Tv screen have black line

@prasadgane15387 first you need to verify that this TV is a LG 32CS560, then you need to tell us about the black line. A single pixel vertical line is commonly caused by a TAB error, A thick black line is caused by a faulty ribbon cable from the driver board to the LCD panel or a failure of the driver board. A horizontal black line is commonly caused by a failed GATE driver which is part of your driver boards. As you can see there is no easy way to answer this, unless we have more information. Take some good pictures to show us what your displays shows and what this line looks like.
