About a year and a half ago I bought a Vizio P65 TV. The Model was C1 at that time. This model is apparently no longer available, apparently. The new model is E1 as shown here.
Just after a year, when the TV was out of warranty, two of the four HDMI ports failed. I paid about $400 for an out of warranty repair to replace the “Main Board” and the HDMI ports all work now. The repair required two folks, since the TV is very heavy and must be laid down on it’s face for a mainboard repair. Also the folks drove over 200 miles to reach my house, so I doubt if they broke even on the repair.
Now the TV is Rebooting
However, after this repair, about twice, or more, times per day, the TV seizes up and reboots.
When it reboots, almost always, but not always, the restart process starts with the screen showing a repeating pattern of the lower few rows of the screen. Then after about 10 seconds, the TV restarts showing the Vizio brand chevron. This example happened while watching the Dish Hopper.
