How to Change the Lamp in a Sanyo Projector
By Solomon Poretsky
Sanyo business projectors use a special high-pressure lamp to provide the light to generate an image. As the lamp gets old, it gradually fades and eventually fails. To keep the projector working, you will need to periodically replace the lamp. Given that lamp lives are usually measured in the thousands of hours, it will be a relatively infrequent procedure, but not doing it can lead to your projector not working when you need it or even to a lamp exploding inside the projector, damaging its internal parts.
Replacing the Lamp
Unplug the projector and allow it to sit unplugged for at least 45 minutes. This will let it cool down so that it is safe for you to open.
Flip the projector over so that its bottom panel is facing up and towards you.
Use your Phillips screwdriver to loosen the screw that secures the projector's lamp cover. Once you have removed the screw, use your fingernail or a thin edge to pry up the cover. Remember to save the screw for when you replace the cover.
Unscrew the two Phillips screws that hold the lamp assembly in the projector and set them aside.
Pull up on the old lamp assembly's bent-wire handle and gently remove it from the projector.
Remove the new lamp from its packaging and, using its bent-wire handle, place it into the projector in the place occupied by the old lamp.
Replace the two screws that hold the lamp in place by hand-tightening them. Replace the lamp cover and screw it back into place.
Resetting the Lamp Counter
Plug the projector back in and turn it on with the "Power" button on its remote control or top panel.
Press the "Menu" button on the remote control or top panel.
Use the down-arrow button to select the "Setting Menu," then press the right-arrow or the "Select" button to select it.
Scroll down to the "Lamp Counter" option and press the "Select" button.
Scroll down to the "Lamp counter reset" button and press the "Select" button to activate the feature. Use the down-arrow to select the "Yes" option, if necessary, then press "Select".
Confirm the reset by pressing "Select" one more time to select the "Yes" option in the "OK?" box. Once the lamp counter is reset, you can turn off the projector with its Power button or press the "Menu" button to exit the menu system.
Items you will need
Spare projector bulb
Always keep an extra bulb handy so that you have it when you need it.
If you attempt to replace the lamp without cooling the projector down, you could severely burn yourself.
Do not touch any of the glass parts of the lamp. The oils on your fingers can destroy their coatings and lead to the lamp failing quickly or exploding inside your projector.
