Modern projectors are one of the best tools that any conference room can have. They also make for great additions to any living room or classroom looking to increase screen size. They are an affordable way to project images into large surfaces while still maintaining a clear, smooth, and sharp image. LCD screens have become an integral part of most projector’s optical assembly units since the 90s. In this article, we will show you how to properly clean and maintain the screen of an LCD projector.

LCD’s or Liquid Crystal Displays are the most common type of screen found on most electronic products. They are relatively affordable and very versatile, you can easily find LCD screens that are as small as a watch, or as big as a wall-mounted television set. They are used mostly in computer monitors, television displays, projectors, mobile phones, calculators, and even in military aircraft displays.

The screen works using the inherent properties of liquid crystals. The liquid crystals are usually held between two sets of transparent electrodes. When an electrical charge is passed between the electrodes, the molecules of the crystals can be manipulated predictably to form different images. Most LCD screens have internal control mechanisms that transform the signals coming from any given device into precise electrical inputs, these allow the screen to render any image we want.

If your screen gets dirty or damaged there is no need to panic. There are several solutions to keep an LCD screen well maintained and working properly. Let’s explore some of the main reasons the LCD projector screens get dirty or damaged.

There are multiple ways by which the LCD screen in your can stop functioning properly or decrease its picture quality. Maybe you can see a fractal of psychedelic colors when you project your image, or there is a visible line blocking the image that can’t be removed by simple cleaning. Let’s look at some of the most common reasons.

Depending on the issue you are having, it is important to understand the best ways to approach the handling of an LCD projector screen. On most projectors, the LCD screen is located within the optical unit of the device. One of the most common issues is dirt and stains stuck to the outer layer of the glass. This is by far the easiest problem to fix because there is no need to disassemble the projector to access its components. On our example project, we can see that there are stains and some dirt accumulating on the screen.

The black dots tell us there is some dirt stuck to the screen. The shadowy smear is probably a stain. For this simple cleaning job, it is important to know the best tools you’ll need to proceed.

One of the biggest mistakes people make when attempting to clean an LCD projector screen is rubbing their fingers on the screen to try and eliminate the issue, but this may cause further problems as hands tend to leave smears and stains on screens. If enough pressure is added you can actually damage the screen. To remove all the dust, dirt, and stains from the outer layer of the screen you will need:

Prepare the Lint-free cloth by moisturizing it with the isopropyl alcohol or water. Feel free to use the alcohol-water blend if you want the alcohol to last longer. Make sure the cloth is not soaking wet or too dry. Once you have your cleaning materials ready proceed to the next step.

Now comes the fun part! Clean the screen. Make sure you don’t apply too much pressure. Begin the cleaning using circular motions and remember to be gentle. The goal is to soak up the dirt or dust with a wet cloth. Most dust will get absorbed by the cloth and the dirt will loosen up. Any stain or smear should come right off when the alcohol is applied, this happens because pure alcohol is one of the best chemical solvents around. Once you have cleaned the screen, try passing a dry portion of the cloth to soak up all the remaining solution.

Now that you have cleaned the screen, you’re all set! Go ahead and test the projector and look out for any visual cues that might indicate that your cleaning wasn’t thorough enough.

Make sure you repeat this process as many times as possible till you see thing goes right. We recommend you keep the proper maintenance of your screen every time you use it. This is to allow the screen to remain as shiny and clear as possible. The more work you put into maintaining the LCD screen clean, the better the results will be. Save yourself the headache of seeing unwanted spots when you need to use the projector, and try to maintain it clean.

Most of these issues will require a bit more tech-savviness in order to be fixed. Remember that if you are to disassemble the projector you might lose any warranty. So be sure to handle all the components with care.

If you think the problem lies inside the projector’s optical unit, you can always disassemble the projector to see what is going on. We recommend you have your user manual with you in order to check what projector model you own. Do some internet research to check what type of LCD screen your projector houses, and if it can be replaced. The most common problem is the dust has entered through the cooling fan accumulating near the optical unit. To fix this you’ll need:

Remember that before accessing any components the projector has to be off and unplugged, this is extremely important so do not skip this. Simply remove the projector cover and try to see if any dust or dirt has accumulated. You can then proceed to clean it off using a small vacuum cleaner or some strong puffs of compressed air. Be sure to not allow any moisture o touch the components.

An often-overlooked reason why a projector might continue to stay dirty is the condition of your room. If the room where your projector is located tends to be filled with dust, we recommend you cover your projector with a cloth or a cover. Some projectors come with protective covers for this reason, so if you find out the conditions of your room are not ideal, maybe investing in some protection is a good option.

You can absolutely change the LCD screen of a projector. You can do this in a few simple steps. We recommend you contact the manufacturer to see how they can help you. Changing components inside a projector is a daunting task for most people, so you can save yourself the hassle by emailing or calling the manufacturer. If you want to do it yourself you can:

We hope you have learned a bit more about how projector LCD screens work. We also showed you some of the most common issues people run into with their projector LCD screens. How to keep the screen of your LCD projector clean is an easy task if you make sure you treat your unit with care and follow some simple instructions. Remember that most of the tools we used (e.g. water, lint-free cloth, isopropyl alcohol) are very common household items. So give it a go and enjoy your ‘newly-bought’ projector!

If dust collects on the air filter, clean it to ensure the best performance from your projector. Dust clogs prevent proper ventilation and cause overheating and damage to the projector. See Cleaning and Replacing the Air Filter.

If the dirt is difficult to remove or the filter is broken, you need to replace the filter. You can purchase air filters (part number V13H134A38) from your dealer or from the Epson Store.

Before you clean any part of the projector, turn it off and unplug the power cord. Never open any cover on the projector, except the lamp and filter covers.

2. To clean the filter, EPSON recommends using a small vacuum cleaner designed for computers and other office equipment. If you don"t have one, gently clean the filter using a very soft brush (such as an artist"s camel-hair brush).

Do not use glass cleaner or any harsh materials to clean the lens and do not subject the lens to any impacts; you may damage it. Do not use canned air, or the gases may leave a residue. Avoid touching the lens with your bare hands to prevent fingerprints on or damage to the lens surface.

[optional] To get it running you need to overwrite the switch next to the lamp as you can see on the second picture. As soon as you plug the projector in there will be LIVE PARTS everywhere, continue with extreme caution!

You dont need to remove the pcb. Just use some clean and dry air to blow into the holes where the cable go through. If you use air or gas in cans, make sure to not freeze the panels! If you use a compressor make sure there is no oil or water in the air. Be careful with the nozzle, especially if it is made out of metall.
