How to Change Lamps on a Panasonic Pt- 52Lcx15 Projection TV


Lamps have a limited life. This includes the lamp on your Panasonic projection TV. When a bulb goes out or when they begin to dim from age, it is time to replace them. Fortunately, replacing the lamp bulb in your Panasonic TV is not difficult, but care must be taken to prevent injury and to ensure the bulb lasts as long as possible. For example, never touch the glass of the bulb with your bare fingers -- the oils from your hands can greatly reduce the life of the bulb.

Things You'll Need

  • Screwdriver
  • Gloves
  • Replacement bulb
  • Switch your projection TV off and wait until the red power indicator stops blinking. Once the power indicator stops blinking red, unplug the set and allow it to cool for 60 minutes before changing the lamp.

  • Grasp both sides of the front cover of your TV (the panel just below the screen) and pull forward until the panel pops off. You will now see the lamp housing.

  • Turn the locking knob on the front of the lamp housing counterclockwise until the housing opens. Gently pull the cover out and then down. You will now see the lamp unit, which has a handle in the center.

  • Remove the screw to the right of the handle of the lamp unit housing with the screwdriver. Gently pull on the lamp unit handle until the lamp unit pulls out.

  • Insert the new lamp unit, making certain that you are inserting it in the same way the old unit was installed. Be careful never to touch the bulb with your bare fingers (wear gloves when working with the new bulb). Push the lamp unit housing firmly into place with the handle and then screw in the screw to the right of the handle that holds the unit in place.

  • Close the lamp cover and turn the locking knob clockwise until it is locked into place.

  • Replace the front cover at the base of the screen. Plug in the TV and turn on the power. Check to see that the TV is working properly.

Tips & Warnings

  • Never work on a TV that has just been operating as you could be severely burned.
  • While an on-screen warning that your lamp needs to be replaced is designed into the TV, Panasonic recommends that you keep a spare bulb on hand in case the bulb goes out unexpectedly.
  • After replacing the lamp, the lamp hour meter should be reset so the TV can warn you when the new lamp needs to be replaced. Instructions for resetting the lamp hour meter will be included with your new bulb.
  • Always use a factory lamp, replacement part number TY-LA1000
  • Lamps contain mercury. Always dispose of them according to local laws and regulations.
