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.
Normally, it is easy to troubleshoot amplification systems since most of them are constructed in a way that you can view all internal components and identify the faulty one. A number of steps are followed in accomplishing repair of an audio system. The first thing is to unplug the device from the wall and place it on a spacious table.
Screw driver is utilized in loosening the covers so that they can be removed. Complicated methods of troubleshooting are applied once the technician cannot identify any burnt component using his eyes. An odor will be noticed if there is a burned transistor and the system is opened immediately it stops operating.
With the help of the service manual provided to the consumer in the time of purchase, it is possible to identify all the power transistors. While the device is on, a multimeter is utilized in determining whether there is voltage on pins of these transistors. The repairer is supposed to look for the fuse and then check it for continuity upon finding it. A fuse with appropriate specifications is supposed to be used in replacing the one which has blown out.
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.
The component removed is identified and replaced with the appropriate one as stated in the service manual. Then new element is supposed to be soldered in the same orientation and position as the earlier one. The repairer should be keen that he does not apply too much solder such that the pins short.
Once replacing a spoiled component is finished, the board is fastened back to its position. The device is then plugged in and the power turned on. If the system is confirmed to be working as required, the power is put off and the covers replaced.
