Generally, BenQ projectors produce clear and colorful images. But at times, you’ll notice a yellow tint on your screen as you binge on your favorite shows, movies, or videos. This can be so annoying and may end up ruining your viewing experience.
Keep reading as we take a look at why BenQ projectors display a yellow tint and how you can solve it.
Why do BenQ projectors show a yellow tint?
The yellow tint on your screen is likely to have been caused by one of the following:
Dirty projector screen
The most common cause of a yellow tint is a dirty projector screen. If you regularly set up your BenQ projector outdoors as well as your screen, there’s a chance dust and other debris have settled on your screen. These will interfere with the black levels and color arrangement resulting in a yellow tint.
Cleaning your screen should solve this problem. You will need:
- One pair of gloves
- Microfiber cloth
- Mild detergent
Follow the steps below to get rid of the contaminants on your screen:
- Wear gloves. Their purpose is to prevent any oil or grease on your fingerprints from getting into contact with the screen.
- Add the mild detergent to the water
- Soak the microfiber cloth in a mixture of water and mild detergent
- Gently wipe the projector screen to avoid damaging its material
- Find a contaminant-free place to lay out the screen to dry
Dirty or old projector lamp
Projector lamps are responsible for producing the light that is processed and enlarged to create the images that are shone on the screen. Dust, smoke, and debris may have accumulated on its surface over time leading to a yellow tint being displayed.
Gently cleaning it with a soaked microfiber cloth should remove the discoloration if that’s the issue.
Another cause may be that the lamp is old and requires to be replaced. As I’m sure you know, bulbs tend to become deemed and lose color accuracy as they near the end of their life. To replace it, you’ll need:
- A pair of gloves
- A new lamp from a reputable business
- A screwdriver
Then follow the steps below:
- Turn off your BenQ projector and unplug the power cord for safety. Allow it at least 30 minutes to cool down before proceeding.
- Loosen the screws holding the lamp cover in place using the screwdriver and remove it. Be sure to place the screws somewhere you can recall.
- Unscrew the fasteners holding the old lamp in position and remove it from the socket
- Fit your new lamp into the socket and secure it using the fasteners you had unscrewed earlier
- Secure the lamp cover using the screws you had removed
- Turn on the projector
Faulty cables are another cause of yellow tint in BenQ projectors. They are critical to any kind of projection because they link the source and the projector. A yellow tint is typically due to a bent, broken, or rusted blue pin in the HDMI or VGA cable.
The simplest way to solve this issue is to straighten out the crooked pin. And if that doesn’t work, get a new set of HDMI or VGA cables.
Polarizers are critical when it comes to the processing of light from a source in the projector. They help with color filtering to ensure you get accurate colors in your images. As you can guess, when they are defective, there will be a discoloration problem, in this case, a yellow tint.
The only solution is to replace the malfunctioned polarizer. To do that, contact a talented technician or get in touch with BenQ customer support for further guidance.
