vizio m502i-b1 lcd panel failure manufacturer

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.

Vizio is a Southern California-based consumer electronics company founded in 2002 by William Wang. The company makes flat-screen televisions, wide-screen televisions, ultra-large televisions, and smart TVs as well as all-in-one desktop computers, notebooks, and tablets. The company stopped making plasma televisions in 2009 and continues to make LCD televisions, which have power supply boards that may be replaced.Can a flat-screen TV power board be replaced?

Flat-screen TV power units can be replaced to repair a faulty TV. If a flat-screen TV will not turn on and has no picture, the power supply may need to be replaced. The component required for TV repair supplies power to turn on and power the LCD flat-screen television. Different power supplies may have different numbers and types of connectors to the internal chassis. Not all Vizio power supply boards will fit every flat-screen television.How do you choose the correct Vizio power supply board?

Much of the information required for selecting the appropriate Vizio power supply unit for repairs will be located on the back of the television housing. Find the Vizio model and serial number identification panel.Locate and write down the Vizio TV model number.

You may access the power board for Vizio televisions inside the television attached to the chassis. Power boards connect to AC power cords and then distribute the power throughout the rest of the television. Follow these steps to access the component:Unplug your television.

Locate the flat power unit, which will have capacitors and connectors. The majority of Vizio power boards are located on the left side of the television chassis.

Vizio makes several versions and sizes of flat-screen televisions. Some flat-screen TVs may have similar-appearing power supply components. Check all power board specifications. A power board that fits one of the brand"s TVs may not fit or operate properly in another model, even if it is the same size of screen and chassis. Ensure all power board specifications and parts numbers match for correct installation and operation.

The Vizio M502i is reasonably priced at $729.99. There is less than a $200 difference between the 50 and 55 inch sizes. If you have the room for the 5 extra inches of screen space, it may be worth the extra cash. Otherwise, it"s an excellent value for the amount of screen space and features included. The 2014 rendition of the M series has focused on upgrading picture quality and smart TV features. It is important to note that Vizio has ditched 3D playback in all M series models this year. It keeps the price down, but may not be good for those who have been building a 3D content library. Full-array backlighting is the star addition that has a direct effect on the overall picture quality. This bumps the contrast to levels that compete with some of the big name TV manufacturers. Vizio"s internet apps plus provides access to all the streaming services you"ll need as well as second screen abilities for smartphone and tablet integration.

The overall 2D picture quality of this TV will depend a lot on the picture mode you select. Active LED Local Dimming with 32 zones to enhance contrast control is one of the standout picture quality features of the M502i. Black levels are more saturated than we saw last year, and the TV certainly has plenty of brightness in whites. Active Pixel Tuning helps even further by addressing contrast issues at the pixel level for stronger brights and darks. In terms of sharpness, we"ve seen better from the big names like Sony and Samsung. This is a result of the picture processing engines and Vizio is certainly not among the worst. To further the screen refresh rate, Vizio includes a 720 Clear Action Rate feature. This backlight scanning feature will help with sports programming and fast action, but is better off left disabled most of the time.

Vizio has added a Plus to the name of their smart TV features this year. 802.11n wifi is built into the TV for speedy connection capable of problem free HD streaming. Some of the highlighted content streaming apps include Netflix, Hulu Plus, Amazon, Vudu, Pandora, and all the social media you"ll need. The new backlit remote even has dedicated buttons for Netflix, Amazon, and M Go. The whole platform has recieved a redesign with HTML 5 in order to achieve an inuitive user interface. We think it is an improvement upon previous iterations. Second Screen interactivity is also a feature for iOS and Android devices. Compatible apps will be able to broadcast their content to the M502i"s display without any wires.

My vizio tv worked fine last night and try turning it on this morning and can’t get it to power up? I tried disconnecting all wires and still nothing? TV is a little over a year old.

Ok, had a power outage. TV had no juice for hours after power came back. Left it unplugged, tried it tonight after 24 hours and the Vizio logo lights up showing it has power but doesn’t turn on. I cycled the power but nothing. What could this be? Power received but not turning on?

My Vizio tv stopped turning on unless it was off for at least one hour. It would just try for a second and cut off, sometimes not even showing the Vizio sign. That was a two day window. Now, it just flat out doesn’t work. Of course, I purchased it at the end of 2014, which puts it barely outside of the one year warranty range. Unless they fix it free of charge, I’m starting/joining a social media campaign to make people aware they should boycott Vizio. I’m furious.

I’m also having this problem now. Vizio ESeries 5034, 13 months old. Noticed a few weeks ago where it would take 2 or 3 tries to turn TV on. It has slowly gotten worse, now it’s really hard to turn it on. I read somewhere that this might be caused by defective capacitors on main board. I have 0 experience with this kind of stuff, but since a repair costs $300 in my area I might try to change the capacitors myself, repair is pretty much the price of a new TV

I purchased this tv because it and Vizio had a good review and the picture was great and it had a lot of desirable features. Less than two years later, and thankfully was still under warranty, the tv died. They said it was the power supply and apparently this is a know issue. Vizio customer support was great and since it was still under warranty, they sent us a refurbished model of the same tv. I wouyld have preferred a new set since that is what I paid for but, I felt it was still better than no tv. Less than six months later guess what? Yes, that tv died. Now they are sending a lesser refurbished model. Again, better than nothing, but I will never buy another Vizio based on being so unreliable. Two years, two tvs fried. I expect this replacement will only last a matter of months

My Vizio does the same thing.. Complete piece of crap. If the tv is left plugged in after watching it that night before, it often won’t turn back on the next day.. The power light lights up, but no picture is illuminated.

If we unplug the tv the night after we watch it and then plug it in right before we watch it the next day, then there are no issues and it works fine. Of course, this happens about 15mths outside of the warranty. Luckily, I purchased the tv with my Amex, so they refunded me for the $330 estimated repair, but I now don’t have any faith in Vizio’s products. Terrible company with a sh*t product.

I have a Vizio 42″ E422VA over a yr old so out of warranty. 3 mo ago the HDMI ports started Not working, now the TV does Not turn on. I opened the TV short circuited the fuse and still not working. PLEASE BOICOT VIZIO THEY SELL TRASH TV’s!!

Yep, we had various minor problems with tv from day 1 but would call Vizio and get some minor help for a while. We bought our tv from Costco so 2 yr. manufacturing Warranty but never thought to call Costco Conciege always went through Vizio they don’t know 1/2 of what they should for their tech. support. When we just passed the 2 yr. mark the problems magnified by quadruple and we kept thinking “oh, the next firmware update will resolve all isues”, and sometimes it helped a little sometimes not. Luckily we paid for extended Squaretrade Warranty and now working on getting a repair but have so many issues don’t think 1 repair item will resolve all so hoping that they will have to replace it…
