How to use the maintenance of the projector?
With the development of society, more and more high-tech products have entered people's lives. The projector, which is projected or reflected on the screen through technical techniques such as digital light processing, is no exception. As a projector, projectors are widely used in various places. However, such sophisticated equipment is not fully understood how to use and maintain. Today Xiaobian projectors share the use and maintenance of the projectors.
The pole meter is a miniature projector that uses an LED light source. It is a light bulb that is not a light bulb and has a lifetime of tens of thousands of hours. Physical resolution 1280*800. The reason why the name of the screenless TV is slogan is because the video processing program of the machine is completely in accordance with the standard of the TV. Compared with the smart TV sold outside, the only difference is the display mode. One is the LCD display. It is through projection.
Polar meters - using maintenance
The projector is a kind of precise electronic product, which integrates mechanical, liquid crystal or DMD, electronic circuit technology in one, so it should pay attention in the following aspects when using (take LCD projector as an example):
Mechanical protection against strong collisions, squeezing and vibrations. Because the strong earthquake can cause the displacement of the liquid crystal film, affecting the convergence of the three LCDs during the screening, and the phenomenon of RGB colors not overlapping, the lenses and mirrors in the optical system may also be deformed or damaged, affecting the image projection effect, and the zoom The lens will damage the track under impact, causing the lens to become stuck, even if the lens is broken and cannot be used.
The optical system pays attention to dust and ventilation heat dissipation in the use environment. The newer models are equipped with temperature sensors near the LCD panel. When the air inlet and the filter network are blocked and the air flow is not smooth, the temperature inside the projector will rapidly increase. At this time, the temperature sensor will alarm and immediately cut off the light source circuit. . Therefore, it is necessary to keep the air intake open and clean the filter in time.
The light source part is forbidden to vibrate when it is turned on. Move the projector to prevent the light bulb from bursting. The power supply cannot be turned off immediately after stopping use. The machine should be automatically shut down after the heat dissipation is completed. The damage caused by the power failure in the heat dissipation state of the machine is the most common projector. One of the reasons for the repair. In addition, reducing the number of switches is beneficial to lamp life.
It is strictly forbidden to insert and pull the cable in the circuit part, and it is better to connect the signal source and the projector power to the ground at the same time. This is because when the projector and the signal source (such as a PC) are connected to different power sources, there may be a higher potential difference between the two zero lines. When the user inserts or unplugs the signal line or other circuit, a sparking phenomenon may occur between the plug and the socket, which damages the signal input circuit, thereby causing serious consequences.
The above is the maintenance and maintenance of the mega projector for everyone to share. I believe that it will help everyone, but it is also worth mentioning here is that no matter what happens to the projector, the user will not be able to view the machine privately. There are no parts that users can handle on their own, and the high-voltage equipment inside the projector may cause great damage to the human body. When purchasing, it is not only necessary to choose a good product to find a good price, but also to select a good business and find out the maintenance service calls. If you have any questions, consult a professional, and you will not have any worries and hope to help everyone.
