Hi,
I have a dB Opera 405D powered speaker, with the woofer dead. I have changed the 2 output mosfets ( IRFB4019 ) which are driving the woofer and gate driver ( IRS20957 ). The green signal LED indicates that there is signal present but there is no sound. When I connect the 2 woofer terminal to the woofer, I heard a "click" sound. Does it mean that the 2 mosfets and gate driver are OK, and the problem is with the audio processing components. Pls advice.
Thanks
Carlos
