My Roku is not working. Last night, it said hot plug, the device was a little warm but not hot at all. I unplugged it. This morning I plugged it in. Totally cool, and it won't turn on. Says hot plug. Did it fry the plug.
Do you have a Vizio TV? Vizio TVs come up often when I search for “hot plug”.
I believe it means "hot plug" like "hot swap". It's not a temperature thing, but rather plugging something in to a system that is already up and running.
