Rich bought a P50 Vizio that died after 6 months. He got a replacement, which lasted about a year and a half. Then the replacement died. All sound, no picture (intermittently). He's also been having issues with HDMI. Scott says that Vizio's have a known issue with failing HDMI ports. So try and plug into another one. But more often, the power supplies fail, so that maybe the problem. Rich adds to monitor the problem and maybe add surge protection. But also get back in touch with Vizio. The warranty may enable a return.
