TV has sound but no picture. Backlight works. Vertical banding.
Samsung UN55KS8000FXZA TV was working fine while playing videogames. Screen instantly went to vertical lines. No discernable picture. Sound works. Backlight works. Took apart TV and checked ribbon cables. Cleaned and tried wiggling and tapping all connections and cables.
While the TV was powered, these measures made no difference. Even with all inputs disconnected, the picture is just vertical lines. They shift and move while pushing buttons to navigate menus. I suspect the main board is the problem. Model BN94-10961N main board. Inspected power board for faults. All capacitors look good. Power is getting to main board. TV is only a year old, but just out of warranty. Way to go Samsung!
Is dit een goede vraag?

Did you figure it out because that is exactly dead on what mine looks like and would love to have a possible fix

It was determined to be a bad pcb on the screen. It isn't replaceable without replacing the whole panel. I bought an LG TV to replace it. It was my 2nd Samsung failure in 4 years. They're losing my confidence in the brand with the sub par electronics. The hardware seems great. But I've been plagued with premature failures with their products. Phones and tvs.

Hi,
My tv (UN55KS8000FXZC) has the same exact problem. Like you, my screen suddenly turned black with colored vertical lines in the middle. I’m now stuck with that! Can’t do anything about it! Very disappointed by Samsung quality department (do they have one?) anyway, did you manage to resolve your problem? If yes, can you tell what was the problem and how you proceeded to resolve it. I’m very interested!
Thank you very much!
