TV Won't Turn Back On Right Away

I have a Samsung PN64F8500. If I turn the TV off after having it on for a while it won't turn back on right away. The red indicator light simply flashes at me. Sometimes after a minute the sound will come on but no display. If I wait a while after turning it off then eventually it will turn back on just fine. It's almost as if it needs a while to cool down or rest or something.

I have no idea about this stuff - thanks in advance for anyone's help!
