Sony India — panel issue

Address:

Thiruvananthapuram, Kerala, 695020

Just 3 yrs before purchased this tv with cost of rs 37000. Now picture tube has failed. This is main component of tv.
Then what is the standard of sony named product?

As a lower middle class like me, how it is possible to pay again rs. 12, 154 / with in 3 yrs.. Already emi is going for personal loan taken for purchasing this tv.
How such lower middle class people would help sony with this kind of issue.

Could you please help me to reduce the estimation amount as it is huge amount from my financial situation.
