Better late than never I guess but after ar least a moth of trouble free operation, and having to buy another DAC out of complete panic and disarray, I just had to share this... This could help
others. Anyway, I had the same problem. I am an electrician with training in electronics as well. I succeeded in fixing mine by unplugging and isolating (making sure the ribbon contacts don't touch anything the're not supposed to) the front display from the main board inside the unit (carefull it's a usual ribbon cable with not much play) and then plugging it into my compuyer with all the Topping upgrade steps and it worked. After the upgrade is done, turn off the unit, unplug it from the computer and from the 120v outlet and reattach the ribbon cable. Turn on and enjoy ! I believe it's a frequent routine problem and Topping still wanted me to send them the unit for diagnostic. Not good enough for me.
