As an important multimedia terminal in the modern information age, the outdoor LCD advertising machine uses multimedia materials such as text, pictures, videos and small plug-ins for advertising, which is closely related to our life. And most of the common advertising machines in our lives are LCD advertising machines, so how to maintain the LCD advertising machine display?
1. How to clean the shell
Use a cotton cloth dipped in water to wipe, do not use any detergent, which will make the shell lose its unique luster when it leaves the factory.
When the LCD is switched on and off, there will be interference patterns on the screen, which is caused by the signal interference of the display card, which is a normal phenomenon. This problem can be solved by adjusting the phase automatically or manually.
2. How to clean the LCD screen
When cleaning the LCD screen, try not to use a damp cloth with too much moisture, so as to avoid moisture entering the screen and causing faults such as short circuit inside the LCD. It is recommended to use soft objects such as glasses cloth and lens paper to wipe the LCD screen, so as to prevent moisture from entering the LCD and not scratch the screen.
3. Matters needing attention
Before cleaning the screen of this machine, please unplug the power cord to ensure that the advertising machine is in a power-off state, and then gently dust off the dust with a clean and soft cloth without lint. Do not use spray directly on the screen.
Do not expose the product to rain or sunlight, so as not to affect the normal use of the product.
Please do not block the ventilation holes and audio sound holes on the advertising machine shell, and do not place the advertising machine near radiators, heat sources or any other equipment that may affect normal ventilation.
Do not disassemble or repair the advertising machine by yourself to avoid high-voltage electric shock or other dangers. If you need to repair, you should ask professional maintenance personnel to complete all maintenance work.
Since most of the advertising machines are used in public places, the voltage is unstable, which may cause damage to the advertising machine equipment. It is recommended to use stable mains power, and must not use the same power supply with high-power equipment such as elevators. For example, in places where the voltage is often unstable, such as subway stations, please be sure to use the corresponding voltage stabilizing equipment for voltage regulation, otherwise it will easily cause the advertising machine to work erratically and even burn out the advertising machine.
When inserting the card, if it cannot be inserted, please do not insert it hard, so as not to damage the card pins. At this point, check whether the card is inserted backwards. In addition, please do not insert or remove the card in the power-on state, it should be done after the power-off.
