Samsung UE50NU7400 with black lines

[Avinitlarge]

Hi
I’ve got a Samsung 50” with a flickering lines. I’ve done a reflow on the main processor but the issue was still there. I tested it the next day and the fault had gone and has not yet returned.
Are there any common issues? The motherboard is a BN41-02635B

Sorry for the bad picture, I had to screenshot the video I have of the fault.
Thanks

My Samsung has just developed this same fault but before I do anything, how did you get the back off? Can't see any screws [haven't removed the stand yet though]. Is it all clipped on? Don't want to break everything completely.

Thanks

It has clips all the way round

And if you don't use the right tool you will break the rear cover. Samsung at it's best.
