2. Safety Information
WARNING: Projector lamps operate at high temperatures and contain high-pressure mercury vapor. Improper handling can result in serious injury or damage.
- Always disconnect the projector from the power source and allow it to cool completely (at least 60 minutes) before attempting to replace the lamp.
- Do not touch the lamp glass directly with bare hands. Oils from your skin can cause hot spots and reduce lamp life. Use gloves or a clean cloth.
- Never operate the projector with the lamp cover removed.
- If the lamp breaks, avoid direct contact with broken glass and mercury. Ventilate the room and follow local regulations for disposal.
- Keep out of reach of children.
3. Setup and Installation
3.1 Unpacking
Carefully remove the new lamp and housing from its packaging. Inspect it for any signs of damage. If damaged, do not install and contact your supplier.
3.2 Tools Required
- Phillips head screwdriver (if required by your projector model)
- Clean gloves (recommended)
3.3 Installation Steps
- Power Off and Cool Down: Ensure the projector is turned off and unplugged from the power outlet. Allow at least one hour for the lamp to cool down completely.
- Locate Lamp Compartment: Refer to your projector's user manual to locate the lamp compartment cover. This is typically on the side or bottom of the projector.

- Remove Old Lamp: Loosen the screws that secure the lamp module in place. Gently pull the handle on the lamp module to slide it out of the projector.

4. Operating the Projector with New Lamp
4.1 Initial Power-On
After installing the new lamp and securing the cover, plug the projector back into the power outlet. Power on the projector. The new lamp should illuminate. Allow a few minutes for the lamp to stabilize and reach full brightness.
4.2 Resetting Lamp Timer
Most projectors have a lamp timer that tracks lamp usage. After replacing the lamp, it is crucial to reset this timer in the projector's menu. Refer to your specific projector's user manual for instructions on how to access and reset the lamp timer. Failure to reset the timer may result in inaccurate lamp life warnings or premature shutdown.

5. Maintenance
Proper maintenance can help extend the life of your projector and lamp.
- Air Filter Cleaning: Regularly clean or replace the projector's air filter as recommended by your projector manufacturer. A clogged filter can lead to overheating and reduced lamp life.
- Ventilation: Ensure the projector has adequate ventilation. Do not block air vents.
- Cool Down Cycle: Always allow the projector to complete its cool-down cycle after use before unplugging or moving it.
- Handling: When handling the lamp, avoid touching the glass bulb directly.
6. Troubleshooting
If you encounter issues after installing your new lamp, consider the following common problems and solutions:
- Lamp Not Turning On:
- Ensure the lamp compartment cover is securely closed and all screws are tightened. Many projectors have a safety switch that prevents operation if the cover is open.
- Verify the projector is properly plugged into a working power outlet.
- Check if the lamp module is fully seated and secured within the projector.
- If the projector indicates a lamp error, try resetting the lamp timer (refer to your projector's manual).
- Dim Image or Poor Picture Quality:
- Ensure the projector lens is clean.
- Check projector settings for brightness and contrast.
- Verify that the lamp timer was reset after installation. A lamp that appears dim shortly after installation might indicate an issue with the lamp itself or the projector's power supply.
- Lamp Flickering:
- This can sometimes indicate a loose connection. Re-seat the lamp module.
- If flickering persists, it may suggest an issue with the lamp or the projector's ballast.
- Short Lamp Lifespan:
- Ensure proper ventilation around the projector to prevent overheating.
- Regularly clean the projector's air filter.
- Avoid frequent power cycles or sudden shutdowns without allowing the lamp to cool down.
- While this replacement lamp is designed for optimal performance, individual lamp life can vary.
If these steps do not resolve the issue, consult your projector's original user manual or contact Technical Precision customer support.
