Sony India — supplied used or duplicate tv

I had purchased a sony 40" lcd tv from adishwars electronics jayanagar branch. It only existed for 10 years. Suddenly the tv screen started blinking and we gave it to authorised service centre which is in jayanagar bangalore, karnataka. They say that part is not available. This leads me to think weather it's original or duplicate as sony itself doesn't have the part available. I would like you to take action against them. The service center name is abivrudhi tech.
