Samsung UE55JU6800K Bottom 4 LED Strips Not Working

[Harry_W]

Hoping for some help as the bottom four LED strips on my Samsung UE55JU6800K TV are not working. I've replaced all of the LED strips for brand new ones and also swapped out the power supply for one that has been tested and it's still not fixed the issue. What else could be causing the issue? Could it be a faulty LED backlight interface?

Anyone?

What LED strips? Are they built into the TV?

These are the ones I bought:

But they're not connected to the TV are they?

Yes they are the LED backlights connected to the TV...I've replaced them all but four strips are still not.lighting up..I've changed the power supply board also and still not working.

You may be better asking in a Samsung TV specific technical forum if one exists? Or ones dealing with AV products in particular?

You have, I presume, got the service manual downloaded and can read and understand it? and have the necessary test gear?

There are YouTube videos on that model, even - not that they seemed to show much?
