Attention! Guidelines for Packaging Violations of Printed Circuit Board Components!
For this, the circuit board can be removed and cleaned with industrial alcohol. Be careful! Guidelines for Packaging Violations of Printed Circuit Board Components.
The production process of printed circuit boards, connectors, sockets, plugs, toggle, plugs, sockets, and terminal blocks involves the following processes.
Realize the connection and disconnection between the reverse distribution box, main junction box, soft starter, encoder, frequency converter, DC speed regulator, series connection, resistive load and frequency converter, AC frequency converter, and high-voltage electrical appliances, and achieve the soft start or speed regulation function of the DC motor.
The following equipment circuit boards do not provide power. It is necessary to check whether the power supply to the circuit board is connected, whether the power circuit used is open, and whether the power output of the power circuit board used is correct.
The following equipment circuit boards do not provide power. Is the power circuit used open circuit? The power input and output of the power circuit board used are in a disconnected or disconnected switch state.
Some circuit boards have not been powered on. Is the power output of the used power circuit board open or disconnected.
Firstly, you can open the power interface to see if there is a fuse burning on the power supply, such as a fuse burning out or a rectifier bridge burning out. If the fuse is burnt out, please restore the power supply on your own.
Step 3: Check the grounding condition of the internal machine casing, and use the 12V input power supply as an example to determine the power wiring.
Step 4: Check if the power connection is damaged, and use a 12V multimeter to check for any connection faults that need attention.
If the power supply is normal, but the LED display light is not on, it may indicate that the motherboard has received an abnormal signal with a malfunction and needs to be replaced.
If the power supply is normal, check if there is a short circuit in the power connection, unplug the power plug, and troubleshoot.
The above are the knowledge points introduced by the editor about the brightness of LED display screens, hoping to be helpful to you.
