Vu televisions

I bought a VU 43 inch TV in 25/10/2019 for 16749. After the warranty period of one month my display had a blinking problem. There are no physical damages to the TV.
For the technician initial visit they have charged 1000 rupees which is very high for an initial inspection. After the visit they mentioned that the whole display needs to be changed which costs around 12000 which is almost close to the price of the TV. This is really insane price they are asking for the repair...for just one year why should we buy this TV for 16, 749.please kindly provide any suggestion that will benefit me.
