Not being able to determine why your projector is causing so much noise? I have listed a few common issues that cause your projector to be noisy and solutions that can help you fix them. Check them out!
Have you ever wondered why your projector is creating a buzzing sound?
Is it because of the fan or something else?
I understand that an intense film’s climax can get ruined because of a loud Projector.
In this article today, I will talk about every possible reason that causes a projector to be noisy and how to get rid of it. So that the next time you call your friends over for a movie night, you won’t be embarrassed with your projector.
Why does the projector fan turn noisy? Tips to Reduce Projector Noise
In most circumstances, you will see the noise in the projector created by the fan working inside it. There can be multiple reasons that cause the fans to become noisy. However, for whatever reason, there is a solution to every problem once you have identified it.
Below are a few obvious reasons that cause the projector fans to grow louder and how to fix it.
As mentioned above, the most common reason behind a projector’s noise is its fan. Usually, when a projector heats up, the fans work harder to cool it down, which results in noise.
And there are multiple reasons for the projector to get heated up. I am going to talk about it later in this post. However, you can read it in detail here. Projector Overheating issues, why it overheats, and how to fix it.
Turn the projector off and let it cool for a while. Then, try it again and check if the issue persists.
The projector’s overheating is not the sole reason for the noise. Suppose you hear a whirring sound coming out of the projector or some crackling or grinding noises from your projector.
These sounds indicate a mechanical or electrical failure inside the projector that needs immediate attention.
The only solution to this problem is to call a technician. If you’re a tech guy, you can try fixing it yourself once.
2. Bad ventilation:
A projector has several components inside it that generate heat. The projectors get heated primarily because of the bulb that creates light to project images.
Fans inside the projector throw the hot air out from the ventilators and pull in cool air to cool the projector.
These fans work best when nothing surrounds the projectors except the cool air. But unfortunately, it doesn’t always happen.
There are times the projector is placed in a hot or humid room or surrounded by other electronic objects that create heat. This causes the projectors to heat up more often.
Solution: How to fix the bad Ventilation issue on your projector?
To ensure proper ventilation, you should make sure the projector is placed in a cool room or else place the projector in an air-conditioned room where the temperature can be monitored.
It would help if you also ensured no electrical gadgets that create heat are placed near the projector. And if you keep them, ensure they are turned off while the projector is running.
You can opt for ceiling installation using normal projectors to ensure proper ventilation. When a projector is installed in the ceiling, you don’t have to worry about anything obstructing the ventilators.
3. Running time: The projector is being used at a stretch
Prolonged use can generate heat in projectors. This is because when you continuously run a projector, the projector bulb constantly generates heat to project images. As a result, the projector is getting heated up.
I recommend limiting your watching time. Don’t watch an entire series of 20 episodes or a cricket test series at a go to avoid the projector from getting heated up.
Divide your time when watching something on a projector and switch it off after a few hours to ensure it cools down completely until you switch it on again.
This will not only help generate less heat causing the fan to create less noise, but also increase the shelf life of the bulb inside the projector.
4. Dust: The accumulation of dirt and dust around the projector
Whether your projector is installed on the ceiling or the table, you must regularly clean it and its surroundings to ensure dirt and dust do not block the ventilators.
If you do not clean the surface of the projector and its surroundings, the dust particles will block the ventilators and cause the fan to run harder, causing the noise.
It will also heat the projector because the fan cannot pull in cool air from the ventilators and throw out the hot air.
Solution: How to get rid of the dust and dirt around your projector?
To ensure dirt and dust do not block the ventilators of the projectors, wipe the projector with a damp cloth.
You can either use cleaning wipes or alcohol as a cleaning agent to clean the surface.
Just make sure you do not pour too much of it. The cloth used to clean the surface should not be soaked wet.
To clean the inside of the projector, you should use a computer duster.
If your projector is installed in the ceiling, watch out for cobwebs that can jam the projector fans resulting in noise.
5. Electrical or mechanical failure
Merely ensuring the projector is kept in a cool place and not playing it too long might not be enough. Sometimes, your projector turns out to be noisy because of an electrical or mechanical failure.
How do you recognize your projector has an electrical or mechanical failure?
The easiest way to identify a technical problem is to identify the noise. Suppose you hear a grinding, buzzing, or crackling sound. If the sound of the projector’s fan is not as smooth as it used to be, you can rest assured that it is time to call for a technician.
Suppose you sense any abnormal sound coming out of the projector that does not subside even after cleaning the projector or cooling the projector down.
In that case, you should call a technician immediately. As the famous saying goes, “a stitch in time saves nine” any minor electrical failure can lead to massive consequences if not addressed on time. The same goes for a mechanical fault.
How to take care of your projector?
Here are some projector maintenance tips,
- Ensure the projectors are cleaned and dusted regularly.
- Keep nothing in front of the projector that blocks the ventilators. It forces the projector fans to work harder and create noise.
- Please switch off the projector regularly to avoid overheating.
- If you hear any unusual noises from the projector, call for technical help before it is too late.
FAQs: Frequently Asked Questions
Of course. Every projector requires maintenance because even a small worn-out electrical connection, dust, or overheating can lead to a massive electrical or mechanical failure if not addressed on time.
I suggest you never ignore projector noises, no matter how small the issue is. It affects not only your viewing experience negatively but also your projector’s overall shelf life.
Conclusion: So, why do projectors make noise?
I can say that there are ample reasons that can make your projector noisy, but most of them are not severe. These problems can be easily eliminated if you maintain the projectors properly.
Therefore, before you draw any conclusions, listen to the sounds carefully coming out of your projector before you take the call.
Following the above tips and solutions, you can troubleshoot the problem in nine out of ten scenarios. Do not hesitate to reach out to me in case of any clarifications or call for a technician in case you sense there is some other problem that is causing your projector to be so noisy.
