A quality projector is a major investment, especially if you're purchasing one to act as central entertainment hub in place of a smart TV. Projectors can be a bit more delicate than a TV, and tend to require some more care and maintenance, particularly when it comes to the lenses and fans. The build of your projector as well as its quality will influence the extent to which you'll need to tend to it, but every model requires at least some basic attention.
Watch out for dust in the vents
Clean or replace filters as necessary
One part of regular projector maintenance is tending to the lens and any vents present. The build up of dust over time is both common and problematic, as dust can lead to performance issues, overheating, and an increase in noise. All of this can add up to a shorter lifespan for your projector.
The best way to deal with dust and other particles that may interact with the fans is with compressed air. Be sure to use best practices, including spraying from a distance of 4 to 6 inches and doing so in a well-ventilated area. If your projector has filters, you'll need to remove them regularly and clean out dust with a vacuum or dry cloth. Even with regular cleaning, they are likely to wear down and require replacement over time.
Keep the projector lens pristine
Clean and protect this vital component
One of the most important parts of the projector is its lens; you need to keep the lens clean in order to enjoy your favorite media. While cleaning the lens is fairly straightforward, it does need to be taken with considerable care.
A projector lens is very delicate. Avoid touching it directly with your fingers and never spray any liquids on the surface when cleaning.
The best way to clean most projector lenses is with a microfiber cloth. The soft material is ideal for collecting dust and wiping away smudges without scratching or marring the lens itself. Use a dry cloth and wipe gently; if any smudges remain, only then should you consider adding a bit of water to the cloth and then using the slightly damp surface for removal. Only clean the lens well after use when the unit has cooled off.
Use a lens cap if included with your projector; if not, consider investing in one or creating a DIY option to protect the lens when not in use. Avoid touching the lens when moving the unit, and make sure it's completely protected whenever you are storing the projector.
Adhere to best operational practices when in use
Maintain software updates and security
If you have a mid-range or high-end projector, or any model that includes a smart system, you're going to want to treat it like the computer it is. That means making sure you're keeping it protected and private by maintaining updates, keeping it on a secure network, and using strong passwords for various accounts.
Concerning hardware, use proper HDMI cables and make sure you have a suitable power source that is capable of properly supporting your projector. Many models of projectors take time to turn on and off, so you'll want to avoid any sudden shutdowns. Use a surge protector if possible and never unplug the power source to power down the unit.
Operate in the right environment
Maintain distance, ventilation, and cleanliness
It's important to be mindful of the environment around your projector, both when it's in use and when it's sitting idle. Make sure it has room to breathe; you need space around the projector for proper air circulation and to avoid rapid dust accumulation. You want to keep it away from enclosed spaces; mounting, particularly on the ceiling, makes for an ideal setup.
They should be used and stored in a dry, cool environment. Excessive moisture and high temperatures are problematic and could cause performance issues in the present and deterioration over time. While home projectors are often set up in basements, you'll need to be careful when it comes to air temperature and humidity. When not in use over a prolonged period of time, store carefully to protect it from any adverse elements.
Handle with care and exercise patience
Complex projectors call for extra attention
Your projector is delicate, and so everything you do should come with some patience and caution. High-end models, for example, take time to turn on and turn off. You'll want to avoid moving or doing any cleaning until the projector has fully powered down and completely cooled. While it's on, you'll want to avoid moving the model so that there are no misalignment issues.
With all the cleaning procedures, it's best to come up with a schedule and tend to the projector every four to six weeks.
Perhaps most important is that there are many different kinds of projectors, and each will have its own specific maintenance practices. Read the user manual, adhere to recommendations put forth by the manufacturers, and treat your investment with the care it deserves.
