Your audio system will not be in a position to give out admirable sound if the amplification mechanism is faulty. An amp plays a very vital role in a given sound system where it raises an electrical signal to a level suitable for an output device such as a speaker or headsets. If you detect that your speaker is giving out a weaker sound than expected, then you are supposed to have the amp checked. Another situation where amplifier repair will be needed is when the output generated is distorted or 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.
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.
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.
The trouble shooting can proceed to the next stage if the power supply is corrected or is found to be in good condition. In this stage, all faulty elements in the rest of the system will be identified. The technician will employ a freezer in spraying the components with cold air. The system is switched on and the component that will go for long time still frozen before the system works is the spoiled 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.
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.
