Occasional, soft "tick" sound from back of set
Anyone ever notice an occasional, soft "tick" sound coming from the back of the KDL-55W900A, when the set is turned off? I am guessing it's nothing serious--perhaps checking for a software update, checking the Internet connectivity, pushing out cookie data to Sony, or something similar? It doesn't happen too often, maybe once or twice daily (I have yet to sit silently in front of the screen 24 hours, to see exactly how often it makes the noise lol). I'm mainly just curious why it makes that "tick." On the whole...still 99% satisfied with this beautiful set. (The 1% unsatisfied is due to the partially-functional NHL GameCenter LIVE app, which isn't streaming live hockey at present...I hope Sony's working on a fix.) Thanks!
