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.
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.
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.
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.
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.
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 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.
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.
