When I turn on the unit, either via remote or the power button on the unit, you hear a clicking sound, but the unit does not power up.
@drrickc, check to see if you can still get your unit into diagnostics mode. Starting DIAG Press the “STANDBY/ON” key while simultaneously pressing those two keys of the main unit as indicated in the image below.
If it does not, you will have to open your amp up and check the fuses on the main board. Post some images of your logic board with your question so that we can point components out that you can check. For that use this guide
