The picture you have uploaded shows a Samsung TV with colored lines, not an LG TV. Check what you have and report back your findings.

ratheeshan_9  double check the way you added the image. It does not enlarge for me. It appears as if your menu etc. is working and showing as it should. Try all the different video inputs and see if that makes a difference. This could be an issue with the main board (LVDS connections or components) Eventually you will have to remove the back of your TV to look at the cables and the boards. Post some good images of those with your question so that we can see what you see and possibly identify the parts you could measure the voltages on. This may narrow it down.
