My Reply: The power button works. The light is on. There is a waveform after the channel is connected to the 1KHz terminal. The twist control knobs are not working (all of them). Everything else seems to be working. Turning the system off an back on does not work. This is a brand new unit and it was working perfectly for about 20 hours. Now the control dials don't do anything. Could this be fixed with a factory reset? Is there a way to do a factory reset?
