The Vizio SV421XVT, is a very nice 42 inch lcd TV. With 120hz refresh rate, and 240hz scenes per second, this television offers depth perception found only in high end LED TVs.

The picture quality and black levels are very nice. The smooth motion is very visible and beautiful. Although we had to return 2 televsions to Vizio because they came with Stuck Bright Pixels, we are still very pleased with the TV over all.

I would not recommend buying a Vizio from Vizio directly. The swap out of the units we had with Stuck Pixels with Vizio was a long painful process, but that does not take away from the picture quality of this unit. I would suggest going the route of Amazon or Wally World when purchasing, no questions asked returns.

I updated this review and have shortened it greatly to focus back on the quality and performance of this unit.

Amazons customer service is great, but PILOT delivery is bogus, it is not white glove and they are liars.

That being said, I would recommend the SV421XVT to anyone wanting a good quality LCD at a reasonable price.

It does not come with the bluetooth remote, no apps, no wifi, no 3d, and it does not hold a mega contrast ratio in the millions, this is a late 2009 model LCD, but at the current Amazon asking price, it would be perfect for the standard families everyday use.

Deep blacks, little to no judder, bright whites, and crisp accurate color. 4 stars.

I purchased the Vizio SV421VXT from Amazon on February 6th, got it on February 12th. That's six days, and it didn't move for one of them due to bad weather. You'll see some complaints around about the shipping company for large items (CEVA) but I had no issues at all with them. Delivery company called, I told them I was at work, but could be home at any time for them to deliver, they just brought it to my work instead (at my request). This may not be an option for some, but it worked out great for me since I didn't have to take any time off from work to have it delivered. However, this review is for the TV, not the delivery company.

The set works great. I upgraded from a 27" CRT television to this 42" LCD, and obviously, the difference is stunning. We don't have HDTV yet, but even my standard definition Dish Network looks pretty good, as does my regular DVD player over S-Video. Blu-Ray and games on my PS3 look simply amazing. I find the sound quality to be very good without external speakers, but my living room is on the small side (the seating is about 8' from the TV)

Probably the only complaint I could say about this TV yet is that the cable they provide to hook to the wall so it won't fall over (if you aren't wall mounting) is kind of unsightly. However, most people probably won't use it, and this is a very minor detail. I just used it because, for one, this is a big purchase for me and I don't want to take any chances, and we have two cats that like to climb on top of the TV where it's warm...I don't think they could even lay on top of this TV, but I'm sure they will try.

I did months of research on HDTVs before settling on this model from Vizio. Overall, I found that no matter which TV you look at, there are negative reviews.

I upgraded my 120hz Vizio to this model for my family room and can't believe the clearity! The colors are crisp, the picture is 2nd to none. You can actually see the laces on a football while in the air on a spiral. For the difference in price from the 120 to the 240hz spend it! I did and have 0 regrets. The best TV I've ever watched mutchless in my own home!

If you want to purchase another big-screen LCD in less than two years, buy this!

If you think a product that costs this much money should last longer than two years, I'd keep looking...

I purchased this model 19 months ago, and about two weeks ago it started giving me green discoloration in any place on the screen where there is dark shadowing. So basically, LOTS of green! I've done a lot of troubleshooting, some at the instruction of Vizio technical support. The discoloration is present via the HDMI cable for my HD DVR cable box and via RCA cables for my DVD player and Wii...so therefore not a problem from the inputs--it's the Vizio. Since the tv is no longer under warranty, Vizio kindly recommended third party tv repair companies...sorry, but I do not intend to pay $350 (their quote) to fix a tv that was brand new and perfect less than two years ago.

A pretty thorough Google search indicates that this is not an anomaly (try it: Google 'vizio green screen') and that lots of other people have had this problem with their Vizio tvs. Apparently there is a way for me to fix it which requires taking the tv apart and replacing a $20 cable (another reason I will not be paying anyone $350!), but I have yet to try it. We'll see how that goes!

Bottom line, if you think such a big purchase should last longer than 2 years, keep looking for other brands. Or if you must buy it (I'll admit, the Gold Box deal price is pretty good...), do yourself a favor and buy the extended warranty!
