Many novice radio amateurs are afraid to take on the repair of equipment such as computers, players or stereos and take them to service centers in the event of a breakdown. But in fact, it is not so difficult to repair the music center yourself. With basic knowledge of radio mechanics and skills in working with tools, such repairs will not be difficult.
Instructions
Step 1
Find out the reason for the malfunction of the music center. The most frequent and obvious breakdowns can be associated with a violation of its parameters or the absence of sound as such. Check the speakers (speakers) with a tester for voltage.
Step 2
Use a functional speaker from another technique to make sure the sound is not in the center. If, after connecting working speakers, there is still no sound, there is a problem with the music device itself.
Step 3
Disassemble the case of the music center. To do this, unscrew all fixing screws with a Phillips screwdriver and remove the rear protective cover of the device. This will take you to the main board and can inspect it.
Step 4
Inspect the connection of the input connector and copper contact tracks on the main board of the music center. Use a soldering iron to restore the soldering in those places where it is damaged. To do this, it is better to use low-temperature solders that melt at 100 degrees, or generally conductive glue, so as not to violate the integrity of the small parts of the board.
Step 5
Play the music center in all possible modes (radio, cassette tapes, MP3 player) and check for violations. If in all modes the sound is reproduced with the same interference, then the matter is in the amplification output path. Breakdown in the power amplifier. To fix it, replace the damaged amplifier microcircuit with a working one.
Step 6
After troubleshooting, carefully inspect the main board again. It may have poorly soldered places, swollen capacitors, darkened tracks and other defects that may soon make themselves felt. Replace all "suspicious" parts. Thus, you will prevent another breakdown of your music center and extend the life of your equipment.
