Learning how to repair a stereo receiver takes time and hands on experience. At times when the stereo receiver is not working, it is important to remember where you kept the stereo’s manual, that is, if you still have one around. However remember, there are some techniques to knowing what is wrong with the stereo receiver. You do not always need the manual just to learn how to repair the stereo receiver.
To repair a stereo receiver, you will need:
- Compressed Air
- New Fuses (if applicable) – can be purchased in electronic stores
- Philips Screwdriver
- Electronic Tape
- Check all the connections. First of all, make sure the wires are properly connected to the outlet, speakers, other hardware, and the receiver itself. By doing this, you should know if the wires are plugged into the right ports, input and output system. This first step on how to repair a stereo receiver may be basic but it’s sometimes overlooked.
- The fuses may be damaged already. If the stereo had so much power that it couldn’t contain, the fuses will be the first part that will burst, not the stereo. This is actually the role of the fuse. So if you think you’ve put up the volume too high that made the stereo damaged, check the fuses if they’re blown out. If this is the case, all you have to do is change the damaged fuses with new ones to make the stereo receiver work again. Use the Philips screwdriver to open the case around the fuses.
- Get rid of the dust. Sometimes, too much dust in the vents of the stereo receiver causes it not to work. When this happens, the dust blocks the heat from going out of the receiver and this results to overheating. The stereo may suddenly shut down because of this. Likewise, the lens of the CD player should be free from dust to prevent it from not working at all. Remember, dirty lens may not be able to read and play any CD. You can do this by just opening the CD tray and spraying some compressed air. Target the lens so that if it’s dirty, the dust can be blown away by the air. How to repair a stereo receiver may be as simple as this so it’s also vital to keep your stereo clean.
- Make sure that there’s no exposed wiring. Not only that this is crucial in “How to Repair a Stereo Receiver,” but it’s also precaution against possible accidents with loose or exposed wiring. Exposed wire that touches metal may lead the stereo not to function at all. But this can be easily solved by just taking off excess wire with scissors or by simply taping it to cover the wire.
- Assess the stereo’s noises. Damaged stereo may sometimes have some noises that could direct you to what the problem is. But in most cases, some audio interference in the radio involves a serious damage. In effect, it would be better to consult an electrician who can do it for you.
How to repair a stereo receiver may be simple at times that you can solve it by yourself. Don’t forget that it also doesn’t hurt to read the stereo’s manual. The steps above may help but if the problem is serious, it’s best to call for professional help from the stereo’s own service center, some electronic shops, or a professional electrician who can solve the problem for you.
