It´s possible that the problem may be due to a damage in the t-con board, it
acts as a bridge between the LCD panel itself and the main board.
If there's anything wrong with the t-con board, it could produce a faulty display and colored lines in the screen.
The board itself is most often found in the top center of the back of the TV, often covered with an aluminum panel. Replacing this part can be a challenge, so if you don't feel comfortable working on your TV, consult your TV's manufacturer for support and possible repairs.
