Of our four t.v.'s, this was my favorite. Gorgeous picture, handsome cabinet. It is an occasional unit, although approximately 3 years old, it probably had less than 200 hours on it. IT DIED! Took it to the repair shop [no warranty, of course!]. The tech determined that it was the power supply unit. When he phoned the parts supplier and started to tell him the make and model, the parts guy interrupted the tech and said, "Let me guess... you need a new power supply unit". $201.35 part/labor/tax. THANKS SAMSUNG! I'll be sure to rush right out and purchase another one of your 'highly rated' sets, and be sure to recommend your sets to all I meet. This was a 'deal breaker' for me. Next time....
