Once in a while, perhaps once a week, pressing the power button on the remote will have the red led on the TV turn off, but the screen stays black. Pressing any button on the remote does nothing, including the power button.
The only way to fix it is to unplug power from the I/O box (whatever it is called). Then the TV will turn on fine.
The TV says the software is up-to-date, so I am not sure what else I can do.
