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.
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.
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.
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.
