THIS is what you have to DO to REVIEW any Electronic CARD EASILY

You have to DO THIS to REVIEW any Electronic CARD EASILY. In this basic electronics video tutorial we are going to see how we can check any electronic card since on many occasions we have cards for electronic devices or household appliances and we do not dare to check them for fear of further damaging the card or suffering an electric shock. Here I will teach you how to check it easily with a digital multimeter and the tool that we made in the channel to discharge the capacitors or electrolytic capacitors, the first thing we are going to check is the power cable, after that we will check the fuse, then the capacitor and the coil and if everything is fine we go to the rectifier bridge, I will also give you a TIP that we are going to apply to know if the hot ground of the source is in good condition, then we will check the main capacitor of the source that can remain loaded with a fairly high voltage and it is dangerous and the N-channel MOSFET switch transistor if everything is fine we go to the chopper transformer and the output voltages that we are going to measure in the electrolytic capacitors, we are also going to explain the failure of the card with problems in the optocoupler and if everything is fine now we go to the output voltages if you like the video do not forget to leave your LIKE thank you.
