LG smart TV display damage

@akshaybedre you may need to rephrase your question since you are not telling us the model for your TV and how the display is damaged.

If it is a mechanical damage (dropped, hit on the display etc.), then you have to try and find a replacement panel. There is no other repair for it. Remove the back cover from your TV and you will find a label on the metal backing of the LCD panel. Use that number to do an inline search. You may need to check online auction sites like ebay.com or try to purchase the same model TV as yours that is broken other than the LCD. then harvest the display from that.
