What s going on with a white screen in a car navigation display?

The current is unstable and needs to be powered off and restarted. The vehicle navigation system is mainly composed of two parts: the navigation host and the navigation display terminal. The built-in GPS antenna receives data from at least three of the 24 GPS satellites orbiting the Earth, which determines the car's current position.

Car Navigation Principle:Twenty-four GPS satellites orbit the Earth at an altitude of 12,000 kilometers above the ground in a 12-hour cycle, so that more than four satellites can be observed at any point on the ground at any time and at any time.

1. Program bugs: The white screen of car navigation may be caused by the bugs of the program itself, such as the instability of the program and insufficient memory. When this happens, delete some memory and restart the car navigation to reset it.

2. The power supply is not the same: the white screen of the car navigation may be caused by the replacement of the power supply, because the current is not the same, which will cause the white screen.

3. Hardware problems: The white screen of the car navigation may be because the screen is broken, the wiring is wrong, or the white screen caused by the IC and the motherboard, which is the most common phenomenon. If it is a hardware problem, you can only drive it to 4s for maintenance or go to a repair shop for maintenance.

4. Software problems: The white screen of the car navigation may be a white screen caused by the software upgrade or the version, if so, you can upgrade the software version.

Precautions: 1. When using on-board GPS navigation, it is best for our car owners to avoid the navigator close to radio waves or equipment with strong radiation, which may cause the navigator to malfunction, and it will lead to disordered star search and unstable signal for a long time.

2. When GPS positioning, before driving, do not start searching for signals before driving, and be sure to press the window slightly when searching, and it is best to stay away from high-rise buildings and other tall buildings when searching for stars.

3. When the owner cleans up the navigator, he can use toilet paper dipped in water or wet towel to wipe gently, do not clean directly with water, and do not put washing powder, detergent and other cleaning supplies to avoid the navigator being corroded.

Update the characteristics and principles of electronic components every day, electronic circuit analysis, actual home appliance maintenance cases, electronic DIY production working principles, maintenance ideas, maintenance skills cases, full of dry goods to share If you like it, pay attention to it, and everyone will discuss and learn together.

1. The charging voltage or current of the car does not match. Please try to replace the car charger, check that the output of the car charger is connected to the navigation machine, and see if the output voltage drops. If the pressure drop is severe, it means that the charging power of this car is too small.

2. Program bugs. The instability of the program itself is low on memory. The solution is to delete some memory and reboot the car navigation reset below.

3. Hardware problems. Maybe the screen is broken and there is a problem with the cables. Or a white screen caused by the IC and the motherboard. The solution is to come to the repair shop to check.

4. Software problems. The white screen may be caused by a software upgrade or version upgrade. The solution is to upgrade the software version.

Your evaluation is the greatest encouragement to us.

1. First of all, find out the cause of the white screen first, so as to solve the problem; 2. Then, due to the bugs of the program itself, such as the instability of the program and the lack of memory, etc. At this point, you need to delete some memory and restart the car navigation to reset it; 3. Furthermore, check the power supply to see if it is caused by the replacement of the power supply, because the current is not the same. The common causes of white screen are; Poor contact of the screen wire, fuse of the screen and failure of the screen circuit.

From what you said, you can see the icon clearly after turning it on, if the icon disappears instantly, the possibility of poor contact of the screen line is high. It can be tested after cleaning or changing the screen cable. If the image disappears slowly and the cursor is unresponsive, it is mostly a fault of the screen circuit.

If the screen fails, you can use a paper clip or toothpick or other fine hard object to poke the RST hole (reset button) to restore the machine to its original state.

Removing the car's battery live wire pile is the same as the reset mentioned above, note: generally remove the battery line live wire for 30 seconds to install it back. Through the above two methods, see if your navigation has returned to normal, if it is not normal, it is generally your touch screen cable or the contact in the screen is broken, when you change it, first remove the touch screen of *** navigation to see what model it is and then buy.

The center console of the car is located in the middle of the main driver's seat and the co-pilot's seat of the car, which is convenient for the main driver and co-pilot passengers, and mainly displays the content of ***, ***, GPS navigation, etc. Instead of using the traditional physical operation design of buttons and knobs, the capacitive touch type can be done with a light touch, press or swipe, just like the mobile phone screen.

The central control of the car is the place where the comfort and entertainment devices such as the air conditioning and audio of the car are controlled. The central control of the car includes the first control door lock system, and the driver can control the door switch and glass lifting system of the whole vehicle through the central control of the car. The control door lock system mainly has three functions: control, speed control and individual control.

The driver can control all the door lock switches, and at the same time, when the driving speed reaches a certain speed, the door is automatically locked, and there are independent switches for other doors, and they can control their own doors independently. The central control of the car also includes a console, a sound control panel and other vehicle controllers.

Summary. After the white screen appears, we can try to restart the vehicle system and see if it can be restored. If the screen of the vehicle continues to start after turning off, we can find the forced start of the car engine, and then, (in general) near the screen, it is a repair, and you need to poke it in with a toothpick) to restart the car machine.

As long as there is no problem with the hardware, restart the phone through this method to solve the white screen problem. Others can only be dealt with by a professional maintenance master.

Hello for reference only, I hope to help you, program failure, power mismatch, hardware failure and program vulnerabilities generally lead to a white screen in group noise navigation, as well as the difference in the power supply circuit Zheng voltage will lead to a vertical or white screen.

As long as there is no hardware problem, restart the hand core beam machine in this way to solve the white screen problem.

Others can only be dealt with by a professional maintenance master.

Summary. The reason for the white screen of car navigation is that the current is unstable, as well as the screen is broken, the cables, the IC and the motherboard, etc., and it may be that the memory is full or the memory is not enough to cause the navigation program error to cause the white screen.

What is the reason for the white screen of the car navigation.

The reason for the white screen of car navigation is that the current is unstable, as well as the screen is broken, the cables, the IC and the motherboard, etc., and it may be that the memory is full or the memory is not enough to cause the navigation program error to cause the white screen.

The main solutions are: first of all, you can need to power off and restart, if not, you can delete some unimportant content, and finally you can go to the 4S store to upgrade the navigation board again.
