VIZIO TVs are not worth the money at all, at least not the model listed above.
Our first VT420M unit (bought in Sep 2009) lost volume 105 days after we bought it. Fortunately, WalMart pushed the 90 day return policy a bit, and exchanged the unit for a new one. That occurred in January, 2010.
Here it is, June 2010, and the second VT420M is no longer functioning, just 5 months past 2 years!! (All warranties are expired; planned obsolescence?!) This unit turns on, shows the VIZIO logo on screen for 5-6 seconds, then goes blank and nothing can be done with it-----no response from the "input" buttons, no response from "menu" button. A turn off, then turn on repeats the same.
Before VIZIO, we had a SANYO that worked beautifully for 15 years---and was still going strong when we donated to a nursing home!
Forget about VIZIO; put your money elsewhere.
