If its just an LED that is deteriorating, etc. then it's not a big deal. But, if it's an indication that something more serious is gradually deteriorating, like power regulation on the circuit board, then it could mean that the unit is going to die soon. I haven't been able to find any information on the site on warranty and/or repair, and I'd hate to have to buy another whole new unit. I was hoping maybe there was a firmware fix that might compensate.
