Reason and How to fix projector flickering.

We are going to talk about the reason for the projector flickering and how it can be resolved.

Eco Mode

Generally, people use eco mode for the projection. So they can use the projector for a long time. Or their projector light source life can be increased. 

This step helps you to use the projector for a long time. But sometimes this projector mode becomes the reason for the screen flickering. For the projection. Your lamp should need a certain amount of power. 

And in eco mode. Your projector lamp is unable to get that amount of power. That’s why your screen is flickering. So how can you overcome this issue?

You have to move from the eco mode to normal or high mode. In your projector. Not for permanent. Don’t worry. Change this setting after some hours of use. And your issue will be resolved.

So that’s how you will deal with the flickering screen. Try this one. Then move for the next remedy of flickering.

Damage bulb

There is an anode in your projector lamp. Which generates the arc. When the projector is plugged into the power outlet. With a long time of use of the projector. Projector lamp anode got faltered. 

And when the projector is plugged with the power source. Arc generated on the tip of the lamp anode. And that arc does not fall off the other anode. 

And the arc falls somewhere else. Which causes the issue. And you see the flickers screen. There are four ways. You can solve this issue. If the projector bulb or image is flickering. Because of this reason. 

You can change your projector power consumption mode. Or you can also try to change the picture mode. If all these things don’t work. You have to change your projector lamp. For that see the below video.

Or get the laser projector. 

Electrical surges

An electrical surge is pretty common in the household. It’s happening because of the up and down of the electricity in your home. So when you plug your projector in your power outlet. 

It makes a crackling sound. And while using the projector. It’s seen on your projector. As a flickering screen. Which is very irritating. For everyone.

For this, you can try a different wall outlet. In your home. For the power source. Or if there is a problem with the electricity in your home. 

You should call the electrician. To solve this issue. The last thing you can do. You can use the surge protector. To solve this issue.

Components have broken

In the projector, there is various glass projection part used in the projector. Which completes the projection in any projector. By reflecting the light towards the final destination.

If you have ever opened the projector. It might be possible. You have accidentally touched the projector-sensitive glass projection part. And it hurts the glass parts of the projector.

To resolve it you have to change the glass projector parts. Which causes the issue. I will suggest that you should call the professional. Because you don’t want to hurt your projector.

Ground Loops

Ground loops happen. When you plug the two different devices in the two different power outlets. If you are using the projector and with a separate video source.

And that device is connected to a different power source. From the projector. Then it is a hundred percent sure. You are facing a flickering issue. Because of the ground loops. 

For that, you should connect the projector and video source device with the same power source. So you can get rid of the flickering issue. In your projector.

Frame Rate, Refresh rate 

A low frame or refresh rate also causes the screen flickering. So go to your projector frame rate setting. And check its frame rate. If it is low then. Change your projector frame rate. And increase the frame or refresh rate of your projector. It will help you to resolve the issue. 

Color Wheel

Because of the regular use of the projector. Collect the dust inside the projector. All over inside the projector. But here we will only talk about the dust on the color wheel.

When dust is collected over the color wheel. It makes the flickering on the screen. Because the color wheel is part of the projector. Which converts a white light source projector into a different primary color.

You don’t need to get into too many technical things. But you should know if your projector is a DLP projector. Then it could be the reason for your projector flickering. For that, you have to open the projector and have to clean the color wheel in the projector.
