Hi everyone, I recently got my GL2400-32 stop working. It just stop working with a mild pop sound in between playing. From what I observe the whole master section (the middle part with Aux and LR) has no battery (no LED indicator can be turned on except the Phone out). In the channel section they are having mute light on but not there is never a signal (or I do not know as the LED's does not light on). What could be the problem? Thanks all!!!
