Why is there no sound on the acoustics of the Microlab FC-330?
Acoustics itself works, it turns on but does not produce sound when a sound source is connected to any one. From the speakers, there were no amplifiers on the TDA 2030a board that were installed before that but there was no sound anyway, what else could be the reason?
Hello! Are the circuit boards and wires intact? Perhaps the reason is this! It is also worth checking the binding of the chip. And in general, does food come to her? You can try to touch the signal output of the chip when the acoustics are turned on, if there are noises, look for a malfunction in the input circuit.
