Maintenance

Like any other electronic products, car LED screen not only needs to pay attention to the method

during use, but also needs to be maintained to make the screen last longer.

1 Cabinet

(1)The detection mainly includes the following procedure:

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)Other

Check the installation to ensure the safety.

2 Display Zone

Regular dust 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 screen by the particulate matter in the air or other chemical factors under humid

conditions.

The application and maintenance of LED car ceiling light screen 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. LED screen 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 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 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 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 other 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 splicing the screen at will .

(10).Non professionals 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

The storage place should be well protected from moisture the temperature should be

•

appropriate the relative humidity should be lower than 90

should be 10

should be 10 ~50

Avoid pests and rodents from damaging the screen and cables during storage

During storage rainwater or other corrosive liquids should be prevented from entering and

•

contacting the screen body modules etc

• Cleaning should be done well during storage to prevent debris or dust from accumulating on

the screen .emperature rises to the starting condition. If necessary, a heater can be installed.

(2)Use and storage of screens in special environment

The screens should be installed in places with accumulated water as far as possible.

The vehicle should be grounded for lightning protection, and the product should be used in a

thunderstorm environment to prevent lightning or screen leakage from burning out the screen

and even causing personal injury or death.

The screen installed in coastal areas should pay attention to the corrosion of the metal parts

due to the salt in the air.

The screen may not be able to start normally due to the low temperature in winter. You can

turn on the car air conditioner until the temperature rises to the starting condition. If

necessary, a heater can be installed.
