What to Do If Your Projector Screen Shows Yellow Spots or Black Dots?

For many home theater fans, picture quality is everything. A clear and vibrant image sets the tone for the entire experience. But sometimes, after a period of use, you may notice yellow spots or black dots appearing on the screen. Not only can this be distracting, but it can also affect the overall enjoyment of your favorite movies or shows. So why does this happen, and what can you do about it?

Why Do Yellow Spots and Black Dots Appear?

Yellow spots usually occur when the internal optical system of a projector overheats, or when the lens begins to age. Over time, high temperatures can cause certain components to discolor slightly, which then shows up on the projected image as yellowish marks.

Black dots are often caused by dust, smoke particles, or tiny foreign objects entering the optical path. When these particles stick to the LCD panel or lens, they appear as dark dots on the screen.

Special Case: Early Batches of the Q5

Since the VOPLLS Q5 is a newly released model, a small number of units from early production batches in certain regions did experience black dot issues. This was due to a serious production bug.

If you have received a Q5 and noticed black dots on the image, please contact our after-sales team immediately:
📧 voplls@vskingtech.com     (after-sales team)
📧 vopllsofficial@gmail.com    (Brand Department)

When reaching out, please clearly describe the problem and attach a photo of the black dots. Our support team will arrange a replacement projector for you right away.

The good news is that we have already identified the root cause of this issue and fixed it. Future Q5 units will no longer experience this problem. We sincerely thank our users for their feedback and patience, which helps us continuously improve our products.

How to Prevent Yellow Spots and Black Dots?

• Regular cleaning
  Clean the ventilation inlets and filters of your projector regularly to prevent dust buildup, which can reduce the chance of black dots.

• Good ventilation
  Make sure your projector has proper airflow during use. Avoid placing it in a sealed or overheated environment, as this will help extend the lifespan of the optical components.

• Professional service
  If the issue has already become severe, contact professional service or your after-sales team for internal cleaning or part replacement.

Choosing the Right Projector Matters

The best way to avoid these issues is to choose a projector with a stable cooling system and a well-sealed optical design. For example, models like the VOPLLS M10 and the updated Q5 are designed with heat management and dust prevention in mind, ensuring a clearer and longer-lasting viewing experience.

Final Thoughts

Yellow spots and black dots don’t mean your projector is beyond repair. With simple maintenance, proper room conditions, and the right equipment, you can minimize these problems and keep your home theater experience enjoyable.
