Hitachi TV Rear Projection Bulb Replacement Instructions
By Johnathan Cronk
Hitatchi specializes in high technology and services, including its line of HD rear-projection televisions. The television's picture and quality is powered by a mercury bulb that is housed within a lamp unit. The bulb has a limited life and will burn out over time. When the picture begins to turn dark or the color looks unusual, the lamp needs to be replaced. The "LAMP" indicator light may come on as well to alert you it's time for a new bulb. Replacing the lamp unit requires minimal tools and will ensure clear picture quality.
Turn the Hitachi television off and unplug the unit. Allow the unit to cool for a half-hour before replacing the lamp.
Pull the front cover outward to remove it from the unit. The cover is held in place by a snap on. As you pull the cover, the snap will disengage. You will now have access to the lamp door.
Remove the screw holding the lamp door in place. Use a Phillips screwdriver. Slide the lamp door off of the unit. The lamp is now revealed.
Unscrew the two screws holding the lamp in place. Remove the lamp from the television; hold the lamp handle and pull straight out.
Slide the replacement lamp into the television. Do not touch the glass bulb part of the lamp as this may shorten the life of the bulb.
Replace the screws on the new lamp unit. Tighten the screws to secure the lamp to the television. If the screws are loose, the television and lamp may not work properly. Replace the lamp cover and secure the screws.
Push the front cover back onto the television. Align the snap on and push inward holding the left and right side until you hear a snap. The cover is now secured. Plug the Hitachi back in and power on the TV.
