Sony India — Single horizontal line in the TV Screen

Address:

Kothat House, Poomkavu, Alappuzha

Its been 2years and 6months, I purchased a TV worth 61000.00. Yesterday I found a horizontal line in the TV screen and I called for Service and they told send a photo and sent it. After 1 hour they calles me back and said display need to change and including service 16500.00. My concern is not this service charge, why we are buying a branded TV like Sony because we are trusting their name and for long term use. Who knows after service how long it will work without further complaints. So I request to you please do something and don't break our trust. Thanks
