It will be understandably difficult for you to enjoy watching a show if your RCA TV keeps turning itself off. It can do this automatically based on how the certain settings are adjusted. The clock, sleep timer and other time-based settings contribute to controlling how your TV behaves. In most cases, you will easily be able to program your TV so that it turns off when only you decide to press the power button.
Press the "Menu" button on the remote control.
