@mayur unlikely that this would be caused by a bad LCD or a bad driver logic. I would suggest that you start with your settings first. Make sure that you have things like "mirrored" etc. not accidentally turned on. If your menu has a factory reset, try that.
If you are 100% sure that your settings are right and that a reset did not resolve this, you'll have to open up your TV and take a look at the boards. Check for obvious damage and post images of those boards with your question.
