My new Samsung model 7050 Series 7 55" HDTV LED Smart TV has picture problems. When watching the TV the picture will have fragmented pixels that flash on and off the screen. The picture is fine at times, but the constant flash of the pixeling is frustrating. Thank you for any assistance.

Step by step online troubleshooting available.

The common cause of this issue is down to a board that connects the screen to the main circuit video board of the tv. It is usually located top middle of the tv and has 2 white ribbon type wires coming from the top and is normally covered in a metal shield.
There will be a part number on the circuit board, this will be the one to find online which matches your screen. If you got an identical tv with another fault, it may not have the same part as each combination is different depending on the manufacturing line or part revisions.

The part you are looking for is called the T-Con board . Hope this helps.

Hi William I have the same tv. It had the same problem. I had to have the main board replaced. It seemed to fix the problem of turning on and off randomly but now i have a problem with the screen.

Like its predecessors such as the J6200 and the J6300, this model offers the same LCD flat screen panel for a crystal-clear viewing experience. However, there are several variants in the features for the JU6400 that will make it a worthwhile upgrade from the traditional Full HDTV. 4K Ultra HD resolution is offered on every TV in this series which provides the best possible resolution available today. Other new additions include the Micro Dimming Pro feature which allows the TV to fine tune the image by adjusting the cells in the LCD display. This provides the viewer with perfect lightness and darkness levels on the screen for a true-to-life image.

The Smart TV platform for the JU6400 series is powered by the Tizen operating system. This new update for 2015 provides owners with a complete overhaul from the previous Samsung Smart TV interface. New features include the full Samsung App store that offers access to today's hottest applications such as Facebook, Amazon Prime and Netflix. The menu and browsing options are also much easier to access and use than those offered on previous Smart TV models.

While the Samsung JU6400 is an exceptional option for anyone who wants to purchase a model with better resolution and more futuristic features, it does not include some of the latest features offered by the brand. Innovative extras such as the Smart Control remote and the new Curved screen design are not offered in this particular series. 8.0Great

Fix your tv with black screen blinking light, popping sound noise. ... Watch QueueQueue ... TV Black Screen - Repair LCD LED PLASMA - Problems SONY LG .... I have a 60 inch samsung DPL tv how can I stop the humming or ... What do I do if my tvturns on but its just a black screen so sound no picture?.

Here is what to check when your TV is turned on, power light is ON, but no picture is seen or sound is heard:

1 - Be sure the component you are using (Xbox, Cable, SAT, ROKU) is turned ON.
2 - Check to be sure all cable and cords are securely connected to the TV inputs and component outputs.
3 - Make sure you are on the correct input as some TV's will show a black screen if there is nothing connected to that input.
4 - Unplug the input you are trying to use from the TV (such as an HDMI Cable) and plug it back in.
5 - Check for signs of damage on all cords and cables from the TV to all components.
6 - Make sure the TV is not in ENERGY SAVE MODE, press the button on the remote control to go back to normal mode.
7 - Unplug the TV for 10 minutes to see if there was a temporary one time issue with the TV.
8 - Disconnect the TV from power for 2 minutes, then when plugging it back in PRESS AND HOLD THE POWER BUTTON ON THE TV FOR 10 to 20 SECONDS to try and force the TV to reset.
9 - If after checking all these different issues, you may have a Faulty Power Supply Board, A Bad Capacitor on the Power Supply Board, Loose Wire Harness, or Loose Ribbon Connector in the TV itself.
10 - Most likely when a TV has the power light ON but NO PICTURE and NO SOUND, it is the Power Supply Board that has failed.
