The machine starts, eventhe vent, but no image appears. All the lights, except the POWER SAVING one remain lights on.

  • Plug the projector into the wall and put it into standby mode. You should have already replaced the projector's lamp with a new LMP-P200.
  • Press the "Reset," left arrow, right arrow and "Enter" keys on the projector's control panel. Press them in the exact order listed here, one after another, and press each key for less than five seconds.
  • Turn the projector on with the "Power" button. Press the "Menu" key to enter the projector's menu settings.
  • Press the down arrow to navigate to the "Install Setting" menu and press the right arrow to select it. You should see the lamp timer at the bottom of the screen. If you have correctly reset the lamp timer, it will indicate 0 or 1 hours.
  • Press the "Menu" key to exit the menu system.

    Try this, it works on older LG TV models:

    Put the projector on. While holding down the Menu key on the projector, press and hold down the Menu button on the remote. Keep both buttons pressed for a count of at least 5 seconds.

    When the Service Menu pops up, release the Menu button on the remote control first and then the one on the projector after.

    Now you're in to the service menu, you need to find out which button on the remote brings up the Lamp Timer Reset function. This is where you're going to have to do a bit of trial and error. With the TVs, the remote button was the Mute key. There isn't a Mute key on the projector remote, so try the Lamp key first. If that doesn't work then try some other buttons. Here's the method.

    While holding down the Enter/OK on the projector, press and hold the Lamp key for five second. If this works then the lamp timer reset box should appear. Release the remote button first, followed by the unit button.

    Press Enter/OK on the remote to reset the lamp timer. If there's an On Screen Prompt to confirm, press Enter again.

    Press Exit on the remote to come out of the menus.

    Warning: Don't reset or change any other functions. The service menu isn't the place to be tinkering around with stuff you don't understand.

    LCD projector no signal message

    Usually means that the computer is not sending a signal out the the projector via the monitor cable. Most Windows based laptop computers allow you to connect to a second monitor by pressing the Fn + F7 or F8 key, once to allow just the projector, twice to allow both the projector and laptop screen and three times back to only the laptop.
