  If your Sharp LED TV isn't powering on, ensure the power cord is securely connected to both the TV and the power outlet. Try unplugging the power cord, waiting 60 seconds, and then plugging it back in before turning the TV on. Also, other devices may be interfering with your TV. Try turning off one device at a time to determine which device is causing interference and move it further from the TV to eliminate the interference.
