Projector Issues

Discoloration

If your projector is not laying colors properly on the screen or the image faints, there could be several expected reasons, such as a malfunctioning VGA cable or fainted lamp. Or maybe the file format you are trying to run is not supported. You should also turn off all unnecessary lights as bright light makes it difficult to detect colors in the image.

Dark Spots

If you can see black spots in the image, that indicate dust particles accumulated on a lens along the projection pathway. That is the primary reason behind these spots. Still, there’s a slight chance that physical damage has dented your projection screen, and there are scars on your projection screen that are not visible unless you introduce the projection.

Over Heating

The heating of your projector is natural as it shoots an enormous amount of light, and the light source also produces a certain amount of heat. But a proper ventilating system is installed in your projector to prevent overheating.

If your projector overheats, it is probably due to some blockage in your projector’s ventilating system. Or sometimes, if you use a size of lamp in your projector other than the default, it can produce excessive heat for which your projector has not primarily designed.

Tips to fix your projector

1. Examine All components

To fix the issue, we first need to detect the component that is causing problems. You have to check up the whole projector and see anything unusual such as a burning smell, a faint sound, a flashing light, or any dents.

Burning Smell

If you smell something burning, it is probably caused by the lamp as it produces a lot of light and heat as a by-product. You can check and replace the lamp. If the lamp is working fine, dust accumulates in the gaps, and it burned from the heat. You can clean and try to run, otherwise change the lamp.

Flashing Light

If you see a light flashing, it is pointing out a specific component that has issues. You can search online what such light means for your projector model, but mostly it refers to the lamp or the VGA cable.

Issues with VGA wire

Issues With Vga Wire

If the image does not form correctly, the reason behind it could be malfunctioning wire. You have to make sure if the cable is working correctly and not twisted or bent harshly. If that’s the case, you may have to change the wire.

Dent

If there’s a new physical dent, that’s probably the reason behind problems. You should take your projector to a mechanical expert and take his opinion.

2. Cleaning the Projection

It is necessary to clean your projector’s essential components, and if the image seems distorted or spots are there in the picture, you need to clean the parts of the projection pathway.

3. Lamp Check

If you have problems that the light is dim or the projection image is not clear, the reason behind this problem can be the lamp. You need to open and clean the lamp, or you have to change it if it is too old.
