I have 40" led sony bravia purchased @ 65000 inr which is now 5 years old. Suddenly display panel is showing black vertical lines on the screen, sony engineer told to fix this its require new panel costing 20, 000 inr. Now after reviewing lot of websites and customer forum i found this is manufacturing defect as almost all televisions are facing same problem. Need consumer forum team help to get my faulty models fixed from sony it is manufacturing defect.
