We purchased Sony Bravia 55 inch 4k android TV from Sony center on Aug 2017 at velachery chennai.Hardly used 3 yrs and 2yrs we were in our hometown due to pandemic situation. Within 3 yrs couple of times display got problem.first time it was repaired by troubleshoot.now not recovered.Based on the brand value purchased hence realized all substandard material used.few of my friends were purchased from middle east still working good without any single problem.pls Don not purchase Sony TV from India.
