I have been pulling the DC power connector out of the television to get rid of the the blue light at night. While browsing Amazon for something else I came across a short cable with the right size male and female connectors to match the TV and a switch that plugs straight in. https://www.amazon.com/gp/product/B01D66D9PM/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
Now I can just flip the switch on and off to remove power to the TV. Very simple plug in fix.
