How to Reset the Lamp Hours on the TV
When you replace the lamp bulb on a TV it is a good idea to also reset your lamp hours on the TV, so that you know how many hours the lamp has run before it needs to be replaced again. This is good if your bulb is warranted for life expectancy and also if you are curious about the time amounts you have been using your TV. Resetting the lamp hours is a simple process using the remote and the reset code instructions.
Things You'll Need
Press "Display" on the remote, followed by the 5 button, then the sound up key, and "Power On." Do this while the TV is in Standby mode.
Then press "Jump" 3 times to enter the DE Service menu. The TV screen will display the total lamp time hours.
Reset the lamp time by pressing channel 3, then mute, then enter. This will put your lamp counter back to 0.
With the TV on, press and hold down the "Menu" button on the TV. Now press and hold down the "Menu" button on the remote. Hold both buttons down for 5 seconds until the service menu is displayed on the TV screen. Release the remote "Menu" button first and then on the TV.
