Summary. Hello: There are two reasons for the black screen 1. In the digital camera, there is a liquid crystal screen brightness control power supply circuit, when the circuit is damaged, there will be a fault that the screen does not light up (black screen).

This glitch only affects the screen display, so "put it on the computer, and you can display the image again". 2. If there is a problem with the connection cable of the LCD screen, it will also affect the screen display, but it is generally a local black horizontal bar, vertical bar, etc., and the probability of the entire black screen is very low. Since digital cameras are mechatronics equipment, they are very expensive and squeamish, so they should be repaired by professionals.

Hello, landlord, if the phone camera can't take pictures now, and it's a black screen state. It is recommended that you restart your phone to try it, because sometimes the system is abnormal, including the camera program. There is a possibility that such a situation will occur, and in general, restarting the phone can solve it.

If you restart your phone, the camera is in a black screen. In addition to the bug, you need to find the app management in your phone's settings, and then find the camera program to clear the camera's data settings. In this case, the camera can also be restored to its factory condition.

If you have the option to reset in your camera settings, you can also go to the camera's settings, find the reset option, and reset the camera to see if it can be solved.

You can also find the option to manage permissions in the phone settings, and check if the camera has permission to call the camera? If the permission is turned off, turn it on. After opening it, test the town of the blind again to see if it works.

If the landlord still can't solve the problem after trying the above steps, it is recommended that you can back up the important data in your mobile phone. For example, some multi**files are disgusting,**,** and the like, including your contacts, and then try to restore the phone to factory settings. Because a factory reset will restore the camera including the mobile phone system to its factory state, if it is some software incompatibility or system problems, it can be solved by restoring factory settings.

If the landlord's mobile phone still doesn't work after the factory reset, then it can't be ruled out that the camera's hardware is faulty. You can go to the after-sales service to detect whether the relevant hardware is abnormal.

Summary. 1.Low power or poor battery contact.

Check that the battery is fully charged, or try using a new battery; Check that the battery is in good contact. 2.The camera goes into sleep mode.

Press the shutter button or other key to wake up the camera. 3.The lens cap is not opened.

Check that the camera lens cap is open. 4.Camera malfunction.

It may be that the camera is not working properly due to a hardware failure and needs to be sent for repair.

I haven't used this camera for several years since I bought it, and the screen goes black as soon as it is fully charged.

Hello dear, based on the question you asked, I suggest that you can try the following methods to solve the problem first:

1.Low power or poor battery contact. Check that the battery is fully charged, or try using a new battery; Check whether the contact of the electric shield is good.

2.The camera goes into sleep mode. Press the shutter button or other key to wake up the camera.

3.The lens cap is not opened. Check that the camera lens cap is open.

4.Camera malfunction and correction. It may be that the hardware failure causes the camera to fail to work normally and needs to be sent for repair.

If it hasn't been used for several years, the battery may be aging and can't be charged properly. In addition, it is possible that the memory card is also coded and the letter is damaged or badly damaged and does not work properly. You can try to change the memory card.

You can go to your local electric tardination wheel product store or buy a new memory card online.

It could also be because the camera connector is damaged. You need to search Liangzhou to check whether the camera interface is dirty or loose. If so, you need to clean the interface or revisit the new connection.

If none of the above steps solve the Q&A question, you can try resetting the camera. In the camera settings menu, look for Wang Co to the "Factory Reset" option, restore He Lingyu camera to factory settings, and reset the camera.

Now the key is the black screen and you can't find the reset camera.

Dear, I suggest you try to turn on and off the machine a few more times, although this method is very old-fashioned, but this can solve most of the digital camera problems.
