I use to have the old vizio first one, never have that issue, but was obsolete and stop using so recently I decide to buy one cheap on eBay, encounter many issues, many crash, I have the same thing about turn on, so I decide to disconnect from power when was not use, but one time when turn on force me to reset due whatever crash issues. So I did and start back again, I notice the crash on media center back again and others, I disable email and google app. But the one disable that solve the issue and the rest of crash was disable media center, in my case eHomeMediaCenter, after clean data and disable that app on settings never turn on by himself, stay off and crashing on system stop too.
