I have had 3ea, 42" Vizio Plasma TVs go bad and 1ea 50" Plasma TV, having the Digital Tuner on my 50" Plasma go out twice in less than 2 years. After continued problems with 42" Plasmas I was offered an option to trade in the defective 42" (paid $1799) for a 50"($800 upgrade) ($2600) which I hoped was a better model. In less than 2 years the digital tuner has gone out twice. I have a 27" and a 32" cathode ray TV sets that have worked trouble free for 20 years. Although I have a lengthy support and warranty history, Vizio Customer Service can find no history of my service, registration, or purchases. read full review »
