Re: Samsung UE55KS8090 - Mainboard replacement failed

Hello Hauke,

In search of documentation for the repair of a KS8090 55inch that only showed colored Lines in The Middle Third with changing colors and Wirkung background-light and Wirkung Sound. I came across your thread. Unfortunately, there is no information if you have come further.

In my case i think it destroyed the mainboard. However, a used mainboard of identical construction and name only shows vertical lines on the entire surface of the TV, which change color as the content of the picture changes....
