e701i-a3 lcd panel factory

If you are experiencing any of these symptoms you most likely have a bad panel, NOT a bad Tcon board-One side of the screen is darker than the other-Horizontal line or lines appear on the screen-A "dark" spot spreads across the screen

Bit depth is the number of bits used to indicate the color of a single pixel. The more bits, the more color range a panel displays. An 8-bit panel uses 256 levels per channel and displays 16.7 million colors, while a 10-bit one reaches 1024 and displays 1.07 billion colors.

This T-Con board failure is happening at 500 hours of usage and according to VIZIO affects those E701i-A3 TVs with serial numbers from LFTRNXAN4500001 to LFTRNXAN4702936.

If your VIZIO E701i-A3 is older than a year, your warranty will not cover the replacement costs for a new T-Con board. Fortunately the replacement RUNTK5261TPZH T-Con board is available for sale online for under $150.

The RUNTK5261TPZH T-Con board is located in the middle top of the back panel, usually under an aluminum cover held in place by four corner screws. It may also be held in place with foil tape at the top. It’s connected to the Main board through a black LVDS cable and flat ribbon cables.

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.

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.

The E601i-A3 is remarkably thin for the price, though a bulge in the back panel makes it closer to 2 inches overall rather than the specified 1 inch. The provided stand does not rotate, and the screen is reflective—though less so than some of its pricey competitors. All of its back-panel connections face either down or to the side where they won’t interfere significantly with a wall-mount installation.

The Vizio’s off-axis performance could be an issue with some viewers, but no more so than with most LCD sets. The color saturation starts to lighten a bit as you move about 20 degrees off center, and while it remains viewable well beyond that, it deteriorates progressively at wider angles. In screen uniformity, there was a slight unevenness in the set’s reproduction of a full black screen image, but it was barely visible. With a full white field, I sensed a trace of magenta discoloration here and there, but it was almost subliminal and never an issue in real-world viewing.

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.
