fflbrgst Posted October 29, 2018 Share Posted October 29, 2018 Never seen that issue before - if there's a problem with the preamp, the display usually shows a series of black boxes. If you use the up/down/left/right selection button and channel buttons, does the sound change? Unfortunately, it sounds like you would need to bring it to an authorize service center for evaluation.
