I have a KD Sony Bravia that I bought late 2016, last week I received an update that turned my TV crazy. Starting with an initial set up loop then in the space of 5 days resulting to not making it past the boot up screen. Speaking to Sony, they recommended I take it to a registered Sony repair shop so I did. I paid £50 to get the TV looked at; they found the motherboard had suffered damage from the update. Now I have a choice to pay 400 to replace the motherboard when I bought the TV for 500. How can Sony do this and claim no responsibility or offer help? What can I even do with the TV now? Is it worth anything?
