Signs You Need Amplifier Repair Services

By Harriett Crosby


Amplifiers are electronic devices that are commonly used in audio equipment such as home theater systems and car sound system to amplify the amplitude of input signals that are passed through them. They are classified into three groups namely: transresistance, transconductance, voltage and current amps. Continued use of these electronic devices for a long time will cause them wear and tear gradually to the point where amplifier repair services become inevitable. Whether it is repairing or replacing you need, is determined by the extent of the problem.

There are quite a few numbers of issues that you will be faced with from time to time. This should not worry you as it is common for any device to develop problems in their functioning after having being used for a longer time. When this happens to you, it is important that you diagnose the problem first before you moving to the nearby electronic shop for repair. This way, you will be able to save yourself a lot of money.

Amps that are used in home theater systems and audio systems should be maintained and serviced regularly. This way, you will be able to identify any issue in advance before it develops into a big, costly problem. However, that does not mean that other amplifiers do not require maintenance and servicing; they too need. How you carry out preventative maintenance on your devices will go a long way into determining the functionality of your amps so it is of utmost importance.

Some of the most common failures experienced with amplifiers include the device not responding at all. You can try troubleshooting this problem by removing all the wiring of the speaker as well as other power supply connections and reconnect them again. This can help remove any minor problem if any though it might not be a lasting solution. However if that does not work at all, then your amp is faulty.

If your amp keeps turning on and off when it becomes hot, then chances are that it has a problem with gain sensitivity. You probably bought a counterfeit power transistor which is causing inadequate power sinking. If you are not sure what need to be done with such a problem, just leave it to professionals.

Overheated amps tend to lower the sound of the system. Installing a cooling fan will help in solving this problem. However if the sound persists being low if after installing the fan, then further diagnosis of the system is required. An electrician should perform this. In case of a burned out fuse, it should be replaced as soon as possible; have a professional check for any shorted output or driver transistors.

The first step that you should take when it comes to repairing is checking if the amp is under warranty. If it is, do not break the seal but send it to the manufacturer to have it repaired there. Normally, the manufacturer will refuse to accept a device whose warranty seal has been broken.

Amplifier repair involves electrical work. As you know, electrical work involves a lot of risks and therefore you should leave this work to professionals, preferably the manufacturer. By trying doing this work on your own, you might end up causing more harm than good.
