Open the power supply test of the mobile phone repair machine, and the startup current is normal. At this time, the display screen is also lit, which feels very strange. After connecting the battery, there is still vibration and no bright screen in the boot test. It was found that the battery cable seat was loose, so the battery cable seat was welded and the battery button was reinstalled. Press the power-on button again, the mobile phone can be turned on normally and enter the system, and the fault is solved perfectly.
