If you have ever used tools before then chances are that you can remedy many common problems that occur with electronic equipment. Don’t worry, you don’t have to have a degree in electrical engineering. Many problems are easy to spot and remedy. I will list some of these issues that frequently occur with audio equipment and show you how to resolve them.
The power supply is probably one of the most common issues with audio equipment. Oftentimes the power cable is not properly plugged in. This can occur if you move the equipment and the power plug does not fit very snug. To figure out whether there’s a power issue, check whether the audio equipment has any lights or indicators which are active. If none of these indicators are active, chances are there is no power. Next, make sure that you have turned on the device.
If the device is turned on by still doesn’t have any active indicators, double check the power cord. Make sure it is plugged in firmly. Also, make sure that if you use a power strip that the power strip has power. Many power strips have a small light that will be eliminated when there is a voltage. Next, check if the fuse which is located near the power cord on the device is okay. Some devices require you to pull the small list that contains the fuse. Either use a voltmeter to check with the fuse is still okay or visually inspected. A blown fuse will have a wire which is melted.
If the fuse is blown, replace it with an identical fuse. Then test again. If the second fuse blows then the device is faulty and needs to be taken to a repair center.
I generally do not recommend that you open any device which connects to the mains voltage. This can turn out to be a safety hazard. But if you do open the device then make sure that you have unplugged the power cord.
