Matsutec Active Speaker System Repaired
A customer brought this Matsutec Active Speaker System for repair with the complaint of no power/no sound.
Once the cover was removed I could clearly see the burnt area on the circuit board.
I had to remove the bad parts and test all the corresponding parts and had to clean the area with chemical.
There are couple of transistors and resistors that were burnt and shorted. If you wish to learn how to test electronic components, you can check out this website
Once the replacement are fitted in and powered it On, this speaker system came back to life again.
