Hello, I have a serious problem with a Pod X3 Live unit, one day it started to turn off on it's own and restarting. The next day it didn't even turn on. Only the leds of the words"DRIVE" "BASS" "MID", etc. I tried with another power adapter and nothing changes. I opened the unit and nothing seems wrong (It is out of warranty). There is an authorized service center in a city four ours a drive, and 6 hours by bus. I can send it there. But it would be really helpful to have an idea of what is the problem with te device Any clues?
