Best Solutions for Home Projector Keeps Turning Off Issues

Why My Projector Automatically Turns Off?

There are several reasons as to why your projector may automatically turn off. The first reason is that the projector may have entered standby mode after a period of inactivity. However, all you need to do is push the power button again to wake the projector.

The second reason for the projector shutting off is when the projector's lamp shuts off. When the power and temp lights are red, it means the projector has overheated, thus, automatically will turn off.

Filter warning is another reason why your projector might shut off. This happens when the air filter sensor detects the filters are clogged. Then, the LED indicator will turn on to indicate that the filter should be replaced or cleaned. The process would depend on the model.

In cases where the projector may face an internal failure, this will lead to it shutting off completely. Repairing the damage from within the projector is necessary; otherwise, there's no other way to turn It back on.

Continue reading as we'll discuss everything you need to know about your projector, the problems that occur, and how you can fix them.

What Happens When Projector Overheats?

This a common problem that occurs, and most projector owners don't know why or how to deal with it. Projectors tend to overheat if you're using the projector in a warm room. This can cause the device to overheat because no cooling occurs when the air the fan pulls in is the same temperature as the warm air released from the projector. Besides, filter will be filled with dust if it is not cleaned regularly which may also cause overheat of the projector.

Make sure you use your projector in a cool environment so that your projector doesn't overheat often. And do clean the internal part of your projector regularly to avoid being blocked by dust. However, if you don't take this seriously, not only will your projector overheat, but there is a risk of damaging the projector internally too.

Is Your Projector Properly Connected?

Depending on what you're connecting your projector, the methods of connection are different. If you're facing issues with the display, whether it's not visible or unclear, you need to make sure the connections are properly set.

For instance, if you're using a laptop, you must note that the projectors have multiple inputs, and if the one you're using isn't selected, you won't receive any images. In case you're using HDMI, check to make sure the projector is using HDMI and also the HDMI to which the laptop is connected.

However, if you're using a computer, then press down on the Windows logo icon on the keyboard. Press "P" to fetch up the projector screen. Click "Duplicate" to share the picture on the computer screen and projector. Click "Extend" to extend the image to the projector.

Cautious Considerations Before Starting Your Projector

Many people tend to forget that the bright light of the projector is harmful to their skin, so standing in front of it is not a good practice. For any reason, if you have to stand near the light, for instance, during a presentation, make sure you're not directly in the line of the light. Not only is it bad for your skin, but it can also harm your eyes.

Avoid placing your projector or an unstable platform, as this will cause problems with the image. Other than this, make sure not to tilt the projector to one side while using it. This can cause damages internally as the device is to be set still in one particular position only.

Learn to Solve the Auto Turn-Off Project Problems

Projectors have an auto turn off system which occurs when there is no activity or depending on the time set for maximum usage. The bulbs used in the projector can get damaged if used for too long. That is why this system is popular and found in most of the projectors.

To solve this, you may increase the timer even more so that when you don't need to use it further, you may turn it off manually or you can undo the auto turn off. But in this case, you may always need to keep it in your mind to turn off the projector by yourself.

Apart from the things mentioned above, auto turn off may happen because of the aging protector. Customers hereby are suggested to contact the after-sale service from where they purchased the product.

Projection: Other Common Issues

Projectors are a popular product as people in conferences and business meetings use the projector for presentations. The projects typically have issues with their picture quality; below are some of the other problems your projector may face.

1. Purple Dots on the Screen

Purple dots on the screen affect the quality of images beamed out by an LCD projector. These are quite annoying to look at and ruins the whole image. Dust and dirt particles are the main reason this happens because they accumulate on the projector's green panel. Cleaning the projector will help you avoid this issue.

2. Projector Not Turning Off

You're pressing the power button, and still, the projector tends not to turn off. The reason for this problem to occur is a not correctly fitted lamp assembly. To solve this problem, fit the lamp properly or have a technician do it for you.

3. Poor Image Quality

Image quality is essential, or it beats the purpose of owning a projector. An unaligned computer resolution results in poor image quality and this is quite a problem.

All you have to do to resolve this matter is to adjust the resolution until the images get better.

4. Images Don't Display Fully

It is a common error that occurs when the computer's resolution and projector resolution is not aligned correctly. This causes the image or text to not show from a certain angle on the screen.

To solve this problem, adjust the resolutions and align them together properly. In case you're using a laptop, and this doesn't work, disable your laptop from the desktop first then continue.

5. Remote Controls Not Working

The reason behind remote controls not working is simple. Either the batteries are weak, or the distance between the remotes sensor and projectors sensor is more than the recommended range. Thus solving this problem will take no extra time or effort. Just change the batteries and make sure the range isn't too much.

6. The Projector is not Turning On When Pushing the Power Button

Firstly check if the outlet in which the Projectors connection has power or not. Some projectors have "indicator" or "status" LED lights on the control panel. If this light is on or flashing, you should look into your owner's manual or manufacturer's website for solutions and explanations. Don't fiddle around with it on your own as you might do more damage.

7. The Projector Powers On; However, the LED Light on the Top is Still Blinking

Every projector is different, and the way to solve their problems is different too. If your projector LED light is continuously blinking, then it means the projector lamp is exhausted.

Why does this happen? Well, the average lamp hours range from 1,500 to 2,000 hours. Most projectors use a checker to keep track of the number of hours used. A notification will show up on the screen when the usage is too much.

To solve this problem, you'll have to contact a technician for a lamp replacement and make sure the right lamp fitting is according to the model of your projector.


The problems you will face before starting your projector during usage and once finished using it may vary. You must make sure that you're following the protocols to ensure the well being of your projector. Otherwise, you will come across more issues regularly.

The problems mentioned above all have a solution, and in case you don't have a remedy to treat it, contact your projectors manufacturer for assistance on it. You may also go through the manual provided with the projector for further details in regards to your concern.

If you come face to face with any of the above issues, just follow the mentioned information provided for a better way to treat your projectors problem.
