Disfunctioning DMD chip causes white dots on projector
If you notice white dots on your projector screen, it is likely that the DMD chip is not functioning properly. These chips can be found in the optical engine of the projector. To address this problem, start by unplugging the projector from the main switch. Next, it is necessary to remove the projector’s case.
White dots on a projector can be caused by a number of problems. First, the lens or bulb may be dirty or faulty. Another common problem is dust or other buildup on the lens. In the worst cases, a chip could be damaged or broken. If you’re not sure, consult a professional.

Cleaning the lens
One of the most effective ways to clean a projector lens is to use a soft cloth to wipe off visual debris. Avoid aggressive rubbing on the lens, as this can damage it. Instead, use circular motions to wipe from 360 degrees. You should also be careful not to touch the lens with your fingers, as it can cause scratches.
Cleaning the lens of a projector is an important step to improve the quality of your image. You should be careful, however, because the lens is made up of delicate optical components and glass. It is therefore important to use proper cleaning techniques to prevent damage to the glass and electronics.

Cleaning the internal projector
One of the most effective ways to get rid of white dots in your projector is to clean it regularly. You should clean it whenever you notice dust on the screen or smudges. Also, if you notice that your viewing experience has been affected, you should clean it. You can use a blower to remove the dust. However, it is important to use caution when using compressed air to clean the projector lens. This will blow away the dust, but may also leave residue behind.
If the dust is sticky and is on the optical parts, you should clean them using degreaser. The degreaser is usually the same as the one used on glasses. For smaller projectors, you will need special tools to clean the optics and realign the panels. If you are hearing a white noise coming from the projector, it may be caused by blown pixels or a failed absorber.

Overheating
Overheating a projector is not a good idea. It can damage its internal components, such as the LCD screen and the thermometer. It can also burn the images or cause white dots. Sometimes, some manufacturers make these errors when manufacturing the device, such as not including the proper settings. When this happens, the projector may work fine at first, but the screen will suddenly display tiny black or white dots. This condition may be temporary, or may appear over time.
The first solution for the problem is to replace the chip. It is similar to replacing a CPU processor. The DLP chip is a similar component, and replacement of this chip will make your projector work properly again. If you don’t want to spend a lot of time fixing your projector, try to turn off the power for 30 minutes.

Dead pixel
There are a few ways to get rid of dead pixels on a projector. First, make sure the projector is in full screen mode. Then, wipe the screen with a clean cloth. Next, check each colour to check if any is dead. Do not rub the pixels as this could cause more damage.
Dead pixels are the pixels on your screen that are not reflecting light. A dead pixel will show up as a black dot on the screen. Another symptom of a dead pixel is colored spots. This happens when a pixel is stuck in its on position. This can occur if a manufacturer has made an error in setting up the display chips.
Another cause of dead pixels is smudges on the projector’s components. This causes the projection to look distorted. To remove these stains, you need to clean the projector’s LCD panel.
