Their performance and lifespan directly affect the usage efficiency and cost. Therefore, it is crucial to perform daily maintenance and upkeep to effectively prolong the service life of projectors and ensure their normal operation. Firstly, regular cleaning is necessary. Projectors will accumulate dust during use, leading to reduced cooling efficiency, which affects projection quality and bulb lifespan. Therefore, it is necessary to clean the projector regularly, including the body surface, cooling holes, and lens. When cleaning, be sure to disconnect the power to prevent electrocution.

Secondly, correct power-on and power-off procedures should be followed. When using the projector, follow the correct sequence of powering on and off. Turn on the projector first, then the signal source; when shutting down, turn off the signal source first, then disconnect the projector power to protect the projector's circuitry and bulb and extend its lifespan. Thirdly, avoid excessive use. The bulb lifespan of a projector is limited, and excessive use will shorten its lifespan. Therefore, it is essential to arrange the usage time reasonably and avoid continuous long-term operation when using the projector. Additionally, when not in use, it is advisable to turn off the projector to save energy and prolong its service life. Fourthly, ensure good ventilation. Projectors generate heat when in use, so a good ventilation environment is needed. When in use, ensure that there are no obstacles blocking the ventilation holes around the projector to ensure effective cooling. Finally, regular inspection and updating are essential. Regularly inspect and maintain projectors, timely replace aging components and consumables, and update drivers and firmware as needed to ensure the performance and stability of the projector.
