What causes electronic components to fail?
Electronic components have a wide range of failure modes. Failures can be caused by excess temperature, excess current or voltage, ionizing radiation, mechanical shock, stress or impact, and many other causes.
How do you troubleshoot electronic components in the circuit?
Do You Recognize the 8 Techniques to Troubleshoot Your Electronics Circuit?
- Confirm the Problem in the Circuit.
- Consider Visual Inspection First.
- Select Troubleshooting Tools.
- Power up the Circuit.
- Check the Power Supply Block.
- Check the Individual Components.
- Check the Main Controller.
- Check the Loads by Metered Power Supply.
Why does my computer not start when I turn it on?
Video Card or RAM Failure. Sometimes the power surge damages additional components or passes through the power supply harmlessly and short circuits other electronic cards. If, with the computer open, you switch it on and see lights on the motherboard or hear drives operating, the power supply is probably not damaged and the motherboard is working.
Why does my car not start when I Turn on the radio?
If your car won’t start, but lights come on, and the radio is turning on, it could be a few different problems. The most likely culprit for this issue usually deals with the battery.
What does it mean when your car won’t start?
If the battery does not pass a load test, then this means the battery needs to be charged. If it can gain a charge from another battery and the vehicle can start after getting a jump, you have fixed it. However, if it doesn’t start, a damaged fuse might be the problem, a broken ignition switch, or a bad starter.
What causes a computer to not start up after a lightning storm?
Voltage surges in the power supply can cause insulation break-down that keeps various parts from working. Lightning storms often cause especially-high voltage surges that can pass through many surge protectors and cause short circuits in your computer. The key is to figure out what part is damaged and replace it.
What does it mean when Your starter won’t start?
When this occurs, it means the starter is not engaging with the flywheel. This is a worrying situation, which could result in having to replace the whole component. If you try to start your engine and the engine doesn’t start instantly, you may have to try again.
What causes a Mercedes Benz to not start?
Damage, neglect, or even ordinary wear and tear in any of the parts named above can jam your Mercedes’ ignition, rendering it impossible to start the car.

How to troubleshoot a computer that won’t start up?
Unplug everything before opening the computer case, and then unplug the connectors and note where they were connected. Unscrew the four power supply screws from outside the case and remove the power supply unit. Get an exact replacement from a local computer supply store and install it. If that was the only fault, the computer will start normally.
What happens when you discontinue power to the starter?
When you start the engine and release the key the circuit will, discontinue the power to the starting motor. If this stays on after the engine has started, the main contacts in the solenoid, have most likely failed. This will ultimately cause serious damage, to the whole starting system and the transmission flywheel.
