In a situation where the amplification mechanism is faulty, then your sound system is likely to give a poor output. The work of an amp is to raise the level of an electrical signal to a level that can be fed to the targeted output device which can be a speaker or a headset. This means if the speaker is producing a weak sound, the problem can be traced back to the amp and correction made. Amplifier repair may be required also if the output is distorted or it is not clear.
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.
Use the service manual provided by the manufacturer to identify the power transistors. While the power is on, a multimeter is used to check whether there is voltage in the pins of the transistors composing the device. The same should be done for all power ICs identified. The repairer will look for the fuse and test it for continuity.
Troubleshooting can proceed to other parts of the device if its power supply is fixed. A freezer will be used to look for presence of faulty components in the system. What happens is that all components are given a short burst and then the power put on. The last element to clear moisture is the one which is damaged.
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.
Through use of the manual, it is possible to identify the component that is not working. A new one is then acquired and soldered at the same position and orientation. While inserting the pins of the element into the holes, one should be careful so that he does not bend them. Only enough solder should be applied so that the pins are not short. A side cutter is applied in clipping off the excess pins so that they do not protrude from the underside of the circuit board.
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.
