[Resolved]  Sansui Pj29multiplex — picture tube defect

We purchased sansui PJ29MULTIPLEX tv in the year[protected], from SNEHANJALI-J.P. road, ANDHERI-WEST. Unfortunately, during shifting of residence our bill and warranty card has been misplaced. During last week, at times we could hear only the sounds while the picture was not seen. And now, neither the sound is heard nor the picture is seen. On complaining, the serviceman visited and inspected the tv and told us that the picture tube has gone. And since, our bill and warranty card has been misplaced, we have to pay the full price for the picture tube. Since, there was warranty for seven years for picture tube and till today the product launch has not completed seven years. Hence, it is a fact that our tv is within the warranty period.
So on humanitarian ground, considering the fact of the above case, our picture tube should be replaced free of charge.
Hoping your action at the earliest.
