Sony India — tv monitor blinking issue

Dear sir,
I brought sony tv klv-32r422b in year september 2014. The monitor for same stopped working (Blinking) in nov 2019. Just after 5 year of normal usage. I checked with service center, they told company stopped producing this model and it's components. I am really disappointed by sony which has huge brand value and producing faulty products. And they stop manufacturing so they don't have to support even 5 year old products. As a user how can i trust the brand. I feel cheated by rs 31000 (Price of tv). I bet even if it was under warranty they would not have been able to replace monitor problem, because they don't have one.
Is there a rule which says manufacturing company has to support all components for x year??
