If your amplifier is not producing sound, it could be an issue with either the power supply or the output stages of the amp. It is essential to check that all connections are made correctly and securely, as loose wires can cause significant problems. Additionally, you should ensure that your unit is plugged in correctly and receives adequate power from a wall outlet. If these do not seem to be the problem, then it might be necessary to take your unit to a professional technician to assess and diagnose any further issues.
