Xiaomi India — mi tv 4a panel problem

Address:

560015

I purchased mi led smart tv 4a 43inch on oct 13th 2018.
After 1year 4month the tv panel is having problems like white dot and blue vertical lines in between the screen.
I called customer service. But no use. My tv panel is under warranty.

I believe that mi tv wil be resolved by support. After my purchase i suggested my friends to purchase the same, but now...

I request mi india to replace the tv under warranty.
