Although videocon is good tv making company but after 2 or 3 years their tv’s looses its picture quality .I have got Videocon challenger at my home .For two and three years it worked smooth but later on slowly it started loosing picture quality .I think sinceely it is almost useless .It depicts only black and white pictures now .I think we wasted our money and it is lying useless at my home .Besides it, its settings sometimes automatically changes and takes long time to restore .
