When Hormer turns on the TV to show Marge Korean Soap Operas, the receiver on the top of the TV shows cables connected to the back of the TV and buttons on the side of the TV. In the shot of Marge changing the channel, the cables and the buttons are gone. Then when Homer is shaving and tells Marge he's going to get one of the jobs for the self driving car company, the cables and the buttons are back on the TV.
