Sony India — Horizontal line on screen

I had purchased sony kd-43x7500e two years back. Now screen appearing with horizontal line and when i contact sony quoting me 14000 rupees charge for repair (Saying part to be replaced). Display is the main content in tv that’s the reason i choose sony but sony is saying no guarantee on electronic components, may lead to defective any time or next minute after warranty.
I agree too on no guarantee on electronic products may spoil any time but not with in short period that too an international brand company. Also sony doesn’t have answers to customer queries except saying warranty expired and i strongly object this is just fraudulent manufacture assembled with cheap electronic components and high cost selling price by tagging sony brand name
