I have been facing this problem since last 8 months. There is a black line covering half my screen and hence unable to watch the upper portion of my 40 inch LED TV. In May 2013, I had an engineer visit my place and he very bluntly concluded that we need to change the panel and the same would cost Rs. 24,000. This is not reasonable as in just 18 months of purchase, I need to spend Rs. 24,000 for repairs! This is definitely a case of selling a defective model. Last month the customer care official called and offered me a discount of Rs.4000. Still thats not asking to too much. Request you to please suggest a cost effective solution for the same. I have been using Samsung products and have due respect for the brand. Hope you care for your customers and believe in providing reliable products and services. Look forward to your response on the same.
