Black Lines or Dark Areas on the Screen

Projectors rely on internal cooling systems to maintain stable operating temperatures. If the device runs in a poorly ventilated environment for extended periods, internal temperatures may increase and affect the projection panel or optical components.
This may result in visual artifacts such as lines, dark areas, or image irregularities.

What you can do:
** Contact our support team for assistance [Sainyervip@gmail.com].
** Customers who have activated their warranty may qualify for a one-time replacement, even beyond the standard marketplace return window.

To help prevent this issue, place the projector in a well-ventilated area and avoid blocking the ventilation ports.
