Answer: This may be due to the aging or poor quality of the projector's lamp, or the incorrect placement of the projector. You can try replacing the lamp with a new one and ensure that the projector is placed in a well-lit and unobstructed open space. Additionally, check if the lens of the projector is contaminated or covered with dust. If necessary, use a cleaning agent or a dust-free cloth to clean it. Q2: The color of the projection screen is off.

Answer: This may be due to the color adjustment of the projector itself or related to the projection environment. You can try adjusting the colors of the projector and check if the color mode is set correctly. At the same time, ensure that the light in the projection environment is evenly distributed to avoid strong or dark lights affecting color representation.

Q3: The projector cannot start normally. Answer: First, check if the power cord is properly plugged in, and if the power plug is loose or damaged. If the power is normal but the projector still cannot start, it may be an internal circuit problem. It is recommended to contact professional maintenance personnel for inspection and repair. Q4: The projection screen appears blurry or double-imaged. Answer: This may be due to lens contamination or improper adjustment of the projector. You can try cleaning the lens or adjusting the focal length and direction of the lens. Additionally, check if the signal source is stable to avoid blurry images caused by signal interference. Q5: Excessive noise. Answer: This may be caused by the fan's operation resulting in excessive noise. If this is the case, it is recommended to clean the dust around the fan and replace it with a new one if necessary. At the same time, be sure to avoid placing the projector in a poorly ventilated environment that may affect heat dissipation and increase noise levels.
