What is the reason why the Sony a7c screen flickers on and off?

1. Battery overheating: If the battery is overheated, the screen will flicker. This is because the temperature inside the camera is too high, which will affect the battery. A simple solution to this problem is to remove the battery, let it cool for a while, and then reinsert it for use.

2. Camera failure: If the above methods still cannot solve the problem of screen flickering, it is because the camera itself is malfunctioning. This is because the accessories inside the camera are damaged, causing the screen to flicker. The best way to solve this problem is to send the camera to Sony's official after-sales service center for repair, or contact professional repair personnel to handle it.
