Lamp-Cartridge Replacement
Removing the Old Lamp Cartridge
1. Turn off TV power and allow the lamp to cool for at
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.
Refer to figures 1 and 2. Use a #2 (large) Phillips
screwdriver to loosen the screw securing the cover.
Keep the screw and cover for re-installation
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.
CAUTION: Do not tilt or rotate the cartridge,
as small glass fragments may fall out.
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.
