Hi, I wanted to change my power cord this evening on my 4B3 amplifier. I followed the owner manual steps Before plugging in the power cord, make sure the Master Circuit Breaker is switched to the ‘ON’ position. Plug
the IEC-320 C14 end of the power cord into the amplifier, then plug the other end into an approved and grounded A/C receptacle. The STATUS LED should flash green, then switch to red indicating A/C power is present in the unit.).
When I pressed the power on button in front, nothing happen. Any suggestion?
