Miguels, a while back I had an issue with my DSJ though not to the extent you mention. In my instance I tried rebooting (turning off then on from the rear mounted switch) without success. I tried it again but before turning the unit back on I unplugged it from the outlet and left for 5 minutes or so before reconnecting and turning back on. In that instance it worked and I haven’t had a hiccup since. Not sure if that was the solution or not but worth a try.
