A projector can make your night enjoyable when watching a favorite movie with family members on the bigger screen.
But at the same time, if something goes wrong with your projector, it can be a real pain in the middle of the movie.
Multiple reasons can go wrong with your projector; one of the most common problems is that it keeps turning off automatically.
This problem is so annoying that you will be unable to watch your favorite movie or show due to random turning off regularly.
So, in this article, we will discuss why your projector keeps shutting down, some temporary hacks, and the reasons which can be avoided if proper care is done at the right time.
Reasons Behind Projector Keeps Turning Off
Faulty Power Supply
It occurs when your projector starts shutting off due to a faulty power supply. It can also be due to a damaged power cord not providing enough power to the projector.
Check Power Cord
One of the first things you need to do is check your projector’s power cord. If the cable is damaged, it must be replaced as soon as possible.
You should also check if the cord is plugged into the projector socket properly or not. If not, try to plug it in again and see if the problem is solved.
If you are still facing the same problem, then there can be an issue with the power outlet. Try to plug the projector into another outlet and see if it is working or not.
Another thing that you need to check is the fuse. If the fuse is blown, it must be replaced with a new one. Also, if there is some problem with the power outlet, it can cause the fuse to blow.
Tip: Always keep a spare fuse with you so that you can replace it when needed.
Check Current Outlet
As we have mentioned before, one of the reasons for which your projector may keep shutting down is a faulty power outlet.
If the current outlet is not working properly, it will not be able to provide enough power to the projector, and as a result, it will keep shutting down.
Many people plug any device with the same power outlet, which can create problems. If you are using an extension cord, ensure it is not damaged and is of good quality.
This is the most common issue with older projectors as with time, and they start producing lots of heat when running for a few hours.
If you are using your projector for a long time, it can overheat, and as a result, it will turn off automatically. So what are the most prominent reasons for overheating issues? Let’s discuss them in detail below?
Clogged Air Filter
The current generation projector comes with an in-built sensor that detects the temperature rise, and if it is too high, it will automatically turn off the projector to save it from damage.
Sometimes the filter gets clogged, and then the rise of temperature increases, leading to the projector’s random shutdown.
So, before starting the process, ensure the projector is unplugged and has cooled down completely. Also, it’s not difficult to change an air filter cartridge that only requires a few tools.
One of the most important things you need to do is provide proper ventilation to your projector. If you are using your projector in a closed space, it can overheat, and as a result, it will turn off automatically.
Also, kids sometimes put their toys or other things in front of the projector’s exhaust, leading to overheating.
So, always make sure that there is enough space around your projector. You can also use a fan to keep the projector cool.
Using in High Temperature
Now due to climate change (currently in my city Georgia) witnessing the highest heatwave in any decade. The temperature is soaring high, and it is affecting the electronics devices too.
So, if you are using your projector at a higher temperature, it can overheat in a few hours if the brightness level is high, and as a result, it will turn off automatically.
Check Projector Fan
Many owners clean the projector from time to time, but in the case of a fan, it requires regular cleaning due to dust in the environment.
Your projector is shutting off randomly due to overheating because the “fan might not be working properly.”
Clean Projector Fan
If you have not cleaned the projector fan for a long time, then it might be filled with dust and will not be able to work correctly.
So, always make sure that you clean the projector fan on a regular basis. You can use a brush or a vacuum cleaner to clean the fan.
Replace it with a new one
If you know how to replace the projector fan, order it directly from the manufacturer and replace it with a new one.
But if you are unsure, we suggest you take it to a projector repair shop to replace the fan or call manufacturer customer care. They will handle the problem professionally.
If you are in a situation where you need to use the projector urgently and don’t have time to replace the air filter, then follow the below steps which might help you start the projector for a few minutes.
Why Does My Projector Keep Turning Off [Temporary Fix]
- Open the projector filter door and start the projector, but ensure no one is around the unit while it’s running.
- The airflow will increase and will help the projector to cool down.
- You can use a paperclip or any other small object to open the door.
- Once the projector has cooled down, you can close the door and use the projector.
Use a Small Fan
This method will only work when a small fan is available, the projector has an overheating issue, or the fan is not working properly.
First, place the fan one foot away from the projector. Please do not put it in front of the projector fan from where the warm air passes.
Because if you place it in front of the fan, the warm air will get stuck inside the projector, and you will see the temperature rise quickly.
Now, start the projector and let it run for a few minutes. Now turn on the fan, and you will notice the temperature will start dropping, and you will see there is no random turning off.
How to stop the projector from shutting down automatically?
The easiest way to stop the projector from shutting down is to keep the projector cool. You can do this by cleaning the projector fan regularly.
What are some common projector issues?
Some common projector issues are overheating, fan not working correctly, clogged air filter, and batteries are not working.
Why does standby mode exist for projectors?
Standby mode exists for projectors because it conserves energy when the projector is not in use. It will enter standby mode when the projector shuts off automatically or randomly.
This is beneficial because it can help prolong the projector’s life and save energy.
Everyone loves to watch their favorite movies or episodes on the bigger screen with the help of a projector. But when the projector starts behaving oddly, then it hampers the movie experience when the climax is coming to an end.
So if that case is happening with you, follow the above easy steps, and hopefully, they will help you fix your projector.
