Query: Poof goes the TV

Like other reviewers, my TV also went poof after having it about 4 years (guess I should consider myself lucky in getting a bit more time than others). Repair looks to be $700 plus to replace a power switch. I'm very disappointed in this Sony; obviously a poor design. I'm in the market for another TV, not sure it will be a Sony.
