"Vertical Lines on my Samsung LN46c630 LCD tv"에 답변This has vertical and horizontal lines as well as i can see from the pictures. Usually horizontal lines means the LCD is bad, i read on some forums. However, i have same like issue on a Samsung UN55D6400. Trying to replace the t con board, the TV has only vertical lines and picture is bright and crisp. So will try the new board in and see.
