vizio m502i-b1 lcd panel failure free sample

postal1in, it is pretty impossible to find replacement displays. If you do find them then the part and shipping are most often more than a replacement TV would be. You can try an look it up by the number on the LCD itself and see if there is anyone selling those. I would suggest that you try and find the same model TV that has other issues and switch the display.

Nope, it"s not 4K, and no, it"s not quite as good a value as the E-Series, but it"s still pretty friggin" sweet. Vizio touts the additional local dimming zones of the M-Series as its main picture quality advantage, but in my testing the real differences between the two were slight. Both create an excellent picture, and since the E is cheaper, it"s a better value overall.

But unlike some TV makers, Vizio offers step-up extras that might be worthwhile to a lot of buyers. Foremost is better styling than the E, as long as you like silver. Then there"s the better remote, including a full QWERTY keyboard on the back that (gasp!) actually works with the Netflix app. And better motion performance, as long as you engage the Soap Opera Effect.

So while I don"t recommend the M as highly as the E overall, both represent tremendous values, and will likely set the pace at or near the top ofCNET"s Best TVs list for a good chunk of 2014. They also heighten my expectations for the P series and R series of 4K TVs, both due sometime later this year--Vizio still hasn"t said exactly when.

Vizio"s remote is the same on the topside as last year"s M-Series, and while it"s better than the one from the E models, it"s still pretty mediocre. There"s no backlighting, little key differentiation, and the arrangement of keys around the cursor always tripped me up.

In describing the local dimming on all its lines, from the entry-level E-Series on up, Vizio is using the term "full-array" this year, instead of the term "direct" it behind the screen, as opposed to along the edges, generally improves picture quality, particularly uniformity and dimming performance.

But not all full-array local dimming LED-based LCD TVs are created equal. Many of the extremely expensive full-array sets that have defined the breed in the last few years, like the

Another improvement over the E-Series is motion handling. Vizio is careful to say the M-Series has a "up to 240Hz effective refresh rate," but like many TV makers, clouds the issue further by using a higher, faker number, in this case "Clear Action 720." Check out Video Processing below for details on how it compared to the E-Series and other LED LCDs. Unlike the E, the M-Series gives you the option to engage the Soap Opera Effect if you like that kind of smoothing.

You may also notice the absence of 3D in the chart above. Many of Vizio"s previous TVs, including in 2013 the M series and a few "E" series models, offered passive 3D compatibility. This year Vizio has dropped the feature entirely, announcing no 3D-compatible televisions so far in its 2014 E, M, or P or even the high-end R series.

Vizio"s content selection is very good. HBO Go isn"t available (it"s still a Samsung exclusive among TVs) and there are no major sports apps like MLB TV, NHL GameCenter or NBA League Pass, but most of the other heavy-hitters for video are. The meta-app "Web video" itself contains numerous sub-apps of specialized videos.

As noted above, the other big difference on this year"s M and higher Vizios is the company"s QWERTY "flipper" remote. It works by infrared, so sometimes the signal doesn"t reach the TV, but with apps that support it the physical keyboard is a real boon, particularly for logins and searches. I was happy to see Netflix is among the supported apps, but for now Amazon is not.

Unlike most other major TV names Vizio still doesn"t offer a Web browser in its Smart TV system. In our experience that"s no major loss since it"s usually easier and better to use a laptop, tablet or phone anyway, but it"s worth noting that some TV browsers -- namely Samsung and LG -- have improved a lot recently. Vizio"s system also lacks the many extras found on some, including cable-box control, universal search, voice command, and more.

Picture settings: For 2014 Vizio has made a lot of changes in this department, but the M and E series share largely the same settings. Vizio offers a number of preset picture modes that don"t allow any adjustment; changing a parameter like Brightness on one of these modes immediately changes the picture mode to Custom.

Normally I don"t like that kind of arrangement since it"s a bit confusing and can lead to inadvertent changes of your custom settings, but Vizio has a cool solution. Not only can you lock the Custom modes, preventing any changes, but you can also create and even name entirely new modes.

Beyond modes Vizio has added some additional controls, namely a full color management system and a ten-point grayscale control. There"s a "Motion Blur Reduction" that engages backlight scanning to improve motion resolution, but only in conjunction with the "Smooth Motion Effect" setting, which turns on the Soap Opera Effect. (See Video processing below for details.)

During the darkest sequences of "The Hobbit: An Unexpected Journey," for example, the two 2014 Vizio"s looked very similar in terms of black level. As Bilbo and the dwarves nosh around the campfire in Chapter 12 (57:16) for example, the letterbox bars and the silhouettes of the trees were equally dark on both, roughly matching the Sony W900A and as well. Only the Samsung plasma maintained a consistently deeper black, while the Samsung F8000, Sony X850B, the Sharp and the 2013 Vizio M series were lighter, lagging behind to varying degrees.

Like its less-expensive 2014 brother the M correctly handled 1080p/24 film cadence, something older Vizios have not. On the other hand, it couldn"t do so and simultaneously preserve full motion resolution, something Samsung sets excel at. To get correct film cadence on the Vizio M you must turn the Smooth Motion Effect control to Off; any other setting introduces the smoothing Soap Opera Effect.
