Sony India — refund or replace

I purchased sony bravia 108 cm (43 inches) full hd smart led tv klv-43w772e (2017 model) and serial no.309877) on 2.10.2018 last month when the tv screen looked good, picture quality was also good. Now the tv screen is not clear from now on and currently the tv screen shows the blurring, brightness sharpness is also decreasing in the color of tv tv turns off when it runs, it takes time to turn on
The distributor i bought from the tv was told my problem, but no solution was made by him nor any satisfactory answer was given. So, i request you please help me. I am very sad and depressed due to this kind of please. Send the engineer to your company as soon as possible, immediately improve the tv, i am doing a copy of the invoice and the scan copy of the warranty card with complaint.
