Hey Alain, Thanks for getting back to me. The amp is on my bench with no speakers or inputs connected. The final click never happens when I turn the amp on. The Blue Power led does not come on either. I did try different AC outlets with same results. This is the first time I have seen this issue. I did check the tracker circuit I did not find any shorts. I can not update the firmware because of this problem, amp is not detected. You said you seen Low Line on your bench before do you recall what the problem was. Any ideas would be greatly appreciated.
Thank You, Frank
