I am a tech and have been in this industry for almost 20 years. I decided to update my arcam 390 and update locked up and I waited 24 hours before I tried anything. It stopped on net please wait.... I tried pressing buttons on the front but to no luck. So I turned off and factory reset per instructions. No sound out of anything. Any help or ideas I would be open for. We aren’t arcam dealers but I love the sound of this product. Thanks in advance.
