To do this, press the ENTER button on the TV and the MUTE button on the remote at the same time. After 5 seconds the screen should come up and it will read "Lamp use time...Total lamp use time ....lamp reset" Press the center button on your remote (the circle button right in the middle of the four directional buttons) and you will be reset to -0- again. Your orange light should now be off.
