least one hour before proceeding.

2. After the lamp has cooled, remove the cover of the

lamp compartment, located on the back of the TV.

3.	With a large Phillips or flat-blade screwdriver, loosen
	the two shiny screws securing the lamp cartridge
	until they disengage from the mating threads. These
	are captive screws and cannot be separated from the
	lamp cartridge.
4.	Fully open the bag supplied with the replacement
	lamp and set the opened bag aside.
5.	Gently grasp the handle of the lamp cartridge and
	pull the old cartridge straight out. See figure 3.

6.Without tilting or putting down the lamp cartridge, insert it into the opened bag. Close the bag while being careful not to let any glass particles fall out.

Installing the New Lamp Cartridge

1.Do not touch the glass parts of the new lamp car- tridge. Insert the new cartridge into the TV in the same orientation as the old cartridge. Push on the cartridge housing until it is fully seated.

2.With either your fingers or the screwdriver, gently tighten the two shiny screws. If using a screw- driver, AVOID OVERTIGHTENING!

3.Replace the plastic cover and retaining screws.

4.WASH YOUR HANDS THOROUGHLY, AS THIS LAMP CONTAINS MERCURY.
