Summary: Purchased this TV from Amazon 3.5 years ago. Professionally installed with a beautiful picture and reliable performance until 2 months ago when vertical lines began to show on the screen. The intermittent burn out of the picture has progressed to a constant "plaid" set of lines on the screen. LCD Panel failure which will cost a fortune to repair. Very disappointed that such an expensive, top of line Sony TV fails in only 3 years.
