How to fix black lines in screen

@mithleshmehta that is a tough one to fix. This looks like an error on your driver boards/connections to the LCD screen. You would have to remove the rear panel and then look at the top of your LCD screen between the screen and the top of the inside case. There should be a few long, skinny boards connecting via ribbon cables (those can't be removed). Gently push on the ribbon cable that comes from one of those boards and connects to the LCD exactly where your black line is. See if that changes anything. If it does then you know that the cable has lost its connection and is actually off the LCD. It can not be repaired by DIY means.

We can try an provide you with more guidance if we can see what you see. For that,you want to go ahead and take lots of pictures of your boards and the ribbon cables etc. We might find something that you are overlooking etc.
