You will not enjoy clear music if the amplification mechanism of your system is faulty as it will give poor output. The purpose of having an amp in a sound system is to raise the level of the signal to a point suitable for the output component which can be a loudspeaker or headset. If you are receiving a weak sound from your speaker, the problem is emanating from the amp and troubleshooting is supposed to be done. Amplifier repair will also be done in a situation where the sound received from the system is distorted or there is none at all.

Since amplification systems are constructed in a relatively simple manner, it is possible to identify the problem leading to the failure. A technician will follow certain steps at the time of executing the repair. The process begins with unplugging the faulty system and placing it on a suitable table.

A screwdriver is applied in loosening the side and top covers of the appliance. Once all components are visible, technicians normally look if there are components which are burned before they embark on sophisticated troubleshooting procedures. If the system had just failed, an odor will suggest that there is a burned component like a resistor or a transistor.

All power transistors in the system can be identified by use of the service manual obtained from the manufacturer. The power button is put on and a multimeter applied in determining if there is voltage on the pins of these transistors. The rest of the power ICs need to be identified and the same test done on them. The fuse will be tested for continuity and if found to be blown, replacement with a suitable one will be done.

Once the power supply is tested and found to be working, troubleshooting proceeds to the next stage. This involves finding out whether there is any component in the other sections that is faulty. A freezer is used to spray the components, one after another, with a short burst. The system is then put on and the component that is last frozen before the device begins to function is the faulty one.

When removing an element that is found to be spoiled, a heat gun is used to melt the solder holding it onto the board. After melting is achieved, a pliers is applied in pulling the pins from the PCB. It is required that you get the board out of its position so that you can access both sides. The holes left behind are cleaned with help of a solder wick.

The technician uses the manual to identify the component so that he replaces it with its equivalent. The position as well as orientation of the element should be maintained and the pins should always be straight. A side cutter is supposed to be used in trimming the excess pins once the solder has been applied.

Testing begins with fitting the circuit board back to its place after replacing the spoiled element. The appliance is plugged onto power supply and its power button put on. Once the repairer is convinced that the system is back to its normal working, he will put off the power and then fasten the covers.
