1. The circuit board is not energized, it may be that the components in the circuit board are soldered or unsoldered, resulting in no electricity.
2. For the situation that the circuit board is not energized, there may be a problem with the resistance of the circuit board, or a problem with some other components that causes this to happen.
How to detect if the circuit board is not powered on
The solution to the circuit board is not powered on: In the case that the circuit board is not powered on, we can first use a multimeter to check the circuit in the circuit board to see if the circuit is disconnected, and then continue to test. When replacing the circuit board, do not directly replace the good circuit board. Before replacing the circuit board, it is necessary to determine whether there is a short circuit in the circuit board test panel. If there is a short circuit, it cannot be replaced directly, otherwise the replaced circuit board will be burned out immediately.
