A USB video device refers to a device that can transmit sound and images to a computer through a USB interface. Common USB video devices include cameras, video capture cards, etc., which are widely used in video chat, live broadcast, photography and other fields. However, during use, we may encounter such a problem: the video screen suddenly turns black and flashes, sometimes causing the device to completely fail. So, why does the USB video device have a black screen problem, and how can we solve it?
There are many reasons for the black screen of USB video devices. Here are some common situations:
1. Device driver problems: The device driver is out of date or incompatible, or the driver is invalid due to system updates, which may cause the device to fail to operate normally.
2. USB port connection problem: If the USB port is loose or defective, the device will not be able to connect properly, resulting in a black screen.
3. Abnormal data transmission: A large amount of data is transmitted or data is abnormal, which will cause the transmission to fail, causing the device to suddenly go black.
4. Software or plug-ins that affect the device: Conflicts or incorrect use of some software or browser plug-ins can also cause a black screen on the device.
5. Hardware problems of the device itself: Device hardware failure may also be one of the reasons for the black screen, such as the device being broken, the circuit being disconnected, or problems with the photoelectric components, etc.
For different situations, we need to adopt different solutions:
1. Update or install the driver: You can download the security version of the driver from Device Security or use the driver assistant to update.
2. Change the USB port: Change the device to another USB port and plug it in to see if the problem can be solved.
3. Data transmission is normal: Replug and unplug the device, check the data cable, and clear cache and temporary files in a timely manner.
4. Close the conflicting program: Close the conflicting program or plug-in and restart the system.
5. Send for repair or replacement: If the above methods do not solve the problem, then it is likely to be a hardware problem with the device itself, and the device needs to be sent for repair or replacement.
