might be a problem with the projector lens.
  4. This feature is not available on all projectors, although some do. Fix any shadows that occur on your projector screens by adjusting the image quality setting, if the projector has one. By doing this, you’ll be able to project your image onto the screen with accuracy.
  5. A shadow may appear on the screen depending on how close or how far you are from it. Make sure your projector is positioned properly by making the necessary adjustments.
  6. Shadows from your projector may be visible on the screen since you recently changed your bulbs. To fix the issue, confirm that both are placed correctly and are not missing.

Safety Tips

Here are some safety guidelines for repairing a yellow projector.

  • The projector should be turned off and unplugged from the wall.
  • To clean the projector’s lens, use a dry towel. If that doesn’t work, try cleaning it with a can of compressed air.
  • If neither of those approaches works, you might need to change the projector’s light.
  • When doing so, be sure to adhere to the manufacturer’s guidelines
