My vizio tv shuts off occasionally and will not restart till it is ready

last night was the 4th time is has shut off by its self. Would not come back on for several hours. Has power (orange) light but will not power up screen (white light). VIZIO

The only thing I can think of is there may be a temperature sensor that shuts it down when it overheats and won't let you turn it back on until the temp has dropped. That doesn't sound like something you can fix at home. Contact Vizio. Support button at the top right.
