How to Tell If Your Charger Needs to Be Replaced

Every once in a while electronic devices suddenly ceases to function properly. Most likely,

a component is fried, or in other terms dead, when this happens. But sometimes there are damages that do not involve damaged electronic components. These damages usually involve de-soldered components or wires.

This kind of damage is completely repairable. It does not require you to buy anything to replace parts. However you will need a soldering pen, a desoldering pump(sometimes), and some lead. A voltmeter will also make the job easier. Of course, you can just borrow these equipment.

So how do you find out if a damaged charger requires a new electronic component or just some rewiring and re-soldering?

First thing you should know is that if your charger blew up (something popped), released some smoke, sparked (then stopped working). An electronic component was probably short circuited and is now dead. You then need to replace your charger.

Unless of course if you can find the damaged component and get a replacement, you can have it fixed. But this is very difficult and is not worth you time and efforts. It would be easier and cheaper to get a new one.

If not then you should begin with checking all connections. Make sure that your charger is properly plugged to the right outlet. After doing so try to move the ends of the wire. If your cellular phone suddenly starts charging, you've got a wiring problem.

If nothing happens, you can opt to disassemble your charger and check the input and output terminals for any signal using a volt meter. A signal is any electric response - voltage or current. You can also use a diode to check the output. If you don't get any voltage on the output end, a component is damaged. If there is nothing on the input end (the part of the circuit where wires from the plug go to), you have a wiring problem.

When you are fixing electronic devices, be sure to use extreme caution and care. You might damage something else and it would make fixing whatever you are fixing a lot harder. Also, be sure to use the right equipment and know how to use or operate them.

Note that you should also check if it is your cellular phone that is damaged. If you had tried multiple chargers on it and it still won't charge, there is an IC in your cellular phone that is damaged.
