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.
Most amplification systems are easy to troubleshoot as they are constructed such that it is possible to view all components once the covers are removed. Several steps are followed when undertaking repair for an audio system. The first one normally involves removing the device form its position and placing it on a table.
The covers of the device are removed through releasing the screws holding them in place. This enables the technician executing the task to be in a position to view all the components comprising the appliance. Before, sophisticated ways of troubleshooting are applied, the technician will use eyes to find out whether he can identify any burnt element.
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.
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.
A faulty element is removed using heat from a gun to melt the solder holding it in place. A needle nose pliers is the suitable tool to apply in puling the pins out of the board. Remove the screws holding the board in position so that you gain access of all sides. Cleaning of the holes left on the board is done through utilizing 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.
The circuit board can be fixed back to its position once the spoiled component is replaced. The power button of the device is switched on to test the system. After the system is found to be functional, the power is switched off and the casing replaced.
