Consumer Redressal

I had purchased a Sony LED TV (model : KDL40EX520) on 18/04/2011, from a multi brand showroom, which costed me 62000. On 5/11/2011 there was a issue with the display panel and had complaint to the company about this, and the company had sent there technical team and replaced the display panel free of cost as it was under warranty period. No exactly after 2 years of replacement I am facing the same problem of the display panel. Now as the warranty period is lapsed I need to pay for the display panel which is of cost 21600. I want to register a complaint against the company because it is happening for the second time and they are now telling us it may be because of power fluctuations. But we have installed a branded stabilizer. And they are telling the electronic goods are such that we can\'t give any kind of assurance of the life.
