**Question 1: The projector cannot be started.** Answer: First, check if the power cord is properly plugged in and if the power supply is normal. If there's no issue with power, it could be an internal problem with the projector. In such cases, it's recommended to contact the after-sales service center for inspection and repair. **Question 2: The projected image is not clear.** Answer: This could be due to improper distance between the projector and the screen, dirty or aged lens, or a problem with the internal light source of the projector. Check the distance between the projector and the screen to ensure it's within the optimal projection range. Clean or replace the lens if necessary. If the issue persists, consider checking if the light source needs to be replaced. **Question 3: There is a color deviation in the projected image.** Answer: This could be due to incorrect color settings or a decrease in color rendering caused by an aged bulb. Check the color settings of the projector to ensure they are set correctly. If the bulb has been in use for a long time, it may need to be replaced. **Question 4: The projector makes abnormal sounds.** Answer: This could be due to issues with the fan or cooling system, or a problem with the audio output device. Check if the cooling system of the projector is working normally. If the fan noise is too loud or abnormal, it may need to be cleaned or replaced. Also, check if the audio output device is properly connected and undamaged. **Question 5: How to maintain a projector?** Answer: Regularly clean the filter and surface dust of the projector to keep good ventilation. Avoid continuous use for long periods to give the machine rest time. Schedule professional maintenance and inspections to ensure the projector is in good condition.
