Consumer Redressal

I had purchased Sony Bravio LED TV 32 Inch around 2.5 yrs back in RS 28000. Now I am facing blur images on TV. I raised request 25945671 on 13th June 2015. Sony person after inspection is saying that display is gone and it will take 12,000 for the display(half of the amount orginally paid for TV) and it had only 1 yr warranty. I had asked for discount so they just created another request 25976675 and no response from them till now. Whenever I call them it's just said you will get a call in 2 hrs ,managemnet is deciding on your case and then no response. I purchased Sony TV ignoring all other brands and this behaviour from them is not at all expected. I am ready to pay 5,000 but it doesnot make a point in paying 12000 for TV which was purchsed just 2 yrs back.Kindly help me in this case.
