What kind of longevity are you getting out of these sets? I purchased a P75-C1 on July 11th, 2016 and it's already defective. It developed a black blob in the lower left corner where the back light is going out. I had to dump it for $50! I'm pretty ticked off I got less than 3.5 years out of a set that was so expensive, and heralded as a "Good Buy". And, it's not like I abused it. It was used in a non smoking home, kept cool, and used maybe 1.5 hours a day.
Fwiw, before the Vizio I had nothing but Panasonic Plasmas that are ALL still functioning just fine today, with the youngest being over 7 years old! I sure hope my LG B855 in the bedroom and the Samsung Q80R 75 I purchased to replace the Vizio last longer.
Am I right to be salty I didn't get more usage out of what is still a relatively "New" Tv? I'm not sure I will buy Vizio again.
