I had a Sony Bravia for 5 or 6 years before it stopped working. I took it to a Sony recommend technician to have it assessed a for repair. Which cost $300 just for the assesment.
I was told the main panel had failed and it would cost over $1200 to have the panel replaced less the $300 I had already paid for the assesment. You could imagine my disgust.
While I was contemplating which way to go (fix or replace), about two days later a Sony public relations representative called me.
He immediately offered a new replacement Sony TV, latest model (4k HD Android) in the same size and spec range. I didnt even get given the chance to complain about the old TV failing

.
Three days latter the TV arrived deliverd to my home. Two days after that a refund cheque of $300 (for the original assesment) arrive in the post .
6 Years later the TV is still going strong.
