   • Check whether the power supply works normally and whether the power cord is loose.
   • Check whether the screen is running normally, and remove the dust on the product.
   • Check whether the box is blocked by debris, etc. If there is, remove the debris prevention.
   2)Others
   Check the installation to ensure safety.

2. Display Zone
   Regular dust on the surface of the screen, especially in the outdoor dusty environment. Due to the factors of the working environment, it is easy to be exposed to the sun and dust for a long time. On the one hand, dust removal can improve the display effect, and on the other hand, it can prevent the corrosion of the surface of the screen by the particulate matter in the air or other chemical factors under humid conditions. The application and maintenance of LED car ceiling light screens should pay attention to the following issues:
   (1). The power supply system is required to be stable and well-protected.
   (2). Do not use it as much as possible under harsh natural conditions. Such as strong thunder and lightning weather.
   (3). Metal objects that are easy to conduct electricity such as water and iron powder are strictly prohibited in the screen. The LED screens should be placed in a low-dust environment as much as possible. Large dust will affect the display effect, and too much dust will cause damage to the circuit.
   (4).If water enters due to various reasons, please turn off the power immediately and contact the maintenance personnel until the display panel in the screen is dry before use. Keep the humidity in the environment where the screen is used, and do not let anything with the nature of moisture enter your screen. Applying power to the screen that contains humidity will cause the components of the screen to corrode, resulting in permanent damage.
   ( 5) The use of the screen: A. Start the vehicle. After the car starts, the screen will be turned on, and the screen will be displayed in about 1 minute. B. After turning off the ignition switch, the screen will automatically turn off.
   (6). The surface of the screen can be wiped with alcohol, or dusted with a brush or a vacuum cleaner, and cannot be wiped directly with a damp cloth. To avoid possible problems, we can choose passive protection and active protection, try to keep items that may cause damage to away from the screen, and wipe the screen as gently as possible to avoid the possibility of injury to a minimum.
   (7). It is recommended that the screen rest for more than 2 hours a day and the screen should be used at least once a week during the rainy season Generally the screen is turned on at least once a month and it is lit for more than 2 hours
   (8). The screen needs to be checked regularly to see if it is working properly and whether the line is damaged If it does not work it should be replaced in time If the line is damaged it should be repaired or replaced in time
   (9). When playing do not stay in full white full red full green full blue and another full bright screen for a long time so as not to cause excessive long- term current excessive heating of the power cord damage to the LEDs and affect the service life of the display Do not disassemble or splice the screen at will
   (10). Nonprofessionals are not allowed to touch the internal circuit so as not to cause damage to the circuit, If there is a problem please ask a professional to repair it

3.  Storage
   (1)Preservation of accessories such as uninstalled screens and spare modules
