No video but audio is clear.
Audio is clear but no video. How much it will cost to repair.
ANSWERS:
@aujalya help us to help you. We need to at least know the make and exact model of the TV. You need to let us know what you have checked. I would at least start by turning the TV on and setting it to a station where you have audio. Then, in a darkened room, shine a flashlight at an angle against the screen. If you see outlines of the station on your screen you know that this is a backlight issue. Most likely culprit could be a bad power board or a bad t-con board. All of this will depend on the make and model as well as your troubleshooting skills. You can always remove the back of your TV set and take some good pictures of the boards. Post those with your question so we can see what you see. Use this guide Adding images to an existing question for that
