I just purchased this TV from samsclub. WOW!. It has mindblowing 240hz processing. Picture quality is excellent.
I have never purchased a better product. It blows my father – in- laws Toshiba away, for HALF the price! I wish I had purchased it sooner!
Don’t buy a Vizio. I had mine for 15 months. 3 months past the warrents when the panel went out. Vizio would not help. The repair shop said Vizio would not help them either. Vizio claimed the don’t make the part to fix my TV. Now I have a $1,000 42″ paper weight called Vizio.
Tony you’re a moron for not buying an extended warrantee…. did you save money in the long run?
Did you purchase an extended warranty? Many people tend to spend about 1000 dollars on a tv, but don’t bother to dish out a couple of hundred more to insure their TVs. I have had an older 42″ Vizio plasma, and as an electrical engineer I know that electronics are not 100% efficient, so when it had a sound issue after the manufacture’s warranty I was covered with no problem. The repairman came and fixed it in less than a week. I had to deal with Sony for about one month and a half before I got any service!!! And this is a “known” name brand!!!
Clearly the unknowledgeble person here is Rick. Tim have you really thought this through? How do you think the warranty people can make 90% profit when they sell an extended warranty. If you want to buy it for peace of mind by all means buy it.. If your buying the extended warranty to save money 1 in 10 people come out a head. What percent of the 100,000+ units of this TV Vizio sold had defects in the first 3 years? After 2 years how expensive will a comparable TV like this really cost. Half as much? Maybe in 3 years it will even be obsolete?
I tried to post my review on VIZIO’s site but they refused to publish it – why??
The SV421XVT is an excellent TV with amazing picture. The remote is also very good with backlighted buttons and lots of functions.
However, so far I find several disappointing functions:
There is no TV Guide like other competitors, the Guide button only gives the same banner info like the Info button, and not a listing of all the local digital channels.
The PIP/POP function only works with different inputs and not the same input, for example, you cannot watch two local channels at the same time.
Also there is no clock, but the time zone is an item in the menu.
Hopefully, this TV will be reliable and last as others have reported problems.
How many people spend $1000 every 3 years on a new tv? Even if the technology is obsolete, the company replaces it with a newer model if they cannot repair the old one. In either event, a tv will surely cost more than the $129 for a 3 year extended warranty . In the end, most people will not end up using the warranty because the tv manufacturer would go out of business from the repair costs and bad reviews of thier products, butI’d hardly categorize that as “wasted money”. Do you have health insurance?

There is no clock to show the time on program info but the time zone is an item in the menu which is ridiculous.
The available screen formats – Panoramic, Zoom, Full and Stretch are not as good as Sony as they stretch too much horizontally making everyone too short and fat.
Hopefully, this TV will be reliable and last as others have reported problems.
I just purchased this TV the other day. I have to say I’m very happy with it! The picture is really good! The price…unbeatable! Got it for around 1100$ with the 2 year extended warranty, so I’m not worried about it at all! I’ll just enjoy it because it is a really nice TV. The 240hz is amazing when watching full 1080p bluray movies! The difference is so remarkable! PS3 looks 100x better than it did on my 37′ phillips! Which crapped out in under 2 yrs! Didn’t have the warranty though! Overall, Vizio is a good name that is gaining a lot of ground on the competition. While Sony and Samsung make excellent products, Vizio is right on their tale producing excellent products that cater to the more budget minded people! I recommend this TV, it really is a great buy!!
Costco adds a year onto the warranty for a total of 2 years. Tony and A. Chong’s post about disappointing functions appear all over the internet reviews under different names. What’s up with that?
I’m thinking about buying this brand (the new LED/LCD 55″) and a warranty may not be a bad idea if I do. It seems on every site I find Vizio has as many bad reviews as good. An extended warranty may be a good idea if your going with this brand. The bad reviews are not like the ones above… The ones I see are about the TV working for a year or so then breaking. It seems even though the tech for a great picture has improved the durability has taken a sharp drop( telling you all something you don’t know lol). I still have 20-30ish inch color tube TV in the garage that works as good as the day I got it 20 years ago.
Sams Club – $848
3 year extended warranty – $79.03, Goes into effect after the 1 year manufacturers warranty expires. In house service. If they can’t fix it, they’ll replace it or cut you a check for the purchase price.
