Summary: We bought this 47" TV in November 2010. We also have a 32" Vizio.Both have Great pictures. The main control board broke on our 47" 6 months after the warranty expired. Vizio said they can't fix it under warranty. I had to have a third party repair the TV. I thought that this TV was a great value but if Vizio won't stand behind the warranty for such a key operating component so soon after its expiration then I will purchase another brand going forward.
Summary: Initially I loved this purchase, except for some occasionally strange behavior that required my resetting the TV a few times. I was overall pleased with Vizio's support in this. However after a few months the remote control would occasionally not function, and resetting and/or changing batteries wouldn't solve it. It has now stopped working completely, which due to Vizio's design of the TV doesn't allow you to do much beyond the most basic TV functions.
Summary: I purchased this TV, but ended up returning it after 8 days and going with another brand. Why? The TV experienced problems after 5 days of operation. The set would freeze (remote wouldn't work, couldn't access any menu's or functions on the TV with either the remote or the knob on the side) and couldn't be turned off unless I unplugged it.
