What about the black screen of the camera?

If this is the case, there is something wrong with the CCD and the cable is loose or broken. The black screen at the moment is not necessarily that the camera is broken. You can check according to the following steps.

1. Try to replace it with a fully charged battery. Maybe your battery is low and your camera is not on.

2. Change the settings. Maybe you turned off the LCD screen when you took a picture last time, so the camera remembered. You can press the play button. If the camera can play back photos, the display screen is closed. Just change the settings.

3. If the above two attempts fail to solve the problem, then there may be something wrong with the display screen, and you should go to Canon camera maintenance department to check it.

Camera maintenance

1. Pay special attention to hold the camera tightly when using it. It is best to put the camera belt around your wrist or neck to prevent the camera from falling off your hand and breaking to the ground, and also to prevent other strong vibrations from affecting its performance.

2. Prevent taking photos under strong sunlight or other strong light sources for a long time. Although CCD and CMOS are relatively resistant to strong light and high temperature, attention should be paid to prevent burns or injuries. Under special circumstances, if strong sunlight or strong light source cannot be avoided, try to shorten the photographing time.

3. Stay away from strong magnetic and electric fields. Strong magnetic field or strong electric field will affect the normal operation of circuits in digital cameras, and even cause failures. So don't put the digital camera on TV, stereo, induction cooker and other electrical equipment with strong magnetic field and strong electric field.

4. Waterproof and moistureproof. When used in high temperature and high humidity environment, the lens is easy to be moldy and the circuit is easy to fail. If the camera is used in a humid environment or accidentally gets wet, it should be dried or blow-dried in time.

5. Smoke and dust prevention. Don't use it where there is a lot of smoke. If you have to use it in this environment, you should clean it up in time. Cover the lens cover in time when taking pictures.
