Blinking black vertical line on screen


Novice Member

got my samsung ru65 uhd TV 14 months ago. But soon after, after few minutes of watching tv, a flashing or blinking black vertical line appeard. Once it starts, it flashes every second. I contacted samsung support they said I should update the software and turn off the TV an push 10 Seconds the power button. But it did not help.
has someone had the same problem and knows what the cause / solution for this is?


it is caused by a thin flex that connects control board of the panel to the crystal. It can be resoldered (is pretty hard and may end up in total failure)
If you are under warranty get panel replacement.

Thanks for your reply! Its strange . 2 weeks ago i changed the picture setting to „dynamic“ and since then the vertical lines did not appear anymore. Normally they start appearing after 20 minutes.
