LED TV Samsung screen vertical shadow stripe or dark band

Anduser — Sun, 28 Jun 2020 18:00:39 GMT

I got a trouble with my Samsung UE55KU6450 Smart TV (4 years old):

When I turn on TV, screen works fine in the begining, but vertical shadow stripe appears a few later.

I note the same area at the rear of the TV is a little hot, as the bottom front.

I've tried auto image testing and trouble remains in all tests.

You will find the same issue been frequently reported in Google for different series of Samsung TVs, but not given a technical reason explaining what's up, nor a solution. Is it a LED stripe problem? A electrical issue? Could it be due to heat dissipation or panel pressure adjustment issues?

Here it can be appreciated the vertical shadow band

There may be a controller or motherboard just at the same area than vertical shadow because around there at the rear cover input AC is located.

So, is it possible that overheat at the electrical board is producing malfunction on the LEDS around this area?

LED stripes are not vertical so that overheat at the board area could explain the vertical shadow

Similar here. On the bottom of the TV some shadows appear.
What could be the reason?

Model: UE49MU6402UXXH

Did you ever get an answer to this? I’ve had my TV for about 25 months and have started to see the same issue (exactly the same position too)

I have the exact same problem. my 55 inch has the dreaded black shadow. its 4 years old but I think that after seeing so much of the same problems online then samsung should acknowledge it and fix it for free. all im getting from them at the moment is its out of warranty so will have to pay god knows how much to fix. they refuse to admit there is even an issue with their tvs. is there any advice for how to fight them? kind regards

Smoke came out because something burned inside when I turned on the TV a few months ago. I opened the TV and found a led bar burned.

I couldn't believe it: all the components were perfect, except the led bar, the cheaper one. Poor product quality, that's all.

Hi Anduser,

On your photo I don't see what is burnt 😞 Is it the grey silver piece?

Is it easy to replace?

Thanks

Hi Superjack,

I'm also facing the same issue with the 3.8 years old Samsung 55-inch TV. Can you please let me know how did you resolve this issue?

I have the same issue on my 3.7 year old Samsung 65 inch QLED tv. Will Samsung do anything even though the TV is out of original warranty?

I just started having exactly the same problem on my 50" TV. It look exactly like the image you posted.

Does anybody know what is causing this problem, what do we have to replace to fix this?

Re: LED TV Samsung screen vertical shadow stripe or dark band

This is caused by failed LEDs on the edge backlight strips. It's fixable on smaller TV sets, but the bigger the TV the worse chance you have to do it without cracking the screen.

It's not worth the effort and the money you'll spent IMHO.

LED strips inside are failing. $20 fix if you do it yourself

$20 and fixed it myself. Not that difficult to be honest

1. How large is your television?

2. How many strips did you have to replace?

3. Where do you get them? Part #?

Thanks.

It was the 55inch and replaced both strips as they came in a pair and figured if one was going then I may as well replace both. The tv model was un55nu7100. Ordered from AliExpress.

I have a vertical band about 2 feet wide in the middle of the screen, will the same two strips fix this? I have the 65 inch screen.

If it looks like the picture is fine underneath and just dim then yes …if it’s a discoloured stripe I don’t think so

Picture is just dimmer underneath, still viewable.
