For three years it worked excellently. Suddenly I found a wide about 8" wide vertical white stripe in the center of the display panel. Various icons are shown but intermittent. A service engineer from your service center in Haridwar (Uttarakhand) visited and told us that the display panel has become defective. The only replacement of the panel is the solution.
If that is so kindly advise how to get it done and the warranty for the new panel.
Thanks
