ok guys i called up customer care,they sent a service guy he told me that they will replace the panel with new one. he told me to bring the LCD to service center, but as of now i am busy so i told him i will bring it in next month. because warrant is still up to NOV-2011. he also told me about an yearly package of service for 4500rs. i didn't enquired about it very much. so waiting for panel change.
