How To Solve SUBWOOFER Active Speaker Problem
Thank you for visiting the channel
In this video, my activity will be repairing my parents' Polytron brand Subwoofer Speaker.
The damage that occurs is when the power is turned ON, and the sound is there and then suddenly turns off.
Replacement components that I do is to replace the IC STA540 components.
You can download the Datasheet for IC ST540
