The car navigation display screen is black, how much does it cost to repair

By August 2021, ** is 300-500 yuan.

Due to the overheating of the central control screen, it is generally due to the installation of other additional equipment, such as navigation module, reversing camera, etc. The workload of the large central control screen exceeds its own design parameters, which triggers the overheating protection function. In this case, we can disconnect the additional equipment or reasonably increase the heat dissipation capacity.

Precautions for in-car navigation.

At the end of use, follow the shutdown sequence by closing the page, then shutting down, and finally unplugging. Some car owners are convenient, pull the plug directly after use, and never shut down, which is trouble-free, but it is easy to damage electronic components after a long time.

Portable navigation should not be exposed to the sun for a long time, the large temperature difference will not only affect the battery life of the navigation, but also affect the touch sensitivity of the LCD screen. It is best to put it away after use, and do not put it in a conspicuous position on the car, so as not to provoke thieves.

The car navigation screen and black screen can be repaired like this:

1. Please press the reset button or use a toothpick or needle to smash the reset hole to restart the vehicle.

2. There is no reset button or pinhole, you can force the power to shut down, unplug the power cord and the built-in battery, and plug in the power after a few minutes after replacing the battery.

3. If the problem is still there, it means that the components of the navigator are damaged. Original *** navigation, please find a local brand 4S shop for after-sales maintenance.

4. If it is a car navigation that is installed later, please find a shop or auto repair for you, if the store is no longer there, you can find a chain store.

The labor cost is estimated to be more expensive than the screen, showing that the dismantling machine is about 150 yuan, and the maintenance cost is about 100 yuan, totaling about 400 yuan. It is recommended to add some money to buy a new one, and there is after-sales service, which is more assured.

The solution to the black screen of the car display is as follows:

First of all, you need to turn the central control system off, turn it back on, and if that doesn't solve the problem, you need to turn the vehicle off and then turn it back on. If the problem still exists, you need to disassemble the central control system to check whether the power supply line and insurance behind it are damaged.

The vehicle display screen of the motor vehicle appears black, the motor vehicle needs to be parked in a safe position, and then the central control position is checked, and the method of investigation can be used to check in turn, and the specific cause of the fault is found to be repaired symptomatically, if there is no way to operate, you can contact the after-sales service or the maintenance factory to detect the central control screen.

Car display key grip

There are two kinds of on-board displays, one is placed on the bus, the first is the TV, in essence, the car TV, generally there are two ** inputs, one can be connected to the car with the car camera, the other is connected to the reversing image car camera, some also have MP5**** and Bluetooth function, can be used on the same kind of sports tools in the car display, convenient for use in the car sports draft liquid celebration.

Car TV is simply the mobile reception of digital TV (the difference between digital TV), mainly including set-top box, LCD screen, antenna, vehicle power supply embedded, etc. In order to facilitate installation and use, a variety of styles of car mobile TV products have been developed, such as desktop car TV, baffle car TV and top suction car TV, rearview mirror display, etc.

There are many reasons for the black screen of navigation, first of all, we need to check the reasons that may cause the black screen of navigation one by one, and solve the black screen according to the specific reasons.

1. Check whether there is electricity. If the navigator has no power, then the black screen is normal, so, we can press and hold the power button, after the boot screen appears, release the power button, if the display is off immediately, it means that the battery is dead, and charge it immediately.

2. Check the navigator software. There is also a situation, that is, to check whether the software of the navigator is genuine or pirated, if it is pirated software, there may be compatibility problems, so we need to reinstall the genuine software to solve the problem.

3. Judge whether it is caused by escalation. Sometimes, after the navigation is upgraded, there will be some problems, this is mainly because the original machine does not support the new version of the software, in such a situation, we need to contact the manufacturer, replace the navigation body to solve.

4. Whether it is normal to insist on contact. We can carefully check the wiring of the port of the navigator to see if it is when we are driving, due to the vibration of the vehicle, the line port is loose and falls off, if so, plug it in and it can be used normally.

5. Try pressing the reset button once. If there is a fault in the navigator, the easiest way is to reset it with one key, just at the output window of the navigator, there is a reset button, we can use a toothpick or a paper clip or something like a light poke, you can reset it for normal use.

6. The circuit board may be damaged. We can observe carefully, if there is a special situation during the use of the navigator, such as peculiar smell, etc., it may be that the built-in circuit board is damaged, then it is necessary to find a professional for repair and replacement.

7. The navigation monitor is damaged. There is also a possibility, that is, there is a problem with the display of the navigator, which is rare, but it is also necessary to carefully check and troubleshoot, just the computer first, the host may be fine, but there is a problem with the display, and a black screen will be displayed.

First of all, investigate and stabilize the power supply voltage of the car, and if it is stable, then the next suspect on the back of the machine, whether there is such a problem, it is recommended to replace the connection. If in contact, I also have no problem, should check the machine display cable, if there is a problem, replace the test with a new machine. Haven't had a similar problem before, replacing private car lanes.

If there is only no image and sound, it means that the power plug-in of the navigation display is loose; If there is no sound and no image, *** is broken.
