Default JVC RX-508V

Hi,

A friend of mine brought to me the above mentioned amp for repair. When I switched on the wall socket, I noticed that the standby light is on but when I press the "ON" switch, nothing happens. By right when the switch is pressed then the amp would start up. Does it mean that the system controller IC is blown. Please advice.

Thanks

Carlos

Thanks, JonSnell, I will check and revert. I will need your expertise and guidance in fixing this problem as I am still fresh specially in amps using system controller ICs. I do not fully understand how the IC controls the power start up process. I will get back to you later some time on this.

Thanks

Carlos
