How to TEST a DIODE Bridge to KNOW if it is GOOD / gbu406, pbl405. gbu4m. In this basic electronics video tutorial we are going to analyze the diode rectifier bridge in different electronic boards from LCD TV or LED TV sources, remember that the diode rectifier bridge works with the 220/230v home network voltage and is very dangerous A minimum knowledge of both electricity and electronics is recommended since high voltage is handled in the electronic cards and can give us a good electric shock. The ideal is to discharge the electrolytic capacitors from the power supply since they can remain charged with a fairly high voltage, let's see where we can find it on the electronic card or PCB, the screen printing that comes on the board, the main failures or failures caused by a diode bridge rectifier or diode bridge in poor condition since it is responsible for many breakdowns in practically any electrical, electronic or household appliance, such as measuring it on a plate with a multimeter digital meter or TESTER how to measure it outside the board or electronic card also with the digital multimeter or TESTER how to identify it in an electrical diagram, and at the end of the video I leave you a TIP to know if you have the diode rectifier bridge in good condition, and not Only the diode rectifier bridge, if not all the elements before the bridge, such as coils, electrolytic capacitors, protection elements such as varistor, thermistor, relay, fuse, etc. If you like the video, don't forget to leave your like, thanks.
