Address:

Sony Bravia full android 43 inch tv is not working since 10 days
I complained in nearby service centre
They first said tekon box problem is there
Then they said they wll Carry tv with them to check other problems
Then they said tekon box is perfect
Motherboard issue is there
And now they are saying as this model production is stopped so motherboard is not available.
I want to repair it
Do something
This is not the way to deal with customer
How its possible that branded things parts are not getting
Stop fooling us please
Do something
