Why do projectors blink?
Every project is different, and so can be the reason for the blinking. But there are some common reasons which are usually responsible for a blinking projector. You can always try to reduce the flickering by yourself before spending hundreds of dollars for professional help. We have prepared a list of 5 reasons which are responsible for the blinking of the projector.
- Worn-out or damaged bulb
A bulb consists of two anodes. When a bulb is new, these anodes are sharp, but with time and continuous usage, the anodes get flattened. Due to this, the gap lessens and the arc jumps across the gap. This causes arc instability resulting in blinking.
- Damaged lighting components
If the projector is still flickering even after changing the bulb, there May be some problem with the lighting components. The lighting system of a projector consists of a series of mirrors, lenses, and prisms. These are known as elements. The elements reflect and split the light. The bulb then lights the image through the mirror, and the light is passed through the lens of the projector. There may be some defects in the components.
- Electric surge
The projector may also flicker due to an uneven electric supply. There may be some fault in the wall switch or the electric line.
- Refresh rate
The refresh rate of an image is defined by the number of times an image is regenerated in a given time. The refresh rate is measured in Hertz. If the refresh rate of an image is 70 Hertz, it means that the image is regenerated 70 times per second. If the refresh rate decreases, the flickering increases.
- Frame rate
Frame rate is defined as the frequency at which consecutive images are displayed. The higher the frame rate, the lower the flickering. However, in some cases, flickering occurs because the frame rates of the projector and the movie are different.
How to troubleshoot a blinking projector?
Above we listed and explained the reasons why your projector may be blinking. Now let’s discuss how to correct these.
- Worn-out or damaged bulb
If your projector is blinking because the bulb is worn out or damaged, you can correct the blinking by simply changing the bulb.
- Damaged lighting components
The lighting system of a projector consists of a series of mirrors, lenses, and prisms. These are known as elements. The elements reflect and split the light. The bulb then lights the image through the mirror, and the light is passed through the lens of the projector. If there is some fault in the lighting components, you have to change the lighting components to mend the blinking.
- Electric surge
If the projector is blinking due to an electric surge, you need to purchase a surge protector to protect your projector. Or there may be some fault in the switch; you should also get it checked.
- Refresh rate
If the refresh rate decreases, the flickering increases. To correct your blinking projector, you have to increase the refresh rate, and the blinking will stop.
- Frame rate
The higher the frame rate, the lower the flickering. However, in some cases, flickering occurs because the frame rates of the projector and the movie are different. To stop the blinking, make sure the frame rate is high or the movie and projector have the same frame rate.
How to solve problems you may face while installing a new bulb
- The projector will not switch on
If the projector is not turning on, check the power chord and connection properly. Also, check the lamp cover. If the lamp cover is not properly closed, the projector will not work. Also, check if the bulb is installed properly. Do not screw the projector too loosely or too tight.
- Overheating
Overheating in projectors is caused when the ventilation holes are clogged with dust. Projectors have fans as a cooling system as they operate on high heat. The fans cool down the components of the projector by blowing air. When dust gathers on the components, it prevents cooling. To solve this problem, you can remove the dust particles with the help of a vacuum cleaner pipe. You should always vacuum and clean off the dust before replacing the bulb.
- Error message on the screen
Projectors consist of a lamp timer. Lamp timers track the usage of lamps automatically. They are programmed to send a message if there is any problem with the lamp. Sometimes a message appears stating that you should change the lamp even after replacing the lamp. Therefore you should always reset the lamp timer before replacing the bulb.
- The picture is dimmer
Sometimes after replacing the bulb, the picture appears duller. This may be because the bulb is not positioned in the center of the lamp housing cage.
- Projector gets turned off automatically
The projector may turn off automatically if it detects a problem. If this happens even after clearing off the dust, you should change the brand of your bulb from a generic one to a more reputable brand.
- The screen color is incorrect
The lighting system of a projector consists of a series of mirrors, lenses, and prisms. These are known as elements. The elements reflect and split the light. The bulb then lights the image through the mirror, and the light is passed through the lens of the projector. There may be some defects in the components. To check out more, click here.
