My z-5500s are less than a year old, and i've got a strange problem. At random, the speakers will power off. They dont lose power totally, as the power light stays red. They wont turn back on until i flip the power switch on the sub off then on and press the button on the pod. I don't think this is a "lack of power" issue--i've tried them directly connected to the wall, over a power strip by themselves, and over a power strip with other devices and had the same results. Would this be worth contacting logitech and pursuing an exchange/some sort of service? Has anyone else seen this or a possible fix for this? Thanks..
