VDC1VDC1will be zero and a large voltage will be directly applied to D3. The excessive forward current may force the D3 to fail open. The transformer and the shorted diode (D1) are the two other components that are likely
This post is going to be a more on the technical side, but hopefully will be easy to follow. What it will cover is how to troubleshoot why a power rail is just not right on your PCB assembly. It will focus on the DC/DC converter chip, since that is a common power supply component...
For beginners, they must have knowledge of electronic components & their working to troubleshoot any circuit or project. Similarly, having good knowledge of how to test different components is also one of the troubleshooting skills. To avoid undesired results, it is advisable for beginners to test...

Therefore, if the diode is not working, your microwave will not be able to heat. As with the magnetron, this part requires electrical knowledge, which means you should contact a professional. IS THERE A RESET BUTTON ON A MICROWAVE? Most microwaves do not come with a reset button. However,...
To troubleshoot the power supply, first, measure the rail voltages. The multimeter readings should reflect the input and output values expected at the component. There may be some problems in the circuit when there is a variation in voltage. For example, when the readings display 0 volts, the...
The following article provides information about how to troubleshoot and resolve a startup problem on a Dell Chromebook 3110 and 3120 2-in-1 or Laptop.
Finally, you should measure the current draw of each LED strip to ensure it does not exceed 1.5 A per 30 LEDs. With these steps in mind, you can safely test and troubleshoot an LED display for your project. Planning For Maintenance And Replacement Parts The key to the successful operation...
2. Turn digital multimeter dial to resistance, or ohms, which often shares a spot on the dial with one or more other test/measurement modes (continuity, capacitance or diode; see illustration below). The display should show OLΩ because, in Resistance mode, even before test leads are conne...
Continuity is a great way to test if two SMD pins are touching. If your eyes can't see it, the multimeter is usually a great second testing resource. When a system is not working, continuity is one more thing to help troubleshoot the system. Here are the steps to take: ...
