TV shut off and won’t come back on and the power lights aren’t working

My Sharp (model LC-70LE660U) television randomly shut off and won’t come back on. i’ve tried everything on google. i’ve unplugged it for 10 minutes and held the power button down. i also unplugged it and held several combinations of buttons together while plugging it back in and nothing. i checked the plug in the TV and it’s connected.
