e701i-a3 lcd panel made in china

Hey all. Brand new to the forum. I just acquired one of these TV it has been troubleshooting it no picture condition. I"m really surprised that I went to Target yesterday and found the same exact TV still on sale along with a 60 inch counterpart. I found sharp panels used in very very many large screen TVs. Anyway one of the three pin transistors most notably the one labeled COXA has apparently a short between the center pin to the top right. This transistor operates what appears to be is a 3.3 volt voltage is for the gamma IC processor. I have two of these boards both with the same problem the new one that I ordered I haven"t even connected to the panel yet and it was failed from the box. It appears that these boards for previous buyouts from previous failures it has a Chinese label on the back of the board but it came from ebay in the US. I myself am trying to still figure out what"s going on I contacted the vendor and they"re setting yet another board. I can"t seem to locate even in my parts stash thid 3 pin MOSFET with this label. Cox is the equation for the silicon inside the MOSFET it has something to do with the wavelength. This is a really odd transistor. I think its funny how shopJimmy sells this transistor and the EEPROM 8-pin IC. Has anyone successfully repaired this board yet are replacing the components?

, I originally tried just disconnecting the power to the side driver boards and what that did was presented a very dark image on that side which was very slow motion and blurry 2. The only reason I figured that the side tab drivers on that side were having problems is because when I first connected the t-con board one side at a time one side I had a good picture the other side started flickering and then it cut out so I knew there was a problem on that side first. After that with the one good side connected on the tcon to the panel I realize that there is a white strip that did not seem to be affected on the screen even though the other side was not connected off the tcon. I realized that there was a problem with the tab driver in that section and on this particular panel if one of the tab drivers are not making a good connection you"ll have a strip on the screen that looks perfect but the rest of the panel will be dark and blurry on that same side where it is disconnected from the t-con board. That"s how I knew that when I started pressing on the tab the good strip section would start to get dark and blurry like the rest of that side of the panel essentially there was a short in that section then when I pull that off the panel I had a perfect area working so that"s why I removed all the drivers off the right side.

Now the left side is doing all the load that the left and right were doing at the same time so the score I don"t know if the panels going to last too long but it"s still working perfect. But hey if you got no other alternative and you know that it"s going to meet the junkyard give it a shot its worth it

To my finding the reason that it keeps blowing this one transistor which is usually the only problem on the tcon board is because of a failed horizontal driver tab on the right side of the LCD panel. It appears that usually only one of these tab drivers fail. With this particular set up the main board does not have the ability to shut down the TV in protection mode like some other manufacturers do. The tcon board and the panel are both made by sharp. The problem lies within the driver IC built into the tab on the panel.

If you have this problem and you order a new t-con board, do not and I repeat do not power up the TV with the new board before you try this first. On the right side of the screen, if you"re looking at the back side of the TV then look at the bottom left, you will find a small white ribbon cable that connects the side boards of the panel to the bottom boards of the panel. You want to disconnect the white ribbon cable connecting to the right side board you should see the ribbon cable connector on the bottom of the screen on the side. Just disconnect that small white cable. Now you should be safe to power on the TV with the new board. If what has happened to your TV is correct, you will see the screen presented itself with a nice solid bright picture on the left hand side on the right hand side it will be dark, and possibly a little blurry. However you will see as small section spanning horizontally that looks completely normal. And what I mean by normal is that it"s just as bright on the right hand side in this small section as it is on the left. Wherever this lies on the screen is in the same area where you have the failed driver.

Now then I don"t endorse this as a permanent fix but if you have given up all odds and you"re about to throw this TV out in the trash because you cannot make it work anymore many have tried everything, what I did to Repair mine was carefully peel on the right hand side driver tabs directly clean off the panel. Remember this is only done on the side that is causing the failure. A few have had success with this and some have not. I however had excellent success with it so far.

Our research indicates the Vizios with the bad chip assembly were made and offered for sale in the 4th quarter of 2012. We checked our local Costco and verified all the E601i-A3 and E701i-A3 now being sold are new production, past the serial numbers of the recalled models.

“A limited number of VIZIO’s E-Series 60” and 70” LED Smart TVs (model numbers E601i-A3 and E701i-A3) may experience a loss of video due to premature failure of a chip assembly sourced from a supplier.  VIZIO is working with its suppliers, retailers and consumers to resolve the issue as quickly as possible for affected users.  As part of its continued dedication to customer satisfaction, VIZIO is proactively communicating with its customers through direct contact with registered owners, through VIZIO’s retailers and through online and social media about the potential issue, what to look for, and how to reach VIZIO’s dedicated support team to receive help.

In a small percentage of units with serial numbers in the ranges of LFTRNWAN3800001 to LFTRNWAN4805300for Model E601i-A3 and LFTRNXAN4500001 – LFTRNXAN4702936 for Model E701i-A3, users may experience a loss of video on the display although audio can still be heard.  This issue is attributed to a limited batch of chip assemblies from a supplier, in which there is a small percentage chance that the chip assembly prematurely fails; this causes the timing control board to be disabled, which disrupts the video signal to the display.  This potential issue appears to occur typically around the first 500 hours of usage or first few months of normal usage and does not present a safety concern.

VIZIO has promptly notified its customers of the possible issue so that affected users can have their units repaired or replaced free of charge.  In addition, VIZIO is also extending its standard one-year limited warranty to two years from the date of purchase for this specific issue to ensure that customers who purchased the E601i-A3 or E701i-A3 can continue to enjoy their TV with full peace of mind.

If you have a VIZIO E-Series 60” or 70” TV with a serial number that falls within the ranges of LFTRNWAN3800001 to LFTRNWAN4805300 for Model E601i-A3 andLFTRNXAN4500001 – LFTRNXAN4702936 for Model E701i-A3 and experience a loss of video, please call VIZIO’s Customer Care team toll free at [email protected] to directly reach our dedicated service team who will assist in resolving your issue as quickly as possible.

When they first arrived a few years back, LED-driven LCD TVs with a full array backlight made a big splash. Why? Because the backlight, a grid of LED lamp modules spanning the rear of the display panel, can be modulated via local dimming — a process that enables the set to track specific areas in the image, turning select modules on, off, or somewhere in between.

When I tested Sony’s flagship XBR-55HX929 TV for our November 2011 issue, I called it out as having “the best-looking picture I’ve seen from an LCD TV in a long time.” Jump forward a few months, and I’m attending a demonstration at Sony’s HQ. During the demo, Sony put its flagship XBR, a model with a full-array LED backlight, up against a group of other TVs, including the company’s new edge-lit HX85 Series set. If you follow our reviews, you’ll know that LCDs with edge-lit LED backlights typically don’t fare well, mostly due to screen uniformity issues. However, the HX85 set in Sony’s shootout not only smoked the competition but was about on par with the company’s XBR model. Naturally, I was eager to get my hands on one.

Black Friday — the day after Thanksgiving, and the biggest shopping day of the year. It’s a day when hordes of Americans head out to the local mall or Walmart, ready to fill their carts and, if necessary, take you out should you stand in the way between them and a good deal. TV maker Vizio has traditionally released a new model or two just in time for Black Friday — often at prices well below the norm for sets in their category/screen size. The E601i-A3, a 60-inch edge-lit LED LCD, was one such special, having reportedly sold for $699 on that day — a price that is, well, insane. But now that the E601i has bobbed back to a more real-world, though still very affordable, $999, it’s time to check out how it stacks up against the competition.

The last three flat-panel HDTVs reviewed in these pages averaged over $4,000 each—a figure inflated, to be sure, by one of them costing $6,000. Statement products tell us what’s possible and where the technology is going. Most Home Theater readers want to know these things.

LEDs and 3D. Add in Internet connectivity, Wi-Fi, and an ultra-thin panel, and you have the mix that matters in today’s HDTV market. That also describes Toshiba’s new 55-inch 55WX800U. Together with its smaller sibling, the 46-inch 46WX800U, it makes up Toshiba’s current 3D lineup.

With plasma TV tech seemingly on a path to early, unwarranted extinction, prospective TV buyers unwilling to spring for OLED soon won’t have much choice other than to purchase an LED-backlit LCD TV (aka “LED TV”). And while the performance of such sets has improved quite a bit over the years, the better ones are still expensive for what you get—particularly in comparison with same-sized plasmas. So, what’s a quality-conscious consumer to do? Roll over and get eat the high prices? Not necessarily.

It’s long been true that if you wait long enough, the price of technology will drop down to meet your budget. Flat-screen HDTVs are prime examples. We’ve recently seen manufacturers respond to the current global financial malaise by squeezing their beans hard enough to produce decent sets for around $1,000. While it’s difficult to say if this trend is due to economic conditions or pressure from price-aggressive new manufacturers, Vizio has been in the vanguard of the young guns making life difficult for traditional HDTV companies. And the company’s not standing still. Exhibit A: Vizio’s new $1,000 E601i-A3. Like its big brother, the 70-inch, $2000 E701i-A3, it’s a true budget buster, but for a change, the budget they’re busting isn’t yours.

When Tom Norton reviewed the 65-inch Vizio XVT3D650SV 3D LED-edgelit LCD TV last year (see review here), he found it to be an excellent performer in most respects. However, its list price of $3,700 kept many potential buyers away—and, along with the few problems he did find, kept him from bestowing HT"s Top Picks designation.

Vizio opted to take some bold steps for their 2014 lineup of LCD TVs. The first was to get rid of 3D—no huge loss there, since most folks don’t watch 3D outside of movie theaters anyway. The second was to add a full-array local-dimming backlight—and not just to some of the new models, but to all of them. The entry-level 55-inch E series set that we reviewed in the July/August issue featured 12 dimmable zones. For the 60-inch M602i-B3 under scrutiny here, that number gets bumped up to 36. Do all those extra zones make the M602i-B3’s black-level performance three times as good? Read on to find out.

Ultra HDTVs that support the display of programs with high dynamic range, also known as HDR, have quickly become the norm. If you’re out and about shopping for a new set, there’s a good chance that you’ll be taking home one of these TVs. Of course, the benefit to a state-of-the-art feature like HDR becoming standard is that prices for sets that include it will drop. How low? How about $1,100? That’s what Vizio charges for their 65-inch M65-E0 LCD Ultra HDTV.
