Why Is My Projector Showing Yellowed Images?
Projector discoloration often has four common culprits:
- A discolored projector screen
- An old and dirty projector lamp
- Faulty wirings
- Defective polarizers
To determine which of the following situations are causing the issue, you’ll have to examine each component closely.
A discolored projector screen
There is a ton of environmental factors that can affect the color of a projector screen. The most common being dust and debris. Dust can interrupt your screen’s black levels and color composition, causing images to look discolored.
An old and dirty projector lamp
Much like every other item, projector lamps have an expiration date. When your projector lamp is nearing this date, it can affect how it renders color. The typical projector lamp lasts about 2,000 hours, depending on its capabilities.
Smoke, dust, and debris can also accumulate on your projector lamp over time, leading to image discoloration.
Your projector’s cables and wires connect your source to your projector. If a single component on these connectors is out of place or faulty, it can cause color discoloration. Particularly, if your projector shows all yellow images, it may be because the blue pin on your cable or wire is bent, rusted, or broken.
Polarizers are responsible for manipulating the colors that pass through the LCD panels on a projector’s optical components. After some time, these components eventually begin to fail, causing discolored images on-screen.
How to Fix BenQ Projector Discoloration Issues
There’s no need to hire a color expert to address your BenQ projector discoloration issues. The tips we’re giving you below will help you fix your BenQ projector and take your viewing experience to the next level.
Cleaning the projector screen
Cleaning your projector screen of dirt and debris is very simple. Most screens come with a cleaning manual out of the box. However, there’s no need to worry if you don’t have one.
Here are the materials and equipment you’ll need:
- A pair of clean gloves
- Microfiber cloth (or any other lint-free cloth)
- Mild soap
The gloves will help prevent grease and oil from your fingerprints from sticking on the projector screen surface. Put them on before wiping your projector screen with the microfiber cloth that has been soaked in a solution of mild soap and water. Do this gently; absolutely NO RUBBING, or you risk destroying the projector screen material.
Once you’re done wiping down the entire surface, layout the projector screen to dry. Find a safe and clean place to avoid contracting more dust and dirt.
Replacing the projector lamp
This task can feel intimidating, especially for those with very little experience with tools. However, the process is very simple. Even beginners can do it.
Things you’ll need:
- A screwdriver
- A pair of clean gloves
- A new lamp/bulb
- A small container with separate compartments
Perform the following steps:
Step 1: Press the main power source on your BenQ projector to turn it off. Next, unplug the power cable from its outlet.
Note – Make sure to let your BenQ projector cool down for at least 45 minutes before proceeding to the next step.
Step 2: Take your screwdriver and loosen the screws below the BenQ projector lamp cover. Place the screws inside your small container to avoid losing them.
Step 3: Once you’ve got the cover off, loosen the bulb by unscrewing the fasteners. Take the bulb and screws. Discard the faulty lamp and place the screws in your small container, separating them from the others.
Step 4: Take your new bulb and fasten it into the socket. Use the correct screws; otherwise, it’ll cause other issues.
Step 5: Place the cover back on before turning your BenQ projector on to see the results.
If the discoloration remains the same, move on to the next solution.
Fixing/replacing faulty wirings
Crooked or busted pins are often what cause VGA and HDMI connectivity issues. If your BenQ projector shows yellow discoloration, this often means that the blue pin in your VGA or HDMI cable is faulty.
There are two ways you can solve this issue:
- By straightening the bent pin (which is harder said than done)
- By buying a set of VGA or HDMI cables
Loose-fitting VGA and HDMI cables can also cause color discoloration in the BenQ projector. To avoid this, ensure that all cables are properly secured in their appropriate ports.
Replacing the polarizer
Experts don’t normally recommend replacing projector polarizers unless your projector comes from a high-end manufacturer. However if you do get it replaced, make sure to call a professional to assist you.
The best way to find the right people is to get them from your projector’s manufacturer. These people are most likely to have the right parts for your projector type/model. Furthermore, they are less likely to commit mistakes that might damage the internal parts of your machine.
Are BenQ Projector Repairs Covered by Warranty?
BenQ offers a 2-year manufacturer warranty. You also get a 1-year/1,000 hours warranty for your projector lamp. Warranty longevity may vary depending on what region, state, or country you’re from.

Is It Worth It to Replace a Blown Projector Lamp?
It depends on the type of projector you have. If you got an expensive projector, then it makes more sense to replace a blown lamp to make up for the overhead costs of the projector. On the other hand, if you have a cheap projector, there wouldn’t be any point in replacing a blown lamp.
Projector lamps cost anywhere north of $300. BenQ sells them at $100 to $700, depending on the model.
There are several reasons why your BenQ projector shows signs of image discoloration. By pinpointing the cause of the issue, you’ll be able to find the best and most effective solution.
Above are just some of the simplest ways to fix BenQ projector discoloration issues. We hope that it helps you get rid of that annoying and unappealing yellow screen and lets you get back to watching vivid and crips TV shows and movies.
