Does your device have any of the following issues?
• The projector does not display anything on the screen or output sound when
it is turned on.
• The product emits smoke or a burning smell.
• Water or foreign substances are present inside the product.
•
Part of the projected image is cut out.

A strange noise (crackling or sparking sound) regularly occurs from inside the
projector.
•
The projector still displays the screen or outputs sound when it is turned off.

There are other errors or failures.
In this case, stop using the product.
• For safety, turn off the power switch and remove the plug from the socket.

Abnormal behavior
•
There is a colored dot (bright dots, dark dots, stationary dots, and/or flickering
dots) on the screen.
– This projector was produced with high precision technology. However, a tiny
dark or bright dot may appear on the screen. This is a common occurrence
due to the production process, and it does not indicate a functional failure.
• The remote control may not work properly where a lamp with electronic
stabilizer or a three-wavelength lamp is installed.
– In this case, replace the lamp with electronic stabilizer or the three-
wavelength lamp with international standard products to ensure the
remote control works properly.
