I have the un55ks8000f, and midway through a video, the screen faded to verticle lines. The audio still played and the lines move, but nothing can be made from them. I looked through forums of other people with similar issues and tried cleaning all the cables and ports. The problem is that these lines show without any source plugged in. No menu or anything can be seen on the tv.

I get these as well in certain scenes on my Q80T. I figured it's one of the downsides of FALD.

Seems to be the case. A technician came in and replaced the panel, and the shadows are still there. Now I just need to decide whether I can live with this or not.

its possible what youre seeing is the backlight and so i was wondering if you are able to adjust the brightness to a slightly lower one and then adjust the brightness separately. ive seen lcd tvs where the backlight was set to max for a long period of time which resulted in burnin from behind.
as you mentioned, its easier to point out when the tv is displaying a solid color, especially a light grey one. does your tv have an eco sensor that auto adjusts brightness?

Unfortunately, I don't think this tv will let me adjust the backlight brightness. I couldn't find it in settings. I did see that it is does have the eco sensor, and that it is currently off. Do you think that I should turn it on or leave it off?

I would say leave it off. I was curious if maybe you didnt notice this earlier perhaps due to the brightness auto changing but i guess not :\

It's okay. Thank you for the advice! I really appreciate it.

Okay, have you contacted Samsung support directly? This may (mayyy) be a defect. It appears similar to "backlight bleed" but the vertical lines are from the backlight leds as theyre laid out vertically

I will try contacting them later today. I would definitely like to see if they can confirm whether this is a problem or not.
