Purchased a Vizio 37″ LED 1080P TV. Set took too long recognize any video signal when changing channels and would mysteriously reboot on its own randomly. Tech Support of no value asked to speak to a supervisor twice. Told they would call back. After 3 weeks still no call. Wrote to VP of Operations. He did not respond nor did he have a supervisor respond.. Friend had same TV with same prob. Finally returned to store and purchased a Samsung which performs flawlessly. I would never purchase another Vizio.
