Hi Nikos
I am sorry you are having problems. My guess is that this is not a new unit (we have been aware of the U106 problem for a long time, and this part is now directly soldered to the board which solves the problem).
If I am correct, you should discuss this with the person from whom you bought it.
If I am incorrect, I apologize, and you should immediately return it to your dealer for a warranty claim.
