Check whether the power supply works normally and whether the power cord is loose.(1)The detection mainly includes the following procedure: 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.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.1Cabinet.(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.(2).Do not use it as much as possible under harsh natural conditions. Such as strong thunder and lightning weather.(1).The power supply system is required to be stable and well protected.(s2)OtherRegular 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.(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.(.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).Itisrecommendedthatthescreenrestformorethan2hoursadayandthescreenshould , beusedatleastonceaweekduringtherainyseasonGenerallythescreenisturnedonat . , leastonceamonthanditislitformorethan2hours , .Check the installation to ensure the safety. 2Display Zone.The application and maintenance of LED car ceiling light screen should pay attention to the following issues:/ /07 The screens should be installed in places with accumulated water as far as possible. The screen installed in coastal areas should pay attention to the corrosion of the metal parts due to the salt in the air.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 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.

(5).How to replace the IC cardRemove the IC, Clamp the IC both ends with tweezers so that each pin is aligned with the corresponding pin position on the pad.Note the IC direction.After module lights up and the display effect is normal, assemble the module back into the cabinet. Use single component RTV silicone rubber (black) to patch in the rubber where it has been scraped off and around the lamp board of the module which copper sheet is off.Accurately corresponds and appress to the IC pad.(Note that the pin at the concave dot in the upper left corner of the IC front side is the first pin and must be welded corresponding to the small circle of the circuit board IC silkscreen).Clean the conformal and tin freezing point on the pad surface.Use soldering iron to drag the pins on both sides of the heating IC back and forth. Fuse the tin on the pad with the pin and fix it onto the pad.Tilt the lamp board to 45 degreesHeat the tin on the IC pin with a soldering iron, drag it from up to down and gently shake off any excess tin sticking to the soldering iron.Until all the IC pins are not connected.Heat the IC with a air pressure gun(390℃) until the pin tin surface melts, then use tweezers to pick up the IC.Clean the conformal coating on the pad surfaceUse air pressure gun to heat the bad ICRemove the bad ICClean the tin freezing point on the pad surfaceAlign the IC with the direction and the padAdd tin to fix IC pinClean up excess tin from IC pinsShould not have connected ICOpertion schematic diagram?/ /11
(6).How to replace the LEDsHow to measure LEDs?Aim the air pressure gun at the bad LEDs and heat until the tin surface of the pad melts.Heat the LEDs with the air pressure gun. Note that the temperature of it is set to 200℃.Take out the LEDs of the same model as the product, measure and confirm the positive and negative poles of it according to the above Remove the bad LEDs with tweezers and set aside.Set the digimer to diode test, the red stylus touches any pin on the side of the LEDs and the black stylus touches the pin on the other side of the LEDs. If the LEDs is lit, the end of the red stylus contact is positive, the end of the black stylus contact is negative.If the LEDs is not bright, switch the red and black stylus and measure again. If it is still not bright, means that the LEDs is broken. of other LEDs.Observe the LEDs front four corners which have a very small unfilled corner, a lamp base of its bottom is the positive of LEDs and the remaining three anti-clockwise lamp bases are respectively the negative pole of red, green,and blue lamp. The most direct method is to observe the silk screen printing of "+, R, G, B" on LED light board or the unfilled corner directionHow to replace LEDs?①②Heat the LEDs pad with air pressure gun and place the LEDs in the corresponding position on the pad. Heat until tin surface of pad melts and fixed with air gun.(LEDscannot float high and tilt)It can working properly after module is bright and display effect is normal.Clamp the LEDs with tweezers and make every lamp base accurately corresponds and appress to the pad.Heat the LEDs with the air pressure gun (200℃)Remove bad LEDs with air pressure gunAlign the LEDs to the direction and the padHeat until the LEDs pad is melted and fixedUnfilled cornerPositive

?/ /12 The temperature of the soldering iron should be 350℃ when replace IC and LEDs. The welding should be quick and the welding time should not be too long. Otherwise, IC and LEDs may be damaged due to overheating.Be careful when operating the product to avoid being scalded by the soldering iron. Turn off the soldering iron power in time when not in use. keep it away from combustible and let it cool down naturally.Non-professional and technical personnel please do not try to repair the LED module without authorization. Send the module back to our company for maintenance.Do not use sharp tools when removing the lamp board of waterproof module, otherwise the circuit board line will be damaged.This measurement method is only applicable to LEDs of this product model.Note: Warning：
