After about four years, my Vizio VSB210WS is giving me the thermal shutdown error. I just noticed it last night while visiting friends. Every few minutes the LED lights on the soundbar would light up with the fourth one flashing, which the manual indicates as the thermal shutdown error. But after just a few minutes it would deliver audio. However, it just repeats this cycle every few minutes (5 or less). My wife and I were not even home watching TV or anything yesterday and it's winter so the house is around 69 degrees. The soundbar sits on the top of an entertainment cabinet with no sides and it is half a foot or so from the wall, so ventilation is very good; better than when I actually had it mounted to the wall. The thing is that since my TV's speakers suck so bad I have used it for audio 24/7. The unit is always on, whereas before I got this TV I would only turn it on when watching movies since my old HDTV's speakers were adequate for most viewing. I wonder if it just hit that magic number of hours of operation it was built for and it had a meltdown? I don't believe they manufacture them this way with a time-to-live, but electronics, as with a lot of things, have a certain life expectancy and perhaps mine reached its limit. Now I have to research a new sound bar solution and I'm low on money right now with the holidays. Good news is that perhaps I can find a good deal somewhere, hopefully. I really liked the Vizio, but I am wondering if it's a good idea to buy another sound bar from them?
