Hey, my z5500 was working ok today, i decided to move the thing, so put the sub on my bed whilst i sorted all the wires out and put them back neatly, got it all set up properly, turned it on, and then what?..., no sound coming from left or right front speakers, i tried the speakers in a diffo channel like rear right and left, and they work, so tells me front left and front right channel has gone, next it got even worse!, heard a wooooing noise getting louder, then pop, stopped, 40bars lit on control center, control center crashed, just odne it now, pop and 40 bars on the control center, no sound, gotta turn the speakers off by the switch on the sub, keeps doing it, i dunno whats happening, should i ring logitech up, there email support aint no good?, will they just send me a replacement or will they need the sub sending back?
