This is what access support told me..............
Dear Hector,
The problem simply is that I can't tell what might have caused this in the first place.
Regarding the noise burst problem: this is a known issue and we're working on it. When this happens the TI emits a short noise and all LEDs go out for a moment. We try to fix this a.s.a.p.
Best wishes,
Joerg Huettner
